Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a column-combined steel sheet pile. Background Technology

[0002] Steel sheet piles are interlocking steel structural members with various cross-sectional shapes, including U-shaped, Z-shaped, straight, and CAZ-shaped. They are easy to install, driven into the soil using a hydraulic vibratory hammer. Their advantages include light weight, adaptability to narrow foundation pit support environments, relatively small earthwork volume during construction, and the interlocking joints with grooves on both sides, forming a sheet pile wall with good waterproofing and high strength, effectively retaining soil and water outside the foundation pit during construction. After completion, they can be extracted from the soil and reused, making them an excellent green building material. Therefore, steel sheet piles will be widely used in the construction of small and medium-sized foundation pits in the future.

[0003] However, steel sheet piles still encounter some difficulties in their application. First, they are difficult to drive into soil layers with high strength or are prone to deformation. Second, the water tightness of steel sheet piles is compromised due to construction reasons. They are not widely used in deep foundation pits and are mostly used as an auxiliary measure. Summary of the Invention

This column-combined steel sheet pile structural design solves the problem of driving into high-strength soil layers and avoids the deformation problem of the steel sheet pile.

[0031] Example 1:

[0032] refer to Figures 1 to 4 As shown in the figure, a column-combined steel sheet pile is illustrated. The combined steel sheet pile includes several columns 1 and steel sheet pile pieces 2 disposed between adjacent columns 1.

[0033] The column 1 has an axially oriented groove 14 on its side wall, and the sheet pile 2 is engaged within the groove 14. The sheet pile 2 is made of Larssen steel sheet pile. The column 1 is a steel structure.

[0034] In a preferred embodiment, when the column-combined sheet pile is a double-layer structure, such as Figure 1 As shown, the composite steel sheet piles of each layer of columns are connected by partition plates 3.

[0035] Preferably, an expansion sealing strip is also provided between the slot 14 and the sheet pile 2. The expansion sealing strip improves the water-tightness of the column-combined sheet pile of the present invention.

[0036] Furthermore, the column 1 has four slots 14 on its side wall, and each slot 14 is set at an equal angle around the side wall.

[0037] Preferably, the top side wall of the column 1 is provided with a plug-in hole 11. When the column-type sheet pile is used up and needs to be dismantled, the connecting end of the corresponding plug-in mechanism is inserted into the plug-in hole 11, which helps to quickly pull out the column and will not damage the side wall of the column 1.

[0038] Preferably, the middle part of the column 1 is further provided with a transmission layer 12 to provide power. This transmission layer 12 is modeled after the principle of a relay station, providing the sheet pile with a miniature relay station-like vibration, making it easier to drive the sheet pile. The transmission layer is a freely retractable chamber, and the retractable connecting rod is driven by the transmission jack, allowing it to extend and retract freely up and down, similar to a miniature relay station, thus increasing the main force.

[0039] Specifically, the transmission layer 12 includes a shock-absorbing chamber 121, which is equipped with a plurality of vibrators 122 to drive the column 1 to reciprocate in the axial direction.

[0040] Preferably, the vibrator 122 is a micro frequency-modulated vibrator that utilizes the resonance principle. When working, the frequency is modulated to about 30 Hz, which is close to the soil frequency, thereby loosening the soil and avoiding the frequency of about 70-100 Hz of the steel pipe. This can increase the vibration amplitude of the surrounding soil and reduce the impact on the column 1. A shock-absorbing chamber 121 is set in the transmission layer to reduce the impact on the bidirectional transmission jack 123.

[0041] Preferably, the transmission layer 12 further includes a bidirectional transmission jack 123, a first telescopic rod 124, and a second telescopic rod 125. The bidirectional transmission jack 123 is disposed inside the shock absorption chamber 121, and both ends of the bidirectional transmission jack 123 are respectively connected to the first telescopic rod 124 and the second telescopic rod 125. The first telescopic rod 124 and the second telescopic rod 125 are respectively connected to the first end and the second end of the column 1.

[0042] Preferably, the column 1 has a transmission line hole 13 at its center, through which the control lines of the vibrator 122 and the bidirectional transmission jack 123 are connected to the vibrator 122 and the bidirectional transmission jack 123 respectively.

[0043] Preferably, the shock-absorbing chamber 121 is filled with a flexible shock-absorbing medium. Further, the shock-absorbing chamber 121 can be made of a loose, porous material such as a solid sponge to absorb energy and prevent the vibrator from affecting the bidirectional transmission jack 123.

[0044] During the installation of sheet piles, if a hard stratum is encountered and the end hydraulic machinery has difficulty driving the piles in, the transmission layer 12 can be opened at the control center on the ground. After the transmission layer 12 is opened, the end hydraulic machinery stops driving as a backup. The bidirectional transmission jack 123 applies downward pressure, which drives the sheet pile pieces in the slot 14 downward through the column. At the same time, the vibrator 122 is turned on to loosen the surrounding soil. When the jack moves about 10cm, the operation of the transmission layer 12 is stopped. Then, the specialized machinery drives the piles downward. The telescopic connecting rod will close, and the transmission layer 12 will return to its original state.

[0045] If necessary, the above process can be repeated, and additional transmission layers 12 can be added.

[0046] When extracting the sheet piles, try to detach the soil beneath them before extracting the piles (column 1). Specifically, first, start the vibrator 122 of the transmission layer 12 to loosen the surrounding soil. Then, in conjunction with the bidirectional transmission jack 123 inside the chamber, perform the reverse process of driving. The bidirectional transmission jack 123 moves upward, exerting upward force together with the hydraulic sheet pile extractor at the end. First, extract the sheet piles 1-2 meters higher. Then, extract all the sheet piles 1-2 meters higher in sequence to loosen them before extracting them one by one. For piles with curled tips or deformed interlocking joints, increase the capacity of the extraction equipment to extract adjacent piles at the same time.

[0047] This invention introduces a column connection slot into the composite sheet pile, optimizing the interface of the sheet piles and making the assembly of sheet piles more convenient and faster. Furthermore, the column slot design greatly facilitates the construction of double-layer sheet piles and allows for the connection of multiple layers of sheet piles into a single unit, comprehensively improving the rigidity of the sheet piles.

[0048] The present invention's column-combined steel sheet pile has a built-in vibrator 122 and a bidirectional transmission jack 123 in the column, which can serve as an intermediate power source to facilitate the insertion and extraction of the steel sheet pile in the hard layer, avoiding structural damage caused by forcibly striking or pulling it out from the end. Furthermore, the column and steel sheet pile of the present invention can be completely recycled, enabling multiple reuses.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
