Description

Technical Field

[0001] The invention relates to the technical field of pipeline construction, and in particular to a pipe jacking construction device and a construction process thereof. Background Art

[0002] Pipe jacking construction is a trenchless construction method that uses the jacking force generated by jacking equipment in the working pit to push the pipe into the soil according to the designed slope and pass through various obstacles to achieve pipe laying. This method has the advantages of no excavation or less excavation, strong adaptability, and no impact on traffic. It is widely used in urban drainage, power cable laying, and telecommunication pipeline installation.

[0003] In the process of placing and pushing the pipeline during pipe jacking construction, the traditional pipe jacking construction support system often adopts a support structure of fixed specifications, which is difficult to adapt to construction pipelines of different diameters and specifications. During pipe jacking construction, there are often differences in geological conditions, construction conditions and engineering requirements between different starting wells. As a result, in actual construction, it is often necessary to replace the entire support system according to the pipeline specifications, which not only increases the construction cost but also reduces the construction efficiency. In the face of complex and changeable geological conditions and construction environment, the traditional support system lacks sufficient flexibility and cannot adapt and adjust quickly, which limits the flexibility and efficiency of the construction process. At the same time, frequent replacement of the support system or adjustment of the pipeline position will also lead to extended construction time, increased costs, and reduced overall construction efficiency.

[0056] Embodiment 2 of the present invention:

[0057] The pipe jacking construction process includes the following steps:

[0058] Step 1: Construction preparation and equipment installation;

[0059] Step 2: Pipe jacking and pipeline laying;

[0060] Step 3: Post-processing and quality acceptance.

[0061] Step 1 includes: conducting geological survey and design of the construction area, preparing the equipment required for pipe jacking construction, including cylinder 3, pipe jacking machine, relay room, main jacking equipment, etc., and installing and debugging to ensure that the equipment is in good condition.

[0062] Step 2 includes: using the thrust devices such as the oil cylinder 3, the pipe jacking machine and the relay room to push the tool pipe or the tunnel boring machine from the starting well 1 through the soil layer to the arrival well, and at the same time, the pipeline following it is buried between the two pits to ensure that the pipeline is pushed forward along the designed axis.

[0063] Step three includes: After the pipe jacking construction is completed, the pipeline is connected, fixed and inspected, including the inspection of the position, slope and connection status, leakage test and pressure test to ensure that the construction quality meets the requirements, and the construction area is cleaned up to restore the original appearance of the ground.

[0064] The complete usage steps and working principle of the above embodiment are as follows:

[0065] The following is the working process of the adaptation support auxiliary mechanism 6 for adapting the construction pipeline and providing auxiliary support for the construction pipeline:

[0066] During the pipe jacking construction process, Figure 1 As shown, the pipeline is placed on the arc-shaped bottom supporting plate 611, and after the oil cylinder 3 is started and operated, the pressure equalizing ring 4 is pushed away from the oil cylinder 3 (i.e., toward the arc-shaped bottom supporting plate 611). At this time, the right side of the pressure equalizing ring 4 will contact the left surface of the pipeline. The pushing action of the oil cylinder 3 is used to make the pipeline move synchronously to the right (i.e., away from the pressure equalizing ring 4) on the arc-shaped bottom supporting plate 611. The pipe jacking machine is set on the right side of the departure well 1 (which is the prior art), and the pipeline will eventually be pushed to connect with the pipe jacking machine. In this way, the pipe jacking construction process is carried out, and the above contents are all common knowledge and will not be elaborated on in detail here.

[0067] Since there are differences in geological conditions, construction conditions and engineering requirements between different starting wells 1 during the pipe jacking construction process, the pipe specifications and sizes used will also be different. At this time, the staff can adapt and adjust the gap between the arc bottom support plates 611 on both sides according to the size of the construction pipe, such as Figure 2 , Figure 3 as well as Figure 4As shown, during operation, by starting the driving motor 603, the bidirectional reciprocating screw 605 fixedly connected to its output end can be driven to rotate synchronously in the first slide groove 604 opened on the top of the first fixed frame 601. Since the outer surface of the bidirectional reciprocating screw 605 is symmetrically threaded with the linkage block 609, when the bidirectional reciprocating screw 605 is driven to rotate, the two linkage blocks 609 on it can be synchronously driven to move closer or farther away by means of threaded connection, and a support column 610 is fixedly provided on the top of the linkage block 609, and an arc bottom support plate 611 is fixedly provided on the top of the support column 610, so when the linkage block 609 is rotated, the two linkage blocks 609 on it can be driven to move closer or farther away from each other. 09 When moving, under the connection of the support column 610, the arc bottom support plate 611 synchronously follows and moves closer or farther, so as to adapt to the specifications of the pipeline used in the construction, thereby realizing the adaptive auxiliary support for the construction pipeline, which can not only improve the support effect on the construction pipeline, but also be applicable to construction pipelines of different specifications without replacing the entire support system, greatly improving the flexibility and efficiency of construction, and the adapted arc bottom support plate 611 can fit the pipeline surface more closely, provide more uniform support force, reduce the shaking and deviation of the pipeline during movement, and thus enhance the stability of the support;

[0068] Since the support frame 5 is also symmetrically fixed with the first fixing frame 601 as the center, and the second fixing frame 606 has a second slide groove 607 at the top, and a limit slide bar 608 is fixed in the second slide groove 607, and the second fixing frame 606 is also slidably provided with a linkage block 609 in the same manner as the first fixing frame 601, and the linkage block 609 arranged in the second fixing frame 606 penetrates and slides through the outer surface of the limit slide bar 608, as shown in FIG. Figure 2 and Figure 4As shown, in the foregoing text, when the two-way reciprocating screw 605 rotates to drive the linkage block 609 on it to move synchronously toward or away from each other, the arc bottom support plate 611 connected to the linkage block 609 moves synchronously, and each linkage block 609 is fixedly connected to an arc bottom support plate 611 through a support column 610, and the same transverse arc bottom support plates 611 are fixedly connected through a through rod 612. Therefore, when the linkage block 609 set on the outer surface of the two-way reciprocating screw 605 moves, the same transverse arc bottom support plate 611 can be driven to move synchronously under the connection action of the support column 610 and the through rod 612. At this time, the linkage block 609 set on the outer surface of the limit slide 608 will synchronously move on the outer surface of the limit slide 608 The limiting slide bar 608 is used to limit the overall axial movement of the linkage block 609, thereby enhancing the stability of the arc bottom support plate 611 when it moves. The arc bottom support plate 611 can be provided with a gap between two adjacent arc bottom support plates 611 in the same horizontal direction by the setting of the through rod 612. When the pipeline is placed, the upper surface of the arc bottom support plate 611 will fit the outer surface of the pipeline. The design of the gap can reduce the contact area between the arc bottom support plate 611 and the pipeline while the arc bottom support plate 611 provides support for the pipeline, thereby reducing the friction and resistance generated during the movement of the pipeline, thereby helping to reduce the force required to push the pipeline and improving the efficiency and smoothness of the jacking construction.

[0069] Please refer to the above working process Figures 1 to 7 .

[0070] The following is the working process of the pipe jacking deviation testing mechanism 7 for detecting whether there is deviation in the pipe jacking path of the construction pipeline:

[0071] When the oil cylinder 3 drives the pressure equalizing ring 4 to move and push the pipe to connect with the pipe jacking machine, Figure 1 , Figure 5 , Figure 6 as well as Figure 7As shown, since the end of the support frame 5 away from the oil cylinder 3 is fixedly provided with a third fixing frame 702, and the third sliding groove 703 is provided on the top of the third fixing frame 702, and the first slide plate 704 is symmetrically slidably provided in the third sliding groove 703, when the linkage block 609 moves to synchronously drive the support column 610 to move, an L-shaped traction rod 701 is fixedly provided between the support column 610 arranged near the third fixing frame 702 and the first slide plate 704, so that as the support column 610 moves, the first slide plate 704 can be driven to move synchronously in the third sliding groove 703. The first slide plate 704 slides in accordance with the present invention. As the first slide plate 704 is fixedly provided with an L-shaped support plate 705 on the top, a follower rod 709 is symmetrically penetrated and slidably provided on the upper end of the L-shaped support plate 705, and a fourth slide groove 706 is provided on the inner wall of the lower end of the L-shaped support plate 705. A second slide plate 707 is slidably provided in the fourth slide groove 706, and one side of the second slide plate 707 is fixedly connected to the follower rod 709, and the other side of the second slide plate 707 is fixedly connected to the arc-shaped test plate 708. When the L-shaped traction rod 701 moves synchronously to drive the first slide plate 704 to slide in the third slide groove 703, as shown in FIG. Figure 5 As shown, through the connection of the first slide plate 704, the L-shaped support plate 705 can be driven to move synchronously, thereby increasing or decreasing the distance between the two arc-shaped test plates 708, so as to adapt to the current pipe specifications used, so that the pipe can move normally through this gap, as shown in FIG. Figure 6 and Figure 7As shown, since a return spring 710 is symmetrically fixedly arranged between the second slide plate 707 and the L-shaped support plate 705, and the return spring 710 is sleeved on the outer surface of the follower rod 709, if there is a deviation path during the process of the pipeline being pushed, the pipeline will cause the arc test plate 708 to be squeezed. The pressure on the arc test plate 708 will cause the follower rod 709 to penetrate the upper end of the L-shaped support plate 705 and move. At this time, the return spring 710 will also be compressed, and the return spring 710 arranged on the other side of the follower rod 709 will be compressed. The pressure plate 711 fixedly connected between the two ends will also be pushed out synchronously and move in the direction away from the L-shaped support plate 705. Since the first contact 712 is set on the pressure plate 711 and the second contact 713 is set on the L-shaped support plate 705, and the first contact 712 and the second contact 713 are in contact with each other at the beginning (that is, when the pipeline path is not offset), the warning indicator light 714 remains in the off state. When the pressure plate 711 moves, the first contact 712 and the second contact 713 lose contact. At this time, the warning indicator light 714 on this side will change from the off state to the on state, providing an intuitive warning signal for the staff. The staff can judge whether there is any deviation in the pushing path of the pipeline during the jacking construction process according to the state of the warning indicator light 714, so as to find the abnormality of the pipeline in the first time and deal with it, so as to avoid long-term deviation affecting the overall jacking construction process. In the above process, by real-time monitoring of the deviation of the pipeline pushing path, it is helpful for the staff to better control the construction quality. Once the deviation is found, the construction parameters can be adjusted immediately or other corrective measures can be taken to ensure that the pipeline is pushed according to the predetermined path and posture, thereby improving the accuracy and precision of the construction, so that the staff can focus more on the construction process itself without having to frequently check whether the pipeline is offset. When the warning indicator light 714 is on, the staff can quickly locate the problem and take corresponding countermeasures, thereby optimizing the construction process and reducing unnecessary inspection and adjustment time.
