[0002] In the support engineering of deep foundation pits, if the support method of concrete internal support + steel lattice column is used to support the foundation pit, the installation elevation and plane angle of the lattice column are particularly important. If the elevation of the lattice column is not properly controlled during construction, the concrete internal support cannot be effectively stressed, and there are major safety hazards such as instability of the foundation pit support. And when the lattice column is connected to the internal support, the installation angle of the lattice column is also very important. If it cannot be kept the same as the design angle in the design drawing, the reinforcement of the steel bars at the connection node will not be able to be constructed normally. Therefore, during the construction of the lattice column, the process of its elevation and fixing angle is the key control and focus of the construction.

[0003] When the top elevation of the installed lattice column is below the ground, its elevation and angle will be difficult to control. It can only be hoisted and installed after the excavation reaches a fixed elevation. It is impossible to carry out cross-construction in advance, which seriously affects the construction period and has a significant impact on the progress of the project. Summary of the invention

[0036] As a preferred embodiment, the base 1 includes: a surface frame 11 , an inner casing 12 , spokes 13 , and an outer casing 14 .

[0037] The face frame 11 is square and is laid on the ground. The frame opening of the face frame 11 is aligned with the pile hole.

[0038] The inner casing 12 is arranged in the frame opening of the face frame 11. The inner diameter of the inner casing 12 is adapted to the inner diameter of the pile hole. The inner casing 12 is arranged coaxially with the pile hole.

[0039] There are multiple spokes 13. The spokes 13 are connected to the inner casing 12 and the face frame 11. The multiple spokes 13 are arranged along the circumferential direction of the inner casing 12.

[0040] The outer casing 14 is mounted on the plurality of spokes 13. The outer casing 14 is sleeved on the outside of the inner casing 12. The outer casing 14 is coaxially arranged with the inner casing 12. An annular groove 10 is formed between the outer casing 14 and the inner casing 12.

[0041] The rotary ring 2 is rotatably embedded in the annular groove 10 .

[0042] In this embodiment, the height of the rotating ring 2 is greater than the depth of the annular groove 10 .

[0043] As a preferred embodiment, the thickness of the rotating ring 2 is adapted to the groove width of the annular groove 10 .

[0044] The support frame 3 is installed at the upper ring opening of the revolving ring 2. The support frame 3 is installed with a plurality of hanging plates 32. The lower end of the hanging plate 32 is connected with a hook 321. The gusset plate 41 of the underground lattice column 4 is hung on the hook 321. The underground lattice column 4 is coaxially arranged with the revolving ring 2.

[0045] Specifically, the support frame is in a tic-tac-toe shape. The support frame 3 includes four beams 31. The four beams 31 are connected end to end. Each beam 31 is equipped with a hanging plate 32.

[0046] The present invention provides a construction method of an underground lattice column hoisting and positioning device, comprising the following steps:

[0047] S1. Drilling pile holes on the ground to form underground lattice columns 4.

[0048] S2. Lay the base 1 on the ground so that the through hole 100 of the base 1 is coaxially arranged with the pile hole and the bottom is arranged in the horizontal direction.

[0049] S3, hoisting the underground lattice column 4 and lowering it into the pile hole through the through hole 100.

[0050] S4. Hang the supporting plate 41 of the underground lattice column 4 on the hook 321 at the lower end of the hanging plate 32.

[0051] S5. The rotary ring 2 is rotatably embedded in the annular groove 10 of the base 1, so that the top elevation of the underground lattice column 4 is at the designed elevation.

[0052] S6. By rotating the revolving ring 2, the azimuth angle of the underground lattice column 4 is made to conform to the designed azimuth angle.

[0053] In this embodiment, the base is welded by a square face frame and inner and outer casings. The outer casing has the same diameter as the pile hole, and the diameter of the inner casing is the same as the circumscribed circle of the underground lattice column. An annular groove is formed between the inner and outer casings for clamping with the rotating ring above to ensure that the underground lattice column is always at the center point of the intended installation aperture when the angle is adjusted.

[0054] Six bolt holes are reserved on the inner side of the support frame for fixing the hanging plate. The square formed by the support frame is the same size as the underground lattice column. The upper end of the hanging plate is connected and fixed to the beam of the support frame with screws, and the lower end of the hanging plate is bent to form a hook that can be stuck on the gusset plate of the underground lattice column to ensure that when the rotating ring is rotated, the underground lattice column can be rotated at the same time.

[0055] After the drilling rig has completed drilling, install the base on the top of the hole, and then install the rotating ring. After the two are installed, the underground lattice column is hoisted. After the underground lattice column is hoisted down to the specified elevation, install the hanging plate. The lower end of the hanging plate is clamped with the gusset plate, and the upper end of the hanging plate is connected to the rotating ring with bolts. After completing the above operations, the lattice column can be hoisted down until the rotating ring contacts the ring groove, indicating that the underground lattice column has been hoisted to the required elevation underground. After that, start rotating the rotating ring to adjust the lattice column azimuth angle. After the angle adjustment is completed, the lattice column can be fixed and cast.

[0056] After pouring is completed and the lifting rope is removed, the fixing screws above the hanging plate can be loosened, the hanging plate and the device can be removed, and the construction of the next lattice column can be started.

[0057] The underground lattice column hoisting and positioning device of the present invention can effectively control the elevation and adjust the angle of the lattice column whose top elevation is below the ground during installation. It is efficient and convenient to operate and can be repeatedly used. It has good on-site use effect and extremely high economic benefits. The underground lattice column hoisting and positioning device of the present invention reduces the project construction cost, speeds up the project construction progress, achieves good economic benefits for the project, and has good prospects for promotion and application.
