Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a movable temporary support device for guiding walls. Background Art

[0002] The underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous reinforced concrete wall underground as a water interception, anti-seepage, load-bearing and water retaining structure.

[0003] The guide wall of the ground-anchored wall is the first step in the construction of the ground-anchored wall. Its main functions are to retain soil, store mud and guide the construction of the ground-anchored wall, which directly affects the subsequent construction quality of the ground-anchored wall. After the construction of the guide wall of the ground-anchored wall is completed, effective support must be taken to prevent the guide wall from being squeezed and deformed; however, these support structures will cause the trenching machine to be unable to grasp the trench during the subsequent trenching construction. Therefore, during the trenching construction process, the support structure located in the trenching section and the support structure adjacent to the trenching section for laying mud circulation equipment also need to be removed. Due to the large removal area, in order to avoid the risk of extrusion and deformation of the guide wall during the trenching construction, a temporary support structure needs to be set between the guide walls adjacent to the trenching section to ensure the trenching construction effect.

[0004] At present, the common construction practice is to process small-sized steel according to the size of the guide wall for support. However, one disadvantage of using small-sized steel as a support structure is that the small-sized steel has poor bending resistance and there is a risk of bending due to extrusion of the guide wall, resulting in support failure. Another disadvantage is that the small-sized steel support structure needs to be customized, which makes it impossible to recycle, resulting in excessively high construction costs and a large waste of resources.

[0005] In order to solve the above technical problems, the published patent CN202011587666.3 proposes an adjustable formwork device for supporting a guide wall and a guide wall supporting method, including a first supporting formwork, a second supporting formwork sleeved on one end of the first supporting formwork and a locking mechanism, the second supporting formwork is configured to be able to reciprocate along the length direction of the first supporting formwork, and the end of the first supporting formwork away from the second supporting formwork and the end of the second supporting formwork away from the first supporting formwork are respectively hinged with L-shaped guide wall hanging plates, the locking mechanism is used to lock or unlock the first supporting formwork and the second supporting formwork, and a grouting port is provided on the top of the first supporting formwork and / or the second supporting formwork. The advantage is that it can adapt and support guide walls with different spacings, thereby improving the utilization rate of the device, but the disadvantage is that the process is complicated and the structural stability is poor. The published patent CN201922135367.5 proposes a guide wall support device for underground continuous wall engineering, which includes a middle support assembly, and end support assemblies are arranged on both sides of the middle support assembly, and the end support assemblies are clamped in the clamping grooves on both sides of the middle support assembly, and the middle support assembly can move in the vertical direction to adjust its position relative to the end support assemblies. The utility model provides a guide wall support device for underground continuous wall engineering, which has a reasonable structure and convenient construction, and realizes reliable support of the guide wall for underground continuous wall engineering. Its advantages are convenient construction and the device can be recycled, but its disadvantages are insufficient support structure strength and the risk of bending after extrusion.

[0013] Furthermore, the length of the concrete block is greater than the spacing between adjacent temporary support frames of the guide walls.

[0026] The temporary support frame 3-2 for the guide wall includes a U-shaped frame body formed by a first vertical plate, a horizontal plate and a second vertical plate which are vertically arranged and connected in sequence, and a sleeve is horizontally fixed on the top surface of the first vertical plate and the second vertical plate respectively along the length direction of the vertical plate; wherein the axial length of the sleeve is the same as the top surface length of the vertical plate, and the inner diameter of the sleeve is slightly larger than the outer diameter of the temporary support rod 3-1 for the guide wall, so that the temporary support frame 3-2 for the guide wall can be movably sleeved on the two temporary support rods 3-1 for the guide wall through the two sleeves thereon, and the position of the temporary support frame 3-2 for the guide wall on the temporary support rod 3-1 can be adjusted according to actual needs; in this embodiment, the U-shaped frame body is formed by cutting and welding, and the sleeve is formed by cutting a steel round tube into a suitable length, and the sleeve is welded and fixed on the top side of the U-shaped frame body; the number of temporary support frames 3-2 for the guide wall is adapted to the size of a single temporary support frame 3-2 for the guide wall and the width of the guide groove between the guide walls 1 on both sides, so that when multiple temporary support frames 3-2 for the guide wall are arranged in a straight line with equal intervals, their total length is less than the width of the guide groove.

[0027] The concrete block 3-3 is a cubic block formed by pouring and curing concrete, and its size is adapted to the temporary support frame 3-2 for the guide wall, so that multiple concrete blocks 3-3 are arranged in a line and set in the temporary support frame 3-2 for the guide wall; wherein, the length of the concrete block 3-3 is greater than the spacing between adjacent temporary support frames 3-2 for the guide wall, so as to avoid the concrete block from being unstable and falling to the bottom of the guide groove due to excessive spacing; the number of concrete blocks 3-3 is adapted to the size of a single concrete block 3-3 and the width of the guide groove between the guide walls 1 on both sides, so that when multiple concrete blocks 3-3 are arranged in a line and built into multiple temporary support frames 3-2 for the guide wall, the concrete blocks 3-3 located at both ends partially extend to the outside of the temporary support frames 3-2 for the guide wall located at both ends; as a preferred technical solution of this embodiment, two handles 3-4 are symmetrically arranged on the top surface of each concrete block 3-3, so as to transport or lift the concrete block 3-3 into the U-shaped frame built into the temporary support frame 3-2 for the guide wall by the handles 3-4.
