Example Embodiment

[0011] The present invention will be further explained below in conjunction with the drawings:

[0012] As attached figure 1 , 2 As shown, the non-woven fabric 2 is wrapped around the periphery of the plastic core board 1 to form a water-permeable plastic drainage board; the anti-blocking member 3 is inserted into the end of the plastic drainage board that is driven into the ground; the plastic core board 1 is provided with a Along the length of the sounding hole 101, the diameter of the sounding hole 101 is 1.2 mm.

[0013] When it is necessary to measure the depth of the plastic drainage board driven into the ground, use a spring steel wire with a diameter of 1mm and a certain length, directly insert it into the sounding hole 101 and gradually lower it; when the end of the spring steel wire is subject to anti-blocking parts 3 When obstructed, the steel wire cannot continue to be lowered. At this time, the lowering length of the steel wire is the depth at which the plastic drainag...

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 ...
