Problems solved by technology

[0002] Mine method tunnel waterproofing is set between the primary support and the secondary primary building. Generally, plastic waterproof boards (EVA, ECB, PVC) + non-woven fabrics (mainly protecting waterproof membranes) are used for waterproofing. In the existing Under certain construction conditions and organizational forms, the plastic waterproof board is not bonded to the subsequent poured second-lined concrete structure at all, and it is easy to channel water. In addition, the inevitable defects of the waterproof board (lap joint leakage, damage) will cause the waterproof board and the A large area of ​​water is stored between the two lining concretes, resulting in the loss of the overall waterproof effect
According to actual feedback, tunnel leakage is very common across the country, and even leakage seriously affects the driving safety and structural life in the tunnel, and brings a heavy burden to later maintenance

Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0020] The invention provides a method for waterproofing mine tunnels, in which a self-adhesive waterproof board is laid between the primary support and the secondary primary laying;

[0021] The self-adhesive waterproof board is composed of a transparent substrate, a polymer self-adhesive film and a cladding material, wherein the polymer self-adhesive film is bonded to the post-cast concrete;

[0022] The transparent substrate comprises: 5-30 parts by weight polyethylene, 5-30 parts by weight polypropylene, 20-50 parts by weight ethylene-propylene copolymer, and 20-50 parts by weight ethylene-octene copolymer; the transparent The substrate is made by blen...

Abstract

The invention discloses a waterproof method of a mining method tunnel. A self-adhesive waterproof plate is laid between primary supporting and secondary lining; and the self-adhesive waterproof plateis composed of a transparent base material, a high-molecular self-adhesive film and a facing material, wherein the high-molecular self-adhesive film is bonded with post-cast concrete. The self-adhesive waterproof plate can be firmly bonded with a subsequently-cast secondary-lining concrete structure, and the bonding peel strength is 2.0 N / mm or more, and a water-channeling channel can be effectively eliminated. Even through a weak point appears in the waterproof layer in the later period, water can also be locked at this point, leakage is not easy, and the water is prevented from moving aroundbetween the waterproof layer and the secondary-lining concrete.
