Description

Technical Field

[0001] The utility model belongs to the fields of civil engineering and construction, and in particular relates to a firmly connected HC method steel sheet pile. Background Art

[0002] HC method steel sheet piles are a new type of retaining construction pile method. They combine the characteristics of H-steel and Larsen steel sheet piles, and have the advantages of strong bending resistance, flexible construction, good economy, environmental protection, and little impact on the surrounding environment. HC method piles can be used as water-stop curtains, saving space occupied by retaining structures and speeding up construction. This type of pile method is suitable for various deep foundation pit retaining projects, such as building foundations, underpasses, pipeline corridors, high-speed railways, bridges, etc., and can provide stable support structures under different geological and hydrological conditions. The HC method steel sheet piles in the existing technology cannot effectively resist lateral loads and bending moments, and are prone to displacement or slippage during construction. In addition, there is a lack of sufficient limiting measures, making it difficult to ensure that the steel sheet piles maintain the correct position when subjected to external loads.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] Example: A firmly connected HC method steel sheet pile is composed of Figure 1-4 As shown, it includes Larsen steel sheet piles 1, H-shaped beams 2 and multiple H-shaped columns 3. Figure 4 As shown, four first through holes 13 are provided at the lower end of the H-shaped column 3, and the H-shaped column 3 is inserted into the Larsen steel sheet pile 1. Four fourth through holes 16 coaxial with the first through holes 13 are provided in the middle of the Larsen steel sheet pile 1. Four first pairs of through-limiting screws 4 are provided between the Larsen steel sheet pile 1 and the H-shaped column 3. The first pair of through-limiting screws 4 are inserted into the first through holes 13 and the fourth through holes 16 and fixed at both ends by nuts to ensure a stable connection between the Larsen steel sheet pile 1 and the H-shaped column 3. Figure 1 As shown, the H-shaped crossbeam 2 is erected above the H-shaped column 3 to enhance the lateral stability of the overall structure. Figure 2 As shown, the front and rear sides of the H-shaped column 3 are both provided with position-limiting connectors 6 fixed to the H-shaped crossbeam 2. Figure 3As shown, the limiting connector 6 includes a fixing plate 10, with first pressure blocks 11 provided on both sides of the upper end of the fixing plate 10 and second pressure blocks 12 provided on both sides of the lower end of the fixing plate. Bolt groups 9 are provided on the first and second pressure blocks 11, 12. The lower ends of the H-shaped crossbeam 2 are provided with multiple groups of first fixing holes 7 connected to the H-shaped columns 3, and the upper ends of the left and right sides of the H-shaped columns 3 are provided with multiple groups of second fixing holes 8 that cooperate with the first fixing hole groups 7. The bolt groups 9 are inserted into the first and second fixing hole groups 7, 8, and the bolt connection ensures the stability of the structure. A second pair of through-limit screws 5 is provided between the front and rear limiting connectors 6 of the H-shaped column 3. A second through hole 14 is provided in the middle of the upper end of the H-shaped column 3. A third through hole 15 coaxial with the second through hole 14 is provided in the middle of the fixing plate 10. The second pair of through-limit screws 5 pass through the second through hole 14 and the third through hole 15 in sequence, and are then fixed at both ends with nuts, ensuring a tighter connection between the H-shaped beam 2 and the H-shaped column 3. By using the first pair of through-limit screws 4 and the second pair of through-limit screws 5, the structure of this device makes the connection between the H-shaped column 3 and the Larsen steel sheet pile 1 and the H-shaped beam 2 more stable, thereby improving the stability and anti-displacement capability of the overall structure. Through the multi-point fixation between the H-shaped column 3 and the Larsen steel sheet pile 1 and the H-shaped beam 2, as well as the cooperation of the limiting connector 6, this device increases the structural stability of the entire structural connection and ensures the connection strength under various working conditions. In addition, the present device structure provides a more uniform and effective force transmission through the design of the limiting connector 6, such as the fixed plate 10, the first pressure block 11 and the second pressure block 12, thereby improving the overall performance of the connection. Since the present device structure adopts prefabricated parts and is connected by bolts, it reduces on-site operation time and labor costs, and also reduces material waste and additional costs that may be caused by processes such as welding. The bolted structure of the present device structure facilitates later inspection, maintenance and disassembly when necessary, reduces maintenance costs, and also facilitates the reuse or recycling of the structure. The present device structure ensures a tight connection between the components through the design of the limiting connector 6 and the fixing hole group, reduces the risk of structural loosening or displacement, and improves overall safety.
