Embodiment Construction
[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0046] Such as figure 1 , 2 As shown in , 3, a tunnel primary lining structure, which is formed by arranging and splicing multiple groups of prefabricated parts 1 in a certain order in the soil body; adjacent prefabricated parts 1 are connected and fixed by locks, slots, buckles or bolts ;
[0047] The shape of the primary lining structure is circular, semicircular, saddle or arched;
[0048] The material of the prefabricated part 1 is a corrugated steel plate (...

The invention discloses a novel tunnel first lining structure and a construction method thereof. The novel tunnel first lining structure is formed by splicing a plurality of groups of prefabricated members. The prefabricated members are put one by one around a tunnel to be build and spliced to form the novel tunnel first lining structure, through special construction equipment before tunnel excavation; the novel tunnel first lining structure is used for replacing a first support or all lining structure in the traditional tunnel constructions. The construction method includes the steps of site preparation, mounting and debugging of construction equipment, assembly of box members, in-position installation of the box members and equipment, driving and earth discharging, box driving, placement and assembly of the prefabricated members, and the like. The construction method using lining prior to excavation ensures tunnel construction is safe and universal; by replacing cast-in-place concrete with the prefabricated members, and the problems with shotcrete quality and progress caused by casting in place the cement in traditional structural construction of a first lining or second lining are solved; the construction method with simple steps is easy to implement, materials are easy to carry and place, and factory construction of the tunnel is facilitated.
Description
technical field [0001] The invention relates to the field of tunnel construction, in particular to a construction method for a primary lining structure of a tunnel. Background technique [0002] The initial lining of the tunnel is the initial support. It is a structural layer with a small rigidity immediately after the excavation of the tunnel and is a part of the permanent load-bearing structure. It is generally composed of anchor rods, shotcrete, steel frames, steel mesh, etc. and their combinations. . Concrete spraying or concrete pouring process will be involved in the construction process of the primary lining and the secondary lining, and there are phenomena such as uneven pouring of the cast-in-place concrete, which will lead to uneven and incomplete structures of the primary lining or the secondary lining. In addition, the existing primary lining construction is carried out after tunnel excavation. If the primary support can be completed before excavation, the tunne...
