Description

A kind of assembled pipe gallery

Technical field

The invention belongs to assembled civilian infrastructure technical field, more particularly to a kind of assembled pipe gallery.

Background technology

Underground urban duct synthesis corridor (referred to as " pipe gallery "), i.e., build a tunnel space in Urban Underground, will The various utilities pipelines such as electric power, communication, combustion gas, heat supply, plumbing are integrated in one, equipped with special access hole, hoisting port and prison Examining system, implements unified planning, Uniting, unified construction and management.Pipe gallery is the important foundation for ensureing city operations Facility and " lifeline ", while played an important role to meeting people's livelihood primary demand and improving city integrated bearing capacity.

In recent years country widelys popularize city integrated piping lane construction, and urban transportation and environment are influenced in order to reduce construction, carried High quality, improve efficiency, shorten the construction period be piping lane construction inevitable requirement.If piping lane, into standard block, is transported in factory process Defeated to greatly improve speed of application to live quick-assembling, construction quality, shortens the construction period, and reduces road and takes.

Pipe gallery is the rectangular tubular structure formed by top plate, two lateral retaining walls and bottom plate integral cast-in-situ.It is small-sized at present Pipe gallery (sectional dimension be less than 3 meters × 4 meters) has fabricated construction at present, by the small comprehensive piping lane along its transversally cutting Into the rectangular element of two meters or so (length along pipe gallery axial direction is two meters or so), which is integrally formed knot Structure, carries out prefabrication scene and by presstressed reinforcing steel or is bolted integral.And for large-scale synthesis piping lane, (sectional dimension is big In 3 meters × 4 meters) constructed using live integral cast-in-situ due to the limitation of road transport, speed of application and construction quality often no To guarantee, and it is more to take road.

For large-scale piping lane there is presently no realizing that prefabrication and assembly construction constructs, it is primarily due to that there are problems with:

1st, according to the slit mode of small comprehensive piping lane, rectangular element monomer appearance and size is big, existing factory building height, lifting Equipment cannot meet to produce needs.

2nd, the rectangular element of cutting generally uses vertical storage at the construction field (site), it is therefore desirable to takes more place;

3rd, the rectangular element weight of cutting is larger (general weight is more than 30 tons), transport and during in-site installation to lifting equipment It is more demanding, increase equipment cost;

Utility model content

This practical new purpose is to overcome the shortcoming of prior art, there is provided a kind of assembled pipe gallery, Especially suitable for large-scale synthesis piping lane, so as to fulfill can prefabrication production, improve speed of application and construction quality, while can subtract Few equipment cost and road improvement occupancy situation, and large and small pattern synthesis piping lane is applicable in.

The utility model adopts the following technical solution:

A kind of assembled pipe gallery, it is characterised in that including being laid with and being located at the cast-in-place bed course of bottom vertically and show Several pipe gallery units for pour bottom plate, splicing successively vertically and a variety of connectors, each pipe gallery unit include position In both sides there is the prefabricated barricade of L-type of bottom plate stretching reinforcing bar and the prefabricated top plate positioned at top, the prefabricated top plate top surface to be additionally provided with Cast-in-place overlapping top plate overlapping layers, between the cast-in-place bed course and cast-in-place bottom plate, on the outside of L-type barricade and cast-in-place overlapping top plate overlapping Layer top surface is also equipped with waterproof layer;Wherein, the bottom plate of the prefabricated barricade of L-type stretches out reinforcing bar and the reinforcing bar in cast-in-place bottom plate, L-type are prefabricated Connected respectively by connector and cast-in-place concrete between prefabricated top end and the prefabricated barricade of adjacent L-type at the top of barricade.

Alternatively, the prefabricated barricade of the L-type bottom plate stretch out reinforcing bar by screw shell and connect reinforcing bar with it is described cast-in-place Bar connecting in bottom plate.

Alternatively, the step for supporting the prefabricated top plate and reserved pin hole are equipped with the top of the prefabricated barricade of the L-type;Its In, the step is higher by side template of the part of the prefabricated top plate as the cast-in-place overlapping top plate overlapping layers, passes through institute Reserved pin hole is stated to be connected with the prefabricated top plate pin.

Alternatively, the prefabricated barricade both ends of the L-type are equipped with uniformly distributed multiple reserved bolt with one end bent back mounting holes, reserved by this Hole is connected the adjacent prefabricated barricade of L-type by bolt with one end bent back.

The characteristics of the utility model is:

The utility model proposes assembled pipe gallery be by existing rectangular tubular by a kind of new fractionation mode Structure splits into two kinds of barricade, top plate plate-type components, and prefabrication production and transport to on-site consolidation is simultaneously bolted, bottom plate Cast-in-site stripe, top plate overlapping layers are connected into and are performed integrally.Prefabricated barricade and prefabricated top plate width after fractionation are generally no greater than 2.4 Rice, traffic condition license also can suitably increase surface member width so as to improve production, installation effectiveness.

Compared to cast-in-place construction, the beneficial effects of the utility model are:

1st, a kind of combinable comprehensive pipe gallery structure is provided for large-scale piping lane, makes large-scale synthesis piping lane can prefabrication life Production.

2nd, due to splitting into board-like unit, can multilayer pile up, save storage space.

3rd, since board-like unit weight is smaller, less lifting equipment can be selected in transport and when in-site installation, reduces equipment Expense.

4th, prefabricated top plate can use prestressed slab, reduce amount of reinforcement, reduce cost.

5th, since special fractionation connecting method make it that live bottom plate cast-in-site stripe, the concreting of top plate overlapping layers need not Live formwork, so as to improve construction efficiency, reduces operating expenses, ensures construction quality.
