Improved draining plate

Abstract

The invention discloses an improved draining plate. Transverse lateral supporting plates and longitudinal supporting plates are additionally arranged on the basis of the structural form of a plate core of a traditional draining plate, so that the rigidity of the plate core of the draining plate is improved, the deformation resisting capability of the draining plate is improved, and thus the influence of deformation of the draining plate on the draining amount is weakened. The plate core and a filter membrane are bonded through the transverse lateral supporting plates and prevented from sliding and deforming, so that the draining plate is not likely to be blocked, and strengthening efficiency is higher. The draining plate is made of degradable materials, so that the problems that settlement continues, the subsurface structure is damaged, and soil is contaminated are solved. Besides, the improved draining plate is simple in technology, and factory operation improvement is facilitated.

Description

technical field [0001] The invention belongs to the technical field of drainage boards for soft ground treatment, and in particular relates to an improved drainage board that can promote drainage, improve reinforcement effects, and is degradable and environmentally friendly. Background technique [0002] At present, drainage boards are commonly used for drainage in soft foundation treatment, see attached figure 1 and 2 , the traditional drainage board is made of a board core (1) and a filter membrane (2). The plate core (1) is composed of a central support plate (1-1) arranged horizontally and a plurality of slotted teeth (1-2) fixed vertically on the central support plate (1-1) and arranged at equal intervals. The slots (4) (the slots are the gaps between adjacent slots) are used as channels for drainage and exhaust of the foundation soil, and the filter membrane (2) is coated on the outside of the plate core (1) to play the role of reverse filtration to prevent soil Bod...

AI Technical Summary

Problems solved by technology

However, in actual engineering, it is found that the drainage board will be bent and deformed with the settlement of the foundation, and even twisted and folded, which will greatly weaken the drainage effect of the drainage board; the traditional drainage board only has the tip of the core alveolar and the filter membrane. Contact, the small contact area makes it difficult for the two to stick together, and the two are easy to slide each other, which is easy to cause soil particles to enter the board core and cause siltation and blockage; after the foundation treatment is completed, the drainage board in the foundation still continues to consolidate the soil The drainage channel will cause continued settlement, and the leftover drainage board will pollute the foundation soil, which will affect the future underground structure (pile, ground connection wall, etc.) and endanger the safety of the superstructure
