How to reasonably configure construction machinery for earthwork engineering?

Release time: 2020-09-10 16:41:53 Source: Bulldozer

Earthwork is one of the more common infrastructure projects, such as water conservancy projects and highway infrastructure projects. It occupies an important position in the construction of earth and stone works. In earth and stone works, it must be selected according to the conditions of the construction site, construction technology, and construction tasks. Construction machinery and equipment. The mechanical configuration should follow the following principles:


How to reasonably configure construction machinery for earthwork engineering?


1.The selected model should have better economy


The unit price of construction is the basis for the economic selection of construction machinery. The operating costs of construction machinery and the consumption of fixed assets of construction machinery are all related to the selection of construction machinery. When large-scale construction machinery is used for construction, although a relatively large one-time investment is required, it can be apportioned in a relatively long period of time, and will not have a relatively large impact on the project cost. Therefore, when selecting construction machinery, the relationship between construction machinery cost and engineering quantity must be weighed, and the reliability and advancement of construction machinery should be thoroughly considered. These are important effects of construction economic benefits. factor.


2. Project conditions and construction machinery should be adapted to each other


The construction conditions of earth and stone works are changeable and complicated, and the construction area is relatively large. In-depth consideration should be given to project quality requirements, construction section size, transportation distance, construction site area, construction site climate, project soil conditions, project topography, etc., and select suitable construction machinery based on this. In addition, construction machinery with suitable capacity should be selected according to the requirements of the engineering volume and the project schedule, to the greatest extent possible to avoid the low utilization rate of the construction machinery and the delay of the construction period due to the overcapacity of the construction machinery. If the construction conditions permit, the construction machinery models and construction machinery models that can meet the construction content should be selected as far as possible.


3. Ensure construction safety and project quality


According to the technical requirements of earthwork engineering, to ensure the quality of the project, the selection of suitable construction machinery is an important factor. If the project has high requirements for construction technology, in order to ensure the efficiency and quality of the project, special construction machinery or high-performance construction machinery should be selected. However, it should be noted that one-sided pursuit of high-performance special construction machinery is strictly prohibited, and the versatility of construction machinery should be effectively combined under the condition that the project quality is satisfied. In addition, the safety performance of the selected construction machinery must have high reliability.


4. Reasonable combination of construction machinery


When carrying out mechanized construction, a reasonable combination of construction machinery must be made, including the configuration of the number of construction machinery, the type of construction machinery, and the performance of the construction machinery. For the same type of construction machinery and equipment, construction machinery and equipment with higher work efficiency and larger work capacity should be selected. Generally speaking, in order to effectively improve the efficiency of collaborative operations, the number of combined construction machinery should be appropriately reduced. In order to facilitate maintenance, management, and scheduling of construction machinery, there should not be too many types of construction machinery. In addition, construction machinery with greater productivity and work capacity should be selected, so that the efficiency of construction machinery can be fully utilized. During the construction of large-scale earth and stone works, the production capacity and construction design of construction machinery should be used as the main basis. The supporting combination of construction machinery shall be calculated in detail in accordance with the specifications to ensure that all construction machinery configured in the construction process meets the requirements for construction use. The specifications require reasonable determination of the performance, model and quantity of construction machinery supporting combinations.
