Abstract
Description
Technical Field
[0001] This utility model relates to the field of diaphragm wall construction technology, specifically to a positioning and adjusting frame for implanting in prefabricated diaphragm walls. Background Technology
[0002] Prefabricated diaphragm walls are constructed using specific trenching machinery and methods. Trenching methods primarily involve hydraulic grab buckets for soil removal or mixing machinery for injecting and mixing cement grout to form a water-stopping curtain. Prefabricated diaphragm walls are then inserted at specific intervals (D) to form a continuous prefabricated retaining wall structure. Figure 4 As shown, during construction, the planar positioning and verticality of the precast wall are key control points. If the positioning deviation of the precast wall is too large and it encroaches on the space of the adjacent precast wall, it will affect the installation of the adjacent precast wall and even affect the closure of the overall enclosure wall. Therefore, it is necessary to use a convenient, effective and applicable positioning and adjusting frame to assist in the installation of the precast wall, accurately control the planar positioning and verticality of the precast wall, and ensure smooth construction and project quality.

[0023] The present invention will be further described below with reference to the accompanying drawings.
[0024] like Figure 1 As shown, a positioning and adjusting frame for a prefabricated diaphragm wall includes a frame consisting of an upper steel frame 7, a lower steel frame 3, and four steel frame columns 4; rectangular holes are provided at corresponding positions on the upper steel frame 7 and the lower steel frame 3 for the diaphragm wall to pass through, and the upper steel frame 7, the lower steel frame 3, and the steel frame columns 4 are welded and fixed together.
[0025] A positioning and adjusting frame for implanting prefabricated underground continuous walls also includes a reference positioning device consisting of reference locator A8, reference locator B9, and reference locator C6. The three reference locators are distributed in a triangle, with two reference locators located on the same side of the frame, namely reference locator A installed on the upper steel frame 7 and reference locator B installed on the lower steel frame 3. A reference locator is set on the other side of the frame, namely reference locator C installed on the crossbeam 5 in the middle of the steel frame column.
[0026] A positioning and adjusting frame for prefabricated diaphragm walls is disclosed. The reference locators A8, B9, and C6 are identically configured. The frame includes a housing 10, guide rollers 11, roller brackets 12, and roller adjusting cylinders 13. The roller brackets are slidably fitted inside the housing 10. The guide rollers 11 are mounted on the roller brackets 12. The roller adjusting cylinders 13 are fixedly mounted inside the housing, and the telescopic rod of the roller adjusting cylinders 13 is fixedly connected to the roller brackets 12. The prefabricated wall is positioned in planar orientation by adjusting the rollers.
[0027] The reference positioning device uses two reference positioners located on one side of the frame to provide the vertical normal line for the precast wall through guide rollers, while the reference positioner on the steel frame column on the other side provides the reaction force for the precast wall, restricting the lateral movement of the precast wall and ensuring that it is always placed along its vertical normal line.
[0028] A positioning and adjusting frame for implanting prefabricated underground continuous wall also includes four bases set at the bottom of the lower steel frame 3 of the frame body, and base adjusting cylinders 1 are respectively set on the bases. The levelness of the frame body can be controlled by the base adjusting cylinders 1.
[0029] A positioning and adjusting frame for embedded prefabricated diaphragm walls also includes a control box 2. The control box contains a display, a high-resolution tilt sensor, a computer board, and operating switches, enabling one-button leveling of the frame. The base adjusting cylinder 1 and the roller adjusting cylinder 13 are controlled via the control box.
[0030] How to use:
[0031] 1) Place the positioning and adjusting frame at the predetermined position of the opening under the precast wall;
[0032] 2) Start the one-button leveling switch on the control box, adjust the base adjusting cylinder, and adjust the frame of the positioning and vertical adjustment frame to a horizontal state;
[0033] 3) Adjust the two upper and lower reference locators on one side (these two locators are adjusted synchronously with one key) to adjust the contact surface of the guide roller to the design plane position of the precast wall, which serves as the reference line for the plane positioning and vertical lowering of the precast wall;
[0034] 4) Hoist the precast wall into the frame of the positioning and adjusting frame, and place the precast wall close to the guide roller. Then activate one of the reference locators on the other side to restrict the lateral movement of the precast wall, so that it is always lowered according to the plane positioning point and vertical normal provided by the reference locator on the opposite side, thus ensuring the plane positioning and verticality of the precast wall when it is lowered.
