[0028] Example 2 Further illustrate with reference to Example 1, Figure 1-15The structure shown in FIG. 1 is applied with the construction method of the above-mentioned reverse construction method for the quick construction device for the shaft wall of a pipe jacking shaft, and the method comprises: S1, first build a steel cage 5 in the casting trough, then place the casting template 4 in the casting trough and apply a release agent on its outer surface, and then pour concrete to complete the first layer of the shaft; S2, then install the rotating assembly 1 at the edge of the first-level vertical shaft opening; S2.1 First, the rotating base 101 is arranged at the wellhead, and then the rotating top plate 102 is placed on the guide rail 106 so that the smooth wear-resistant layer 107 fits with each other; S2.2 Install the hook seat 108 on the outer side of the rotating top plate 102 so that the roller on the hook seat 108 fits with the lower side of the guide rail 106; S3, the lifting component 3 above the rotating component 1 is connected to the casting template 4 below; S3.1 Move the lifting rod 305 from below the lifting motor 309 to above the inner support frame 402, and connect the connecting sleeve 308 to the connecting seat 403; S3.2, when the length of the lifting rod 305 at the bottom is not enough, it is necessary to add a lifting rod 305 at the top; S4, then arrange the driving component 2 on one side of the rotating component 1; S4.1 The driving gear 204 in the driving assembly 2 is meshed with the rack portion 103, and the driving base 201 is fixed on the ground.
[0029] S5, continue to dig and build the steel cage 5. After the steel cage 5 is completed, start the driving assembly 2 to rotate the casting template 4 for demoulding; S5.1 Before the drive assembly 2 is started, the clamping cylinder 302 needs to be driven first to make the clamping claw 303 clamp the lifting rod 305, and then the drive motor 203 is started to rotate the casting template 4. When the next layer needs to be rotated, the drive motor 203 rotates the casting template 4 in the opposite direction to avoid the rack part 103 from completing its stroke. Each rotation only requires micro-movement demoulding; S6, after demoulding is completed, start the lifting component 3 to lower the casting template 4 to the next casting section; S7. Repeat steps S5-S6 to complete all pouring sections. After the final pouring is completed, the pouring template 4 is disassembled into blocks and then hoisted out of the shaft by the lifting assembly 3 to complete the shaft wall construction of the entire shaft.
[0030] The detailed steps of a construction method of a reverse pipe jacking shaft wall rapid construction device are as follows: In the casting trough, the longitudinal reinforcement is arranged first according to the requirements of the design drawings. The number, diameter and spacing of the longitudinal reinforcement must be determined strictly in accordance with the design specifications. The transverse reinforcement is arranged on the longitudinal reinforcement at a certain spacing, and the longitudinal reinforcement and the transverse reinforcement are connected into an integral reinforcement cage by tying or welding. During the construction process, tools such as the reinforcement positioning bracket are required to ensure the accurate position and uniform spacing of the reinforcement.
[0031] Carefully hoist the pre-assembled casting template 4 into the casting trough by lifting equipment, so that the center of the template is aligned with the center of the casting trough. When placing the template, care should be taken to avoid collision between the template and the steel cage, which may damage the steel cage or the template. After the template is in place, evenly apply a layer of release agent on the outer surface of the casting template 4. The choice of release agent should be reasonably selected according to the material of the template and the construction environment to ensure good demoulding effect without affecting the surface quality of the concrete.
[0032] Use concrete pumps and other equipment to deliver the mixed concrete to the pouring trough. During the pouring process, it should be carried out in accordance with the principle of layered pouring. After each layer of concrete is poured, use a vibrator to vibrate it to ensure that the concrete is dense and free of bubbles, so as to ensure that the upper and lower layers of concrete are tightly combined. After pouring, the concrete surface is plastered to make it smooth.
[0033] First, accurately place the rotating base 101 at the predetermined position of the first-level shaft mouth. Before installation, the surface of the mouth needs to be cleaned to ensure that it is flat and clean. Use measuring instruments to accurately adjust the position and levelness of the rotating base to ensure that its center coincides with the center of the shaft and the levelness error is controlled within the allowable range. Place the rotating top plate 102 on top of the guide rail 106 so that the smooth wear-resistant layer 107 under the rotating top plate 102 fits tightly with the top of the guide rail 106. During the placement process, care must be taken to avoid collision between the rotating top plate and the guide rail to avoid damage to the wear-resistant layer or the guide rail.
[0034] Then install the hook seat 108 on the outside of the rotating top plate 102. During installation, ensure that the hook seat 108 is positioned accurately and firmly connected to the rotating top plate 102. Make the roller 109 on the hook seat 108 fit the bottom of the guide rail 106, and adjust the position of the roller so that it can roll freely on the guide rail. After the installation is completed, perform preliminary debugging on the rotating assembly to check whether the rotating top plate rotates smoothly and whether there is any jamming.
[0035] The lifting rod 305 is lowered to the top of the inner support frame 402 through the lifting motor 309. During the lowering process, the lowering speed and position of the lifting rod must be closely monitored to ensure that the lifting rod reaches the predetermined position accurately. When the lifting rod 305 reaches the top of the inner support frame 402, the connecting sleeve 308 is accurately aligned with the connecting seat 403, and they are firmly connected together using bolts or other connecting parts. When connecting, it is necessary to ensure that the connecting sleeve and the connecting seat fit tightly without gaps.
[0036] During the lowering process of the lifting rod 305, if the length is not enough, it is necessary to add a lifting rod 305 on top. When adding a lifting rod, first align the new lifting rod with the existing lifting rod, make the threaded parts of the two lifting rods accurately butt together, and use a wrench or other tools to tighten the threaded connection to ensure a firm connection. After the addition is completed, check the overall verticality and connection strength of the lifting rod to ensure that it can work normally.
[0037] The driving gear 204 in the driving assembly 2 is meshed with the rack portion 103 on the outside of the rotating top plate 102. During the meshing process, the position of the driving assembly needs to be accurately adjusted to ensure that the meshing clearance between the driving gear and the rack portion meets the requirements. Generally speaking, the meshing clearance should be controlled between 0.2-0.5mm to ensure the accuracy and stability of the transmission. The driving base 201 is fixed to the ground and firmly fixed with anchor bolts or other fixing methods to ensure that the driving assembly does not move during operation.
[0038] After continuing to dig the shaft and building the steel cage 5, the demoulding operation is ready. Before the drive assembly 2 is started, the clamping cylinder 302 is driven first to make the clamping claw 303 clamp the lifting rod 305. The working pressure of the clamping cylinder needs to be reasonably adjusted according to the diameter of the lifting rod and the clamping force requirements to ensure that the clamping claw can firmly clamp the lifting rod, start the drive motor 203, reduce the speed and increase the torque through the reducer 202, and drive the driving gear 204 to rotate. The driving gear 204 is meshed with the rack part 103 for transmission, so that the rotating top plate 102 drives the casting template 4 to rotate to achieve demoulding.
[0039] When the next layer needs to be rotated, the driving motor 203 rotates the casting template 4 in the opposite direction to avoid the rack part 103 from completing its stroke. Each rotation only requires slight demoulding. Generally, the rotation angle is controlled between 5°-10° to prevent excessive bonding between the template and concrete, which may cause difficulty in demoulding or damage to the template.
[0040] After demoulding is completed, the lifting motor 309 of the lifting assembly 3 is started. The lifting motor 309 controls the lifting rod 305 to descend through the cooperation of the clamping wheel 307 and the lifting rod 305, and lowers the casting template 4 to the predetermined position of the next casting section. During the lowering process, it is necessary to pay close attention to the descending speed and position of the lifting rod to ensure that the casting template accurately reaches the predetermined position. At the same time, by adjusting the adjusting bolt 405 in the first sleeve 406, the distance between the arc plate 401 and the well wall is finely adjusted to make the position of the template meet the design requirements.
[0041] Repeat steps S5-S6, and according to the above-mentioned construction method, continuously repeat the operations of digging, building the steel cage, demoulding, lowering the casting formwork, etc., to complete the construction of all casting sections. During each construction process, the construction quality must be strictly inspected to ensure that the construction quality of the steel cage, the pouring quality of the concrete, and the installation quality of the formwork meet the requirements. After the final pouring is completed, the casting formwork 4 is disassembled in blocks. During disassembly, first loosen the bolts connecting the arc plate to separate the arc plate 401 from other components, and then remove the inner support frame 402, the support frame pressure plate 404 and other components in turn. During the disassembly process, pay attention to protecting the formwork and other components to avoid damage.
[0042] After disassembly, it is hoisted out of the well by the lifting assembly 3. The lifting motor 309 is started to raise the lifting rod 305, driving the connecting sleeve 308 and the template components connected thereto to rise. During the lifting process, it is necessary to ensure that the lifting speed is uniform to avoid excessive shaking of the template components. When the template components are lifted to the wellhead position, they are lifted and transported to the designated location for storage using lifting equipment.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
