Abstract

FRP pipe corridor, including the body, the key is: the body be cylindrical structures, the pipe wall of body is including set gradually and fixed connection's inner liner, first fibre winding layer, sand inclusion layer, second fibre winding layer and external coating from inside to outside, the bottom in the body is provided with pavement layer, pavement layer and inner liner fixed connection. Pipe wall advanced person rational in infrastructure, can full play the effect of material, satisfying under the prerequisite of using intensity, improved rigidity, guaranteed the stability and the reliability of product, simple structure, light weight, high strength, the transportation is convenient, the construction is convenient, greatly reduced utility tunnel's cost.

Description

Glass Steel Tube corridor

Technical field

The utility model belongs to urban public utilities technical field, it relates to Glass Steel Tube corridor.

Background technology

Underground pipe gallery implements unified planning, design, construction and maintenance, it is built in underground, city, for laying the public utility of municipal public use pipeline, refer to the public tunnel laying the municipal pipelines such as electric power, communication, broadcast television, feedwater, draining, heating power, combustion gas for concentrating in underground, city. There is the shortcomings such as cost height, constructional difficulties in existing reinforced concrete pipe gallery.

Summary of the invention

The utility model, in order to overcome the defect of prior art, devises Glass Steel Tube corridor, and structural pipe wall is rationally advanced, can give full play to the effect of material, under the prerequisite meeting working strength, it is to increase steel degree, ensure that the stability of product and reliability.

The concrete technical scheme that the utility model is taked is: Glass Steel Tube corridor; comprise pipe body; it is crucial that: described Guan Tiwei is columnar structured; the tube wall of pipe body comprises the air retaining wall, the first fiber winding layer, folder layer of sand, the 2nd fiber winding layer and the outer protective layer that arrange successively from inside to outside and be fixedly connected with; bottom in pipe body is provided with away channel layer, walks channel layer and is fixedly connected with air retaining wall.

The wall thickness of described pipe body is 30～80mm, and internal diameter is 2400～4000mm.

The described width walking channel layer upper surface is more than or equal to 900mm, and walking channel layer upper surface to the ultimate range walked between channel layer lower surface is 300mm.

Being provided with multiple reinforcement steel pipe on described tube wall, all reinforcement steel pipes are arranged at interval vertically etc.

The shape of described pipe body one end is grafting mouth, and the shape of the pipe body the other end is for accepting mouth.

Described channel layer of walking is the laminate structure being made up of plain concrete.

The beneficial effects of the utility model are: pipe corridor pipe body selects fiber reinforced plastic pipe, structural pipe wall is rationally advanced, the effect of material can be given full play to, under the prerequisite meeting working strength, improve steel degree, ensure that the stability of product and reliability, adopt concrete to do aisle bottom pipe corridor, meet service requirements. Pipe corridor one-piece construction is simple, high-strength light, convenient transportation, construction are convenient, greatly reduces the cost of pipe gallery.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to diagram.

In accompanying drawing, 1, air retaining wall, the 2, first fiber winding layer, 3, folder layer of sand, the 4, the 2nd fiber winding layer, 5, outer protective layer, 6, walk channel layer, 7, strengthen steel pipe.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:

Specific embodiment, such as Fig. 1, shown in Fig. 2, Glass Steel Tube corridor, comprise pipe body, described Guan Tiwei is columnar structured, the tube wall of pipe body comprises the air retaining wall 1 arranging successively from inside to outside and being fixedly connected with, first fiber winding layer 2, folder layer of sand 3, 2nd fiber winding layer 4 and outer protective layer 5, bottom in pipe body is provided with away channel layer 6, walk channel layer 6 to be fixedly connected with air retaining wall 1, the wall thickness of pipe body is 30～80mm, internal diameter is 2400～4000mm, the width walking channel layer 6 upper surface is more than or equal to 900mm, walking channel layer 6 upper surface to the ultimate range walked between channel layer 6 lower surface is 300mm.

As to further improvement of the utility model, tube wall being provided with multiple reinforcement steel pipe 7, all reinforcement steel pipes 7 are arranged at interval vertically etc., it is possible to strengthen the intensity of pipe corridor further.

As to further improvement of the utility model, the shape of pipe body one end is grafting mouth, the shape of the pipe body the other end, for accepting mouth, inserts connection for holding between adjacent tubes corridor, convenient to disassembly, time saving and energy saving.

As to further improvement of the utility model, walking channel layer 6 is the laminate structure being made up of plain concrete, under the prerequisite meeting working strength, it is possible to save production cost.
