Description

Technical Field

[0001] The utility model relates to the technical field of impact countersink construction, in particular to an on-site alignment connection device for a steel casing. Background Art

[0002] When constructing pile foundations in areas with complex geological conditions, the impact countersinking construction process is usually used. This process involves repeatedly hammering the ground with an impact hammer to form a countersink. For construction safety considerations, steel casings must be pre-installed before the countersinking operation. However, the current installation method of steel casings mainly relies on the tamping hammer to alternately hit the edge of the steel casing to force it to penetrate into the mud. This method often results in damaged edges of the steel casing, tilted position of the steel casing, and low installation efficiency, which is disadvantageous in large-scale construction applications. Utility Model Content

[0003] The purpose of the utility model is to ensure the correct position and posture of the steel casing before connection by vertically arranging the positioning rods at the four corners of the fixed base, thereby reducing the docking error and improving the accuracy of construction; the anchor holes on the fixed base allow the use of ground anchors to firmly fix the entire device to the ground, which helps to shorten the construction period, reduce rework caused by manual adjustment or improper alignment, and reduce project costs.

[0005] As a steel casing on-site alignment connection device of the utility model, it is characterized in that the fixed base has evenly distributed anchor holes, which are used to stabilize the base on the ground through ground anchors to ensure the stability of the entire device.

[0006] The utility model provides a steel casing on-site alignment connection device, which has the following beneficial effects:

[0007] The utility model reduces dependence on other heavy equipment, and the modular design of the fixed base and the adjustment mechanism makes storage and transportation more convenient. It also facilitates rapid assembly and disassembly on site, improves operational convenience, saves time and costs, and ensures stability and safety during operation.

[0011] The following will be combined with the drawings in the practical embodiment to clearly and completely describe the technical solution in the practical embodiment. Obviously, the described embodiment is only a part of the embodiment of the practical embodiment, not all of the embodiments. Based on the embodiment in the practical embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical embodiment.

[0012] See also Figure 1 The utility model provides a technical solution: a steel casing on-site alignment connection device:

[0013] In this implementation scheme: first, make a fixed base, select four channel steels of the same length, align their ends and arrange them at right angles to form a square frame structure, use welding technology to firmly weld the adjacent ends of the channel steel, ensure that there are no cracks and pores at the welds, and the welding should be uniform and strong; then make a positioning rod, cut out four pairs of parallel steel plates, the length and width of each pair of steel plates should be consistent to meet the accuracy requirements of positioning, place each pair of steel plates in parallel and keep a certain distance, use welding to weld the corresponding edges of the two steel plates together to form a hollow tubular structure, add reinforcing ribs to the bottom of each welded positioning rod, these reinforcing ribs can be achieved by additional welding of steel plates to increase the contact area and stability of the bottom; make an adjustment bolt, select threaded steel of suitable diameter and length, cut it into a suitable size as the main body of the adjustment bolt, vertically weld a steel plate at one end of the threaded steel as a rotating handle to facilitate manual adjustment, and prepare a matching nut at the other end of the threaded steel for final fixation and adjustment. Place the prepared positioning rods vertically and weld them to the four corners of the fixed base to ensure the verticality and stability of the positioning rods and the base, and drill evenly distributed anchor holes on the fixed base for subsequent ground anchor fixation; carry out site installation, move the entire device to the work site where the steel casing needs to be aligned and connected, use ground anchor screws to pass through the anchor holes on the base to firmly fix the base to the ground to ensure the stability of the device; place the two steel casings that need to be aligned between the positioning rods of the device, use the positioning rods to guide the steel casings to the correct position, and fine-tune the position of the steel casings by adjusting the bolts until the two steel casings are correctly aligned. After confirming that the alignment is accurate, finally tighten the nuts on the adjustment bolts to fix the position of the steel casings.

[0014] Specifically, the fixed base has evenly distributed anchor holes for stabilizing the base on the ground through ground anchors to ensure the stability of the entire device.

[0015] In this embodiment: the positions of the anchor holes are accurately marked on the fixed base to ensure that they are evenly distributed to ensure balanced force after fixation, and the anchor holes are drilled at the marked positions using drilling equipment. The hole size should match the diameter of the ground anchor to ensure that the ground anchor can be smoothly inserted and firmly connected.

[0016] Specifically, a reinforcing rib is provided at the connection between the bottom of the positioning rod and the fixed base to enhance the stability of the connection.

[0017] In this embodiment: a high-strength alloy material is selected to make the reinforcing ribs, and the fixed base and the positioning rod are connected to ensure the stability and durability of the reinforcing ribs and their connecting parts.
