Abstract
The utility model relates to an underground continuous wall waterproof connecting device. The upper part of a bottom plate is fixedly connected with a channel plate whose section forms a trapezoid. The upper part of the channel plate is fixedly connected with two water stopping belt fixed plates. The inner side of each water stopping belt fixed plate forms a right angle, and the section of the water stopping belt fixed plate forms a trapezoid or other shapes. A rubber water stopping belt is embedded between the two fixed plates. The inner sides of the left and right ends of the channel plate are respectively embedded with a end plate. When the device is removed, the rubber water stopping belt is still embedded in the seam between two adjacent underground continuous walls to from a forms a waterproof connector. Because the structural form of the connector is similar to a tenon joint, the underground continuous wall used the device for construction has little clamping mud in the seam, has good waterproof effect and has strong anti-deformation performance.
Description
The utility model relates to construction of continuous concrete wall, and is especially relevant with the water joint device of diaphragm wall.
In construction of continuous concrete wall, the seepage of joint tends to bring very big influence to construction quality.It is circular fore shaft pipe that the junction device of existing diaphragm wall mostly adopts section configuration, and the structural form of its joint is semicircle, and this equipment also can play waterproof effect to a certain extent.But still come with some shortcomings.One, requirement could be excavated the adjacent slot section after the fore shaft pipe of last groove section is extracted on the technology, cause the mud of the concrete wall of seam one side to cover, form the mud skin, the groove section construction of the groove section of having constructed and adjacent not construction is long more blanking time, the mud skin that forms is just thick more, and the gap of seam is just big more, and the possibility of seepage action of ground water is also big more.Its two, under the situation of diaphragm wall displacement, seam tends to produce dislocation, twisting, has more quickened phreatic seepage flow.Its three, adopt the fore shaft pipe, auxiliary equipment is more during construction, has taken more construction plant, has also brought inconvenience to construction.Its four, require on the technology just it to be extracted before the concrete final set, otherwise will imbed in the concrete, cause the waste on the equipment.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of clay seam few, good water-proof effect, and anti-deformation is strong, the diaphragm wall water joint device of being convenient to construct.
For achieving the above object, the technical scheme of the utility model coloured silk is: also embed rubber fastening band betwixt with a base plate, a groove section, two waterstop fixed heads, form a diaphragm wall water joint device with left and right two end plates, after this device was removed, rubber fastening band was embedded in the seam of adjacent two sections diaphragm walls.
Waterstop section middle part is an open circles, and two ends are respectively a filled circles, links to each other by the rubber gusset.The spacing of two waterstop fixed heads is slightly less than the external diameter of waterstop hollow circle, and its profile height is slightly larger than half of waterstop width.
Left and right end plate difference build-in is in the inboard at frid two ends.Position at the close middle part of right end plate is provided with two alignment pins, and two locating holes of relative set on the first member plate are convenient to locate when two covering devices connect.Evenly arrange 5-7 bolts hole on the right end plate, 5-7 connecting holes of relative set on the first member plate, and offer a hand hole near the position of end plate at the left end of base plate, be convenient to the connection of bolt.
The section configuration of frid is an antiparallelogram, and the section configuration of two waterstop fixed heads is inboard trapezoidal, triangle or other shapes for the right angle.
Compared with prior art, the utlity model has following advantage:
1, rubber fastening band is embedded in the concrete joint of diaphragm wall, stop underground water from seam, to permeate.
2, because the joint form of this device is similar to joggle, therefore, anti-deformation is strong.
3, time of contacting with mud of seam one side short, mud skin residual on its wall concrete is few, makes seam tightr, has suppressed phreatic seepage flow.
4, because this device has special form of structure, it is convenient therefore, to install, remove.
Auxiliary equipment is few when 5, constructing, and occupied ground is little, and is both economical.
6, this apparatus structure is simple, and integrated cost is lower.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a water joint device profile;
Fig. 2 is the front view of water joint device first member plate;
Fig. 3 is the front view of water joint device right end plate;
Fig. 4 is the sectional view of water joint device;
Fig. 5 is the profile of the adjacent two sections diaphragm walls in concrete pouring back.
As shown in Figure 1, the affixed frid 4 on the top of base plate 1, the affixed two waterstop fixed heads 5 and 6 separated by a distance in the top of frid 4, form a waterstop embedded groove between two fixed heads, embed rubber fastening band 7 therebetween, again respectively at the two ends of frid 4 build-in just like Fig. 2, while shown in Figure 3 end plate 2,3 perpendicular to base plate 1 and frid 4.It is an open circles that rubber fastening band is made as shown in Figure 1 the middle part, and two ends are respectively a filled circles, and the form that is connected by the rubber gusset.The width of waterstop embedded groove is slightly less than the external diameter of waterstop hollow circle, highly be roughly half of waterstop width, after this device is removed as shown in Figure 5, half embedding of rubber fastening band is stayed in the diaphragm wall after the moulding, second half is then imbedded in the concrete when the concrete pouring of adjacent segment diaphragm wall, thereby make in the seam of diaphragm wall and embedded rubber fastening band, form water joint.
For the ease of the connection between two covering devices, the form that the left and right end plate 2,3 of this device is made respectively shown in Fig. 2,3,4.Position at first member plate 2 close middle parts is provided with two alignment pins, and the corresponding site of right end plate 3 is provided with two locating holes.Simultaneously, according to the difference of diaphragm wall thickness, on right end plate 3, evenly arrange 5-7 bolts hole, 5-7 connecting holes of same area relative set at first member plate, and as shown in Figure 4, offer a hand hole 8 near the position of first member plate at the base plate left end, be convenient to the connection of bolt.
During use, should be according to the difference of the underground continuous wall groove segment degree of depth, it is isometric that this device is made 3 meters, 6 meters and 9 meters, both can singly overlap use, also can be the use that fuses of some covers, its total length should be slightly larger than the groove section degree of depth.This device of some covers fused when using, and the wedgewise closed is done in a frid end of overlapping bottom, so that in the soil body at the bottom of the insertion groove.
During construction, after at the bottom of the groove Duan Qing, can lay this device.With the left end of this device down, right-hand member up when laying.Can lay simultaneously in two sides of groove section; Also can lay a side earlier, treat install reinforcing cage after, lay opposite side again.
During near the bottom, the drag hook that can utilize grooving grab bucket side to install is removed this device at adjacent slot section soil excavation.Certainly, also can adopt other method that it is removed.
