Description

Overlap assembled underground pipe gallery

Technical field

The utility model is related to a kind of underground pipe gallery, and in particular to one kind overlapping assembled underground pipe gallery.

Background technology

Pipe gallery is one underground pipe gallery of construction under town road, by draining, heating power, combustion gas, electric power, communication, wide Lay included in the municipal pipelines such as electricity convergence union, and the facilities such as special access hole, dog-house are set, it is unified to build pipe Reason, saves pipeline itself independent structures and earth excavation, effectively intensive can utilize space resources.Its advantage is: Once excavate, concentrate construction, it is to avoid same section repeats to excavate;Greatly facilitate the cities such as electric power, communication, combustion gas, water supply and sewage The maintenance and maintenance of political affairs facility, reduce the expense repeatedly overhauled on road surface and the maintenance cost of utilities pipeline, maintain road surface The durability of integrality and all kinds of pipelines;Reduce the roofbolt of road and inspection shaft, the room of various pipelines etc., graceful city Landscape;Pipe gallery gut line compact and reasonable arrangement, is effectively utilized the space under road, has saved urban land.

Underground pipe gallery common at present is first constructed to bottom plate and side wall when construction, waits bottom plate and side After wall concrete setting, then set up scaffold on the bottom plate on the inside of side wall and lay concrete-pouring template, finally to top plate Poured, waited after concrete roof solidification, then form removal and scaffold.The setting up and remove not only to extend of scaffold is applied The work duration, the degree of difficulty of construction is also add, while also increasing construction cost.

Utility model content

For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is:One kind how is provided to apply Work is convenient, can shorten the construction period, reduces the overlapping assembled underground pipe gallery of construction cost.

In order to solve the above-mentioned technical problem, the utility model employs following technical scheme:

One kind overlapping assembled underground pipe gallery, includes the N surface sides of top plate, bottom plate and laterally spaced spread configuration Space between top plate and bottom plate is divided into N-1 piping lane by wall, N surface sides wall, and N is >=2 natural number, it is characterised in that:Often Surface side wall includes being fixedly connected on one by connector between two block gaps and the prefabricated panel be arrangeding in parallel, two pieces of prefabricated panels Rise, concrete sandwich has also been poured between two pieces of prefabricated panels, the opposite side that top plate includes being overlapped on two adjacent surfaces side wall is pre- The precast support plate on wallboard top processed and the concrete top layer on precast support plate and concrete sandwich top surface, prefabricated panel Upper and lower ends be extended with respectively many can extend into bottom plate and concrete top layer so that its respectively with bottom plate and concrete The perpendicular muscle that top layer is fixed together, two bond ends of precast support plate, which are respectively equipped with, can make to be located at prefabricated panel top The groove that the perpendicular muscle stretched out is passed through.

In the utility model, equally first bottom plate and side wall are constructed, while construction, precast support plate entered Row make, after the completion of the construction for treating bottom plate and side wall, directly by the precast support plate made be overlapped on adjacent two pieces of side walls it Between relative two pieces of prefabricated panels top, and the perpendicular muscle anchored end that prefabricated panel top is stretched out is then from precast support edges of boards edge Groove stretch out, it is not caused interference, while prefabricated panel again can to precast support plate offer support, treat precast support plate After installation, you can casting concrete top layer, construction is completed.The link for setting up scaffold is thus eliminated, it is prefabricated in addition Supporting plate can simultaneously be carried out when bottom plate and side wall are constructed, and shortened construction period, improved efficiency of construction, also make to apply Work more facilitates, while also reducing construction cost.
