specifically execute mode
A kind of specific embodiment of the present utility model is introduced below by Fig. 1.
As shown in Figure 1, a kind of tunnel slot repair structure of the present utility model, comprise: cavity, the cross section of cavity is trapezoidal, be provided with spring semicanal 1, leak stopping layer 2, waterproof coating 3, grout blanket 4, batten layer 5 and waterproof mortar course 6 in cavity, spring semicanal 1, leak stopping layer 2, waterproof coating 3, grout blanket 4, batten layer 5 and waterproof mortar course 6 are arranged from bottom to up; Also comprise grout pipe 8, the first end of grout pipe 8 is successively through waterproof mortar course 6 and batten layer 5, until grout blanket 4, the second end of grout pipe 8 is positioned at the top of waterproof mortar course 6.
A kind of tunnel slot repair structure of the utility model is the leakage problems that mode that auxiliary, anti-row combines is repaired mountain tunnel and caused due to a variety of causes at running by relying mainly on prevention, to arrange.
Further, the diameter of spring semicanal 1 is 35mm.
Further, the height of cavity is 90mm.
Further, the width of the soffit of cavity is 50mm; The width of the upper surface of cavity is 35mm.
Further, the waterproof coating made for polyurethane sealant of waterproof coating 3.
Further, polyurethane sealant is adopted to seal between grout pipe 8 and batten layer 5.
Technological process of the present utility model:
Step one, surface clean:
Use the high-pressure water jet of bridge tunnel Multifunctional curing machine to clean along crack, by removings such as the spot of fracture faces and putty, expose solid coarse concrete surface;
Step 2, slot or boring:
In left and right, gap, each 25mm place cutting machine cut is the seam of 50 ~ 70mm deeply, or holes every 20 mm, for follow-up fluting is prepared with Churn drill about gap;
Step 3, fluting:
On the basis of step 2, dig out the groove (i.e. cavity) that the degree of depth is 90mm, the cross section of this groove is trapezoidal, and the length on upper base is 35mm, and the length of bottom is 50mm, ensures that external application waterproofing course is greater than 30mm;
Step 4, pipe laying:
Bury one deck φ 35 spring semicanal underground at bottom land, and fix with zinc-iron skin, be connected by φ 35PVC pipe bottom cell wall with between gutter;
Step 5, joint filling are floating:
With extraordinary sealing agent filling bourdon tube periphery, the space of good seal bourdon tube periphery, and floating, should be leak stopping layer; Arrange waterproof coating on leak stopping layer surface, this waterproof coating is the waterproof coating that polyurethane sealant is made;
Step 6, batten layer and Grouting Pipe are set:
Above waterproof coating, arrange batten layer, the first end of Grouting Pipe in batten layer and waterproof coating, adopts polyurethane sealant to seal through batten layer between grout pipe and batten layer.Above batten layer, arrange waterproof mortar course, this this waterproof mortar course is inorganic polymer mortar, plays the effect of fixing Grouting Pipe, and now, the second end of Grouting Pipe is positioned at the top of waterproof mortar course;
Step 7, slip casting:
Carrying out slip casting by the second end of Grouting Pipe between batten layer and waterproof coating, complete and fill out groove work, is grout blanket between batten layer and waterproof coating;
Step 8, observation:
Slip casting every other day, so that the effect of observing after the reparation of crack, the need oozed if any side are done over again, till not seeping water in whole crack.
Step 9, maintenance:
After slip casting, repair rooved face with repairing clay 7, and floating, check and maintenance.
Above-described embodiment is only for illustration of technological thought of the present utility model and feature, its object is to enable those skilled in the art understand content of the present utility model and implement according to this, only can not limit patent model of the present utility model employing with the present embodiment to enclose, namely the equal change done of all spirit disclosed according to the utility model or modification, still drop in the scope of the claims of the present utility model.
