Abstract
The utility model discloses a prestressed reinforced concrete manhole pipe, comprising a concrete cylinder main pipe and a manhole branch pipe. The concrete cylinder main pipe comprises: a thin steel cylinder; a reinforcing steel pipe sheathed around and fixed with the thin steel cylinder and provided with a manhole orifice; a branch pipe casing sealed and fixed on the wall of the manhole orifice of the reinforcing steel pipe; a concrete layer wrapped around the thin steel cylinder, the reinforcing steel pipe and the branch pipe casing; a prestressed steel wire wound around the concrete layer; and a mortar coverage wound around the prestressed steel wire. The internal and external walls of the man-hole branch pipe are provided fixedly with steel wire mesh tablets, wherein the steel wire mesh tablets are fixed with the mortar coverage. When field installation is performed, the manhole branch pipe is sealed and fixed in the branch pipe casing of the concrete cylinder main pipe. The utility concrete cylinder main pipe and the manhole branch pipe are in separate structures and are fixed with each other only when performing field installation, which makes assembly and transport convenient. Besides, the external pressure bearing capacity is obviously enhanced and the service life is obviously lengthened.
Description
One, technical field:
The utility model belongs to water supply line and uses the manhole pipe.
Two, background technique:
In the water supply line, particularly electric power plant circulating water pipe-line system of long distance, often manhole need be set, so that in time pipeline is checked.Existing manhole pipe be the steel-made manhole pipe, be by the person in charge's steel pipe that steel plate is rolled, is welded into by plate bending rolls and manhole arm assembly welding together after, preservative treatment formation is carried out on its surface.The shortcoming of this steel-made manhole pipe is: 1. it only depends on steel itself to bear the external pressure load, and the external pressure load that bears is low; 2. anticorrosive coat is impaired easily when installing, and working life was short, less than 50 years; 3. it is subjected to the easy super wide or superelevation of influence of manhole arm when transportation, when mounted, owing to be subjected to the influence of manhole arm, and not easy to operate when lifting and installation; In a word, its transportation and installation are all inconvenient.
Three, summary of the invention:
The utility model is exactly to solve now with the problems referred to above that exist in the technology, and a kind of external pressure load height that bears is provided, and anticorrosive coat is difficult for impaired, the prestress steel cylinder concrete manhole pipe who easily installs and transport.
For addressing the above problem, technical solution of the present utility model is: a kind of prestress steel cylinder concrete manhole pipe, it comprises is responsible for and the manhole arm, the person in charge is that steel cylinder concrete is responsible for, it comprises thin steel cylinder, be enclosed within thin steel cylinder outer and with a pipe-in-pipe on the man-hole opening wall of strengthening steel pipe of together the reinforcement steel pipe that has man-hole opening of thin steel cylinder sealing and fixing, sealing and fixing, be wrapped in thin steel cylinder and strengthen the concrete layer on inside and outside wall of steel pipe and the arm sleeve outer wall and be wrapped in reinforcement wire outside the concrete layer and the mortar cover outside the reinforcement wire; Pipe-in-pipe is a steel pipe that is complementary with the man-hole opening internal diameter; The manhole arm is the steel pipe that the internal diameter of an external diameter and a pipe-in-pipe is complementary, it is except that being responsible for the weld bond of the underpart that is complementary and upper end portion with steel cylinder concrete of reserving, be fixed with steel fabric sheet on the inside and outside wall at all the other positions, steel fabric sheet is fixed with mortar cover; When installing at the scene, manhole arm sealing and fixing is in the pipe-in-pipe that steel cylinder concrete is responsible for.
The utility model has installed a pipe-in-pipe additional in steel cylinder concrete is responsible for, be two body structures before steel cylinder concrete being responsible for install at the scene with the manhole arm, during on-the-spot the installation, just the two is fixed together, and has made things convenient for and has installed and transportation.It relies on steel pipe, steel cylinder, interior outside concrete and reinforcement wire to combine and bears the external pressure load, and its stiffness significantly improves, and corresponding external pressure bearing capacity significantly improves, and its life-span phenomenal growth can reach 75 to 100 years.Mortar cover and reinforcement wire and concrete binding intensity height, the mortar cover difficult drop-off has also guaranteed its working life.
Four, description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is an internal structure schematic representation of the present utility model.
Five, embodiment:
As shown in Figure 1, present embodiment comprises the steel cylinder concrete person in charge and manhole arm 7.Steel cylinder concrete is responsible for and is comprised thin steel cylinder 4, reinforcement steel pipe 5, a pipe-in-pipe 6, concrete layer 3, reinforcement wire 2 and mortar cover 1.Strengthen the outside that steel pipe 5 is enclosed within thin steel cylinder 4, and weld together with the overlapping part of thin steel cylinder 4.Pipe-in-pipe 6 is a steel pipe that is complementary with the man-hole opening internal diameter of strengthening steel pipe 5, and it is welded on the man-hole opening wall of strengthening steel pipe 5.Be enclosed with concrete layer 3 on the inside and outside wall of thin steel cylinder 4 and reinforcement steel pipe 5 and on the outer wall of a pipe-in-pipe 6, the concrete layer 3 outer reinforcement wires 2 that are wound with, the reinforcement wire 2 outer mortar covers 1 that are bonded with.Strengthen steel pipe 5 outer fixing steel fabric sheet 10 is arranged.Manhole arm 7 is an external diameter and the internal diameter of a pipe-in-pipe 6 steel pipe that is complementary; it is except that being responsible for the weld bond of the underpart that is complementary and upper end portion with steel cylinder concrete of reserving; be fixed with steel fabric sheet 8 on the inside and outside wall at all the other positions, steel fabric sheet 8 outer fixing have mortar cover 9.When installing at the scene, manhole arm 7 is welded in the steel cylinder concrete person in charge's the pipe-in-pipe 6.
Claims (2)
1. prestress steel cylinder concrete manhole pipe, it comprises is responsible for and the manhole arm, it is characterized in that: the person in charge is that steel cylinder concrete is responsible for, it comprises thin steel cylinder, be enclosed within thin steel cylinder outer and with a pipe-in-pipe on the man-hole opening wall of strengthening steel pipe of together the reinforcement steel pipe that has man-hole opening of thin steel cylinder sealing and fixing, sealing and fixing, be wrapped in thin steel cylinder and strengthen the concrete layer on inside and outside wall of steel pipe and the arm sleeve outer wall and be wrapped in reinforcement wire outside the concrete layer and the mortar cover outside the reinforcement wire; Pipe-in-pipe is a steel pipe that is complementary with the man-hole opening internal diameter; The manhole arm is the steel pipe that the internal diameter of an external diameter and a pipe-in-pipe is complementary, it is except that being responsible for the weld bond of the underpart that is complementary and upper end portion with steel cylinder concrete of reserving, be fixed with steel fabric sheet on the inside and outside wall at all the other positions, steel fabric sheet is fixed with mortar cover; When installing at the scene, manhole arm sealing and fixing is in the pipe-in-pipe that steel cylinder concrete is responsible for.
