1. Static pressure construction preparation of steel sheet pile
Before construction, sufficient preparation work needs to be carried out. First, the construction site needs to be cleared to ensure it is flat and free of obstacles. Secondly, you need to check whether the static pressure equipment is normal and prepare all the required materials. Finally, technical training and safety education need to be provided to construction personnel to ensure that they understand the construction process and safe operating procedures.
2. Steel sheet pile selection
According to the construction requirements, select the appropriate steel sheet pile. Generally speaking, the length and width of steel sheet piles should be selected according to the needs of the project, while also considering their strength and durability. When selecting steel sheet piles, you also need to pay attention to factors such as quality assurance and performance parameters.
3. Installation of static pressure equipment
When installing static pressure equipment, you need to pay attention to the following points: First, you need to select appropriate static pressure equipment according to construction requirements, and carry out accurate installation and debugging. Secondly, it is necessary to ensure the stability and safety of static pressure equipment to avoid safety accidents during the construction process. Finally, hydrostatic equipment needs to be inspected and maintained regularly to ensure it is functioning properly.
4. Steel sheet pile insertion
When inserting steel sheet piles, you need to pay attention to the following points: First, you need to ensure that the steel sheet piles are flat and clean to avoid affecting the construction quality. Secondly, when inserting the steel sheet pile, it needs to be sunk vertically into the soil and kept stable. Finally, the insertion depth and spacing of steel sheet piles need to be determined based on construction requirements and geological conditions.
5. Steel sheet pile docking
When docking steel sheet piles, you need to pay attention to the following points: First, you need to ensure that the docking location is flat and clean. Secondly, the docking position needs to be fixed with professional connectors and its stability and sealing must be ensured. Finally, the connected steel sheet piles need to be inspected and adjusted to ensure that they meet the construction requirements.
6. Static pressure fixation
When fixing static pressure, you need to pay attention to the following points: First, you need to select the appropriate static pressure equipment and pressure size according to the construction requirements. Secondly, the static pressure equipment needs to be accurately placed on the steel sheet piles, adjusted and fixed. Finally, hydrostatic equipment needs to be inspected and maintained regularly to ensure it is functioning properly.
7. Soil reinforcement
During the construction process, the soil needs to be reinforced to improve the stability of the soil and reduce the occurrence of problems such as settlement. The specific methods are as follows:
(1)Soil reinforcement materials
Select appropriate soil reinforcement materials such as cement-soil mixing piles, lime piles, etc. according to actual conditions.
(2)Soil reinforcement sequence
Carry out reinforcement processing in the order of first deep and then shallow to ensure that the reinforcement effect meets the expected requirements.
(3)Soil reinforcement quality control
The quality of the reinforced soil should be tested, and the next step of construction can only be carried out after the soil's strength and bearing capacity and other indicators have been tested.
8. Static pressure adjustment
The following points need to be noted when adjusting static pressure:
First, the static pressure equipment needs to be accurately placed on the steel sheet piles, adjusted and fixed to ensure the horizontality and verticality of the top of the steel sheet piles. Secondly, the reinforced soil needs to be tested and analyzed to determine the actual bearing capacity of the soil foundation based on the actual results. The static pressure equipment is adjusted to achieve the best results, and finally the static pressure equipment needs to be inspected and maintained regularly to ensure its normal operation.
9. Remove steel sheet piles
When the steel sheet piles need to be pulled out after the construction is completed, the following points need to be noted:
(1) It is necessary to ensure the time and sequence of pulling out. Before pulling out the steel sheet piles, it is necessary to check the surrounding environment.
Check the equipment and make sure it is safe and reliable before proceeding with the extraction operation.
(2) Ensure safety
During the process of pulling out steel sheet piles, it is necessary to ensure the stability and safety of the equipment to avoid safety accidents.
(3)Cleaning
The pulled out steel sheet piles need to be cleaned and processed for next use.
Summarize
The steel sheet pile static pressure construction process mainly includes the above aspects of work. Each step is an indispensable and important link. Only by carefully operating in accordance with the prescribed process can the quality and safety of the project be guaranteed. At the same time, during the actual construction process, It is necessary to respond flexibly and make timely adjustments according to specific circumstances to ensure the best results.
