Outstanding effect of the present utility model is:
Compared with prior art, the utility model is simple to operate, and leak stopping is convenient, and it can make the gap between the section of jurisdiction in underground construction carry out waterproofing and leakage-stopping, guarantees the water proofing property of underground construction.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model moulding groove;
Fig. 3 is the structural representation that the utility model does not pour into slip casting liquid layer.
The specific embodiment:
Embodiment, see shown in Fig. 1 to Fig. 2, a kind of underground project waterproof leak stopping structure, comprise two adjacent sections of jurisdiction 10, between the adjacent side wall upper part of described two adjacent sections of jurisdiction 10, form groove 1, between the adjacent lower sidewall of two adjacent sections of jurisdiction 10, form gap 2, gap 2 communicates with groove 1, it is below groove 1;
In described gap 2, by enhancing perfusion, there is slip casting liquid layer 3, in groove 1, be filled with joint seal material layer 4 and caulking material layer 5, the upper end face of slip casting liquid layer 3 contacts with the bottom surface of joint seal material layer 4, the end face of joint seal material layer 4 contacts with the bottom surface of caulking material layer 5, on the adjacent part of the upper end face of caulking material layer 5 and the inside wall 11 of its section of jurisdiction, both sides 10, all scribbles float coat 7.
The adjacent part of the upper end face of described caulking material layer 4 and the inside wall 11 of its section of jurisdiction, both sides 10 maintains an equal level.
Described slip casting liquid layer 3 is solidified and is formed by soluble polyurethane slurries.
Described joint seal material layer 4 is solidified and is formed by double-quick cement.
Described caulking material layer 5 is epoxy tar coating.
The upper end face of described slip casting liquid layer 3 is arcwall face, and the bottom surface of joint seal material layer 4 is arc-shaped concave.
See shown in Fig. 1 to 3, its operational sequence comprises: hacking, cutting, tick slot; Take out pipe, filleting, wipe one's face, slip casting.
1, dabbing, slot, tick slot dabbing; At two adjacent section of jurisdiction 10 seam two upper lateral parts, respectively cut a hole wide 20cm, manually use chip-axe dabbing, expose fresh concrete basal plane and make it coarse, for enhancing rigidity, wipe one's face and lay the first stone with concrete bonds well.Then carry out slot, tick slot; With the cutting of diamond saw blade concrete cutting machine, cutting width 4～5cm, ditch depth 5～6cm, then uses electric impact drill tick slot, finally with power shovel, becomes with artificial refine the groove 1 that 5～6cm is dark.
Then take out pipe operation, adopt φ 14mmPVC sebific duct to be placed on the bottom of groove 1, double-quick cement or other fast setting cement pressure pipe joint seals form joint seal material layer 4, then take out pipe operation, sebific duct is extracted out from one end of groove 1, and the other end stays a diversion Grouting Pipe 20.
After wherein taking out pipe, just make the bottom surface of joint seal material layer 4 be shaped to arc-shaped concave, while facilitating follow-up perfusion injection slurry, conveniently, perfusion thoroughly in circulation.
2, then carry out filleting, caulking material can be selected: (1) upper tunnel board 851 tar polyurethane coating; (2) TPU polyurethane bicomponent sealing amine; (3) TPU polyurethane sealing putty; (4) 888 swell soil polyurethane sealants; (5) coal-tar epoxy caulking material.First with wire brush and hairbrush, clean out floating ash, the earth of groove 1 and both sides, then embed seam material (being undertaken by the construction technology of various caulking materials in construction), after requirement pointing, be repeatedly squeezed to closely knit, the most handy scraper or manually press twice in caulking material solidification process, so that bonding is better, finally form caulking material layer 5.
3, finally wipe one's face, can adopt neoprene polymer mortar to wipe one's face and form float coat 7.The waterproof of wiping one's face also can be implemented by the five layers of waterproofing process of wiping one's face.After having wiped one's face, take water seasoning 3～4 days.
4, first slip casting use hand-lift type grouting pump to diversion Grouting Pipe 20 setting-out, and then pressure injection soluble polyurethane slurries (or other chemical grouting materials).After slurries solidify, form slip casting liquid layer 3, with pocket knife, slice off pre-buried diversion Grouting Pipe 20, then seal with double-quick cement.
This is simple in structure, and leak stopping is convenient, and it can make the gap between the section of jurisdiction in underground construction carry out waterproofing and leakage-stopping, guarantees the water proofing property of underground construction.
