Problems solved by technology

[0003] The materials used in the existing anti-seepage and water-stop construction are mainly commercial concrete, cement soil and steel plate water-stop piles, etc., and there are the following problems: First, due to the lap joint between piles and piles in the anti-seepage and water-stop construction, plain concrete The lap joint during the construction of the anti-seepage wall, as well as the leakage caused by sediment and collapsed holes; the second is that the wall stress causes cracks in the formed wall to cause leakage; the third is that groundwater is corrosive to cement soil and concrete

Embodiment 1

[0027] Composite ultra-strong anti-corrosion and seepage-proof wall material production: see figure 1 , with PVC as the main material, adding several kinds of additives, after stirring and high temperature, it is extruded into a flat plate through a mold. The wall material is 800mm wide, 6mm thick, and 12000mm long; there are connecting devices on both sides of the wall material, and one It is a groove, and one side is a convex groove. When using it, use special equipment to insert the convex groove of the rear wall material into the groove of the front wall material that has been constructed, so that the front and rear wall materials are connected to each other to form an anti-corrosion and water-proof curtain. system.

Abstract

The invention discloses composite ultra-strong corrosion preventing and seepage stopping wall materials and an application method thereof. PVC serves as the main material of the wall materials, several additives are added and are extruded and formed through a die after being stirred and subjected to the high temperature, connecting devices are reserved on the two sides of the wall materials, a concave groove is formed in one side, and a convex groove is formed in the other side. During using, the convex groove of the rear wall material is arranged in the concave groove of the constructed front wall material through a special device in a sleeved manner, and the front wall material and the rear wall material are connected with each other in a hooked manner, and a corrosion preventing and water stopping curtain system is formed. According to the needs, the wall materials can be machined to be in the shapes such as a flat plate, a double curvature arch and a multi-curvature arch, wherein the flat-plate-shaped wall material has the functions of corrosion preventing and seepage stopping, and the wall materials of the double curvature arch type and the multi-curvature arch type have the functions of corrosion preventing and seepage stopping and also have the function of supporting. Due to the fact that extruding devices are different in power, the width of the machined wall materials can range from 500 mm to 1,200 mm, and the thickness of the machined wall materials can range from 5 mm to 12 mm. The length of the wall materials can be flexibly determined according to the using requirements and the transporting conditions. The wall materials overcome the defects in the prior art, and the purposes of corrosion preventing, seepage stopping and supporting are achieved.

Description

technical field [0001] The invention belongs to the field of anti-seepage and water-stop construction, and relates to a composite super-strong anti-corrosion and anti-seepage wall material and a use method thereof. Background technique [0002] With the rapid development of my country's economy and society, the development and application of underground space in my country is becoming more and more extensive. The depth of vertical anti-seepage and water-stopping for rivers and lakes dams is getting deeper and higher, and the requirements are getting higher and higher. Under this premise, my country's demand for wall materials with high anti-corrosion, anti-seepage and support capabilities and its efficient use methods is becoming more and more urgent. [0003] The materials used in the existing anti-seepage and water-stop construction are mainly commercial concrete, cement soil and steel plate water-stop piles, etc., and there are the following problems: one is that due to t...
