Description

Technical Field

[0001] This utility model belongs to the field of diaphragm wall construction technology, and in particular relates to a support structure that assists in the construction of diaphragm walls. Background Technology

[0002] Diaphragm wall support is a common deep foundation pit support structure, mainly used in urban underground space development, subway construction, and foundation engineering of high-rise buildings.

[0003] Diaphragm wall support is a vertical continuous wall structure formed by excavating trenches underground and then pouring concrete to support the surrounding soil and prevent soil collapse and groundwater infiltration.

[0004] Concrete is poured during the construction of diaphragm walls. The strength of concrete is gradually formed through the hydration reaction of cement, and the curing time has a significant impact on the strength. It usually takes at least 7 days of curing to reach about 70% of the design strength, and about 28 days to reach the basic design strength. In the current technology, after the diaphragm wall is constructed, the concrete needs to be left to stand. In the current technology, the concrete of the poured diaphragm wall requires a support structure during the curing process. Utility Model Content

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 3As shown, the support structure for the construction of the auxiliary diaphragm wall 14 includes several support devices arranged in sequence; the support devices include splicing bracket assemblies and support frame assemblies; two splicing bracket assemblies are symmetrically arranged on both sides of the diaphragm wall, and several support frame assemblies are arranged between the two splicing bracket assemblies; the splicing bracket assembly includes an upper support plate 1 and a lower support plate 2, and several lower support plates 2 are vertically fixed at the bottom of the upper support plate 1; several mounting blocks 3 are fixed on the lower support plate 2, and support columns 4 are provided on the lower support plate 2 through the mounting blocks 3.

[0034] The device has five lower support plates 2, and each lower support plate has three mounting blocks 3. The number of support columns 4 is the same as the number of mounting plates. The number of support frame assemblies is four.

[0035] A support rod 5 is fixedly installed in the middle of the lower support plate 2. The support rod 5 abuts against the support column, and the support frame assembly abuts against the support column 4. The mounting block 3 is provided with an arc-shaped groove 6 corresponding to the support column 4. The support column 4 is set on the mounting block 3 through the arc-shaped groove 6, and the support column 4 is set parallel to the upper support plate 1.

[0036] One end of the support column 4 is provided with a first positioning block 7, and the other end of the support column 4 is provided with a first groove 8 corresponding to the first positioning block 7. Two support columns 4 can be connected through the first positioning block 7 and the first groove 8, allowing for segmented construction. One end of the upper support plate 1 is provided with a second positioning block 9, and the other end of the upper support plate 1 is provided with a second groove 10 corresponding to the second positioning block 9. The upper support plate 1 is provided with a plurality of evenly distributed mounting holes 11.

[0037] The support frame assembly is positioned between two adjacent mounting blocks 3 and abuts against the support columns 4 on both sides. The support frame assembly includes horizontal bars 12 and vertical bars 13; several horizontal bars 12 are positioned between two vertical bars 13.

[0038] In specific implementation, after the cement of the diaphragm walls 14 on both sides has dried slightly, the upper support plate 1 of the splicing bracket assembly is set on the upper part where the diaphragm wall 14 connects with the ground 15, and the lower support plate 2 is set to abut against the inside of the foundation pit. The splicing bracket assembly is symmetrically arranged. The upper support plate 1 can be fixed by bolts through the mounting holes 11 of the upper support plate 1, so that the upper support plate 1 is connected to the diaphragm wall 14.

[0039] Place the support column 4 on the arc-shaped groove 6 of the mounting block 3, and place it horizontally;

[0040] Support frame assemblies are inserted from top to bottom between multiple mounting blocks 3. The support frame assemblies abut against the support columns, the support columns 4 abut against the support columns, and the support columns are set on the lower support plate 2. The lower support plate 2 provides support for the ground diaphragm wall 14.

[0041] After completing the construction of another section, connect the second groove 10 of the upper support plate 1 to the second positioning block 9. The installation is simple and avoids misalignment. The upper support plate 1 can be fixed with bolts through the mounting holes 11 of the upper support plate 1, connecting the upper support plate 1 to the diaphragm wall 14. Place the support column 4 on the arc groove 6 of the mounting block 3, and connect the first positioning block 7 on one side of the support column 4 to the second groove 10, and place it horizontally. Insert the support frame assembly from top to bottom between multiple mounting blocks 3, and repeat the above operation.

[0042] During disassembly, first pull out the support assembly from bottom to top, then tilt and lift one side of the support column to separate the first positioning block 7 and the first groove 8, thereby completing the disassembly of the support column. Then, remove the bolts of the upper support plate 1 to separate the splicing bracket assembly from the ground diaphragm wall 14, and remove the splicing bracket assembly from the foundation pit.
