In construction engineering, pile foundation engineering is an important part of infrastructure construction, and its quality directly affects the stability and safety of the entire building. Therefore, how to formulate a scientific and reasonable construction plan and improve the construction quality and efficiency of pile foundation engineering is a problem that every construction enterprise needs to face. This article will take the construction of the general contracting pile foundation project as an example, and the formulation and implementation of the construction plan.First of all, we need to clarify the basic process of construction general contracting pile foundation engineering. Generally speaking, the construction general contracting pile foundation project mainly includes the following steps: design, resource allocation, construction technology selection, construction process determination, construction key points, construction difficulties and quality inspection standards formulation. In this process, we need to select the appropriate construction technology and process flow according to the specific engineering conditions and requirements, and formulate a scientific and reasonable construction plan.
In the construction of general contracting pile foundation engineering, rotary drilling bored pile is a commonly used construction technology. This process has the advantages of high construction efficiency, strong adaptability and controllable quality. However, there are also certain difficulties in the construction of rotary bored piles, such as pile foundation design, quality inspection of mud wall protection hole-forming cast-in-place piles, etc. Therefore, we need to conduct detailed analysis and research on these difficulties in the construction plan and propose effective solutions.
In terms of resource allocation, we need to reasonably allocate resources such as manpower, material resources and machinery and equipment according to the requirements of the construction plan. For example, for the construction of rotary bored piles, we need to configure professional rotary drilling machine operators, concrete pouring workers, quality inspectors, etc. At the same time, we also need to prepare enough concrete, steel bar, mud and other materials, as well as rotary excavators, mixers, drill bits and other equipment.
In terms of determining the construction process, we need to determine the specific construction steps and operation methods according to the requirements of the construction plan. For example, for the construction of rotary bored piles, we need to first design the pile foundation, then carry out rotary drilling, then carry out the construction of mud wall protection hole-forming cast-in-place piles, and finally carry out quality inspection.
In terms of grasping the key points of construction, we need to grasp the key steps and key parameters in the construction process according to the requirements of the construction plan. For example, for the construction of rotary bored piles, we need to control the depth, diameter and verticality of the bored holes to ensure the quality of the cast-in-place piles.
In terms of solving construction difficulties, we need to propose effective solutions according to the requirements of the construction plan. For example, for the quality inspection of mud wall protection hole-forming cast-in-place piles, we can use ultrasonic transmission method, static load test method and other methods for inspection.
In terms of the formulation of quality inspection standards, we need to formulate scientific and reasonable quality inspection standards according to the requirements of the construction plan. These standards should include the design requirements, construction process requirements, quality inspection requirements and other contents of the pile foundation.
In general, the formulation and implementation of the construction plan of the construction general contracting pile foundation project is a systematic and complex process. We need to select the appropriate construction technology and process flow according to the specific engineering conditions and requirements, reasonably allocate resources, grasp the key points of construction, solve the construction difficulties, and formulate quality inspection standards to ensure the construction quality and efficiency of pile foundation engineering.
