A kind of epoxy grout glue for sound barrier column bonding and its preparation method and construction technology

Abstract

The invention provides an epoxy grouting glue for bonding a sound barrier stand column and a preparing method and construction technology of the epoxy grouting glue. The epoxy grouting glue for bonding the sound barrier stand column is prepared from, by weight, 5-10 parts of epoxy resin, 2.5-9 parts of diluent, 2.7-7.8 parts of curing agent, and 80-120 parts of aggregate. The epoxy grouting glue is flexible and adjustable in operating time, early and high in strength, high in bonding strength, good in pourability, good in anti-seepage performance, namely leaking stoppage performance, good in tenacity, slight in expansion, and low in cost, and saving energy and protecting the environment. According to the epoxy grouting glue for bonding the sound barrier stand column and the preparing method and construction technology of the epoxy grouting glue, the preparing method is simple, the prepared epoxy grouting glue is good in performance, and the performance of the epoxy grouting glue meets the requirement of the sound barrier stand column when the glue conducts grouting at the high altitude. The construction technology of the epoxy grouting glue for bonding the sound barrier stand column is simple, and the durability of the whole stand column can be improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an epoxy grouting glue for bonding sound barrier columns, a preparation method and a construction process thereof. Background technique [0002] The sound barrier column of this application is a layered assembled column, such as figure 2 As shown, the sound barrier column includes a first barrier column 400 and a second barrier column 500, and the first barrier column 400 and the second barrier column 500 are fixed by bolts. [0003] There is a cavity 300 between the first barrier column 400 and the second barrier column 500. In order to ensure the safety and durability of the sound barrier column, the cavity in the middle of the column must be filled with a potting material, and it should have a certain adhesive force. Bond each column piece into a solid whole. [0004] Existing pouring materials, such as epoxy resin pouring glue, epoxy resin grouting ma...

AI Technical Summary

Problems solved by technology

[0007] (2) serious leakage

The glue will seep out along the fiber, along the thread opening between the screw and the nut and all other tiny pores, which not only wastes the pouring material, but also pollutes the surface of the column, and the glue level in the cavity gradually decreases due to leakage. It also affects the perfusion and bonding effect

[0008] (3) The price is high and the cost of use is high

[0012] (1) Low adhesion

[0013] (2) The hardening speed is slow, it is difficult to solve the contradiction between the operability time and the early strength, and the quality fluctuates greatly

[0014] (3) Low flexural strength and high brittleness

When the train travels at high speed and generates wind pressure and vibration, it is prone to brittle cracking
