Embodiment Construction

[0054] 1. Preparation before construction:

[0055] (1) Drainage grooves in the cave;

[0056] Double-side drainage ditch and central rectangular ditch are adopted. The side ditch is mainly used to collect groundwater and communicate with the central rectangular cover ditch through the φ100mm PVC horizontal drainage pipe, so that the water in the cave can be discharged to the outside of the cave through the central rectangular cover ditch, and horizontal drainage The longitudinal spacing of the pipes is 30m, and the longitudinal slope of the ditch is consistent with the slope of the line;

[0057] (2), geotextile laying;

[0058] The long side of the geotextile (weight not less than 350g / m2) is laid along the ring direction of the tunnel, and the laying length is greater than 150cm outside the concrete circulation pouring length; The gasket is fixed on the concrete base surface, and the center line of the geotextile is required to coincide with the center line of the tunnel....

Abstract

The invention discloses a tunnel lining construction method used in the tunnel construction process. The tunnel lining construction method mainly solves the problems that an existing tunnel lining construction method is poor in engineering quality and low in work efficiency. The tunnel lining construction method comprises the steps that preparation before construction is conducted, specifically, in-hole drainage groove building, geotextile cloth laying, waterproof plate laying, drainage blind pipe mounting are conducted, and waterproof treatment is conducted on construction joints and deformation joints; and lining construction is conducted, specifically, firstly, inverted arch construction and inverted arch filling construction are conducted, then secondary lining is conducted, construction is conducted by using an integral hydraulic lining trolley, rebar bonding is conducted, concrete pouring is conducted, vibration is conducted by using an inserted-type vibration rod, then formworksare dismantled, and maintenance is conducted. The tunnel lining construction method has the advantage of solving the problems of poor engineering quality and low working efficiency generally existedin current construction.

Description

Technical field: [0001] The invention relates to a tunnel lining construction method in the tunnel construction process. Background technique: [0002] Lining refers to a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the deformation or collapse of the surrounding rock. [0003] Although the existing tunnel lining construction methods can ensure construction safety, there are common problems in the construction such as the overall sinking of the vault, poor engineering quality, low work efficiency, high construction cost, and long construction period. Invention content: [0004] The technical problem to be solved by the present invention is to provide a tunnel lining construction method with good construction quality, low cost and short period. [0005] The above purpose is achieved in this way: [0006] 1. Preparation before construction: [0007] (1) Drainage grooves in the cave...
