Distribution, to protect the lower part of colluvial clay T0.
It can be by the design to 20 structure of guide pipe, to facilitate the face and connector of foregoing grouting port K2 in the present embodiment
40 formation.For example, in a kind of specific implementation method in the aforementioned embodiment, guide pipe 20 have expose to be oriented to wall 10 it
Outer revealed section 21, revealed section 21 are located at the positioning region 22 of the same busbar of guide pipe 20 with corresponding grouting port K2,
It is used to indicate the position of grouting port K2.By setting positioning region 22 in revealed section 21, it can facilitate and be adjusted when being inserted into guide pipe 20
The position of the grouting port K2 of each guide pipe 20.In actual use, the positioning region 22 that can make two adjacent guide pipes 20 is mutual
Face, so as to make corresponding grouting port K2 facing each other so that the distance between grouting port K2 is most short, corresponding support body
The connector 40 that 30a can easily be connected to form one.Optionally, guide pipe 20 has from the edge of its grouting port K2 along string
To two guide edges 23 to be formed that bend inwards, big outer small splay grouting port K2 in the common restriction of two guide edges 23.
During interior big outer small splay grouting port K2 causes slip casting, slurry is subject to larger extrusion pressure in the port of export, can
Support body 30a contacts is fast and effeciently made to be fused into connector 40.Optionally, one end of guide pipe 20 is taper, is oriented to reducing
Resistance during 20 injection of pipe.
In conclusion the colluvial clay tunneltron booth structure 100 in the utility model embodiment is consolidated in by one end and led
To wall 10, the other end is inserted into colluvial clay T0 and passes through priming charge slurry liquid and hardens in the adjacent guide pipe 20 of the connection to be formed
The similary main body 30 being made of cement grout connector 40, a netted bearing bed of arch can be formed, have carrying
The strong advantageous effect of ability can realize effective carrying to top colluvial clay T0, avoid collapsing slope during tunnel excavation
Product body T0, which caves in, to be influenced to construct or occur accident.
