Description
Technical field
Tunnel construction technical field is the utility model is related to, is fixed more particularly, to a kind of tunnel longitudinal drainage blind pipe
Structure.
Background technology
Longitudinal drainage blind pipe is laid in above the side wall ditch bottom of tunnel two, and on the outside of splash guard, design is generally
HDPE107/96 double-walleds punch bellows, and are wrapped up with geotextiles.Longitudinal divisionses length is 8-12 rice, and the curved 135 ° of angles in both ends are round
Along lining cutting surface is transitted to, ditch cable trench accesses lateral sulcus when constructing.
Using C15 non-fine concretes clog closely knit between splash guard and longitudinal drainage blind pipe, be allowed to form displacement hull, really
Protect longitudinal drainage blind pipe drainage effect.Tunnel drainage system construction quality is the key of lining construction, and constructing tunnel
In common common quality defect problem.The construction of longitudinal drainage french drain is particularly critical, in conventional spilled water hole construction, two backings
Draining blind pipe draws section reinforcing not yet in effect afterwards, is hit in concreting process yielding, and it is existing easily to form counter-slope, blocking etc.
As, and aperture is not easy to dig out after the completion of construction.Design drawing reserves longitudinal blind pipe platform in tunnel excavation, but due to platform
Size is 15-30cm, constructional difficulties, and longitudinal french drain platform practice of construction can not excavate shaping.And II grade of country rock design drawing
Longitudinal blind pipe platform is not typically considered, can not solve longitudinal french drain fixation problem.Existing design drawing is typically pressurizeed using rivet
Bar is fixed, and easily splash guard is caused to damage, occur leak the problems such as.
Utility model content
The purpose of this utility model is intended to overcome the shortcomings of the prior art, there is provided one kind is fixed reliable, and draining is blind
The tunnel longitudinal drainage blind pipe fixed structure that pipe is unlikely to deform and ruptured.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of tunnel longitudinal drainage blind pipe fixed structure, it is arranged in the preliminary bracing in tunnel during use；It includes parcel
Draining blind pipe and the geotextiles being bonded with preliminary bracing wall, for hanging draining blind pipe and geotextiles, the suspender belt in J-shaped, if
The splash guard of suspender belt lateral surface is placed in, is filled in the non-fine concrete of draining blind pipe upper end, and two fix suspender belt short side respectively
Upper end and the fixture of suspender belt long side upper end；The fixture includes hot melt packing ring, and is arranged on hot melt packing ring and inserts
Nailing in preliminary bracing；The splash guard and hot melt packing ring hot-melt adhesive paste.
Preferably, the length of the suspender belt expansion is 1m, width 0.12m.
Preferably, the suspender belt is made of plastic cement.
Compared with prior art, the utility model has the following advantages that：
The utility model can utilize splash guard surplus material or leftover pieces and hot melt packing ring, nailing processing system at the construction field (site)
Make, make simply, cost is low.Longitudinal drainage blind pipe plan-position and the longitudinal drainage gradient, practical, function can effectively be controlled
Comprehensively；It can also effectively prevent that splash guard is damaged, and construction positioning is convenient, accurate, improve production efficiency, cost-effective.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is schematic cross-section when the utility model is constructed.
Fig. 2 is the A direction views in Fig. 1.
Fig. 3 is the part B enlarged drawing in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is paid
The every other embodiment obtained, belong to the scope of the utility model protection.
The blind pipe fixed structure of tunnel longitudinal drainage shown in Fig. 1-3, it is arranged in the preliminary bracing 10 in tunnel during use；It is wrapped
Parcel draining blind pipe 5 and the geotextiles 4 being bonded with the wall of preliminary bracing 10 are included, for hanging draining blind pipe 5 and geotextiles 4, in J
The suspender belt 1 of shape, the splash guard 3 of the lateral surface of suspender belt 1 is arranged at, is filled in the non-fine concrete 6 of the upper end of draining blind pipe 5, and two
The fixture 2 of the short side upper end of suspender belt 1 and the long side upper end of suspender belt 1 is fixed respectively；The fixture 2 includes hot melt packing ring, and wears
On hot melt packing ring and the nailing that inserts in preliminary bracing 10；The splash guard 3 and hot melt packing ring hot-melt adhesive paste.
The length that the suspender belt 1 deploys is 1m, width 0.12m, and one is set per 1m along the length direction of draining blind pipe 5.
Combined using the mode of suspender belt 1 and non-fine concrete 6, can effectively fix longitudinal drainage blind pipe, prevent draining blind pipe from floating and sinking.
The remaining material of splash guard 3 can be used to be process for the suspender belt 1, and can be also made of plastic cement.
The utility model can be used for the fixed construction operation of longitudinal drainage blind pipe installation, utilize anchor bar of waterproof plate in tunnels surplus material system
Into suspension suspender belt, weeper drain is fixed by non-fine concrete of constructing, and suspender belt is fixed by heating packing ring, it is ensured that longitudinal direction row
Water blind pipe Arched Bridge Construction Linear and draining longitudinal slope, improve tunnel longitudinal direction blind pipe construction quality.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
