Description
Technical Field
The utility model relates to the field of roadway construction, in particular to a buckle type sealing geocell for roadway support.
Background
Because the influence of surrounding rock dead weight stress and ground stress after the tunnel excavation, the surrounding rock internal stress can be along with the effect of external stress and redistribute, the inside existence that has inhomogeneous stress of surrounding rock in this in-process tunnel, and the unbalanced degree of surrounding rock stress can be bigger when meetting unfavorable geological conditions such as fault, broken area, if not in time carry out anchor net to the surrounding rock and strut, can cause the unbalanced distribution of surrounding rock stress and then lead to the unstable destruction of surrounding rock.
In the work progress, the inner wall in tunnel often rubble and infiltration fall down, influences the construction, and prior art adopts the anchor net to strut, though can support its inner wall, but its infiltration problem can't be solved, reduces the efficiency of construction. According to construction experience, the geocell is feasible to be used for waterproofing and supporting, but the length of the geocell is smaller than that of a roadway and needs to be prolonged, the body of the geocell is easy to damage due to the direct welding of the interfaces, the strength of the geocell body is reduced, and the geocell body is easy to peel off.
SUMMERY OF THE UTILITY MODEL
In order to solve the above-mentioned drawbacks of the prior art, the present invention provides a snap-in sealing geocell for roadway support.
The purpose of the utility model can be realized by the following technical scheme:
a buckle type sealing geocell for roadway support comprises a bending portion and a vertical portion, wherein the bending portion and the vertical portion are made of the same material, steel wires are embedded in the bending portion and the vertical portion, a plurality of groups of limiting parts are arranged on the inner side wall, close to two ends, of the bending portion, each limiting part comprises two limiting strips arranged in parallel, and a limiting groove is formed between the limiting strips;
the vertical portion is arranged on the inner side of the bending portion, a plurality of groups of limiting rods are arranged on the outer wall, close to the top end, of the vertical portion, and the limiting rods are clamped in the limiting grooves and are welded with the limiting rods in a hot melting mode.
Furthermore, the bending part and the vertical part are made of one of PP, PE and PET.
Further, the embedding direction of the steel wire is consistent with the length direction of the bending part and the vertical part.
Further, the transverse distance between the limiting rods is 10-15 cm.
The utility model has the beneficial effects that:
when the water baffle is used, the bending part and the vertical part are respectively attached to the inner wall of the roadway, then the protective film is torn, the limiting rod is clamped in the limiting groove and is in hot-melt welding with the limiting strip, and the bending part and the vertical part integrally play the role of the water baffle.
The outer surface at spacing and the surface of gag lever post all the cladding have the protection film, and the protection film tears the back, welds the block again, has improved cleanliness and welding strength, and can not destroy the body.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The utility model provides a buckle formula sealed geotechnological check room for tunnel is strutted, as shown in fig. 1-4, geotechnological check room is used for the tunnel to strut, including flexion 1 and vertical portion 2, the material of flexion 1 and vertical portion 2 is the same, chooses for use one of PP, PE, PET, and peel strength is high.
The steel wire 3 is embedded in the bending part 1 and the vertical part 2, and the embedding direction of the steel wire 3 is consistent with the length direction of the bending part 1 and the vertical part 2.
The inner side walls, close to the two ends, of the bending portion 1 are provided with multiple groups of limiting parts, each limiting part comprises two limiting strips 11 arranged in parallel, a limiting groove 12 is formed between the limiting strips 11, the vertical portion 2 is arranged on the inner side of the bending portion 1, multiple groups of limiting rods 21 are arranged on the outer wall, close to the top end, of the vertical portion 2, the transverse distance between the limiting rods 21 is 10-15cm, the limiting rods 21 are clamped in the limiting grooves 12, and the limiting rods 21 and the limiting strips 11 are welded in a hot melting mode.
