Description

FRP gallery

technical field

The utility model belongs to the technical field of urban public facilities and relates to a glass steel pipe gallery.

Background technique

The underground comprehensive pipe gallery is a municipal public facility that implements unified planning, design, construction and maintenance. It is built underground in the city and used to lay municipal public pipelines. It refers to the centralized laying of electricity, communications, radio and television, water supply and drainage in the city , heat, gas and other municipal pipelines in public tunnels. The existing reinforced concrete pipe gallery has disadvantages such as high cost and difficult construction.

Contents of the invention

In order to overcome the defects of the prior art, the utility model designs a glass steel pipe gallery. The structure of the pipe wall is reasonable and advanced, which can give full play to the role of the material. On the premise of satisfying the use strength, the steel degree is improved, and the stability and safety of the product are guaranteed. reliability.

The specific technical solution adopted by the utility model is: the glass steel pipe gallery, including the pipe body, the key is: the pipe body is a cylindrical structure, and the pipe wall of the pipe body includes an inner lining arranged in sequence from the inside to the outside and fixedly connected layer, the first fiber winding layer, the sand layer, the second fiber winding layer and the outer protective layer, the bottom of the pipe body is provided with a walkway layer, and the walkway layer is fixedly connected with the inner lining layer.

The wall thickness of the pipe body is 30-80 mm, and the inner diameter is 2400-4000 mm.

The width of the upper end surface of the aisle layer is greater than or equal to 900mm, and the maximum distance between the upper end surface of the aisle layer and the lower end surface of the aisle layer is 300mm.

A plurality of reinforced steel pipes are arranged on the outer wall of the pipe, and all the reinforced steel pipes are arranged at equal intervals along the axial direction.

The shape of one end of the pipe body is a socket, and the shape of the other end of the pipe body is a socket.

The walkway layer is a layered structure made of plain concrete.

The beneficial effects of the utility model are: the pipe body of the pipe gallery adopts glass fiber reinforced plastic pipe, the pipe wall structure is reasonable and advanced, and the role of the material can be fully exerted. On the premise of satisfying the use strength, the rigidity is improved, and the stability and reliability of the product are guaranteed. The bottom of the pipe gallery is made of concrete as the walkway, which meets the requirements of use. The pipe gallery has a simple overall structure, light weight and high strength, convenient transportation and convenient construction, which greatly reduces the cost of the comprehensive pipe gallery.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:

Specific embodiments, as shown in Figure 1 and Figure 2, the glass steel pipe gallery includes a pipe body, the pipe body is a cylindrical structure, and the pipe wall of the pipe body includes an inner lining layer that is sequentially arranged and fixedly connected from the inside to the outside 1. The first fiber winding layer 2, the sand layer 3, the second fiber winding layer 4 and the outer protective layer 5. The bottom of the pipe body is provided with a walkway layer 6, and the walkway layer 6 is fixedly connected with the inner lining layer 1. The pipe body The wall thickness is 30-80mm, the inner diameter is 2400-4000mm, the width of the upper end surface of the walkway layer 6 is greater than or equal to 900mm, and the maximum distance between the upper end surface of the walkway layer 6 and the lower end surface of the walkway layer 6 is 300mm.

As a further improvement of the utility model, a plurality of reinforced steel pipes 7 are arranged on the outer wall of the pipe, and all the reinforced steel pipes 7 are arranged at equal intervals along the axial direction, which can further enhance the strength of the pipe gallery.

As a further improvement to the utility model, one end of the pipe body is in the shape of a socket, the other end of the pipe body is in the shape of a socket, and the adjacent pipe gallery is a socket connection, which is convenient and quick to disassemble and save time and effort.

As a further improvement of the utility model, the walkway layer 6 is a layered structure made of plain concrete, which can save production costs on the premise of meeting the use strength.
