Abstract

The utility model relates to a diaphragm wall guide wall, and belongs to the technical field of building or reinforcing of the edge of a foundation pit. The diaphragm wall guide wall comprises two rows of parallel and vertical wallboards. The wallboard is formed by transversely splicing a plurality of guide plates, every two adjacent guide plates at the position needing to be turned are connected through a hinge, and every two adjacent guide plates are connected through a mortise and tenon joint under other conditions. A bendable thin plate covers the hinge position of every two adjacent guide plates; a plurality of symmetrical supporting plates are arranged on the opposite sides of the two rows of wallboards, the supporting plates are fixed to the wallboards through L-shaped baffles, a plurality of first threaded sleeves are fixed to the supporting plates, threaded rods are in threaded connection with the interiors of the first threaded sleeves, and every two opposite threaded rods are in threaded connection through a second threaded sleeve. The distance between the two opposite threaded rods can be adjusted through rotation of the second threaded sleeve. When the distance between the ground diaphragm wall groove sections changes, the two guide plates connected through the hinge form a bend so as to be attached to the ground diaphragm wall.

Description

Technical Field

[0001] The utility model relates to a ground-connected wall guide wall, belonging to the technical field of repairing or reinforcing the edge of a foundation pit (E02D17 / 04). Background Art

[0002] With the acceleration of urbanization, the demand for the utilization of underground space is increasing. Guide walls are an important component of ground-connected wall construction. They provide accurate benchmarks and directions for subsequent ground-connected wall construction, ensuring the verticality and position accuracy of the entire wall. Traditional ground-connected wall guide walls require a large number of nails to be driven into the joints of the wall panels to ensure the firmness of the guide walls. When faced with ground-connected walls with varying spacing between slot sections, it is also necessary to re-cut short wooden piles of appropriate lengths, or to insert wood into the gaps between the wall and the wall panels for support. This process not only consumes a lot of time and human resources, but also increases the complexity of construction. In the patent document with publication number CN219157709U, a prestressed composite steel inner support for foundation pits in soft soil areas is proposed. The sleeves on both sides are connected by threaded rods, which can be adjusted and telescopically squeezed on the inner side of the foundation pit steel plate, and the bottom is supported on the ground and the inner side of the bottom of the foundation pit steel plate by an adjustable support tube, thereby improving the supporting force. While this patent improves support to a certain extent, when the ground-connected wall bends and the spacing between the slots changes, the wall panels cannot adapt to the ground-connected walls on both sides, and the verticality of the ground-connected walls cannot be guaranteed. As the bending angle of the ground-connected wall increases, the shortcomings of this patent become more obvious.

[0003] Therefore, there is an urgent need for a ground-connected wall guide wall that can adapt to changes in the spacing between ground-connected wall groove sections. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to improve the adaptability of the guide wall of the ground-connected wall to the change of the distance between the ground-connected walls.

[0005] The technical solution proposed by the present invention to solve the above-mentioned technical problems is: a ground-connected wall guide wall, comprising two rows of parallel upright wall panels; the wall panels are formed by horizontally splicing a plurality of guide panels, and the two adjacent guide panels are connected by hinges at a turning point, and the two adjacent guide panels are connected by mortise and tenon joints in other cases; the hinges of the two adjacent guide panels are covered with bendable thin plates; a plurality of symmetrical support plates are provided on the opposite side of the two rows of wall panels, and the support plates are fixed to the wall panels through L-shaped baffles, and the support plates are fixed with a plurality of first threaded sleeves, and the first threaded sleeves are all screwed with threaded rods, and the two opposite threaded rods are screwed with each other through second threaded sleeves, and the spacing between the two opposite threaded rods is adjustable by rotating the second threaded sleeves; when the spacing between the ground-connected wall groove sections changes, the two guide panels connected by hinges are bent to fit the ground-connected wall.

[0006] Furthermore, the support plates are evenly distributed along the wall panels, and the support plates with larger sizes are distributed at the mortise and tenon joints of the guide plates.

[0007] Furthermore, one of the two adjacent guide plates connected by the hinge is fixed with a pin groove, and the other guide plate is fixed with a pin piece.

[0008] The beneficial effects of this utility model are as follows: because two rows of wall panels are provided with multiple symmetrical support plates on opposite sides, the support plates are secured to the wall panels via L-shaped baffles. The support plates are secured with multiple first threaded sleeves, each of which has a threaded rod threaded into it. The opposing threaded rods are threaded together via second threaded sleeves, and the spacing between the opposing threaded rods is adjustable by rotating the second threaded sleeves. Therefore, the spacing between the two rows of wall panels can be adaptively adjusted based on the spacing between the floor tie wall slot sections. Furthermore, because two adjacent guide plates are hingedly connected, if a section of the floor tie wall bends, the guide plates can bend to accommodate the bending of the floor tie wall and reattach to the wall. The guide wall is screwed and spliced together, making it easy to disassemble and adjust adaptively. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Example

[0016] A ground-connected wall guide wall of this embodiment is as follows Figure 1 As shown, it comprises two rows of parallel vertical wall panels 1; the wall panels 1 are formed by horizontally splicing a plurality of guide plates 2. Two adjacent guide plates 2 are connected by hinges 11 at the turning point, and are connected by mortise and tenon joints in other cases; the hinges of the two adjacent guide plates 2 are covered with bendable thin plates 3; Figure 2 、3 As shown, a plurality of symmetrical support plates 4 are provided on opposite sides of the two rows of wall panels 1. The support plates 4 are evenly distributed along the wall panels 1. The larger support plates 4 are distributed at the mortise and tenon joints of the guide plates 2. The support plates 4 are fixed to the wall panels 1 through L-shaped baffles 5, which provide strong support and prevent leakage at the same time; the support plates 4 are fixed with a plurality of first threaded sleeves 6, and the first threaded sleeves 6 are screwed with threaded rods 7. The two opposite threaded rods 7 are screwed to each other through second threaded sleeves 8. The spacing between the two opposite threaded rods 7 is adjustable by rotating the second threaded sleeves 8. Therefore, the spacing between the two rows of wall panels 1 can be adaptively adjusted according to the spacing between the ground connection wall groove sections. The guide wall is suitable for ground connection walls with different groove spacings; when the same section of the ground connection wall is bent, resulting in a change in the groove section spacing, the two guide plates 2 connected by the hinges 11 are bent to adapt and fit the ground connection wall again.

[0017] like Figure 4 As shown, of the two adjacent guide plates connected by the hinge 11 , one of the guide plates 2 is fixed with a pin groove 9 , and the other guide plate is fixed with a pin piece 10 , which is inserted into the pin groove 9 to form the hinge 11 .

[0018] The present invention is not limited to the above embodiments, and any technical solutions formed by equivalent replacements fall within the protection scope required by the present invention.
