At present, in municipal pipe laying engineering, there are generally two ways now: one is an open type large excavation mode, namely the ground can be excavated completely, pipes are sleeved with each other, connected and placed down, and then backfilling is carried out, the pipes required by the mode are prefabricated, and the pipes do not bear pressure or jacking force during connection and laying, so that the construction is simple and convenient; another way is when the pipeline cannot be laid by a large excavation method due to the limitation of specific environments such as buildings and the like, only a working pit is pre-excavated, and when the working pit works, a section of the pipe is pushed forwards and passes through a position with a certain depth underground, the working environment needs the end part of the pipe to be provided with a pipe jacking part, and the connection between the pipes is sealed and connected through a lantern ring.

In order to be connected with each other, the two ends of the existing jacking pipe are provided with concave platforms, steel lantern rings are arranged in the concave platforms, and two adjacent jacking pipes are connected through the steel lantern rings. The utility model discloses a be CN 200975561Y's utility model patent discloses a glass steel sanded push pipe, its engineering in underground construction, the tube tail of preceding glass steel sanded push pipe docks with the tube head of the next glass steel sanded push pipe to establish a glass steel pipe at the partial cover of the tube head and the tube tail of butt joint, and establish the sealing washer on the recess of tube head and tube tail, thereby seal the coupling part of two push pipes. But one of the problems is that an additional glass fiber reinforced plastic pipe is required, increasing the installation process. The second problem is that because the outer diameters of the pipe head and the pipe tail can not be guaranteed to be completely consistent in the production process of the jacking pipe, a large gap is often formed between the outer walls of the sleeve ring and the pipe head and the pipe tail, and even if the adopted sealing ring is used for sealing, the leakage of liquid in the jacking pipe to the outside of the jacking pipe through the gap is still difficult to avoid.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides a novel glass steel ejector sleeve joint structure, includes the push pipe body that uses the resin to make as base member, glass fiber as reinforcing material, locate push pipe body both ends and with push pipe body integrated into one piece's tube head and pipe tail, the outer wall of tube head outwards extends along push pipe body axial and forms the pipeline bellmouth, the inner wall of pipe tail outwards extends along push pipe body axial and forms the pipeline socket, the pipeline socket is pegged graft in the pipeline bellmouth of adjacent push pipe body, the tip of tube head is equipped with the liner in pipeline bellmouth inboard, when the pipeline socket is pegged graft in the pipeline bellmouth, the tip and the liner butt of pipeline socket, the outer wall of pipeline socket is equipped with an annular groove at least, be equipped with the rubber circle in the annular groove.

Further improved, a chamfer is arranged on one end, far away from the top pipe body, of the inner wall of the pipeline bellmouth.

Further improved, the joint of the pipeline socket and the pipe jacking body is provided with an inclined plane matched with the chamfer of the pipeline socket.

The improved structure of the pipe jacking device is characterized in that the outer diameter of the pipe bellmouth is larger than that of the pipe jacking body, and the outer wall of the pipe bellmouth extends towards one end of the pipe jacking body to the middle of the pipe jacking body to form a reinforcing part.

By adopting the technical scheme, the utility model has the beneficial effects that: 1. the steel lantern ring is omitted, the liquid in the pipe is prevented from leaking in two directions, and when the pipe socket is installed, after the pipe socket is connected with the pipe socket through the rubber ring, the interface pressure test can be carried out on site, and the sealing performance of the interface is tested; 2. by arranging the gasket, the effect of improving the connection sealing performance between the adjacent jacking pipes is achieved, so that the sealing performance is greatly improved; 3. the chamfer angle is arranged on the pipe socket, so that the pipe socket can be conveniently inserted into the pipe socket; 4. through setting up the rib, increased the stability of being connected of tube head and pipeline bellmouth.
