Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction facilities, and particularly relates to a receiving device for receiving a pipe jacking machine. Background Art

[0002] Pipe jacking construction is a pipeline laying construction technology with little or no excavation. By means of the jacking force generated by jacking equipment in a working pit, the friction between the pipeline and the surrounding soil is overcome, and the pipeline is jacked into the soil according to the designed gradient, and the soil is transported away. After one pipe is jacked into the soil layer, the second pipe is lowered and jacked continuously. Pipe jacking technology is widely used in the laying, replacement and repair of various pipelines under the conditions where excavation is not allowed or not feasible, such as crossing roads, railways, rivers, downtown areas, etc. Due to the advantages of low comprehensive cost, short construction period, small environmental impact, good construction safety, etc., pipe jacking construction technology is widely used in the construction of underground pipelines such as municipal water supply and drainage, communication cables, gas pipelines, and power cables.

[0003] During the use of the pipe jacking machine, since the rubber of the portal seal will turn outwards when the pipe jacking machine enters the receiving well, in some high water pressure environments, the groundwater pressure may cause the sealing effect to fail. Furthermore, phenomena such as collapse and water leakage may occur, and in severe cases, the entire pipe jacking project may fail.

[0004] Therefore, the existing technology needs to be improved. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that the sealing may fail when the pipe jacking machine enters the receiving well. The purpose is to provide a receiving device for receiving a pipe jacking machine, which adopts corresponding technical means to enhance the sealing effect and prevent water leakage and sand gushing.

[0006] The utility model is realized by the following technical solutions:

[0007] The utility model provides a receiving device for receiving a pipe jacking machine, which includes a portal pipe installed at the receiving hole, a first receiving sleeve connected to the portal pipe, and a second receiving sleeve connected to the first receiving sleeve. A water stop ring for the pipe jacking machine to pass through is fixedly arranged on the inner wall of the first receiving sleeve. A pushing mechanism and a sealing ring which are connected to each other are arranged inside the first receiving sleeve. The cross section of the sealing ring is wedge-shaped. The pushing mechanism pushes the narrow end of the sealing ring into the gap between the water stop ring and the pipe jacking machine. A positive inclined surface which fits the surface of the sealing ring is arranged at the inner end of the water stop ring.

[0008] In the above technical solution, since the first receiving sleeve and the second receiving sleeve enclose the hole pipe, even if the hole pipe leaks, the water will only be stored inside the first receiving sleeve and the second receiving sleeve and will not flow into the receiving well, thus preventing the receiving well from being damaged. And when the pipe jacking machine moves into the first receiving sleeve and passes through the water stop ring and the sealing ring, the pushing mechanism pushes the left end of the sealing ring into the gap between the water stop ring and the pipe jacking machine. Due to the thrust applied by the pushing mechanism, it plays a role in plugging under pressure and achieves a better sealing effect.

[0009] Further, in the present utility model, the above-mentioned sealing ring is provided with a force-bearing plate, and the force-bearing plate is connected to the pushing mechanism.

[0010] Further, in the present utility model, the narrow end of the above-mentioned sealing ring is provided with an inclined surface facilitating the passage of the pipe jacking machine.

A support plate is fixedly arranged on the inner wall of the first receiving sleeve, and the pushing mechanism is fixedly connected to the support plate.

[0012] Further, in the present utility model, sliding strips for supporting the sliding of the pipe jacking machine are arranged inside the first receiving sleeve and the second receiving sleeve.

[0013] Further, in the present utility model, a sealing member is arranged at the connection between the hole pipe and the first receiving sleeve, and a sealing member is arranged at the connection between the first receiving sleeve and the second receiving sleeve.

[0014] Further, in the present utility model, the above-mentioned sealing member is configured as a rubber sealing member, the sealing ring is configured as a rubber sealing ring, and a support skeleton is arranged inside the rubber sealing ring.

[0015] Further, in the present utility model, both the first receiving sleeve and the second receiving sleeve include two semi-circular sleeves. A flange is arranged at the edge of the semi-circular sleeve, and a plug cover is hermetically connected to the tail end of the second receiving sleeve through a flange.

[0016] Further, in the present utility model, the above-mentioned plug cover is provided with a reinforcing angle steel, the reinforcing angle steel is connected with a support rod, and the support rod is fixedly connected to the receiving well.

[0017] Further, in the present utility model, reinforcing hoops for restricting deformation are arranged outside both the first receiving sleeve and the second receiving sleeve.

[0018] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0019] The utility model provides a receiving device for a pipe jacking machine, which includes a hole pipe, a first receiving sleeve and a second receiving sleeve. Since the first receiving sleeve and the second receiving sleeve enclose the hole pipe, even if the hole pipe leaks, the water will only be stored inside the first receiving sleeve and the second receiving sleeve and will not flow into the receiving well, thus preventing the receiving well from being damaged. And when the pipe jacking machine moves into the first receiving sleeve and passes through the water stop ring and the sealing ring, the pushing mechanism pushes the left end of the sealing ring into the gap between the water stop ring and the pipe jacking machine. Due to the thrust applied by the pushing mechanism, it plays a role of pressure sealing, achieving a better sealing effect and preventing phenomena such as collapse and water leakage of the receiving well.

[0033] Furthermore, a flange is provided at the right end of the hole pipe 1, and flanges are installed at both ends of the first receiving sleeve 2 and the second receiving sleeve 3. The left end flange of the first receiving sleeve 2 is butted against the flange of the hole pipe 1, and the two flanges are fixed by bolts, and an extruded seal 8 is inserted between the two flanges to enhance the sealing of the connection. Similarly, the right end flange of the first receiving sleeve 2 is butted against the left end flange of the second receiving sleeve 3, and the two flanges are fixed by bolts, and an extruded seal 8 is inserted between the two flanges to enhance the sealing of the connection. A plugging cover 301 is installed at the right end of the second receiving sleeve 3, and the plugging cover 301 is also connected to the right end of the second receiving sleeve 3 through a flange, and a seal 8 is inserted at the connection.

[0034] It should be noted that an anchoring agent is applied to the joint where the sealing member 8 is installed to enhance the sealing performance. The sealing member 8 is a rubber sealing member.

[0035] In some implementations of this embodiment, Figure 1 As described above, a reinforcing clamp 7 is installed on the outside of the first receiving sleeve 2 and the second receiving sleeve 3. The reinforcing clamp 7 tightens the periphery of the first receiving sleeve 2 and the second receiving sleeve 3, thereby increasing the periphery strength of the first receiving sleeve 2 and the second receiving sleeve 3, limiting deformation, and avoiding deformation damage accidents.

[0036] For further information, please refer to Figure 1 As shown, a reinforcing angle steel 302 is welded on the outer wall of the plug cover 301, and the reinforcing angle steel 302 is fixedly connected to the plug cover 301 in the form of a spoke distribution to increase the strength of the plug cover 301.
