Tunnel waterproof layer sling type waterproof plate construction method

Abstract

The invention discloses a tunnel waterproof layer sling type waterproof plate construction method. The method comprises the following steps of S4, paving and hanging a waterproof plate, gradually unfolding a waterproof roll, attaching to the surface of a primary support to support the waterproof roll, marking when a sling on a non-woven fabric is attached to the surface of the primary support, drilling a hole with the depth of about 100 mm at the marked part by using an electric drill, nailing a small wood pile with a fine lead wire, and cutting off the part higher than the surface of the primary support. The invention relates to the technical field of tunnel waterproof plate construction. According to the tunnel waterproof layer sling type waterproof plate construction method, after primary supporting, early strength concrete spraying, primary supporting surface back break and sharp object treatment of a tunnel are carried out, standard lines are drawn through accurate lofting, the size of each ring of the waterproof plate is determined, the EVA sling type waterproof plate with the thickness of 1.2 mm is adopted for laying construction, through-nail-free construction suspension type row hanging can be completed at a time, the construction difficulty of a traditional waterproof material in a tunnel can be greatly lowered, the laying quality and laying efficiency are improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of tunnel waterproof board construction, in particular to a construction method of a suspender-type waterproof board for a tunnel waterproof layer. Background technique [0002] my country's transportation lines are rapidly expanding, and tunnel construction has also been rapidly developed. Whether it is in railways, highways or urban traffic, tunnels are playing an increasingly important role, which promotes the rapid development of my country's transportation industry. , Bring convenience to our driving. However, due to various reasons such as technology and management, the tunnel is facing various threats during construction, and these threats also directly affect the operation status of the tunnel. As one of the hazards of tunnels, water leakage is closely related to our life and directly threatens the safety of driving. Especially in the tunnel lining, waterproof board construction is the key to achiev...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a construction method of the tunnel waterproof layer sling-type waterproof board, which solves the existing construction method of the tunnel waterproof board. The waterproof board is easy to be pierced by sharp objects during construction, and the whole cycle of waterproofing and secondary lining The construction speed is relatively slow, and improper laying of waterproof boards is likely to cause damage and lead to repair problems
