隧道漏水不但会使有关砌体日益损坏,影响线路的运行条件,而且随着祖国铁路事业中电气化程度的不断提高,消除隧道漏害,保证用电安全,就显得格外重要。针对处理峒內漏水问題,我们经过几个月的模索,采用几种方法,本文仅对采用天津防水剂厂出产的硅酸钠防水剂在隧道內的使用情况和一些试验数据谈谈粗浅的体会。一、硅酸钠防水剂的特性 1. 硅酸钠防水剂(以下简称防水剂)是一种新产品,它的主要成份为硫酸铝鉀,硫酸铜,硫酸亚铁,重鉻酸鉀,硅酸钠和水制成的
Leakage of the tunnel will not only increase the damage of the relevant masonry and affect the operating conditions of the line. With the continuous improvement of the electrification degree in the railway undertaking of the motherland, the elimination of tunnel leakage hazards and the guarantee of electricity safety are particularly important. In order to deal with the problem of water leakage in the bowl, we used several methods to simulate the leakage of water in the bowl. This article only talked about the use of sodium silicate waterproofing agent produced by the Tianjin Water Repellent Plant in the tunnel and some experimental data to talk about the shallow experience. . First, the characteristics of sodium silicate waterproofing agent 1. Sodium silicate waterproofing agent (hereinafter referred to as water repellent) is a new product, its main components are aluminum potassium sulfate, copper sulfate, ferrous sulfate, potassium dichromate, silicon Made of sodium and water
