Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to a deviation correcting device for pipe jacking construction. Background Art

[0002] Pipe jacking is a trenchless construction method, that is, a pipeline burial construction technology with no excavation or less excavation. Pipe jacking is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the soil away. The principle is to use the thrust of the main jacking cylinder and the pipeline room, relay room, etc. to push the tool pipe or tunnel boring machine from the working pit through the soil layer to the receiving pit and lift it up. The pipeline follows the tool pipe or tunnel boring machine and is buried between the two pits. During the process of pipe jacking, the direction of the pipeline may deviate, so a device is needed to assist in correcting the deviation of pipe jacking construction. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a deviation correction device for pipe jacking construction, which effectively solves the deficiencies of the prior art.

[0004] The purpose of the utility model is achieved through the following technical scheme: a deviation correction device for jacking pipe construction, including a jacking pipe sleeve, a slide groove is opened on the inner side of the jacking pipe sleeve, sliders are slidably connected to both sides of the slide groove, the inner side of the slider is fixedly connected to a limiting ring, the outer side of the slider is fixedly connected to a seesaw, the outer side of the seesaw is fixedly connected to a steel wire rope, and the steel wire rope passes through the limiting ring.

[0005] Optionally, the jacking sleeve is sleeved on the front end of the pipe in the jacking construction, and the inner shape of the jacking sleeve is matched with the end shape of the pipe.

[0006] The above technical solution is adopted: by putting a jacking sleeve on the front end pipe of the jacking construction, the part where the end of the pipe contacts the soil can be protected, reducing the damage of the end pipe during the jacking construction, and when the jacking construction deviates, the steel wire ropes on both sides are pulled to act on the jacking sleeve and even the front end pipe, and its jacking direction can be slightly corrected.

[0007] Optionally, a contraction groove is provided at the front end of the outer side of the top pipe sleeve, the shape of the contraction groove is matched with the shape of the seesaw, and the seesaw is contracted inside the contraction groove.

[0008] The above technical solution is adopted: by setting a shrinkage groove on the outside of the jacking sleeve, the seesaw can be retracted in the shrinkage groove to avoid affecting the normal jacking of the pipeline during the jacking construction. When the jacking direction needs to be corrected, the wire rope in the corresponding direction is pulled, and the seesaw in the corresponding direction is pulled outward to generate a force with the soil layer, so that the jacking direction of the jacking pipe is offset to the other side, so that the tilted seesaw is used to assist in correcting the direction of the jacking pipe.

[0009] Optionally, the seesaw is made of alloy spring steel, and the seesaw is located inside the contraction groove in a normal state.

[0010] The above technical solution is adopted: by setting the seesaw to alloy spring steel so that it has excellent elasticity, after the correction wire rope is released from pulling, the seesaw can be reset and retracted into the shrinkage groove again, so that the seesaw can be reused, avoiding the seesaw being difficult to reset after being pulled, affecting the progress and accuracy of subsequent pipe jacking construction.

When the jacking pipe and the jacking sleeve rotate during the jacking construction process, the two sliders can remain horizontally located on both sides of the jacking pipe under the action of the gravity block, which is convenient for pulling the wire rope to correct the direction of the jacking pipe when the jacking pipe is offset.

[0013] Optionally, the length of the steel wire rope is greater than the total stroke of the jacking pipe construction, the diameter of the steel wire rope is smaller than the inner diameter of the limiting ring, and the friction coefficient between the steel wire rope and the limiting ring is less than 0.5.

[0014] The above technical solution is adopted: by limiting various parameters of the wire rope, one end of the wire rope can be kept outside the jacking tunnel during the jacking construction process, so that when the jacking construction is offset, the construction personnel can use a machine or manual pulling of the wire rope to correct the direction of the jacking construction by using the pulling force and the force of the raised seesaw on the soil layer.

[0015] The utility model has the following advantages:

[0016] 1. The correction device for pipe jacking construction can protect the part where the end of the pipe contacts the soil by sleeve-fitting the pipe jacking sleeve on the front end pipe of the pipe jacking construction, thereby reducing the damage of the end pipe during the pipe jacking construction. When the pipe jacking construction deviates, the steel wire ropes on both sides can be pulled to slightly correct the pipe jacking direction when the pipe jacking sleeve or even the front end pipe is exerted. By arranging a contraction groove on the outer side of the pipe jacking sleeve, the seesaw can be contracted in the contraction groove during the pipe jacking construction to avoid affecting the normal jacking of the pipe. When it is necessary to correct the direction of the pipe jacking, the steel wire rope in the corresponding direction is pulled, and the seesaw in the corresponding direction is pulled outward to generate a force with the soil layer, so that the jacking direction of the pipe jacking is deviated to the other side, so that the tilted seesaw is used to assist in correcting the direction of the pipe jacking.

[0017] 2. The correction device for pipe jacking construction has excellent elasticity by setting the seesaw plate to alloy spring steel. After the correction wire rope is released from pulling, the seesaw plate can be reset and retracted into the shrinkage groove again, so that the seesaw plate can be reused, avoiding the difficulty of resetting the seesaw plate after being pulled, affecting the progress and accuracy of subsequent pipe jacking construction.

[0018] 3. The correction device for pipe jacking construction has a connecting ring arranged between the sliders so that the two sliders are connected to each other and are respectively located on both sides of the pipe jacking sleeve. Under the action of the gravity block, the gravity block is located at the bottom of the inner side of the pipe jacking sleeve, and the two sliders are respectively located on both sides of the inner wall of the pipe jacking sleeve. When the pipe jacking pipe and the pipe jacking sleeve rotate during the pipe jacking construction process, the two sliders can remain horizontally located on both sides of the pipe jacking under the action of the gravity block, so that when the pipe jacking deviates, the steel wire rope is pulled to correct the deviation of the pipe jacking direction. By limiting various parameters of the steel wire rope, one end of the steel wire rope can be kept outside the pipe jacking tunnel during the pipe jacking construction process, so that when the pipe jacking construction deviates, the construction personnel can use a machine or manually pull the steel wire rope, and use the tension and the force of the tilted seesaw on the soil layer to correct the deviation of the pipe jacking construction direction.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The correction device for pipe jacking construction can protect the part where the end of the pipe contacts the soil by sleeve-fitting the pipe jacking sleeve 1 on the front end pipe of the pipe jacking construction, thereby reducing the damage of the end pipe during the pipe jacking construction. When the pipe jacking construction deviates, the steel wire ropes 6 on both sides can be pulled to slightly correct the pipe jacking direction when the pipe jacking sleeve 1 or even the front end pipe is exerted. By arranging a contraction groove 7 on the outer side of the pipe jacking sleeve 1, the seesaw 5 can be contracted in the contraction groove 7 during the pipe jacking construction to avoid affecting the normal jacking of the pipe. When it is necessary to correct the direction of the pipe jacking, the steel wire rope 6 in the corresponding direction is pulled, and the seesaw 5 in the corresponding direction is pulled outward to generate a force with the soil layer, so that the jacking direction of the pipe jacking is deviated to the other side, so that the tilted seesaw 5 is used to assist in correcting the direction of the pipe jacking.

[0037] 2. The correction device for pipe jacking construction has excellent elasticity by setting the seesaw 5 to alloy spring steel. After the correction wire rope 6 is released from pulling, the seesaw 5 can be reset and retracted into the retraction groove 7 again, so that the seesaw 5 can be reused, avoiding the difficulty of resetting the seesaw 5 after being pulled, which affects the progress and accuracy of subsequent pipe jacking construction.

By limiting various parameters of the steel wire rope 6, one end of the steel wire rope 6 can be kept outside the jacking tunnel during the jacking construction process, so that the construction personnel can use a machine or manually pull the steel wire rope 6 when the jacking construction deviates, and use the tension and the force of the tilted seesaw 5 on the soil layer to correct the deviation of the jacking construction direction.
