[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a pipe jacking construction device for complex geology.

[0035] Reference Figure 1A pipe jacking construction device for complex geological conditions comprises a base 1, the top of the base 1 is fixedly connected to a wall 2, one side of the wall 2 is fixedly connected to a support plate 3, one side of the support plate 3 is fixedly connected to a jack 4, the output end of the jack 4 is fixedly connected to a push plate 5, one side of the push plate 5 is evenly provided with a plurality of limit grooves, and the limit grooves are all installed with limit components 6, the top of the base 1 is fixedly connected to a guide seat 7, the top of the guide seat 7 is provided with a groove, the groove is installed with a guide component 8, a jacking pipe 9 is arranged on the top of the guide seat 7, one end of the jacking pipe 9 is rotatably connected to a turntable 10, the front end of the turntable 10 is evenly fixedly connected to a plurality of drill bits 11, the wall 2 is fixedly connected to a fixed plate 13, and one side of the fixed plate 13 is installed with a water spray component 17.

[0036] When in use, first place the jacking pipe 9 on the guide seat 7 by a crane, then fit one end of the jacking pipe 9 tightly with one side of the push plate 5, and then start the limit assembly 6 to fix the inner wall of the jacking pipe 9 by the limit assembly 6. After the fixation is completed, start the jack 4 to push the push plate 5 forward, so that the jacking pipe 9 is pushed forward together with the movement of the push plate 5. According to the guiding fixation of the limit assembly 6 and the guide seat 7, the jacking position of the jacking pipe 9 will not be offset during the jacking process, so as to prevent the jacking pipe 9 from deviating from the preset track and affecting the construction progress. When 9 moves on the guide seat 7, according to the guidance of the guide assembly 8, the top pipe 9 can move more smoothly and be pushed out into the geology better. Secondly, since there are some hard soils in the complex geology, the turntable 10 and the drill bit 11 can be started to rotate at this time, and the hard soil in front can be broken by multiple drill bits 11. At the same time, during the crushing process of the drill bit 11, the water spray assembly 17 can also be started to operate, and the soil in front can be sprayed with water by the water spray assembly 17, so that the soil is in a moist state, and the hard soil in front can be broken more conveniently and quickly, thereby improving the construction efficiency.

[0037] Reference Figure 1 and Figure 2 The limiting assembly 6 includes a fixing frame 61 fixedly connected to the limiting groove, a threaded rod 62 is rotatably connected inside the fixing frame 61, a motor 2 63 is fixedly connected inside the fixing frame 61, an output end of the motor 2 63 is fixedly connected to one end of the threaded rod 62, an arc plate 64 is threadedly connected to the threaded rod 62, a guide rod 65 is fixedly connected inside the fixing frame 61, one end of the arc plate 64 is slidably connected to the guide rod 65, and an anti-slip pad 66 is fixedly connected to one side of the arc plate 64.

[0038] When in use, first start the motor 2 63 to drive the threaded rod 62 to rotate. When the threaded rod 62 rotates, the arc plate 64 will move on the threaded rod 62 according to the guidance of the guide rod 65 until the arc plate 64 is tightly fitted with the inner wall of the jacking pipe 9. When multiple arc plates 64 are fitted to the inner wall of the jacking pipe 9, the jacking pipe 9 can be limited and fixed, so that when the jacking pipe 9 is pushed forward to be ejected, the position of the jacking pipe 9 will not be offset, thereby preventing the jacking pipe 9 from deviating from the preset track and affecting the construction progress. Secondly, the anti-slip pad 66 on one side of the arc plate 64 can increase the friction between the arc plate 64 and the jacking pipe 9 to prevent the arc plate 64 from sliding and falling off during the ejection process.

[0039] Reference Figure 1 and Figure 3 The guide assembly 8 includes a plurality of electric telescopic rods 81 uniformly and fixedly connected inside the groove, the tops of the plurality of electric telescopic rods 81 are fixedly connected with guide plates 82, the tops of the guide plates 82 are provided with limiting grooves, and a plurality of rotating rods 83 are rotatably connected inside the limiting grooves.

[0040] When in use, first start the electric telescopic rod 81 to drive the guide plate 82 to rise until the top of the guide plate 82 is in contact with the outer wall of the jacking pipe 9. The electric telescopic rod 81 can be used to guide and limit the bottom of the jacking pipe 9 to prevent the jacking pipe 9 from moving randomly during the jacking process. The rotating rod 83 inside the guide plate 82 can make the jacking pipe 9 move more smoothly and be better pushed into the geology.

[0041] Reference Figure 1 and Figure 4 A plurality of through holes 12 are evenly arranged on the drill bit 11, a motor 14 is fixedly connected to one side of the fixing plate 13, a rotating column 15 is rotatably connected to the other side of the fixing plate 13, an output end of the motor 14 is fixedly connected to the rotating column 15, a plurality of fixed columns 16 are fixedly connected to one side of the rotating column 15, and one end of the fixed column 16 is fixedly connected to one side of the turntable 10.

[0042] When in use, first start the motor 14 to drive the rotating column 15 to rotate. Through the rotation of the rotating column 15, the fixed column 16 drives the turntable 10 to rotate together, thereby driving the multiple drill bits 11 on one side of the turntable 10 to rotate at high speed. Through the rotation of the multiple drill bits 11, the hard soil in front is broken, so that the jacking pipe 9 can be better pushed forward. At the same time, the broken soil layer can enter the inside of the jacking pipe 9 through the through hole 12 and wait for discharge.

[0043] Reference Figure 1 and Figure 5The water spray assembly 17 includes a water tank 171 fixedly connected to one side of the fixed plate 13, a pump 172 is fixedly connected to the top of the water tank 171, a pumping pipe 173 is fixedly connected to the output end of the pump 172, one end of the pumping pipe 173 is fixedly connected to a connecting frame 174, and a plurality of high-pressure nozzles 175 are evenly and fixedly connected to the connecting frame 174.

[0044] When in use, the pump 172 can be started to pump out the water inside the water tank 171, and the pumped water is collected into the connecting frame 174 through the pumping pipe 173, and then sprayed out through multiple high-pressure nozzles 175. The sprayed water can not only flush the through hole 12 on the drill bit 11 to avoid blockage, but also spray the water into the soil in front through the through hole 12, so that the soil is in a moist state, and the hard soil in front can be broken more conveniently and quickly, thereby improving construction efficiency.

[0045] The implementation principle of the pipe jacking construction device for complex geological conditions in this embodiment is as follows: when in use, firstly, the jacking pipe 9 is placed on the guide seat 7 by a crane, and then one end of the jacking pipe 9 is closely fitted with one side of the push plate 5, and then the motor 2 63 is started to drive the threaded rod 62 to rotate. When the threaded rod 62 rotates, the arc plate 64 moves on the threaded rod 62 according to the guidance of the guide rod 65 until the arc plate 64 is closely fitted with the inner wall of the jacking pipe 9;

[0046] When the plurality of arc plates 64 are attached to the inner wall of the jacking pipe 9, the jacking pipe 9 can be limited and fixed, so that when the jacking pipe 9 is pushed forward, the position of the jacking pipe 9 will not be offset, so as to prevent the jacking pipe 9 from deviating from the preset track and affecting the construction process. Secondly, the anti-skid pad 66 on one side of the arc plate 64 can increase the friction between the arc plate 64 and the jacking pipe 9, so as to prevent the arc plate 64 from sliding and falling off during the ejection process. When the fixing is completed, the jack 4 is started to push the push plate 5 forward to eject, so that the jacking pipe 9 is ejected forward together with the movement of the push plate 5.

[0047] At the same time, when pushing the top pipe 9 to move on the guide seat 7, the electric telescopic rod 81 can be started to drive the guide plate 82 to rise until the top of the guide plate 82 fits the outer wall of the top pipe 9. The bottom of the top pipe 9 can be guided and limited by the electric telescopic rod 81 to prevent the top pipe 9 from moving randomly during the jacking process. The rotating rod 83 inside the guide plate 82 can make the top pipe 9 move more smoothly and better push it into the geology.

[0048] In addition, since there are some hard soils in complex geology, the motor 14 can be started to drive the rotating column 15 to rotate. Through the rotation of the rotating column 15, the fixed column 16 drives the turntable 10 to rotate together, thereby driving the multiple drill bits 11 on one side of the turntable 10 to rotate at high speed. Through the rotation of the multiple drill bits 11, the hard soil in front is broken, so that the top pipe 9 can be better pushed forward. At the same time, the broken soil layer can enter the top pipe 9 through the through hole 12 and wait for discharge. At the same time, during the crushing process of the drill bit 11, the pump 172 can also be started to operate to extract the water source in the water tank 171. The extracted water source is merged into the connecting frame 174 through the suction pipe 173, and then sprayed through multiple high-pressure nozzles 175. The sprayed water source can not only flush the through hole 12 on the drill bit 11 to avoid blockage, but also spray the water source into the soil in front through the through hole 12, so that the soil is in a moist state, and the hard soil in front is more convenient and quick to crush, thereby improving construction efficiency.
