Example Embodiment

[0010] Such as figure 1 , figure 2 As shown, the construction steps of the present invention are as follows:

[0011] 1. Install side wall top arch reinforcement

[0012] Utilize the slab gravel road 6 that has been formed during excavation, install side wall top arch reinforcement 1 in sections. Small tunnel diameters can be directly used to install steel bars on gravel roads; for large tunnel diameters, steel bars can be installed on the gravel roads by setting up a small openable operating platform. The side wall top arch reinforcement is not affected by the bottom slag removal, and can be staggered with the bottom slag removal at the same time, or the top arch side wall reinforcement 1 can be installed at the same time on multiple working surfaces;

[0013] When installing the side wall top arch reinforcement, because the reinforcement has no bottom support, it is necessary to perforate and bury the bottom support of the side wall reinforcement according to the actual situati...

Abstract

The invention provides a high-speed construction method of tunnel lining concrete. The method comprises the following steps: mounting umbrella arch reinforcement bars of the side wall first; removing ballast of tunnel soleplates; mounting reinforcement bars of the tunnel soleplates; pouring concrete of the tunnel soleplates; and pouring umbrella arch concrete of the side wall or pouring gross section concrete. The method has the advantages of improving the utilization ratio of the ballast road paved before excavating, reducing the working faces formed by repeatedly backfilling and removing the ballast road, overcoming the defects of repeatedly removing the ballast and paving a construction road, ensuring the simultaneous concrete construction of a plurality of working faces for the same tunnel lining, speeding up the construction of tunnel lining concrete and saving construction cost.

Description

technical field [0001] The invention relates to a tunnel lining concrete construction method, in particular to a tunnel full-section lining concrete rapid construction method. Background technique [0002] At present, in the construction of tunnel full-section lining concrete, the floor concrete is generally poured first, and then the side walls and top arch concrete are poured. Clearing the tunnel floor gravel material before pouring the bottom slab concrete takes a long straight-line construction period; in addition, in order to facilitate the construction and transportation of the side wall and top arch concrete lining in the later stage, the construction lane is reserved when the tunnel bottom slab concrete is poured or the lined bottom slab concrete is laid The driveway is set with asphalt sand and gravel; the temporary driveway reserved for the floor or formed by laying on the concrete floor needs to be removed later. The clearing of temporary lanes and the setting of...
