Fig. 2 is splicing seams side wall waterproof construction figure.

Specific implementation mode

The utility model is further described below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1 and Fig. 2, a kind of piping lane splicing seams grouting structure, including be arranged by piping lane socket 1 and piping lane bellmouth 2 The prior art may be used in internal layer waterproof layer in the splicing seams of composition and waterproof outer layer, internal layer waterproof layer and waterproof outer layer In for piping lane splicing seams sealing common waterproof layer.In the present embodiment, waterproof outer layer is by two-component polysulfide sealant layer 3 It is formed with outer layer polyethylene cystosepiment 4；Wherein, two-component polysulfide sealant layer 4 is close to the outside of splicing seams.Internal layer waterproof layer by Water-swellable cushion rubber 5, inner layer polyethylene cystosepiment 6 and inorganic leak-stopping material layer 7 are constituted.Wherein, inorganic water-proof leak stopping material The bed of material 7 is located at inorganic leak-stopping material layer 7 and water-swellable cushion rubber 5 close to the inside of splicing seams, inner layer polyethylene cystosepiment 6 Between.Grouting room 8 is formed between internal layer waterproof layer, waterproof outer floor and splicing seams, in the left and right sides wall of internal layer waterproof layer Middle position is sealed equipped with about the one group grouting pipe 9 that is intervally arranged, and grouting pipe 9 sequentially passes through inorganic water-proof leak stopping material The bed of material 7, inner layer polyethylene cystosepiment 6, water-swellable cushion rubber 5 are connected to grouting room 8.In the two side up and down of internal layer waterproof layer Between sealing is equipped with two upper return pipes 10 respectively at position and lower return pipe 11, upper return pipe 10 and lower return pipe 11 sequentially pass through Inorganic leak-stopping material floor 7, inner layer polyethylene cystosepiment 6, water-swellable cushion rubber 5 are connected to grouting room 8.

For the utility model piping lane splicing seams grouting structure, as further setting, in the side wall of internal layer waterproof layer Surrounding is additionally provided with the slip casting detection pipe 12 being connected to grouting room 8.The filling situation that slurries are observed by slip casting detection pipe 12, works as note When starching 12 grout of detection pipe, by block and can continue to fill up slip casting detection pipe 12.In the present embodiment, grouting pipe 9 It stretches out the outer one end of splicing seams and is equipped with the silk mouth docked with external slip casting machine, can make slurries quickly by grouting pipe 9 Capillary channel penetrates into splicing seams, and ensures that splicing seams slip casting is closely knit full by return pipe pulp.

For the utility model piping lane splicing seams grouting structure, as further setting, grouting pipe 9 is by inner core of spring Non-woven filter cloth layer and nylon yarn the stratum reticulare composition being wrapped in successively outside inner core of spring.Capillary channel is formed in inner core of spring. Grouting pipe 9 using the above structure not only has crushing resistance, while grouting pipe has certain flexibility again, is not easy splicing It is crushed when tensioning；It can be fitted around in splicing seams according to piping lane difference size, chamfering position is without blocking, flexible angulation Degree.

For this practicality piping lane splicing seams grouting structure, as further setting, the top and bottom sidewall of grouting room 8 is equipped with Zigzag or netted saw kerf.

The slip casting process of the utility model is：

Grouting pipe (grout) on grouting pipe (note) → lower return pipe 11 (grout) → left and right sides under the left and right sides；It is left Grouting pipe (note) → slip casting checks that pipe 12 (grout) → upper 10 (grout) → slip casting machine pressure gauge of return pipe reaches on right both sides 3bar (stops slip casting).Grouting Pipe grout illustrates that piping lane splicing seams lower half portion fills slurries on the left and right sides, and upper return pipe emits Slurry illustrates that piping lane splicing seams top half will fill slurries, and slip casting machine pressure gauge reaches 3bar and illustrates that piping lane splicing seams are complete Fill slurries (elastic polyurethane seals slurries 13).

Above-mentioned implementation is injected slurries by grouting pipe 9 according to above-mentioned grouting process using spring grouting pipe slip casting Into prefabricated piping lane splicing seams.During slip casting, grouting quality is controlled in strict accordance with " grouting process quality control process ", it can Accomplish the complete full of splicing seams inside slurry.Using this grouting device, the leakproofness that prefabricated piping lane connects splicing seams obtains effectively It ensures, can preferably prevent percolating water phenomenon, be widely portable to the construction of the Grouting engineerings such as deformation joint, construction joint.

Instantly return pipe 11 cannot timely grout when, illustrate that there may be running pulp phenomenons for piping lane splicing seams lower half portion, preferably Suspend slip casting, interval 2-3 hours (slurries are in paste) continues slip casting afterwards；When slip casting check pipe 12 cannot timely grout when, explanation There may be running pulp phenomenons for piping lane splicing seams top half, preferably suspend slip casting, interval continues to note for 2-3 hours after (slurries are in paste) Slurry.

Above-described embodiment is only to clearly demonstrate the utility model example, rather than the restriction to embodiment. For those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description Or it changes.Here without can not be also exhaustive to all embodiments.And the obvious variation thus amplified out Or among changing still in the scope of protection of the utility model.
