AI Technical Summary

Technical Problem

Traditional plastic drainage plates are prone to retraction during insertion, the application effect of filter membrane blockage, and the bending stiffness is low, which is easy to bend, twist, and fold, affecting the drainage effect.

Method used

A plastic drainage body with a tubular structure has groove teeth and filter holes on the outer surface of the board core, and annular clamping strips are provided on the inner surface. The supporting insertion device includes an inner cylinder and an outer cylinder, and the stability of insertion and retraction is ensured through a vibration device and a clamping device.

Benefits of technology

It improves the efficiency of pumping and drainage, reduces the phenomenon of retraction, avoids filter membrane blockage, enhances bending resistance, and extends the service life of the drainage plate.

Abstract

The present invention discloses a plastic drainage body and a matching insertion device for soft foundation treatment in the field of soft foundation treatment technology. The plastic drainage body includes a tubular plate core and a filter membrane wrapped around the outside of the plate core. The outer surface of the plate core is evenly distributed with groove teeth, and filter holes are arranged between adjacent groove teeth. The inner surface of the plate core is provided with an annular clamping strip; the insertion device includes an inner tube and an outer tube that are mutually sleeved, and the tail ends of the inner tube and the outer tube are provided with a vibration device, the front end of the inner tube is provided with a cone head, and the inner tube is provided with a clamping device. The tubular structure of the plastic drainage body of the present invention provides a larger space for air extraction and drainage, which can improve the working efficiency; the plastic drainage body with a tubular structure greatly enhances its bending resistance, greatly avoiding the bending, twisting and folding of traditional plastic drainage boards; the insertion device utilizes a structural form combining an inner tube and an outer tube, which can not only protect the drainage body during insertion, avoiding the smearing effect of filter membrane blockage during the insertion process of the traditional drainage board, but also can stably detach from the drainage body during the withdrawal process, avoiding the back-carrying phenomenon of the traditional bayonet structure.
