Abstract
The utility model belongs to building materials, in particular to a concrete prefabricated square pipe. The concrete prefabricated square pipe comprises a pipe body 2, a taper plug 1 and a taper forced port 3. The concrete prefabricated square pipe is characterized in that a section of telescopic joint 4 is arranged in the middle of the pipe body 2, and the cross section of the pipe body 2 is manufactured into a square. Compared with a round pipe with the same diameter, the cross section flow capacity is big, the embedded pipe grooving area is small, and the concrete prefabricated square pipe has the telescopic performance. The concrete prefabricated square pipe has wide application range, such as urban underground comprehensive pipe galleries (common trenches) and the like.
Description
Technical field
The utility model belongs to structural material, particularly a kind of concrete prefabricated square tube.
Background technique
At present, China's comprehensive wiring, cable, for example electric power, communication, department such as move all take the cast in situs mode to build piping lane, and effect is low; In addition, China all is to adopt concrete prefabricated pipe in the underground conveying of liquid, compares with the square tube of 1 rice diameter and the pipe of 1.2 rice diameters, and the sectional area flow of pipe is less than the cross section flow of square tube, and the fluting area is relatively also big when underground buried tube.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, a kind of concrete prefabricated square tube that is applied to the city underground pipe gallery is provided.
The technological scheme that the utility model technical solution problem adopts is: a kind of concrete prefabricated square tube that formed by mouth by body, cone-shaped plug and taper, be characterized in the middle of body, establishing one section slip joint, and the body section is made square.
The beneficial effects of the utility model are: this square tube is bigger than the pipe sectional area flow of same diameter, and area is little during the pipe laying fluting, saves engineering work load; This square tube can be saved the duration as the city common trench, and waterproof sealing is good, helps urban construction; Be provided with slip joint and have telescopicing performance, solved and expanded with heat and contract with cold and be out of shape influence pipeline.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is concrete prefabricated square tube plan view;
Fig. 2 is the left side view of Fig. 1;
Fig. 3 is the right side view of Fig. 1.
1-cone-shaped plug among the figure; The 2-body; The 3-taper is subjected to mouth; The 4-slip joint.
Embodiment
Embodiment, with reference to accompanying drawing, concrete prefabricated square tube is formed by mouth 3 by body 2, cone-shaped plug 1 and taper, is characterized in establishing one section slip joint 4 in the middle of the body 2, body 2 sections are made square, and the taper of during assembling the cone-shaped plug 1 of body 2 being inserted another body is subjected in mouthfuls 3.Then, with the interface casting resin connection mouth filling between two pipes is coupled together.
Concrete prefabricated square tube has wide range of applications, and is that intensity height, scientific strong city municipal engineering are generally adopted in present flourishing city as the underground pipe gallery (common trench) in city, also is that China firmly builds the technological project that portion's Eleventh Five-Year Plan emphasis is promoted; Also can be applicable in addition in closed conduit and section big vast canal, pipe network of draining and highway, railway, culvert and the electric power tunnel.
Claims (1)
1, a kind of concrete prefabricated square tube is formed by mouthful (3) by body (2), cone-shaped plug (1) and taper, it is characterized in that establishing one section slip joint (4) in the middle of the body (2), and body (2) section is made square.
