The invention is realized by the following technical scheme:
a prefabricated pipe gallery structure comprises a pipe gallery body, wherein one end of the pipe gallery body is a double-step rabbet, a first step is arranged at the bottom of the pipe gallery body, a second step is arranged at the top of the pipe gallery body, a groove is formed between the two steps, an annular rubber strip with double air bags is arranged in the groove, the two air bags are arranged in the middle of the rubber strip in parallel and extend along the circumferential direction of the rubber strip, one edge of the rubber strip is pre-arranged in the groove of the pipe gallery body, the air bags are filled in the groove, and the outward air bags are arranged outside the groove; the other side of the rubber strip is L-shaped, and the end part of the L-shaped side is abutted against the first step; the other end of the pipe gallery body is a three-step tongue-and-groove, and the middle step corresponds to the groove.
The both ends of piping lane body set up the split screw rod.
And grouting grooves are arranged on the inner walls of the two-step type rabbet and the three-step type rabbet.
The grouting groove is funnel-shaped.
The edge chamfer of the second step of the two-step type rabbet is an inclined plane, and the edge chamfer of the step of the three-step type rabbet corresponding to the inclined plane is an inclined plane.
Has the advantages that:
the prefabricated pipe gallery structure provided by the invention adopts the built-in double-air-bag rubber strip, so that the sealing property is good; the double-air-bag rubber strip is preset inside the pipe gallery body and is formed together with the pipe gallery body, compared with later-stage bonding, the double-air-bag rubber strip saves working procedures and is stable in structure; the prefabricated pipe gallery is simple in connection mode, construction environment is not limited by rainy days, and later maintenance is convenient.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings.
Example 1
A prefabricated pipe gallery structure is shown in figure 1 and comprises a pipe gallery body, wherein one end of the pipe gallery body is a two-step type groove and tongue 1, and the other end of the pipe gallery body is a three-step type groove and tongue 8. As shown in fig. 2 and 4, a first step 2 is arranged at the bottom of the pipe gallery body, a second step 3 is arranged at the top of the pipe gallery body, a groove 4 is arranged between the two steps, a rubber strip 5 with double air bags is arranged in the groove 4, the rubber strip 5 is annular, the two air bags are arranged in the middle of the rubber strip 5 in parallel and extend along the circumferential direction of the rubber strip 5, one side of the rubber strip 5 is fixedly arranged in the groove 4 of the pipe gallery body, namely, the rubber strip is embedded into the pipe gallery body in the prefabricating process of the pipe gallery body, the first air bag 6 is filled in the groove 4, and the outward second air bag 7 is arranged outside the groove 4; the other side of the rubber strip 5 is L-shaped, and the end part of the L-shaped side is propped against the first step 2. As shown in fig. 3 and 4, the other end of the pipe gallery body is a three-step rabbet 8, and the middle step 9 corresponds to the groove 4.
After connection, as shown in fig. 5, the three-step rabbet 8 corresponds to the two-step rabbet 1, and the two connected prefabricated pipe galleries are connected by bolts or split screws. The counter-pulling screw is prior art and is not described herein. Two gasbag rubber strips can be for providing conflict pressure, with the both ends in close contact with of piping lane body, when the difference in temperature arouses the contraction of piping lane body or inflation, the joint between the piping lane can self-adaptation be filled up to two gasbag homoenergetic. The step-like setting of tongue-and-groove can further effectively prevent water entering pipe gallery.
Example 2
