The structure comprises a concrete pack and a cable duct bank; concrete pack reinforcements are all broken at the expansion joint; a filling plate is arranged at the expansion joint; a hole is formed in the filling plate through which the cable duct bank can pass; each side of the filling plate is smaller than the concrete pack in size; a groove consisting of the concrete in the pack and the filling plate is plugged by sealing paste; a connecting reinforcement is arranged in the concrete pack; one end of the connecting reinforcement is bound and lapped with the concrete pack reinforcement, and the other end of the connecting reinforcement is a free end of an outer sleeve; the sleeve is plugged by a wooden plug at a non-connecting reinforcement stretching end. According to the device disclosed by the invention, a sleeve is sleeved at one end of each connecting reinforcement at the expansion joint, free stretching can be realized, the damage on the power and communication duct banks caused by the concrete deformation is effectively relieved, and good protection performance is realized.
Description
Technical field
The present invention relates to the expanded joint structure that a kind of building site is used, especially a kind of cable duct bank concrete pack expanded joint structure and job practices thereof.
Background technology
Along with the development of electric power communication engineering technology, the distance of manhole is in continuous increasing at present, and comb adopts the situation of the form of structure of steel concrete to get more and more.And in Shanghai etc. similarly in soft foundation, the differential settlement of structure is that electric power and telecommunications comb are sealed and faced maximum hidden danger.Before prior art, conventional way is to keep somewhere constuction joint, and constuction joint place layering concreting, stay the stepped stubble that connects.Its reinforcing bar at this constuction joint place can not disconnect, and after having built, relies on the pulling force of reinforcing bar to avoid fully or reduces distress in concrete.Because concrete crack is inevitable, only adopt the method for " resisting " not deal with problems, can cause the red soil pipe by drawing crack, destruction because of the contraction of concrete itself, the problems such as differential settlement of soft foundation on the contrary, the quality problems such as finally cause that comb leaks.Korean Patent KR2010123192A discloses the shrinkage joint of using on a kind of building site, heat-resisting back lining materials is inserted gap, base plate has the coating aggregate, flexible joint and concrete structure flexibly connect, base plate is fixed on the floor side of flexible joint to cover gap and heat-resisting back lining materials, the mixing elastomeric polymer of flexible joint in the coating aggregate forms, rubber tile is fixed between base plate and shrinkage joint, although this patent has solved the flexible problem of concrete, how not solve the impact of reinforced concrete structure sedimentation on the structure interior conduit but do not relate to.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cable duct bank concrete pack expanded joint structure, and the job practices of this expanded joint structure, caused be out of shape drawing crack, destruction with differential settlement to solve cable sleeve in existing comb concrete pack by concrete is flexible, and the quality problems such as finally cause that comb leaks.
For realizing above-mentioned technique effect, the invention discloses a kind of cable duct bank concrete pack expanded joint structure, comprise concrete pack, cable duct bank, wherein, the arrangement of reinforcement of described concrete pack is located whole disjunctions at shrinkage joint, place, described shrinkage joint is provided with infill panel, on described infill panel, perforate is passed for described cable duct bank, the every limit of described infill panel is little than the concrete pack size, the groove be comprised of described concrete pack inner concrete and described infill panel is clogged by sealing compound, one connecting reinforcement is arranged in described concrete pack, the arrangement of reinforcement colligation overlap joint of described connecting reinforcement one end and described concrete pack, the free end that the described connecting reinforcement other end is the overcoat sleeve pipe, described sleeve pipe adopts stopper to carry out shutoff at disconnected reinforcing bar inserting end.
Described structure is further improved and is, the outside, place, described cable duct bank shrinkage joint is enclosed with kraft.
Described structure is further improved and is, described concrete pack is square.
Described structure is further improved and is, described sleeve pipe is the PVC sleeve pipe.
Described structure is further improved and is, described infill panel is the polyethylene foam plate.
Described structure is further improved and is, described sealing compound is the poly-sulphur sealing compounds of two components.
The invention also discloses a kind of cable duct bank concrete pack expanded joint structure job practices, described job practices comprises the following steps:
Step 1, according to the distributed steel requirement of concrete pack, carry out the arrangement of reinforcement colligation, and in the position, shrinkage joint, arrangement of reinforcement all disconnects;
The present invention has given full play to the thought of " anti-put in conjunction with ", carries out the control of the flexible destruction of bringing with differential settlement of concrete, and its advantage is:
1) its shrinkage strain of the concrete structure of distance is larger, the built-in PVC sleeve pipe of the present invention, kraft etc. can be free to slide medium, and the polyethylene foam plate, in the concrete pack of long distance, can meet the distortion needs of electric power and communication cable comb concrete pack structure.
2) in concrete pack, be cable duct bank, at place, shrinkage joint cable duct bank outer wrapping kraft, can be so that the cable duct bank free-extension, and do not destroy pipeline itself, joint filling board is set in shrinkage joint, after the concreting of both sides, the outside, shrinkage joint filling one strata sulphur sealing compound, can play good sealing effect.
3) every tens meters settings this shrinkage joint together, the connecting reinforcement at place, shrinkage joint, an end cover has pvc pipe, can realize free-extension, effectively alleviates the destruction of concrete deformation to electric power and communication comb, plays good protective value.
4) under soft foundation, the destruction of concrete structure is mainly reflected in to the differential settlement aspect, by the setting of this expanded joint structure, can adapts under Soft Soil, the control of concrete structure differential settlement harm.
5) easy construction of the present invention, installation are simply.
