Plastic drain board with sounding hole

Abstract

The invention relates to a plastic drain board with a sounding hole. The plastic drain board is composed of a plastic core veneer, a nonwoven cloth and an anti-clogging part; the nonwoven cloth covers the drain core veneer; the anti-clogging part is inserted in one end, driven into the ground, of the plastic drain board; a sounding hole in the length direction is formed in the solid body of the plastic core veneer and has a diameter greater than 1mm. Compared with an existing sounding plastic drain board, the plastic drain board with the sounding hole has the following beneficial effects: no metal conductor needs to be arranged in the plastic drain board so that a lot of metal materials can be saved, and the process is simple and the cost is low; 2, a spring steel wire having the diameter of less than or equal to 1mm is directly inserted in the sounding hole and capable of directly measuring the actual depth of the plastic drain board driven into the ground, and the measurement is accurate and the operation is simple; and the purposes of falsification and cheating on labor and materials cannot be achieved no matter which means are adopted.

Description

technical field [0001] The invention relates to a depth-measuring plastic drainage board, in particular to a plastic drainage board structure with a depth-measuring hole, belonging to the technical field of soft foundation materials. Background technique [0002] Plastic drainage board is an indispensable material in the construction of saturated viscous soft foundations such as silt, silty soil, and flushing fill soil using the drainage consolidation method. It is inserted into the soft soil foundation through the plug-in machine. Under the action of the upper preload, the interstitial water in the soft soil foundation will be discharged from the plastic drainage board to the upper sand layer or horizontal plastic drainage pipe, and then discharged from other places to accelerate the soft foundation. Consolidation. Therefore, the consolidation depth of the soft soil foundation is determined by the length of the plastic drainage board vertically driven into the ground. In ...

Problems solved by technology

This method has undoubtedly played a positive role in restricting cutting corners and materials, but there are still loopholes and disadvantages: 1. The wire can be artificially twitched so that the length of the wire is less than the length of the plastic drainage board; Putting metal wires in order to measure the length of the plastic drainage board driven into the ground will undoubtedly increase the cost of materials and production, waste a lot of metal resources, and the gain outweighs the gain
