Description

Technical Field

[0001] The utility model belongs to the technical field of pipe jacking correction, and particularly relates to a pipe jacking correction device. Background Art

[0002] Pipe jacking is increasingly being used in water supply and environmental management projects due to its adaptability and minimal impact on the surrounding environment. Pipe jacking is a trenchless construction method, a technique for laying pipes with minimal or no excavation. Because it minimizes environmental impact and eliminates the need for traffic disruption, it is increasingly being used in municipal pipe network construction, including those for stormwater and sewage systems and water supply and drainage systems.

[0003] Pipe jacking construction involves using the jacking force generated by jacking equipment within a working pit to overcome the friction between the pipe and the surrounding soil, pushing the pipe into the soil according to the designed slope, and then removing the soil. After one pipe section is pushed into the soil, the second section is lowered and continues jacking. During the jacking process, the soil quality surrounding the pipe jacking machine significantly affects the construction. In areas with quicksand or soft silt soil, the machine head is prone to sinking due to its poor bearing capacity, posing a significant construction risk and making it difficult to guarantee the quality of the pipeline construction. Typically, the pipe jacking machine head has good self-correction capabilities. However, if the sinking exceeds this capability, the machine head can only be removed through excavation or other methods. This method is extremely costly and increases the construction risk. Currently, there is a lack of a reliable and durable pipe jacking correction device to facilitate the leveling of the pipe jacking machine head to its original position.

[0004] Therefore, a new technology is needed to solve the problem that the prior art lacks a reliable and durable pipe jacking correction device. Utility Model Content

[0005] In order to solve the above problems in the prior art, the utility model provides a reliable and durable pipe jacking correction device, which can facilitate the leveling of the pipe jacking machine head to the original position.

[0006] The utility model adopts the following technical solutions:

[0007] A pipe jacking correction device includes a base, a first clip, a second clip and a driving device; the output shaft of the driving device is connected to the base; the first clip is arranged below the driving device; the second clip is arranged below the base; the first clip and the second clip can be installed at the alternating position between the pipe jacking machine head and the pipe section.

[0008] Furthermore, the driving device is a hydraulic cylinder; and the output shaft is a hydraulic telescopic rod.

[0009] Furthermore, the hydraulic telescopic rod can provide a maximum extension of 20 cm.

[0010] Furthermore, it also includes a fastener; the first buckle is fixed to the driving device through the fastener; the second buckle is also fixed to the base through the fastener.

[0011] Furthermore, the first buckle is provided with a plurality of first holes; the driving device is provided with a plurality of second holes; the fastener connects the first buckle and the driving device through the first holes and the second holes;

[0012] The second buckle is provided with a plurality of third holes; the base is provided with a plurality of fourth holes; the fastener connects the second buckle and the base through the third holes and the fourth holes.

[0013] Furthermore, the base includes a horizontally arranged flat plate, a vertically arranged upright plate and reinforcing ribs; the upright plate is arranged on the flat plate; and the reinforcing ribs connect the flat plate and the upright plate.

[0014] Furthermore, one end of the output shaft of the driving device is welded and fixed to the vertical plate.

[0015] Furthermore, the first buckle and the second buckle each include a straight plate portion and a hook plate portion; the hook plate portion is integrally connected to the straight plate portion.

[0016] Furthermore, the inner angle between the hook plate portion and the straight plate portion is 90°.

[0017] Furthermore, the vertical length of the hook plate portion is ≥15 cm; the top view length of the hook plate portion is 20 cm to 25 cm.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] During the pipe jacking construction process, if the pipe jacking machine head sinks beyond the maximum correction stroke (meaning it exceeds the self-correction capability of the pipe jacking machine head), the "pipe jacking correction device" of the present invention can be used to effectively level the pipe jacking machine head to its original position. The "pipe jacking correction device" of the present invention does not require pre-installation and only requires subsequent assembly. When the pipe jacking machine head is large in size and weight, and the surrounding soil pressure is enormous, and the correction load is large, multiple "pipe jacking correction devices" can be used simultaneously to complete the correction as quickly as possible. During deviation correction, the first clip and the second clip can be installed at the alternating position between the pipe jacking machine head and the pipe section (such as the gap between the pipe jacking machine head and the pipe section). After installation, the thrust generated by the driving device is used to correct the deviation so that the pipe jacking machine head is leveled to the original position as soon as possible; after the deviation correction is completed, the pipe jacking machine head returns to its original position, and the driving device is used to drive the output shaft to retract, and the first clip and the second clip are respectively separated from the effect on the "pipe jacking machine head and pipe section". Therefore, the "pipe jacking correction device" of the utility model can be quickly removed. BRIEF DESCRIPTION OF THE DRAWINGS
