Problems solved by technology

Among them, the shield tunneling method is suitable for medium-soft soil layers and interval tunnels with large buried depths. Shield segments are used for support, which has defects such as high cost, long preparation time, and shield wells affecting road traffic.
The shallow buried excavation method uses steel grids, shotcrete, and molded concrete to form a support system. Reinforced concrete needs to be cast underground, which has defects such as long construction period, poor working environment, many safety risks, and difficult quality assurance.

Embodiment Construction

[0029] In order to clearly illustrate the technical features of this solution, the specific implementation of the present invention will be further described below based on the drawings.

[0030] A method for installing an underground arched roof includes the following steps:

[0031] a: Set up a pipe shed 5 in the soil for advanced support (such as figure 1 , figure 2 As shown), and then drill a groove 2 under the pipe shed 5 to the design depth (such as image 3 , Figure 4 Shown);

[0032] b: Insert the two longitudinal beams 6 into the groove 2 so that the two longitudinal beams 6 are overlapped on the concrete precast piles 3 on both sides of the tunnel. The concrete precast piles 3 are provided with corbels 4, and the longitudinal beams Beam 6 overlapped on the corbel 4 (such as Figure 5 , Image 6 Shown);

[0033] c: Insert the prefabricated arched top plates 1 into the grooves 2 one by one, so that the two sides of the prefabricated arched top plate 1 are overlapped on the l...

Abstract

The invention relates to the technical field of construction engineering, in particular to an underground arch top plate mounting method. The method mainly comprises the steps that a pipe roof is driven into soil for forepoling, a groove is drilled, longitudinal beams are mounted, and a prefabricated arch top plate is mounted. By means of the underground arch top plate mounting method, the quality is reliable, cost is low, the effects of environment protection and energy conservation are achieved, construction is easy and safe, the construction period is short, and the waterproof effect is good.

Description

Technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a method for installing an underground arched roof. Background technique [0002] Currently, the construction methods of tunnels in the interval mainly include shield tunneling or shallow tunneling. Among them, the shield method is suitable for medium-soft soil layers and interval tunnels with a large buried depth. The shield segment is used for support, which has the disadvantages of high cost, long preparation time, and shield wells affecting road traffic. The shallow burying method uses steel grids, sprayed concrete, and molded concrete to form a supporting system, and requires cast-in-situ reinforced concrete underground, which has disadvantages such as long construction period, poor working environment, multiple safety risks, and difficult quality assurance. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings of...
