Description

Technical Field

[0001] The invention relates to the field of pipe curtain construction, and in particular to a large-diameter pipe curtain connection structure for composite stratum construction. Background Art

[0002] In civil engineering construction, especially when developing underground space under composite stratum conditions, pipe curtain construction technology has been widely used as an important underground excavation technology. Pipe curtain construction method, also known as pipe jacking method, is a new underground excavation technology that realizes stable excavation of underground space by using a pipe curtain structure formed by connecting a large number of steel pipes. However, under composite stratum conditions, due to the complex and changeable geological conditions, pipe curtain construction faces many challenges.

[0003] Composite strata usually refer to strata structures formed by the interlacing and superposition of multiple rock and soil layers of different properties. Under such stratum conditions, the connection strength between steel pipe columns in pipe curtain construction becomes a key factor affecting the overall stability of the pipe curtain. At present, the connection methods between steel pipe columns in pipe curtain construction mainly include welding and bolt connection, but in actual construction, due to factors such as construction conditions and improper operation process, the connection strength between steel pipe columns is insufficient, which seriously affects the strength of the overall connection structure of the pipe curtain. Summary of the invention

[0004] In order to strengthen the connection strength between two adjacent steel pipe columns and improve the overall structural stability of the pipe curtain, the present application provides a large-diameter pipe curtain connection structure for composite stratum construction.

[0005] The large-diameter pipe-roof connection structure for composite stratum construction provided in this application adopts the following technical solution:

[0006] A large-diameter pipe curtain connection structure for composite stratum construction includes a connecting plate. The connecting structure is used in conjunction with the pipe curtain. The pipe curtain includes a plurality of steel pipe columns arranged along a predetermined construction direction. Each of the steel pipe columns is provided with mounting holes at both ends along the width direction of the pipe curtain. The connecting plate is plugged into the plurality of steel pipe columns through the mounting holes on the plurality of steel pipe columns.

[0007] By adopting the above technical solution, first, the connecting plate connects multiple steel pipe columns into an integral pipe curtain structure, which significantly improves the connection strength of the pipe curtain. This connection method can resist various forces and moments brought by complex geological conditions in composite formations, ensuring the stability and safety of the pipe curtain structure; second, the connection structure adopts a plug-in method to connect steel pipe columns, which is simple and convenient to construct, reducing the construction difficulty and cost. At the same time, the design of the connecting plate is also convenient for on-site installation and adjustment, improving construction efficiency; third, the connection structure is suitable for the connection of steel pipe columns of different diameters and lengths, and has strong adaptability. In the construction of composite formations, appropriate steel pipe columns and connecting plate specifications can be selected according to actual conditions to meet different construction needs.

[0008] Preferably, a pair of connecting blocks are respectively provided at both ends of the segment of the connecting plate located in each of the steel pipe columns in the height direction of the pipe curtain, and the two connecting blocks of the same pair are slidably installed with anchor rods, and a driving assembly for driving the two anchor rods of the same pair to slide in a direction away from the connecting plate is installed on the connecting plate; an anchor hole is provided on the side wall of the steel pipe column, and one end of the anchor rod away from the connecting block is passed through the anchor hole and is inserted into the steel pipe column, and one end of the anchor rod passing through the steel pipe column is buried in the earth.

[0009] By adopting the above technical solution, first, the connection plate is tightly connected to the steel pipe column and the surrounding earthwork through the anchor rod, forming a more stable overall structure; this helps to resist the various forces and moments brought by the complex geological conditions in the composite strata, and improve the stability and safety of the pipe curtain structure; second, the anchor rod can slide on the connection block to adapt to the steel pipe columns and earthwork at different spacings. This design makes the connection structure more adaptable and can adapt to different geological conditions and construction requirements; third, due to the close connection between the connection structure and the steel pipe column and earthwork, the problems of loose connection and looseness that may occur in the traditional connection method are avoided. At the same time, the inspection of the connection quality is also more convenient and accurate, which helps to improve the construction quality.

[0010] Preferably, the driving assembly includes a driving block and a first bidirectional threaded rod, the driving block is provided on each of the anchor rods, and different threaded sections of the first bidirectional threaded rod are respectively threadedly connected to the driving blocks on the two connecting blocks of the same pair.

[0011] By adopting the above technical solution, first, by using the first bidirectional threaded rod, the two anchor rods of the same pair can be easily adjusted at the same time, thereby improving the adjustment efficiency; this helps to quickly complete the adjustment of the anchor rods at the construction site, saving time and labor costs; second, since the first bidirectional threaded rod can accurately control the sliding distance of the anchor rod, the stability of the connection structure during the adjustment process can be ensured; this helps to avoid loosening or damage of the connection structure due to improper adjustment, thereby improving the overall stability of the pipe curtain structure.

[0012] Preferably, outer side walls at both ends of the steel pipe column along the width direction of the tube curtain are respectively provided with C-shaped pieces and T-shaped pieces, and the T-shaped piece on one steel pipe column is inserted into the adjacent steel pipe column through the C-shaped piece on the adjacent steel pipe column.

[0013] By adopting the above technical solution, firstly, a more solid connection structure is formed between adjacent steel pipe columns through the plug-in connection of C-shaped parts and T-shaped parts. This connection method can effectively resist various forces and moments brought by complex geological conditions in composite strata, and improve the overall stability and safety of the pipe curtain structure; secondly, the plug-in connection method of C-shaped parts and T-shaped parts has strong adaptability. Whether it is the connection requirements of steel pipe columns of different diameters or different angles, they can be met by adjusting the position and angle of C-shaped parts and T-shaped parts, so that the connection structure can adapt to different geological conditions and construction requirements.

[0014] Preferably, the T-shaped member includes a pair of first angle steels arranged up and down in a vertical direction, and one end of each of the first angle steels is connected to one of the steel pipe columns, and the other end extends toward a direction away from the other angle steel of the same pair; the C-shaped member includes a pair of second angle steels arranged up and down in a vertical direction, and one end of each of the second angle steels is connected to one of the steel pipe columns, and the other end extends toward a direction close to the other second angle steel of the same pair, and a connecting groove for inserting the two first angle steels is formed between the two second angle steels.

[0015] By adopting the above technical solution, the production and installation of T-shaped pieces and C-shaped pieces are relatively simple, and the construction workers only need to weld or bolt them according to the designed size and angle. At the same time, due to the plug-in matching method between them, the connection process is more convenient and quick, which improves the construction efficiency.

[0016] Preferably, a pouring cavity is formed between the two first angle steels of one steel pipe column and the two second angle steels of an adjacent steel pipe column, and the pouring cavity is used for pouring concrete.

[0017] By adopting the above technical solution, a pouring cavity is formed between the T-shaped member and the C-shaped member and poured with concrete, which can further strengthen the connection strength between the two steel pipe columns. The presence of concrete can resist forces and moments from all directions, thereby improving the stability and safety of the entire pipe curtain structure.

[0018] Preferably, a second bidirectional threaded rod is provided between two adjacent steel pipe columns, and one end of the second bidirectional threaded rod is passed through a side plate of the first angle steel, and the other end is passed through a corresponding side plate of the second angle steel.

[0019] By adopting the above technical solution, the second two-way threaded rod is inserted into the side plates of the first angle steel and the second angle steel, providing an additional connection point between the two steel pipe columns. This increases the stability and shear resistance of the connection, and helps to resist the complex stress and deformation in the stratum; the use of the second two-way threaded rod for connection does not require a complicated welding or bolt connection process, and only requires pre-drilling holes in the first angle steel and the second angle steel, which is convenient for workers to carry out connection construction.

[0020] Preferably, the connecting plate is penetrated through each of the adjacent C-shaped members and the T-shaped members through each of the perfusion cavities.

[0021] By adopting the above technical solution, the connecting plate is inserted into the pouring cavity. After the concrete is poured into the pouring cavity, the connecting plate segment at that location is connected to the C-shaped piece and the T-shaped piece, thereby improving the stability of the connecting plate and reducing the slippage of the connecting plate along the width direction of the pipe curtain.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The connecting plate connects multiple steel pipe columns into an integral pipe curtain structure, significantly improving the connection strength of the pipe curtain. This connection method can resist various forces and moments brought by complex geological conditions in composite strata, ensuring the stability and safety of the pipe curtain structure; secondly, the connection structure uses plug-in connection to connect steel pipe columns, which is simple and convenient to construct, reducing the construction difficulty and cost;

[0024] 2. The connection structure uses plug-in to connect steel pipe columns, which is simple and convenient to construct, reducing the construction difficulty and cost. At the same time, the design of the connection plate is also convenient for on-site installation and adjustment, improving construction efficiency; third, the connection structure is suitable for connecting steel pipe columns of different diameters and lengths, and has strong adaptability. In the construction of composite formations, appropriate steel pipe columns and connection plate specifications can be selected according to actual conditions to meet different construction needs.
