Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe column positioning, and particularly to a steel pipe column verticality adjusting machine for top-down construction method. BACKGROUND

[0002] The top-down construction method is a kind of underground engineering construction technology, which forms a temporary road surface support by first constructing side walls, columns and roof, then restores the ground traffic, and then excavates and constructs the main structure from top to bottom. The core is to use the roof and the column to bear the load cooperatively, and the side wall has the functions of transmitting vertical force and resisting lateral earth pressure, which is suitable for urban shallow underground engineering and scenarios that need to reduce road occupation. The steel pipe column is a commonly used building support structure, which is mainly used to bear the horizontal load, vertical load and seismic load of the building. The steel pipe column has the advantages of simple structure, easy construction, strong bearing capacity and good seismic resistance. In the top-down construction method, the steel pipe column is widely used in the structure of supporting buildings and plays a key role.

[0003] In the construction process of the steel pipe column, a verticality adjusting machine is needed. The existing verticality adjusting machine judges whether the center of the verticality adjusting machine base is aligned with the center of the hole and whether the steel pipe column remains vertical during the insertion process by using total station and inclinometer measuring instruments. This measurement method has a lag and cannot provide real-time feedback of measurement data, and the human error is large and the measurement efficiency is low.

[0004] Secondly, the existing verticality adjusting machine adjusts the whole machine body through the supporting legs to adapt to the situation, so as to ensure that the steel pipe column remains vertical. However, the movement of the machine body will drive the suspension device and the clamping device on the machine body, which will affect the leveling. In order to ensure that the steel pipe column remains vertical as much as possible, the supporting legs need to be adjusted adaptively many times, which reduces the construction efficiency.

[0005] During the operation of the verticality adjusting machine, the machine body will often tilt due to ground subsidence and other external forces. This tilt is often difficult to be found by conventional measuring instruments. The tilt of the machine body will drive the clamping device on the machine body, which will eventually cause the steel pipe column to not be inserted from the center of the hole. SUMMARY

[0055] A plurality of fuselage inclination observation assemblies 600 are arranged circumferentially on the positioning sleeve 110, and the plurality of fuselage inclination observation assemblies 600 are matched to clamp the second clamping device 300.

[0056] In some embodiments, before the steel pipe column 500 is inserted, a rotary excavator is used to form a hole in the ground. After the hole is formed, the positioning sleeve 110 is inserted into the hole to prevent the soil within a certain depth below the ground from collapsing.

[0058] The first clamping device 400 and the second clamping device 300 are arranged on the leveling machine base 100, the first clamping device 400 can clamp the steel pipe column 500, the first lifting assembly 900 lowers the first clamping device 400, thereby realizing the insertion of the steel pipe column 500, when the first lifting assembly 900 lowers the first clamping device 400 to a certain height, the second clamping assembly clamps the steel pipe column 500, the first clamping assembly releases the steel pipe column 500, and the first lifting assembly 900 raises the first clamping device 400. After several reciprocations, the steel pipe column 500 is pressed into the design elevation.

[0059] Reference Figures 3-6 In an optional embodiment, the fuselage inclination observation assembly 600 comprises a support arm 601 and a measuring arm 604, one end of the support arm 601 is connected with the positioning sleeve 110, and the other end extends radially along the positioning sleeve 110;

[0062] One end of the support arm 601 of the body tilting observation assembly 600 is connected with the positioning sleeve 110, and the other end is connected with the measuring arm 604. The support arm 601 has a certain distance between the measuring arm 604 and the positioning sleeve 110, so that the measuring arm 604 is located outside the main body of the leveling machine.

[0063] The support arm 601 has a sliding groove 606. One end of the guide rod 605 is screwed in the sliding groove 606. The measuring arm 604 is sleeved on the guide rod 605. The guide rod 605 is sleeved with a tension spring 607. The tension spring 607 is in a tension state, so that the measuring arm 604 always keeps in abutment with the second clamping device 300.

[0064] In the optional embodiment, two sides of the lower end of the support arm 601 are respectively provided with a roller 608. Two sides of the sliding groove 606 along the length direction of the guide rod 605 are respectively formed with a guide groove 602. The roller 608 is assembled in the guide groove 602.

The first scale mark 603 is arranged on the support arm 601. When the main body of the leveling machine is inclined, the main body of the leveling machine moves the measuring arm 604 along the sliding groove 606. That is, the scale of the corresponding first scale mark 603 on the support arm 601 changes. Then, whether the main body of the leveling machine is inclined and the degree of inclination are determined.
