Abstract
The utility model relates to the category of underground construction, in particular to a joint box for an underground continuous wall. The specific scheme is that the joint box is an approximate trapezoidal box and is characterized in that the joint box is close to one side of a joint, a concave guide groove is arranged at a central line of the joint box, and a magnet is locally arranged on the concave guide groove. The joint box for the underground continuous wall has the advantages that the joint box can be tightly attached to an underground continuous wall joint constantly, the joint is not deformed to affect subsequent construction, concrete can be effectively prevented from flowing around an adjacent groove section during concreting, and the joint construction quality is improved.
Description
Technical field
The utility model relates to the underground building class, is specifically related to a kind of joint case for diaphragm wall.
Background technology
Diaphragm wall is the safest structure of Extra-Deep Foundation Pit, along with perfect, quick construction, the convenience of the reduction of cost, technique, uses more and more extensive in the deep foundation pit supports such as subway, Fang Jian.Because diaphragm wall is interconnected with certain joint form by unit groove one by one and forms, actual is not continuous, therefore the joint density between the underground continuous wall groove segment is extremely important, the joint construction quality is if there is problem, to cause the engineering underground structure Seepage to occur, directly have influence on the use of engineering underground structure, use function but also processing that seepage not only affects building are very difficult, but are difficult to guarantee seam quality on the traditional handicraft.Wherein one of topmost reason is for when carrying out concreting in the first phase groove section, and the traditional jointing case adopts the sand bag to fill or the Simple joint case, is difficult to prevent that concrete from streaming to the second stage of groove section joint.Therefore those skilled in the art be badly in need of a kind of can be closely connected in the joint case of joint, effectively prevent from streaming concrete and enter the second stage of groove section joint.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of joint case for diaphragm wall is provided, this joint case is by offering groove at its side center line near joint, so that with coupling and the guiding of joint, simultaneously at the embedded magnet of bottom portion of groove, so that the joint case is close to the joint of diaphragm wall by magnetic force.
The utility model purpose realizes being finished by following technical scheme:
A kind of joint case for diaphragm wall is arranged at the underground continuous wall connector place, and described joint case is a trapezoidal cabinet, it is characterized in that described joint case near on the side of described joint, is positioned at its position of center line place and is provided with a matrix gathering sill.
Be provided with magnet along part on the described matrix gathering sill.
Described matrix gathering sill bottom offers groove, and described magnet is embedded in the described groove.
Described matrix gathering sill has the trapezoid cross section.
The utility model has the advantages that the joint case can closely be affixed with underground continuous wall connector, guarantee that joint is indeformable and affect follow-up construction, can prevent effectively that when concreting concrete from streaming to the adjacent grooves section, improve the joint construction quality.
Description of drawings
Fig. 1 is the joint design schematic diagram with the tubular guide channel of the present utility model;
Fig. 2 is joint box structure schematic diagram of the present utility model;
Fig. 3 is that in advance groove section joint of the present utility model and joint case are laid the construction schematic diagram.
The specific embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-3, mark 1-7 is respectively among the figure: joint 1, guide pipe 2, reinforcing cage 3, grouting iron sheet 4, joint case 5, magnet 6, groove 7.
Embodiment: as shown in Figure 1, 2, 3, present embodiment relates to a kind of joint case for the underground continuous wall connector place.The profile of joint case 5 is a trapezoidal cabinet, offer the groove 7 of a trapezoid cross section at its side center line near joint 1, the dual-side that is the groove 7 of trapezoid cross section slopes inwardly, form gradient slideway when being convenient to guide pipe 2 and entering, for example the bottom of groove 7 is wide is 70cm, and the pipe diameter of guide pipe 2 is 48cm; Offer a groove in the base plane of groove 7, and at the inner placement of groove magnet 6, so that joint case 5 can be close to joint 1 by magnetic force when construction.
As shown in Figure 3, below be the concrete steps of joint case 5 in construction of diaphragm wall:
1. at first joint 1 is installed on the reinforcing cage 3 in the first phase groove section, and the integral solder moulding, if when the ground wall degree of depth is darker, in the marginal portion of joint 1 grouting iron sheet 4 is installed, prevent the risk that concrete streams; Wherein said joint 1 partly is made of flanging dull and stereotyped, that be positioned at the wing plate of dull and stereotyped both sides and be positioned at the wing plate edge, and the guide pipe 2 of a tubular is set at the center line of joint 1.
2. thereafter joint case 5 is fitted tightly by guide pipe 2 and joint 1; For guarantee joint case 5 can be as much as possible near the guide pipe 2 of tubular, offer a trapezoidal groove 7 at joint case 5 and the binding face of guide pipe 2, and offer a groove and embedded magnet 6 on the plane of groove 7 bottoms, thereby make joint case 5 in transferring process, magneticaction occurs magnet 6 can fit tightly the guide pipe 2 of joint case 5 and joint 1 all the time, effectively prevents from streaming concrete and enters the second stage of groove section joint.
3. then reinforcing cage 3 is transferred in the first phase groove section, and carry out the concrete operation, in the concrete process, driven joint 1 place of a tamper in reinforcing cage 3 by crane and do tamping operation on the vertical direction.
4. behind concrete initial set, joint case 5 is extracted.
In actual applications, joint case 5 can effectively prevent concrete streaming, and has guaranteed construction quality.
Claims (4)
1. a joint case that is used for diaphragm wall is arranged at the underground continuous wall connector place, and described joint case is a trapezoidal cabinet, it is characterized in that described joint case near on the side of described joint, is positioned at its position of center line place and is provided with a matrix gathering sill.
2. a kind of joint case for diaphragm wall according to claim 1 is characterized in that being provided with magnet along part on the described matrix gathering sill.
