The utility model discloses a prefabricated concrete drain pipe can guarantee to connect between the interface and reach the requirement of existing standard, design drawing, effective stagnant water and improve the firm degree of drain pipe, simple structure, convenient operation.

Description

Prefabricated concrete drain pipe in sealing connection

Technical Field

The utility model belongs to the technical field of the drain pipe construction, a sealing connection's prefabricated concrete drain pipe that especially municipal works used.

Background

With the development of urban construction industry, municipal engineering construction is increasing day by day, and municipal drainage systems are main contents and important links in which matched construction is necessary. The drainage engineering comprises two categories of rainwater engineering and sewage engineering.

At present, the drain pipe generally adopts rigidity, flexible interfaces such as plain end, bell and spigot, steel ring, and the drainpipe can't be connected fast, portably to traditional interface, and the stagnant water effect is very brief, runs into earth and sinks then very easily to be out of shape, leads to the drain pipe to produce under the effect of water pressure behind the slope and oozes water, the water leakage phenomenon, and road bed earth can be taken away to the flowing water, and then leads to road surface to sink and form the pot hole after forming, produces danger. Therefore, it is necessary to research a precast concrete drain pipe which can effectively stop water and is firmly connected and filled with a rubber sealing ring interface.

SUMMERY OF THE UTILITY MODEL

The to-be-solved problem of the utility model is to provide a fill prefabricated concrete drain pipe of rubber seal interface can guarantee to connect the requirement that reaches current standard, design drawing between every section of drain pipe, effective stagnant water and the firm degree that improves the interface, simple structure, convenient operation.

The utility model discloses solve above-mentioned technical problem with following technical scheme:

a groove is arranged at the end opening of the prefabricated concrete drain pipe along the circumference, when two sections of the prefabricated concrete drain pipes are connected, the two corresponding grooves surround a circular channel, a rubber pipe is arranged in the circular channel, and concrete is filled in the rubber pipe.

Two ports of the rubber tube extend out of the groove, and one port of the rubber tube is used for grouting.

The cross section of the groove is semicircular. The cross section of the groove is semicircular.

The utility model has the advantages as follows:

the utility model discloses the drain pipe can guarantee to connect between the interface and reach the requirement of current standard, design drawing, effective stagnant water and improve the firm degree of drain pipe, simple structure, convenient operation.

Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings, but not limited to the scope of the present invention.

As shown in fig. 1 to 4, the prefabricated concrete drain pipe is hermetically connected, and a groove a2 is formed at the port of the prefabricated concrete drain pipe a1 along the circumference. The cross section of the groove a2 is semicircular. When the two sections of precast concrete drain pipes are connected, the port grooves a2 of the first section of drain pipe 3 and the second section of drain pipe 4 are correspondingly combined into a circular channel, a rubber pipe a3 is arranged in the circular channel, two ports of the rubber pipe extend out of the circular channel, the first port 1 of the rubber pipe is used for grouting, the second port 2 of the rubber pipe is used for ventilation, concrete a4 is filled into the rubber pipe a3 from the first port 1 of the rubber pipe, and the circular channel is completely filled after the rubber pipe a3 is expanded, so that the two sections of precast concrete drain pipes are hermetically connected.

The utility model relates to a sealing connection's prefabricated concrete drain pipe uses the construction steps in drainage engineering:

first, preparation of the previous stage

1. Before the construction of the drainage pipes is started, the installation plan of each drainage pipe should be planned in advance.

2. Preparation, submission, examination and approval of various construction materials and data.

(II) construction steps:

1. and (6) surveying the terrain again. 2. And (4) leveling the field. 3. And (5) lofting the pipe position. 4. The excavator is in position. 5. And digging a groove. 6. Hanging into a drain pipe. 8. And (5) installing a drain pipe. 9. And (6) pouring the pipe base. 10. And (5) performing later maintenance. 11. And (5) engineering detection. 12. And (5) checking and accepting the project.

The utility model discloses prefabricated concrete drain pipe is applied to 8 th step, and concrete mounting method is as follows:

1. the port grooves a2 of the first section of the water discharge pipe 3 and the second section of the water discharge pipe 4 are correspondingly combined into a circular channel, and a rubber pipe a3 is arranged in the circular channel;

2. the first rubber tube port 1 of the inserted rubber tube a3 is pressed with grout, the second rubber tube port 2 is ventilated, so that concrete grout fills the interior of the rubber tube a3, and the rubber tube a3 is expanded to completely fill the circular groove.

3. According to the procedure, the installation of each section and each section of the drainage pipe is completed.
