Plastic drainage board It is a commonly used material in foundation reinforcement, soft soil foundation treatment and other projects. It can improve the performance of foundation and the stability and durability of engineering structures through the mechanisms of drainage, decompression and accelerated consolidation. However, plastic Drainage plate During the construction process, especially the control of verticality, it has an important influence on the drainage effect and engineering quality.
一. The importance of verticality requirements for plastic drainage boards
The control of the verticality of the plastic drainage board can determine the smoothness and drainage efficiency of the drainage channel. If the drainage board cannot be kept vertical during laying, it may lead to poor drainage and obstructed water flow, which will affect the consolidation speed of the foundation and the quality of the project. Insufficient verticality may also cause the deformation or fracture of the drainage board under load, reducing its service life and overall performance. Therefore, it is necessary to strictly control the verticality of the plastic drainage board.
二. Control method of verticality of plastic drainage board
1、Equipment selection: Select a board insertion machine with high precision and high stability to lay the drainage board. The plug-in machine should be equipped with a guide frame verticality adjustment device to ensure that it is always perpendicular to the ground during the installation process.
2、Construction operation: Before construction, the site should be leveled to ensure that there are no debris and potholes. When setting up the drainage board, it is necessary to strictly control the positioning accuracy and horizontality of the board insertion machine to ensure that the drainage board is vertically inserted into a predetermined depth. It is also necessary to regularly check the verticality of the plug-in machine and adjust the deviation in time.
3、Quality monitoring: During the construction process, full-time quality monitoring personnel should be set up to monitor and record the verticality of the drainage board in real time. If it is found that the verticality deviation exceeds the specified range, the construction should be stopped immediately, the cause should be identified and corrective measures should be taken.
三. Application of verticality requirements of plastic drainage boards in practical projects
In actual projects, the verticality requirements of plastic drainage boards are generally determined according to factors such as specific engineering requirements, geological conditions, and specifications and models of drainage boards. Under normal circumstances, the allowable deviation of the verticality of the plastic drainage board should be controlled within ±1.5%Only within this can the drainage effect and project quality be ensured.
For example, in infrastructure construction such as highways and railways, plastic drainage boards are commonly used in soft soil foundation treatment. At this time, the verticality control of the drainage board is very important. If the verticality is insufficient, it will lead to poor drainage, which will affect the consolidation speed and stability of the foundation. Therefore, during the construction process, the verticality of the drainage board must be controlled in strict accordance with the design requirements to ensure the smoothness and drainage efficiency of the drainage channel.
Plastic drainage boards can also be used in water conservancy projects, such as embankment reinforcement and reservoir seepage prevention. In these projects, the verticality of the drainage board should be strictly controlled to ensure the drainage effect and project safety.
