Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a chiseling-free ground-connected wall structure. Background Art

[0002] With the rapid growth of urban rail transit construction in China, subway station diaphragm walls, also known as underground continuous walls, are a crucial retaining structure in subway station construction, serving multiple functions, including support, water interception, and anti-seepage. Their construction process includes trenching, cage installation, and concrete pouring. They possess significant rigidity and integrity, effectively improving the stability and load-bearing capacity of the project structure. Subway station diaphragm walls play a crucial role in subway construction, not only providing support during the construction phase but also serving as a permanent part of the station structure after completion, ensuring its stability and safety.

[0003] Diaphragm wall foundation pits are a common structural form in building construction, used to support and protect the surrounding soil and groundwater. Traditional diaphragm wall pit construction methods are subject to high costs and long construction periods. In traditional diaphragm wall pit projects, the pit support structure is typically made of reinforced concrete. While these materials provide some support, their subsequent removal results in wasted concrete and does not meet the requirements of green construction. Furthermore, the weight and construction difficulty of traditional materials limit their application in complex environments.

[0004] For example, patent CN110295589A discloses a ground-connected wall anchor bar protection structure, which includes: a ground-connected wall, a steel cage inside the ground-connected wall, and anchor bar rows arranged in a line formed by a number of anchor bars on opposite sides of the upper part of the ground-connected wall. The anchor bar rows form an outer wall to accommodate over-poured concrete of the ground-connected wall. The anchor bar rows are provided with anchor bar protection devices, including outer plates, inner plates and anchor nails connecting the outer plates and inner plates respectively arranged on both sides of the anchor bar rows. Although no chiseling is required, the construction is cumbersome. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a ground-connected wall structure that does not require chiseling, so as to achieve the purpose of supporting without chiseling and shortening the construction period.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The ground-connected wall structure that does not require removal includes a concrete rigid connection construction waterproof structure and an inner side protective structure of the ground-connected wall foundation pit. A steel frame structure is provided inside the concrete rigid connection construction waterproof structure and the inner side protective structure of the ground-connected wall foundation pit, and a hoisting structure is provided corresponding to the steel frame structure. A corrugated plate is provided on one side of the inner side protective structure of the ground-connected wall foundation pit.

[0008] Further:

[0009] The concrete rigid connection construction waterproof structure includes vertical bars welded by lifting rings, vertical bars of steel cage, horizontal truss bars and shear bars. The horizontal truss bars and shear bars are all connected to the vertical bars of steel cage and vertical bars welded by lifting rings.

[0010] The corrugated plate is a vertically arranged plate structure.

[0011] The inner side protective structure of the ground-connected wall foundation pit includes connected horizontal truss bars and truss diagonal bars.

[0012] Corresponding to the horizontal truss reinforcement, a continuous wall distribution reinforcement densification reinforcement structure is provided, and the continuous wall distribution reinforcement densification reinforcement structure includes upper continuous wall distribution reinforcement densification reinforcement located at the upper part and lower continuous wall distribution reinforcement densification reinforcement located at the lower part.

[0013] A rear vertical steel bar scaffold is provided at the bottom of the concrete rigid connection construction waterproof structure.

[0014] Positioning pads are provided at the ends of the truss diagonal reinforcements.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The ground-connected wall structure that does not require chiseling is reasonably designed. By setting up a hoisting steel structure and corrugated plates on the side, no subsequent chiseling is required, which optimizes the verticality of the ground-connected wall construction throughout the entire process, shortens the construction period, and ensures the stability and durability of the ground-connected wall.

[0022] The specific implementation of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the ground-connected wall structure that does not require chiseling includes a concrete rigid connection construction waterproof structure and an inner side protective structure of the ground-connected wall foundation pit arranged side by side. A steel frame structure is provided inside the concrete rigid connection construction waterproof structure and the inner side protective structure of the ground-connected wall foundation pit, and a hoisting structure is provided corresponding to the steel frame structure. A corrugated plate 11 is provided on one side of the inner side protective structure of the ground-connected wall foundation pit.

[0024] The ground-connected wall structure that does not require chiseling is reasonably designed in the utility model. By setting a hoisting steel bar structure and corrugated plates on the side, no subsequent chiseling is required, which optimizes the verticality of the ground-connected wall construction throughout the entire process, shortens the construction period, and ensures the stability and durability of the ground-connected wall.

[0025] Corrugated sheeting is typically made of galvanized steel, which offers excellent corrosion resistance. Under normal conditions, it boasts a service life of at least 30 years. Furthermore, the use of corrugated steel sheeting in high-altitude and permafrost regions demonstrates a service life of 50 to 100 years or more, with some structures still in use for over a century.

[0026] The structural design of the corrugated sheet ensures its long-term stability and durability. The sheet is formed into a wavy structure through cold rolling technology, which gives it extremely high rigidity and load-bearing capacity. Furthermore, the sheet's strong deformation adaptability allows it to effectively withstand external forces such as earthquakes, thereby enhancing the structure's seismic resistance.

[0027] Corrugated plates are used to separate the direct contact between concrete and soil wall. Due to the stability and durability of the corrugated plates, the strength of the concrete will not be diluted, so the concrete can be removed without chiseling.

[0028] The concrete rigid connection construction waterproof structure includes vertical reinforcement 1 welded by lifting rings, vertical reinforcement 2 of steel cage, horizontal truss reinforcement I3 and shear reinforcement 4. The horizontal truss reinforcement and shear reinforcement are all connected to the vertical reinforcement of steel cage and vertical reinforcement welded by lifting rings.

[0029] Furthermore, a continuous wall distribution reinforcement densification reinforcement structure is provided corresponding to the horizontal truss reinforcement, and the continuous wall distribution reinforcement densification reinforcement structure includes an upper continuous wall distribution reinforcement densification reinforcement 5 located at the upper part and a lower continuous wall distribution reinforcement densification reinforcement 6 located at the lower part; a rear vertical steel bar scaffold 7 is provided at the bottom of the concrete rigid connection construction waterproof structure; the verticality of the wall connection construction can be effectively guaranteed, and the construction period is shortened.

[0030] The inner protective structure of the ground-connected wall foundation pit consists of connected horizontal truss bars II 8 and diagonal truss bars 10. The corrugated plate is a vertically installed plate structure. Positioning pads 9 are installed at the ends of the diagonal truss bars, ensuring a stable and reliable structure. Connected hanging bars are installed corresponding to the horizontal truss bars II and the diagonal truss bars. After construction, the corrugated plate can be directly hoisted without chiseling, ensuring minimal resistance during hoisting and facilitating operation.

[0031] The above is only an illustration of a preferred embodiment of the present invention. The above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0032] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
