Abstract
The utility model discloses an underground continuous wall joint grouting device and relates to a steel pipe. An underground continuous wall comprises a steel reinforcement cage and an I-shaped water retaining steel plate connected at the joint position of the steel reinforcement cage. The device comprises two steel pipes which are welded to the junction position of a flange plate and a web plate of the I-shaped water retaining steel plate respectively, a plurality of grout discharging holes are arranged on each steel pipe at intervals, and rubber sleeves for tight protection are sleeved on the steel pipes. The underground continuous wall joint grouting device can enable concrete pouring of the underground continuous wall to be finished, can instantly and downward place grouting core pipes through the steel pipes and quickly perform grouting of the steel pipes when the joint positions are defective in quality and are required to be grouted before earth excavation or in the earth excavation process, decreases working procedures of carrying a hole guiding device, guiding holes again and downward placing grouting pipes, saves the work preparation time for joint grouting and ensures the construction safety.
Description
Technical field
The utility model refers in particular to a kind of underground continuous wall connector grouting device about a kind of steel pipe.
Background technology
When ground-connecting-wall was constructed, the joint quality defective was emphasis, the difficult point of control always, joint produces that concrete streams, joint concrete slag inclusion, terminal bruss wall not thoroughly, the joint discontinuity produces strain cracking etc. all makes joint have the certain quality defective.When joint mass defect occurred and needs slip casting to handle in the past, the general installation drawn drilling machine and drawn the hole immediately, and transfers Grouting Pipe and carry out slip casting.When the geology complicated condition, or the ground-connecting-wall joint exists and to cave in, and when a large amount of concrete obstacle was arranged, quality, the speed of drawing the hole were all had a strong impact on, even can't draw the hole.
Therefore be necessary to arrange a kind of device, can when joint need slip casting, transfer slip casting core pipe immediately and carry out slip casting, the time before the minimizing slip casting, win the quality time for speedily carrying out rescue work.
The utility model content
Because the problems referred to above, the utility model provides a kind of underground continuous wall connector grouting device, the I shape steel plate for sealing water that described diaphragm wall comprises reinforcing cage and is connected in this reinforcing cage joint, described device comprises two steel pipes, be welded in the junction of frange plate and the web of described I shape steel plate for sealing water respectively, equally spaced a plurality of slurry discharging holes, the described steel pipe overcoat rubber sleeve close protection of being provided with on the described steel pipe.
Further, described steel pipe is that common coating steel pipe by diameter 50mm is made.
Further, be provided with a described slurry discharging hole every 1m on the described steel pipe.
Further, described steel pipe is by the mantle fiber spreading.
Underground continuous wall connector grouting device of the present utility model, the ground-connecting-wall concreting is finished, find that there is mass defect in the joint before the soil excavation or in the soil excavation process, when needing slip casting, can transfer slip casting core pipe by this steel pipe immediately, carry out slip casting by this steel pipe fast, reduce carrying and draw hole equipment and draw the hole again and transfer the Grouting Pipe operation, save the joint slip casting preparation time, guaranteed construction safety.

Fig. 2 is the thin portion connection diagram of underground continuous wall connector grouting device of the present utility model.
Fig. 3 is the structural representation of the steel pipe of underground continuous wall connector grouting device of the present utility model.
The specific embodiment
Cooperation is referring to Fig. 1 and shown in Figure 2, the I shape steel plate for sealing water 20 that diaphragm wall comprises reinforcing cage 10 and is connected in these reinforcing cage 10 joints, underground continuous wall connector grouting device of the present utility model comprises two steel pipes 30, be welded in the junction of frange plate 21 with the web 22 of described I shape steel plate for sealing water 20 respectively, described steel pipe 30 is by the mantle fiber spreading, and described steel pipe 30 is gone into groove with reinforcing cage 10.Further, described steel pipe 30 is that common coating steel pipe by diameter 50mm is made.
Referring to shown in Figure 3, be provided with a slurry discharging hole 31 every 1m on the described steel pipe 30, and overcoat rubber sleeve close protection.When the underground continuous wall connector defectiveness needs slip casting, can carry out slip casting by this steel pipe 30 fast.Wherein, at steel pipe 30 overcoat rubber sleeve close protections, pressure is bigger during owing to slip casting, can guarantee that steel pipe 30 can from inside to outside carry out slip casting, and concrete can not pass back into steel pipe 30 from outside to inside, and steel pipe 30 inside are blocked.
The above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
