Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking engineering, in particular to an anti-settling pipe jacking machine used in pipe jacking engineering for crossing a river. Background Art

[0002] In the pipe jacking project, the anti-settling pipe jacking machine is a mechanical device specially used for pushing and installing the pipe jacking. It is mainly used to overcome the problems of soft riverbed soil and liquefaction, and ensures that the pipe jacking will not settle or sink when crossing the riverbed by providing stable support, dispersing loads, controlling the propulsion speed, monitoring soil changes and improving work efficiency, and ensures the safety and quality of the construction.

[0003] However, when workers usually use it, the cutter disc only squeezes or breaks up the silt. The silt is usually composed of particles of different sizes, such as fine particles and larger particles. Some of the fine particles will gather together to form larger particles due to surface tension and other reasons. It may not be possible to effectively break up these larger particles by just using the cutter disc to break up the silt, and thus it is impossible to fully destroy the structure of the silt. In the process of the cutter disc breaking up the silt, some fine particles may be squeezed between larger particles, causing the silt to re-agglomerate. In this case, even if the pipe jacking machine continues to advance, settling or sinking may occur. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provide an anti-settling pipe jacking machine for pipe jacking through river engineering.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-sinking pipe jacking machine for pipe jacking and river crossing engineering, comprising: a pipe jacking machine body, the pipe jacking machine body comprises an outer shell, an auxiliary mechanism is arranged on the outer surface of the outer shell, a cutter disc is arranged on one side of the inner wall of the outer shell, a bulldozer block is arranged on one side of the cutter disc, a detection channel is arranged on one side of the inner wall of the bulldozer block, a shift sensor is arranged on one side of the detection channel, a crushing bin is arranged on one side of the inner wall of the outer shell, two rotating rings are arranged on one side of the inner wall of the crushing bin, a plurality of crushing knife groups are arranged on one side of the inner wall of the two rotating rings, a storage shell is arranged on one side of the outer shell, a plurality of diverter plates are arranged on one side of the inner wall of the storage shell, and a plurality of slots opened on the outer surface of the storage shell are arranged on the inner wall of the mud discharge pipe.

[0006] As a preferred implementation, the auxiliary mechanism comprises a mounting ring, one side of the inner wall of the mounting ring is fixedly connected to the outer surface of the housing, and a plurality of guide blocks are fixedly connected to the outer surface of the mounting ring.

[0007] As a preferred implementation, one side of the inner wall of the shell is fixedly connected to one side of the cutter disc, and one side of the cutter disc is fixedly connected to one side of the bulldozer block.

[0008] As a preferred implementation, a detection channel is opened on one side of the inner wall of the bulldozer block, and the outer surface of the displacement sensor is fixedly connected to one side of the detection channel.

[0009] As a preferred implementation, the outer surface of the crushing bin is fixedly connected to one side of the inner wall of the outer shell.

[0010] As a preferred embodiment, the two chute openings on the inner wall of the crushing bin are both rotatably connected to a rotating ring, and one side of the inner wall of the two rotating rings is fixedly connected to a plurality of crushing knife groups.

[0011] As a preferred embodiment, one side of the storage shell is fixedly connected to one side of the mounting shell.

[0012] As a preferred embodiment, a plurality of diverter plates are fixedly connected to one side of the inner wall of the storage shell, and the inner walls of a plurality of slots opened on the outer surface of the storage shell are fixedly connected to mud discharge pipes.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] The utility model can quickly and effectively break up the soil and stones for a second time through the installed crushing chamber, rotating ring and crushing knife group. With the assistance of water flow, the crushing effect can be enhanced and the crushing efficiency can be improved. In the pipe jacking and river crossing project, the stability of the stratum is very important.

[0015] It can not only break the soil and gravel into smaller particles, reduce the resistance of the formation during the process of pushing the jacking pipe, and improve the stability of the jacking pipe; the rotating ring and the crushing knife group can also break the soil and gravel into smaller particles, making the soil easier to remove, and can also reduce the accumulation and blockage of soil during the jacking pipe crossing process, ensure the smooth advancement of the jacking pipe, reduce the load of the propulsion machinery, reduce the risk of equipment damage, and extend the service life of the equipment. At the same time, it can also improve the construction efficiency. Breaking the soil makes it easier to transmit the propulsion force, reduces the resistance of the jacking machine, and makes the propulsion speed faster, thereby shortening the construction period;

[0016] In the pipe jacking and river crossing project, the pipeline is long and the equipment will generate greater friction on the pipeline when it is pushed, which will lead to increased pipeline loss.

[0027] In this embodiment, a detection channel 14 is provided on one side of the inner wall of the housing 11 and a cutter disc 12, a cutter disc 12 and a bulldozer block 13, and a displacement sensor 15 is fixedly connected to one side of the inner wall of the bulldozer block 13; the displacement sensor 15 is installed on one side of the detection channel 14, which can not only monitor and record the displacement change of the bulldozer block 13 in real time.

Through the measurement of the displacement sensor 15, the displacement change of the bulldozer block 13 can also be obtained, including horizontal displacement or vertical displacement. These data can provide more accurate information, help analyze the operating status and efficiency of the system, and make corresponding adjustments and optimizations. The displacement sensor 15 can output the displacement data for subsequent data recording and analysis. By collecting and analyzing the displacement data, the displacement characteristics, change trends and other information of the bulldozer block 13 under different working conditions can be obtained, providing a basis for the optimization and improvement of the system.

[0028] The outer surface of the crushing chamber 16 is fixedly connected to one side of the inner wall of the shell 11, and two slide grooves opened on the inner wall of the crushing chamber 16 are rotatably connected to a rotating ring 17, and one side of the inner wall of the two rotating rings 17 is fixedly connected to a plurality of crushing knife groups 18; the crushing chamber 16 adopts a structure of multiple crushing knife groups 18, which can not only quickly and effectively break up the soil and stones for a second time, but also can enhance the crushing effect and improve the crushing efficiency through the assistance of water flow. In the jacking pipe crossing river project, the stability of the formation is very important.

Through the design of the storage shell 19 and the mud discharge pipe 111, the soil can also be effectively removed to reduce the risk of pipe blockage.

In the jacking pipe crossing the river project, the pipeline is long, and the equipment will generate a large friction force on the pipeline when advancing, thereby increasing the pipeline loss.

Usually, a hydraulic or electric pipe jacking machine is used as a drive to make the bulldozer 13 have limited contact with the mud surface, and then the blocky soil, sand and gravel are first dispersed by the cutter disc 12. The dispersed soil enters the crushing chamber 16 through the gap of the cutter disc 12 and the water flow. With the assistance of the water flow, the structure of multiple crushing knife groups 18 can quickly and effectively disperse the soil and stones for a second time.
