Description
Technical field
The present invention relates to a kind of underground pipe gallery, specifically a kind of assembled underground pipe gallery.
Background technology
Underground pipe gallery is to be built in structures and affiliated facility that Urban Underground is used to accommodate all kinds of municipal engineering pipelines.
Underground pipe gallery is divided into main line piping lane, branch line piping lane and cable piping lane etc. according to species.Which kind of underground pipe gallery applied using
Work mode depends on cost and the feasibility implemented, and main line piping lane is because section is big, slots from the big generally use of great, quantities
Method, cast-in-place form of construction work.Using fluting method construction, it is impossible to adapt to push pipe demand.Rainy day, northern area winter can not construct.
The construction operation time is grown, situ wet operation heavy workload, needs longer concrete curing Enhanced time.Limited by building-site condition
System, long time period, and the concrete impermeability made easily locally is oozed not as the concrete made in factory
Easily there is construction crack, contain body sidewall entire crack etc. in leakage, culvert pipe.
Rubber water-proof band connection is used between the box culvert segmentation of field fabrication, the drawback is that anti-uneven settlement of foundation ability
Difference, interface easily occur dislocation up and down and deformation, cause waterstop by drawing crack；Cast-in-place construction need to stay branch modular space, and earth volume increases,
It is also big to surrounding enviroment destructive power, it is unfavorable for the protection of ecological environment.
The content of the invention
It is an object of the invention to provide a kind of construction efficiency that can improve underground pipe gallery, the quality of underground pipe gallery is lifted
Assembled cast-in-place concrete structure non-dismantling formwork piping lane.
The object of the present invention is achieved like this：Including cast-in-place concrete bottom plate, two prefabricated non-dismantling formwork system wallboards
Exempt to tear floorboard open with prefabricated, wall anchor bar, the prefabricated non-dismantling formwork system are reserved in the both sides of the cast-in-place concrete bottom plate
System wallboard includes metal truss and the non-dismantling formwork installed in metal truss both sides, metal truss laying reinforcing bar, described prefabricated to exempt from
Tearing floorboard open includes bottom surface non-dismantling formwork and the bar-mat reinforcement being laid on the non-dismantling formwork of bottom surface, two prefabricated non-dismantling formwork system walls
Plate vertical runs in the both sides of cast-in-place concrete bottom plate, it is prefabricated exempt to tear floorboard open be laid in two prefabricated non-dismantling formwork system wallboards
Top, have casting concrete load bearing wall in the gap between the non-dismantling formwork of prefabricated non-dismantling formwork system wallboard, it is prefabricated to exempt to tear open
There is casting concrete top layer on floorboard.
The present invention can also include：
1st, the wall anchor bar is N-shaped.
2nd, the reinforcing bar in the metal truss in prefabricated non-dismantling formwork system wallboard and the wall anchor in cast-in-place concrete bottom plate
Gu reinforcing bar is connected.
3rd, the height of the non-dismantling formwork on the inside of prefabricated non-dismantling formwork system wallboard is less than non-dismantling formwork on the outside of metal truss
Highly, the prefabricated bar-mat reinforcement for exempting to tear open floorboard stretches out the edge of bottom surface non-dismantling formwork and is connected with the reinforcing bar in metal truss.
4th, the reinforcing bar in metal truss is vertical with metal truss.
5th, the length direction of piping lane is segmental structure, is connected between two sections by flexible connection rubber sealing.
6th, there is the division wall that piping lane is divided into different functional areas in piping lane.
Underground pipe gallery is designed to assembling with pouring the form being combined by the present invention, and the agent structure of piping lane is on construction ground
Completed outside by the form of batch production, assembled at the construction field (site), improve the speed of application of underground pipe gallery, reduce construction
Difficulty.Some engineerings can not make concrete floor basis, before piping lane is installed, behind can earth backing, resume traffic.There is water
Under the conditions of can also construct, be not required to precipitation.
The bell and spigot of the present invention is flexibly connected using cushion rubber, and the preferable antidetonation resist displacement of energy, solves rigid interface sealing
The problem of by longitudinal tensioning, antidetonation resist displacement is impacted, and annex anti-corrosive durability is poor, and waterproof safeguard is few.
The main efficacy results of the present invention are embodied in：
1. relative to traditional construction mode, reduce the usage amount of plank sheathing, flitch supporting etc., reduce the comsumption of natural resources,
Reduce cost.
2. the prefabricated non-dismantling formwork system of batch production, improves speed of application and construction precision.
3. continuous cast-in-place construction, integral waterproofing good airproof performance.
