Embodiment Construction

[0020] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0021] An improved tunnel waterproof hot-melt gasket, see attached figure 1 and 2 , including a hot-melt gasket body 1, a circular groove 1-1 and a central through hole 1-2 are arranged on the hot-melt gasket body, wherein the circular groove is used for metal gasket installation, and the central through hole is used for steel nails to penetrate overused.

[0022] The innovative point of this technical solution is: it also includes the puncture-proof pad 2 . The anti-puncture gasket is made of the same material as the hot-melt gasket body, and the anti-puncture gasket is a flat gasket structure, which is formed by the gasket body part 2-1 and the body of the hot-melt gasket. The outer connection part 2-2 is formed, and a connection hole is...

Abstract

The invention discloses an improved tunnel waterproof and drainage hot-melt gasket and a fixing construction method. The hot-melt gasket comprises a hot-melt gasket body and further comprises a piercing-preventing spacer. The piercing-preventing spacer is of a plane spacer structure constituted by a spacer body part and an outer connecting part provided with a connecting hole. The piercing-preventing spacer is riveted to the hot-melt gasket body through a rivet piece installed in the connecting hole in a penetrating mode in a position-adjustable mode. When in the first working position, the piercing-preventing spacer and a circular groove in the hot-melt gasket body are in a completely-staggered state, and when the piercing-preventing spacer is in the second working position, the spacer body part is located on the outer side opposite to a central though hole to enable the central through hole to be covered completely. The fixing construction method comprises the steps that S1, the piercing-preventing spacer is rotationally adjusted to the first working position; S2, the hot-melt gasket is fixed to a primary supporting face through a metal gasket and a steel nail; S3, the piercing-preventing spacer is rotationally adjusted to the second working position; and S4, quality acceptance is conducted. According to the improved tunnel hot-melt gasket, piercing of a waterproof plate can be effectively avoided.

Description

technical field [0001] The invention belongs to the waterproof structure of railway tunnels, in particular to an improved tunnel waterproof and drainage hot-melt gasket and a fixing construction method for the hot-melt gasket. Background technique [0002] The construction of hot-melt gaskets is an important part of the construction process of railway tunnel waterproofing and drainage. The existing hot-melt gasket has a circular gasket structure, and a circular groove is arranged at the outer middle of the hot-melt gasket, and a central through hole is arranged at the center of the circular groove. The existing hot-melt washer is fixed on the primary support surface through the metal washer arranged in the circular groove and the steel nail passing through the central through hole. [0003] The hot-melt gasket adopts the above-mentioned structure and installation method. In actual operation, when the operator cannot strictly follow the construction operation specifications,...
