Abstract
The invention relates to underground buildings, specifically to a construction method for joints of underground continuous walls. The construction method is provided to effectively solve the water leakage defect of the current joints of underground continuous walls. According to the invention, a joint approximating to a V-shaped steel plate is mounted at the juncture of a unit wall, and a tubular guide protruding rib is formed on the outer surface of a flat plate of the joint to perform the function of guiding; a joint box, a wall brusher and a temping machine with corresponding grooves are matched, so that the joints are closely adhered to the wall in construction. A guide rail can be added to guarantee the cohesive force between later poured concrete and the joint, so as to prevent the concrete from being separated from the joint and reduce the channel which leaks water, and further excellently prevent water leakage. The construction method has the advantage that the water leakage defect of the joints of underground continuous walls can be well solved, so that the underground continuous walls can be integrated more closely to ensure that no water leaks from the joints.

Detailed description of the invention
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
What in accompanying drawing 1-8, label 1-11 represented is joint 1, joint case 2, magnet 3, reinforcing cage 4, guiding fin 5, matrix gathering sill 6, grouting iron sheet 7, wire brush 8, concavity gathering sill 9, brush wall device 10, hanger 11, fin plate 12, crane 13, tamper 14.
Embodiment: as shown in Fig. 1 ~ 8, the present invention relates to underground building class, is specifically related to a kind of construction method for underground continuous wall connector.The construction of underground continuous wall jointing method that the present embodiment relates to specifically comprises reinforcing cage 4, the joint 1 be welded on reinforcing cage 4, the joint case 2, brush wall device 10 and the tamper 14 that fit tightly with joint 1; Specific construction step of the present invention is as follows:
1. first joint 1 is arranged on the reinforcing cage 4 in first phase groove section, and integral solder is shaping, if when the ground wall degree of depth is darker, install grouting iron sheet 7 in the marginal portion of joint 1, reduces the risk that concrete streams; Wherein said joint 1 is made up of wing plate that is dull and stereotyped, that be positioned at dull and stereotyped both sides and the tuck portion that is positioned at wing plate edge, and on the center line of joint 1, arrange a guiding fin 5, and guiding fin 5 is made up of O shape pipe.
2. thereafter joint case 2 is fitted tightly along guiding fin 5 with joint 1; For ensureing that joint case 2 can as much as possible near tubular guiding rail 5, trapezoidal matrix gathering sill 6 offered by joint case 2 with the binding face of guiding rail 5, and plane bottom trapezoidal matrix gathering sill 6 offers a groove and embedded magnet 3, thus make joint case 2 in decentralization process, magnet 3 is had an effect and joint case 2 and joint 1 can be fitted tightly all the time, ensure the unlikely distortion of joint 1 and affect subsequent construction, effectively preventing streaming concrete enters the second stage of groove section joint simultaneously.The trapezoidal matrix gathering sill 6 that its center tap case 2 is offered, its groove dual-side slopes inwardly, form the gradient slideway when tubular guiding fin 5 be convenient on joint 1 enters, such as, bottom trapezoidal matrix gathering sill 6 wide is about 60cm, and the diameter of tubular guiding fin 5 is about 48cm.
3. then reinforcing cage 4 is transferred in first phase groove section, and carry out concretely building operation, in concrete casting process, joint 1 place of tamper 14 in reinforcing cage 4 is driven to do tamping operation on vertical direction by crane 13, along with the rising of concrete surface, tamper 14 is upwards promoted along guiding fin 5, and 5 ~ 6m below the Transducers Embedded in Concrete face, bottom remaining tamper 14; After concreting to design elevation, tamper 14 is slowly at the uniform velocity extracted.Wherein tamper 14 can wipe the folder mud burning into sand at guiding fin 5 structure place off in upper and lower withdrawing process, ensure that the closely connected of concrete and joint 1 well, and effective filling is led the closely knit of fin 5 inner concrete.
4. when after concrete initial set, joint case 2 is extracted.
5. the second stage of groove section of groover excavation next-door neighbour after; Treat that described the second stage of groove section is dug, the tubular guiding fin 5 inserted by opening O shape concavity gathering sill 9 on brush wall device 10 on joint 1 forms mandatory brush wall, and make the spacing between the brush wall of brush wall device 10 and joint 1 keep being separated by 20 ~ 30cm, ensure that wire brush on brush wall device 10 8 and joint 1 fit tightly and wire brush 8 is applied to frictional force on joint 1; Crane 13 is by catching on hanger 11 in the vertical direction handling brush wall device 10 subsequently, first the mass concrete be attached on joint 1 and silt particle are rooted out moving downward in process the fin plate 12 bottom the brush wall device 10 that leads, the tiny silt particle be attached on joint 1 brushes totally by wire brush 8 subsequently.Its center tap 1 is cleaned with water part for tab portions that is dull and stereotyped and dull and stereotyped both sides by wire brush 8.
6. after wall cleaning process to be brushed terminates, basic skill or training is clearly carried out to described the second stage of groove section and does, then transfer reinforcing cage and carry out concrete building, complete the joint construction that all grooves are intersegmental and so forth.
As shown in Fig. 9,10,11,12, the shape of the guiding rail 5 described in the present invention is not limited to pipe O shape, also can be T steel plate.Along with guiding fin 5 shape becomes T steel plate, the groove of tamper 14 also changes into T-shaped groove thereupon, and the concavity gathering sill 9 of brush wall device 10 also becomes T-shaped concavity gathering sill thereupon.Therefore those skilled in the art obviously understands the alteration of form along with guiding fin 5, and the groove on tamper 14 and brush wall device 10 also will change into the groove shapes matched with it thereupon.
The present invention adds guiding fin 5 relative to traditional handicraft, the guide rail that described guiding fin 5 can be used as later stage brush wall and makes firm by ramming, thus the effect ensureing brush wall better and make firm by ramming; Extend infiltration path, more effectively reduce the risk of percolating water, percolating water can be prevented and treated better; After ensureing, the adhesion stress of pouring concrete and joint 1, prevents the disengaging between concrete and joint 1, reduces the passage of percolating water, prevents the generation of percolating water well.
