Highway construction projects in our province have achieved rapid development in a short period of time with the increasing investment in national infrastructure construction. Road mechanization construction is an important way of modern road construction. In the management of highway construction machinery, road construction management mechanized production power rated limit is the basic principle of machinery management.
- The main factors affecting the cost of road mechanization construction are.
- First, the rate of mechanical equipment intact.
- Second is the utilization rate of machinery and equipment.
- Third, the utilization rate of machinery and equipment.
Highway engineering machinery and equipment utilization rate is affected by a variety of factors, including the reasonable configuration of machinery, highway engineering construction site conditions, mechanical operators and the cooperation between machinery are affected by the mechanization of construction management costs.
1 The main factors affecting the cost of road mechanization construction
Modern highway construction is an important way to achieve road mechanization, in modern highway construction, the main factors affecting the cost of road mechanization construction are the following three points.
First, the rate of mechanical equipment intact. Mechanical equipment intact rate refers to the ratio between the total time and the total duration of mechanical equipment intact during the construction of highway projects. Mechanical equipment intact rate is an important indicator to assess the road construction machinery, but also the main factor of the cost of machinery.
Second, the utilization rate of machinery and equipment. Equipment utilization rate of high and low assessment of two situations, in the case of reasonable configuration of machinery and equipment, will not produce mechanical utilization rate is not high; in the case of changes in construction conditions, if the occurrence of unforeseeable other factors will affect the utilization rate of machinery and equipment.
Third, the utilization rate of machinery and equipment. Highway engineering machinery and equipment utilization rate is affected by many factors, including the reasonable situation of mechanical configuration, highway engineering construction site conditions, mechanical operators and mechanical cooperation between the situation, these issues affect the mechanization of construction management costs.
2 highway mechanized construction cost management problems
The comprehensive mechanical construction cost management problems at this stage in our province are mainly in the following three aspects.
First, there is a contradiction between management measures and machinery configuration. Highway construction period is long, there are many are inter-year projects. Machinery configuration and personnel deployment will also change greatly during the construction period, which will lead to mutual contradictions between personnel and machinery configuration. Highway construction originally has more points, long lines, wide and other characteristics, the mutual deployment between construction personnel and machinery often occurs, often make mechanical management can not take into account;.
Second, the road construction machinery and equipment management is not good. During the construction of highway projects, the deployment of personnel and machinery between each other often occurs, for the management of highway engineering machinery will have a partial absence. Not to mention the driving personnel and mechanical repair personnel pre-service training work, this phenomenon will lead to high maintenance costs of machinery and equipment, machinery and equipment does not play its normal operating efficiency.
Third, the road construction machinery and equipment maintenance is not timely. The timely maintenance of mechanical equipment and maintenance is an effective means of work to continue the mechanical efficiency of machinery and equipment in the rated working time. Equipment maintenance in a timely manner can also ensure that the mechanical equipment intact rate. Highway construction machinery in the construction period lack of necessary maintenance and maintenance, directly affect the equipment failure and construction efficiency, serious will affect the overall progress of the project and construction quality, increase the construction cost and construction equipment cost expenditure.
3 road mechanization construction cost management measures
3.1 Construction machinery configuration management measures
In the management of highway construction machinery, the main principle of machinery and equipment management is to apply the rationality of mechanical configuration to the management of actual construction. In the actual construction process of highway engineering, because the construction party only cares about short-term interests, it will only compress the quantity of machinery applied in the construction of highway engineering to the minimum when selecting machinery to ensure the maximum profit.
In the management of highway engineering construction machinery to choose the number and type of highway engineering construction machinery according to the actual amount of work that can occur, in order to improve the efficiency of mechanical construction. In the choice of construction machinery technical combination to pay attention to the following three aspects: First, the work capacity of construction machinery to be slightly greater than the total amount of road works plan to ensure the full play of mechanical production efficiency, to ensure the utilization rate of machinery and work efficiency; Second, the main production machinery for road works to choose with the mechanical construction, the choice of mechanical construction with the work efficiency to be slightly greater than the main production machinery power, so as to play Out of the main production machinery all the efficacy; Third, a variety of other traction machinery and units to achieve an adaptive configuration can be, to avoid mechanical power beyond the budget of mechanical selective program.
In the road construction machinery selection machinery configuration to rationalize the selection of mechanical configuration, in mechanical equipment can not meet the road construction needs, according to the construction unit internal mechanical configuration standards, to lease and other forms to meet the needs of road construction machinery and equipment to ensure the economic benefits of the project.
3.2 Construction machinery technical performance management
Construction machinery technical performance management is to ensure the mechanical utilization rate and integrity of the fundamental guarantee. To ensure the management of technical performance of construction machinery from the following five aspects.
First, the establishment of a sound basic mechanical system construction. The basic mechanical management system construction will make the mechanical equipment intact rate and work time is guaranteed, more can promote mechanical equipment to improve efficiency and create benefits.
Second, to ensure that the state of mechanical equipment is intact. Mechanical equipment intact refers to the appearance of neat and intact, tire inflation to adapt to the construction site driving road requirements, hydraulic system in good working condition without leakage, brake system device sensitivity to meet safety standards, no oil leakage, gas leakage, water leakage;.
Third, the establishment of a sound mechanical equipment file management system. Mechanical equipment maintenance records can reflect the maintenance and use of machinery within a certain range, reflecting the replacement status of mechanical parts, to facilitate mechanical repair and maintenance.
Fourth, the highway engineering machinery and equipment running state management. Highway engineering machinery and equipment operating state refers to the normal state of the mechanical drive system to ensure that the mechanical sensitivity, normal hydraulic system, normal braking system.
Fifth, the full rated production power management of machinery and equipment. Compression of the full rated power management is also an important management content in construction mechanization, conditional restrictions on the full rated power of machinery and equipment is mainly aimed at achieving the basic guarantee of construction mechanization efficiency, can save costs from fuel consumption and other aspects of mechanical management.
3.3 Highway engineering construction machinery safety management
In the process of highway engineering construction, mechanical construction safety guarantee is a basic content, to ensure the safety of mechanical production is to ensure the safe production of highway engineering, to ensure the safe production of machinery to fully implement the safety production responsibility system. Mechanical production site to set up a full-time safety officer, rationalize the cooperation between machinery and machinery, rationalize the cooperation between machinery and personnel, to ensure the safe production of work. Put an end to mechanical failure operations, put an end to machinery without overloading behavior, and put an end to operators without certification.
Reduce production costs, improve efficiency is the main goal of road mechanization construction. Improve efficiency is the main way to protect the road construction revenue, to protect the mechanical construction cost compression. Modern highway construction is realized through highway mechanization as an important way. The main factors affecting the cost of highway mechanization construction in modern highway construction are the following three points: one is the rate of mechanical equipment intact; the second is the utilization rate of mechanical equipment; the third is the utilization rate of mechanical equipment.
