For preventing water slop failure from causing foundation construction thing to be destroyed, there is the syndeton of various impervious wall and hydraulic structure at present.As the publication number Chinese patent that is CN 203222776 U discloses the syndeton of a kind of barrage foundation diaphragm wall and gate dam building, comprise seepage prevention, gate dam building and riverbed concrete cushion; Highly foaming polyethylene plate and precast concrete frid is disposed with from bottom to top between the end face of seepage prevention and gate dam building; Gap is provided with between seepage prevention and the surface, seepage prevention upstream and downstream of gate dam building junction, bury " U " type Copper water stop in the middle part of the gap of upstream side underground, the sealing piece of " U " type Copper water stop sealing nose both sides respectively correspondence extends in seepage prevention and gate dam building; Be provided with neoprene rod in sealing nasal cavity, the gap being positioned at sealing nose top is filled with polysulfide sealant, and the gap being positioned at sealing nose bottom is filled with high pressure closed-cell polyvinylchloride plate; In the gap in downstream, be filled with high pressure closed-cell polyvinylchloride plate, the top in gap, downstream is filled with polysulfide sealant.Although this technical scheme can adapt to the distortion of gate dam base, there is a good sealing connection reliability.But the syndeton of this technical scheme mainly exists following not enough in actual applications:
(1) applicable surface is comparatively narrow, is mainly used in the connection of gate dam base plate and riverbed impervious wall, is not suitable for the building built on heterogeneous body and connects;
(2) for the situation that deflection is larger, particularly at reservoir filling and engineering operation initial stage, adopt said structure easily to occur stress raisers and be difficult to release, thus affecting the safety of structure;
(3) technique scheme is only provided with one sealing, when sealing due to problem on deformation occur destroy time, without any remedial measure.
Utility model content
For solving the problem, the utility model provides the horizontal connection structure between a kind of concrete cut and concrete structure.Thus solve the connectivity problem between running in Design of The Hydraulic Structure because of the structure of different-stiffness, different structure form, different deformation behaviours; Overcome concrete structure affects structure safety because easily there is local stress collection.
The utility model is achieved by following technical solution.
Horizontal connection structure between a kind of concrete cut and concrete structure, the concrete cut comprising concrete structure and be connected with concrete structure, described concrete structure is provided with the groove for connecting concrete cut, the section of described groove is square structure, in the upstream wall of groove be provided with structural joint between downstream wall and concrete cut, filling caulking material in described structural joint, the upstream and downstream of described groove is respectively arranged with one copper seal.
Be provided with subsider between described bottom portion of groove and concrete cut, in subsider, be furnished with reinforcing bar.
Pitch is filled with in described subsider.
Described concrete structure is positioned at subsider top and is provided with vent.
Described caulking material adopts pitch Chinese fir board or elastomeric material.
The width of described structural joint is 2cm.
The diameter of described vent is 15 ~ 25cm.
The beneficial effects of the utility model are:
Compared with prior art, the utility model has following remarkable advantage:
(1) the utility model is applied widely, not only be applicable to build between gate dam base plate and riverbed impervious wall and isotropic body be out of shape relatively little and be out of shape situation about comparatively coordinating, also be applicable to the building built on heterogeneous body, structure has the comparatively large and situation of deformation of deflection;
(2) the utility model can take the mode of heated asphalt to reach the effect of effectively release stress according to different periods;
(4) the utility model takes the mode of filling pitch between concrete structure and concrete cut, by pitch as sealing material, can guarantee the reliability of sealing between structure.
(5) by arranging twice copper sheet sealing, the Incoordinate deformation produced because of stressed and geologic process between concrete cut and concrete structure can be met, and meet sealing requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-concrete structure, 2-vent, 3-subsider, 4-reinforcing bar, 5-structural joint, 6-copper seal, 7-concrete cut.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, horizontal connection structure between a kind of concrete cut described in the utility model and concrete structure, the concrete cut 7 comprising concrete structure 1 and be connected with concrete structure 1, described concrete structure 1 is provided with the groove for connecting concrete cut 7, the section of described groove is square structure, in the upstream wall of groove be provided with structural joint 5 between downstream wall and concrete cut 7, filling caulking material in described structural joint 5, the upstream and downstream of described groove is respectively arranged with one copper seal 6.The technical program material requested is conventional material, easily purchases, the simple and convenient and quick construction of structure, convenient maintenance.Simultaneously by arranging twice copper sheet sealing, overcoming conventional attachment structure and being only provided with one sealing, when sealing occurs destroying due to problem on deformation, without any the deficiency of remedial measure.
Be provided with subsider 3 between described bottom portion of groove and concrete cut 7, in subsider 3, be furnished with reinforcing bar 4.
Pitch is filled with in described subsider 3.In structure sediment deformation phases, should by temperature more than asphalt heating to softening point.
Described concrete structure 1 is positioned at subsider 3 top and is provided with vent 2.
The degree of depth of described groove equals concrete cut 7 and the connecting length of concrete structure 1 and the size sum of subsider height.
