Problems solved by technology

[0005] However, the inventors found that some existing soil curing agents have at least the following problems in the course of actual tests: (1) directly as base strength is not high enough; (2) compatibility is not high enough; (3) water repellency is not enough it is good
The existence of these problems will significantly affect the solidification performance of the soil

Abstract

The invention belongs to the technical field of a soil curing agent, and particularly relates to a TRD continuous wall curing agent. The curing agent is prepared from the following ingredients including 15 to 55 parts of sodium dodecyl polyoxyethylene ether sulfate, 20 to 30 parts of sulfonated oil, 2 to 8 parts of polyanionic cellulose, 10 to 50 parts of polyhydric alcohols, 10 to 20 parts of high-molecular polymer anionic surfactants, 10 to 20 parts of water, 15 to 30 parts of fly ash, 5 to 20 parts of water glass, 3 to 9 parts of sodium silicofluoride, 10 to 40 parts of cement, 10 to 20 parts of phosphogypsum, 2 to 6 parts of sulfuric acid, 5 to 20 parts of polyacrylamide, 10 to 15 parts of epoxy resin and 3 to 5 parts of hydramine. The curing agent has the advantages of high pressure-resistant intensity and excellent waterproof and dampproof performance; waste soil, slag soil and building waste soil can be effectively modified to be reused as road building materials; the soil curing time is prolonged; the pressure-resistant intensity is improved, so that the TRD continuous wall construction work period is shortened; the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of soil curing agents, in particular to a curing agent suitable for TRD continuous walls. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] The TRD construction method, that is, the construction method of the mixing wall type underground diaphragm wall, is to insert a cutting box with a cutting chain and a cutter head that meets the design depth into the ground, and inject cement slurry into the foundation while cutting longitudinally and horizontally to form grooves. It is a construction technique that has been fully mixed with the original foundation to form a continuous wall of equal thickn...
