Description

A verticality control device and its application method for large-diameter steel pipe columns constructed in reverse. Technical Field

[0001] This invention relates to the field of steel pipe column construction technology, specifically to a verticality control device and its usage method for large-diameter steel pipe columns constructed in reverse. Background Technology

[0002] Currently, steel pipe columns are commonly used as the main load-bearing structure of underground railway stations, and their installation accuracy has a significant impact on the quality and safety of subsequent construction. To alleviate passenger flow, current underground railway station designs are gradually expanding deeper underground, resulting in increasingly larger and longer steel pipe column structures.

[0003] With the development of steel pipe column construction technology in recent years, there are now two methods for ensuring the verticality of steel pipe columns using reverse construction: Method 1: Construction personnel need to enter the interior of the steel pipe column and adjust the lower end of the column to meet the verticality requirements; Method 2: The device for adjusting the lower end of the steel pipe column is connected to the lower end of the column by welding or binding, and construction personnel manually adjust the verticality of the lower end of the steel pipe column from outside the pile hole or steel casing using the device.

[0004] However, both of these methods have certain drawbacks:

[0005] The verticality of the lower end of the steel pipe column needs to be manually adjusted, resulting in low construction efficiency and complexity. This greatly increases the construction intensity of the workers, is not economical, and cannot guarantee the construction period. It also poses safety hazards and has poor stability. When the verticality of the steel pipe column is adjusted and the device needs to be retrieved, it is easy to interfere with the steel pipe column, causing the verticality of the steel pipe column to drop and the device to fall. It is also impossible to quickly adjust the verticality of the steel pipe column and the verticality adjustment accuracy is not high. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a verticality control device and method for the reverse construction method of large-diameter steel pipe columns.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A verticality control device for a large-diameter steel pipe column in reverse construction includes a ground surface, a pile hole drilled in the ground surface, a steel casing disposed on the ground surface and located within the pile hole, a steel pipe column disposed inside the steel casing, a connecting ring seat disposed on the ground surface and located outside the pile hole, an operating seat disposed on the connecting ring seat for connecting to the upper end of the steel pipe column and leveling the upper end of the steel pipe column, and several units connected between the connecting ring seat and the operating seat for adjusting the verticality of the operating seat and the steel pipe column. The system includes: a leveling component connected to the upper drive operating seat for leveling the upper end of the steel pipe column; a base plate located outside the lower end of the steel pipe column and parallel to the operating seat; several fixed ends abutting against the column body of the steel pipe column and horizontally arranged on the base plate for adjusting the telescopic ends abutting against the inner wall of the steel casing after the leveling components drive the operating seat to level the upper end of the steel pipe column; and an adjustment component located on the operating seat for monitoring the verticality error data of the steel pipe column after the telescopic ends of the adjustment components abut against the inner wall of the steel casing. A verticality measuring device that transmits verticality error data of the steel pipe column; a data receiving and control device located on the ground and on one side of the connecting ring seat, for receiving the verticality error data of the steel pipe column monitored by the verticality measuring device and controlling the extension and retraction of the corresponding adjusting parts according to the verticality error data of the steel pipe column so that the verticality of the steel pipe column meets the predetermined requirements; an electromagnetic adsorption device located on the adjusting parts, for horizontally adsorbing the adjusting parts onto the base plate before the verticality of the steel pipe column meets the predetermined requirements to prevent the adjusting parts from detaching from the base plate, and for no longer adsorbing the adjusting parts onto the base plate after the verticality of the steel pipe column meets the predetermined requirements and after the steel pipe column has completed concrete pouring and backfilling of sand and gravel to the base plate position; and a recovery device located on the operating seat, for pulling out several adjusting parts from the steel casing for recovery when the electromagnetic adsorption device no longer adsorbs the adjusting parts onto the base plate; the data receiving and control device is communicatively connected to the verticality measuring device; and the data receiving and control device is electrically connected to several of the adjusting parts.

[0009] A further improvement is that: several of the leveling components are electrically connected to the data receiving and control device so that the data receiving and control device automatically controls the several leveling components to drive the operating seat to level the upper end of the steel pipe column; and / or, the data receiving and control device is electrically connected to the recycling device so that when the electromagnetic adsorption device no longer adsorbs the adjustment components onto the base plate, it automatically controls the recycling device to pull the several adjustment components out of the steel casing for recycling.

[0010] A further improvement is that the steel pipe column is provided with an arc-shaped seat on its body for the fixed end of the adjusting member to abut against, thereby improving the stability of the adjusting member during adjustment. The telescopic end of the adjusting member is an arc-shaped end for fitting the steel casing, thereby improving the stability of the adjusting member during adjustment.

[0011] A further improvement is that the base plate is provided with at least two limiting seats to limit the adjustment component before the electromagnetic adsorption device stops adsorbing the adjustment component onto the base plate, thereby enhancing the stability of the adjustment component.

[0012] A further improvement is that the recycling device includes a winch disposed on the connecting ring seat and located above the adjusting member, and a recycling line with one end disposed on the winch and the other end connected to the adjusting member.

[0013] A further improvement is that the leveling component is a leveling hydraulic cylinder, and the adjusting component is a hydraulic cylinder.

[0014] A further improvement is that the recycling line includes a hydraulic pipeline, several steel strands disposed outside the hydraulic pipeline, a second data line disposed outside the hydraulic pipeline and located between adjacent steel strands, and a galvanized steel strip spirally wound around the several steel strands and the several second data lines.

[0015] Based on the same inventive concept, this invention also provides a method for using a verticality control device for a large-diameter steel pipe column in a reverse construction method: A pile hole is drilled in the ground; a steel casing is installed in the pile hole; the steel pipe column is placed inside the steel casing; a connecting ring seat is placed in the ground outside the pile hole; an operating seat is connected to the upper end of the steel pipe column; several leveling components drive the operating seat to level the upper end of the steel pipe column after the operating seat is connected to the upper end of the steel pipe column; several adjusting components, after driving the operating seat to level the upper end of the steel pipe column, have their telescopic ends abut against the inner wall of the steel casing; and a verticality measuring device monitors the verticality error data of the steel pipe column after the telescopic ends of the adjusting components abut against the inner wall of the steel casing and transmits the data. The verticality error data of the steel pipe column is transmitted. The data receiving and control device receives the verticality error data of the steel pipe column monitored by the verticality measuring device and controls the extension and retraction of the corresponding adjusting parts according to the verticality error data of the steel pipe column to ensure that the verticality of the steel pipe column meets the predetermined requirements. Before the verticality of the steel pipe column meets the predetermined requirements, the electromagnetic adsorption device horizontally adsorbs the adjusting parts onto the base plate to prevent the adjusting parts from detaching from the base plate. After the verticality of the steel pipe column meets the predetermined requirements and the concrete pouring and backfilling of sand and gravel to the base plate position are completed, the adjusting parts are no longer adsorbed onto the base plate. When the electromagnetic adsorption device no longer adsorbs the adjusting parts onto the base plate, the recovery device pulls out several adjusting parts from the steel casing for recovery.

[0016] After adopting the above technical solution, the beneficial effects of the present invention are as follows: there is no need to manually adjust the verticality of the lower end of the steel pipe column, which greatly improves the construction efficiency and is simple and convenient, greatly reduces the construction intensity of construction personnel, improves the economy and ensures the construction period, reduces safety hazards and improves stability. When the verticality of the steel pipe column is adjusted and the device needs to be retrieved, it is not easy to interfere with the steel pipe column and cause the verticality of the steel pipe column to drop, and it is not easy to cause the device to fall. The verticality of the steel pipe column can be adjusted quickly and the verticality accuracy of the adjustment is improved.

[0017] Further benefits: The installation of several steel strands and galvanized steel strips prevents the adjustment components from accidentally falling off due to breakage of the recovery line during recycling. Attached Figure Description
