Description

Technical Field

[0001] The utility model relates to the technical field of caisson construction, in particular to a large-diameter jacking pipe cast-in-situ working well template casting device. Background Art

[0002] Cast-in-place caisson construction is a common deep foundation construction method, mainly used in engineering projects such as bridges, hydraulic structures, and underground structures that require deeply buried foundations. Caisson construction needs to be adjusted according to changes in the construction environment. For construction sites with hard soil, the process of using pre-loaded caissons becomes very difficult. Due to the geological structure, the caisson is difficult to sink under its own weight. Unlike the conventional caisson pouring sequence, it needs to be poured from top to bottom. As the depth of the working well increases, the angle and depth of the hopper need to be adjusted. The risk of using a crane to lift the hopper is very high, and there are safety hazards in the construction.

DETAILED DESCRIPTION

[0035] like Figure 1-6In the invention, a large-diameter jacking pipe cast-in-situ working pit template casting device includes a hopper 2 arranged at the top of the caisson 1 and a plurality of template units 5 arranged on the inner side of the caisson 1. A moving unit 4 is provided at the bottom of the hopper 2. The moving unit 4 is slidably connected to the top of the caisson 1. The template unit 5 includes a side plate 501. A detachable inclined plate 502 is provided on the upper part of the side plate 501. The adjacent multiple side plates 501 and the geological side wall cooperate to form a casting space for the caisson 1. The hopper 2 completes the filling of the casting space through the discharge pipe 6 and the inclined plate 502.

[0036] During construction, in order to ensure that the forces between different formwork units 5 are balanced, adjacent formwork units 5 are temporarily connected and fixed. The inclined plate 502 is tilted toward the center of the caisson 1, thereby ensuring that there is sufficient opening during pouring, ensuring that the discharge pipe 6 of the hopper 2 can better fill the pouring space. At the same time, the side plate 501 is also tilted toward the center of the caisson 1. Through the above arrangement, the inclined surface 103 of the cast-in-place layer ring 101 can be formed after pouring. The cast-in-place layer ring 101 of the upper layer cooperates with the side plate 501 and the inclined plate 502 to provide sufficient pouring channels for the construction process, ensuring the stability of the construction. Since the geology of the construction area is very hard, the conventional method of applying pre-pressure on the top of the cast-in-place layer ring for sinking is not suitable for the construction of the project. It is necessary to excavate layer by layer from top to bottom and cast in-situ at the excavation site, that is, the position of the cast-in-situ increases with the increase of the caisson depth. The traditional method is to use a crane to lift the hopper 2 and then lower the hopper 2 to the position to be poured. It will not only occupy the space inside the caisson, but also pose a greater safety risk because it is not completely fixed during lifting. This solution completely avoids the above problems. According to the change in the angle of the pouring point, the position of the mobile unit 4 is changed, thereby changing the position of the hopper 2. The discharge pipe 6 on one side of the hopper 2 is very convenient to operate. When in use, it is only necessary to lengthen the discharge pipe 6 according to the depth requirement. The lengthening is carried out by using a clamp for quick installation, which is convenient and stable to use.

[0037] In a preferred solution, the caisson 1 includes a plurality of cast-in-situ layer rings 101 arranged from top to bottom, a crown beam 102 is provided on the top of the uppermost cast-in-situ layer ring 101 , and an inclined surface 103 is provided on the inner side of the crown beam 102 .

[0038] The crown beam 102 provides a good supporting foundation for the mobile unit, while limiting the range of movement, making the installation of the mobile unit 4 more convenient. The number of cast-in-place layer rings 101 increases accordingly with the increase of the depth of the caisson 1. The inclined surface 103 of the upper cast-in-place layer ring 101 cooperates with the formwork unit 5 to provide a sufficiently large casting opening.

[0039] like Figure 13-17 In a preferred embodiment, the mobile unit 4 includes a base 401 , a plurality of first rollers 7 are provided at the bottom of the base 401 , and the first rollers 7 are slidably connected to the crown beam 102 .

[0040] By changing the angle of the first roller 7 , the plurality of first rollers 7 cooperate with each other and make the fixed circle rotation around the axis of the caisson 1 on the crown beam 102 smoother.

[0041] In a preferred embodiment, a first through hole 403 is provided at the top of the base 401, and a mounting bracket 10 is provided on the first roller 7. The mounting bracket 10 is inserted into the first through hole 403 and connected to the base 401 via a nut 9. The position of the first roller 7 can be changed by adjusting the tightness of the mounting bracket 10 and the nut 9.

[0042] In a preferred embodiment, a slide plate 402 is symmetrically slidably connected to the outer side of the base 401 , a second roller 8 is provided on the lower side of the slide plate 402 , and the second roller 8 is slidably connected to the side wall of the crown beam 102 .

[0043] The two side plates of the base 401 are slightly higher than the top of the crown beam 102, and the overall installation is convenient. Then adjust the slide plate 402 to the low point, and the second roller 8 and the inner and outer side walls of the crown beam 102 fit together to protect the base 401. After adjusting to the appropriate position, lock it to ensure that the rolling axis of the second roller 8 is parallel to the axis of the caisson 1, and the movement is smoother.

[0044] In the preferred solution, a fourth through hole 412 and a fifth through hole 413 are provided in parallel on the skateboard 402, the second roller 8 is passed through the fifth through hole 413 through the mounting bracket 10, a bolt 422 is passed through the fourth through hole 412, a slide groove 407 is provided on the side wall of the base 401, the mounting bracket 10 and the bolt 422 are respectively located in the slide groove 407, the synchronization plate 423 is sleeved on the mounting bracket 10 and the bolt 422, and the bolt 422 and the mounting bracket 10 are connected to the synchronization plate 423 through the nut 9.

[0045] The moving range of the bolt 422 on the slide 402 is smaller than the height of the slide groove 407, which ensures the accuracy of the relative movement of the slide 402 and the base 401, and only makes adjustments in the vertical direction. At the same time, the synchronization plate 423 can ensure that the position of the second roller 8 is firmly installed, and the movement process is more stable. The synchronization plate 423 fits into the inner side of the groove 408, which has higher space utilization rate and better effect on the lower part of the base 401.

[0046] In the preferred embodiment, a plurality of first sleeves 404 are evenly distributed on the top of the base 401. Second through-holes 405 are provided through the first sleeves 404 and the base 401. An adjustment rod 414 is rotatably provided in the first sleeve 404. A second threaded hole 411 is provided on the top of the slide 402. The adjustment rod 414 is threadedly connected to the second threaded hole 411. The slide 402 is fitted against the outside of the base 401. Countersunk holes 406 are provided on the lower sides of the second through-holes 405. First threaded holes 409 are symmetrically provided on the sleeves 404. An annular groove 415 is provided on the side of the adjustment rod 414 near the limit plate 416. A locking pin 417 is threadedly connected to the first threaded hole 409, with the end of the locking pin 417 resting against the side wall of the annular groove 415.

[0047] A sixth through hole 418 is provided on the top of the adjusting rod 414, and the insertion rod 420 is inserted into the sixth through hole 418. A holding rod 419 is provided at one end of the insertion rod 420, and a top plate 421 is provided on the top of the holding rod 419. A groove 408 is provided on one side of the slide 407, and the synchronization plate 423 fits in the groove 408. The hopper 2 is connected to the mobile unit 4 through the support platform 3, and a plurality of support legs 301 are provided at the bottom of the support platform 3. A round rod 302 is provided on the lower side of the support leg 301. A plurality of third through holes 410 are provided on the base 401, and the round rod 302 is inserted into the third through hole 410. The round rod 302 is fixed to the base 401 through the nut 9, and the round rod 302 and the nut 9 are threadedly connected.

[0048] The freedom of the adjusting rod 414 is limited by the sleeve 404, while ensuring high precision during rotation. By changing the rotation angle of the adjusting rod 414, the position of the slide 402 can be changed flexibly and conveniently, which is convenient to use. The locking pin 417 and the limit plate 416 cooperate with each other to ensure the stability of the position of the adjusting rod 414 itself, while being able to rotate smoothly and conveniently. It is convenient for the operator to hold the holding rod 419, thereby driving the adjusting rod 414 to rotate, and the insertion rod 420 can act as a lever to improve the efficiency of the adjustment and make it more convenient to use. The support platform 3 and the mobile unit 4 are easy to install and disassemble, and the locking is stable, which ensures that the center of gravity of the hopper 2 is roughly coplanar with the center of gravity of the mobile unit 4, thereby avoiding the stability of unilateral force imbalance and achieving better use effect.

[0049] like Figure 7-12In the preferred embodiment, the lower portion of the side panel 501 is detachably provided with a bottom plate 507, the bottom plate 507 is connected to the ground via a plurality of inserts 506, the bottom plate 507 is connected to the side panel 501 via a support rod 503 and a first push rod 504, the support rod 503 and the first push rod 504 are slidably connected, the outer sides of the support rod 503 and the first push rod 504 are hinged to the bottom plate 507 and the side panel 501 respectively, the support rod 503 and the first push rod 504 are respectively provided with a waist hole 509 and a sixth through hole 508, the support rod 503 and the first push rod 504 are connected via a screw 510 and a nut 9. Two adjacent bottom plates 507 are connected via a locking plate 523, so that the multiple template units 5 have a stable connection as a whole and a strong overall bearing capacity.

[0050] During the process of digging the caisson 1 downward, the bottom of the caisson 1 is leveled during pouring to ensure the convenience of installation of the bottom plate 507. At the same time, a fitting surface is provided on the side of the bottom plate 507 close to the side plate 501. The angle of the fitting surface is consistent with the inclination angle of the side plate 501 when it is designed, thereby ensuring convenience when installing the side plate. The installation position of the side plate 501 is marked with a tool ruler, and then the bottom plate 507 is installed. After the bottom plate 507 is installed, the side plate 501 is placed against the end face of the bottom plate 507. At this time, the support rod 503 and the first top rod 504 are opened, and they are adjusted to the appropriate positions and then fixed. The bottom plate 507 is fastened to the ground by multiple dowels 506. At this time, the screws 510 and nuts 9 are tightened to ensure that it can bear the lateral pressure of the concrete and the overall installation and disassembly are efficient.

[0052] Similarly, when installing the support rod 503 and the first top rod 504 of the first template unit 5, after the fixing is completed, the relative distance between the support rod 503 and the first top rod 504 is obtained. Then, during the installation process of the remaining template units 5, the distance between the support rod 503 and the first top rod 504 is first adjusted to be consistent with the first template unit 5. At this time, it is only necessary to fix the base plate 507 to the ground for quick installation. Different support rods 503 and first top rods 504 have high interchangeability, the overall production is convenient, can be reused, and have strong adaptability.
