Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments. Example

[0015] like Figure 2-7As shown, the quick-release and quick-install waler support provided by this utility model includes: a connector 5 installed on the waler 2 and a hook 11 installed on one side of the sheet pile 1. The hook 1 is fixed to a recessed area on one side of the sheet pile 1 by welding, bolts, or other means, and the hook 11 does not protrude from the side of the sheet pile 1, so it will not affect the transportation of the sheet pile 1 and therefore does not need to be removed. One end of the connector 5 is movably connected to the waler 2, and the other end is hung on the hook 11, thereby forming an oblique pulling force on the waler 2, so that the waler 2 is pressed tightly against the side of the sheet pile 1 and remains stable. It is worth noting that there are multiple hooks 11 and connectors 5, and the number of hooks 11 is greater than the number of connectors 5, and the multiple hooks 11 are arranged in multiple layers. Multiple fixing parts 21 are installed on the waler 2. Figure 2 The number of connectors 5 installed on one of the walers 2 is for illustrative purposes only; the actual number should be greater than three. The connector 5 includes a threaded sleeve 51, with two screws 52 of opposite threads installed at each end of the threaded sleeve 51. A hook 53 is installed at one end of each screw 52. One hook 53 is connected to the fixing member 21 installed on the waler 2, and the other hook 53 is hung on the hook 11. After the foundation pit is excavated, several sheet piles 1 are inserted around the perimeter of the pit to support the pit walls, except for the cable tunnel entrance. Then, using a lifting device, the two wire ropes of the lifting device are connected to the hooks 53 near the ends of the walers 2. The walers 2 are lifted and placed close to the sheet piles 1. The remaining empty hooks 53 of the walers 2 are hung on the nearest hooks 11. The wire ropes are then released, and the walers 2 are vertically supported using multiple connectors 5. The remaining walers 2 are fixed in the same way. Based on the height difference between the walers 2 directly opposite each other, the height of one side of the walers 2 is adjusted to align the heights of the walers 2 facing the pit front-to-back and left-to-right. The walers 2 positioned front-to-back and left-to-right should be staggered in height to prevent the steel pipe supports 4 from being unable to be installed. Rotating the threaded sleeve 51 allows the screws 52 at both ends to move closer or further apart, thereby adjusting the height of the walers 2. Then, multiple steel pipe internal supports 4 are used to horizontally brace the two opposing walers 2 from the inside. During disassembly, the steel pipe internal supports 4 are removed first, then the walers 2 are lifted and moved out of the foundation pit, and finally the steel sheet piles 1 are removed. There is no need to remove the hooks 11. Compared with the traditional corbel 3 support method, this method can effectively improve work efficiency and make the operation more convenient.

[0016] By installing multiple hooks 11 on the sheet pile 1 and multiple connectors 5 on the waler 2, the construction and fixing of the sheet pile 1 can be facilitated, and the installation and disassembly of the connectors are more convenient and quick, which helps to improve the construction speed. By setting the connectors 5, which include threaded sleeves 51, screws 52 and hooks 53, the hoisting of the waler 2 can be facilitated, and the installation height of the waler 2 can be easily adjusted. Example

[0017] like Figure 4As shown, in this embodiment, an anti-loosening nut 521 is installed on the screw 52. In use, the anti-loosening nut 521 is rotated so that one end of it is tightly attached to the threaded sleeve 51, thereby preventing the screw 52 from rotating.

[0018] By installing an anti-loosening nut 521 on the screw 52, ​​the screw 52 can be prevented from rotating. Example

[0019] like Figure 2 and Figure 5 As shown, the fastener 21 includes a support plate 211, which is fixed to the waler 2. A connecting ear 212 is slidably installed on the support plate 211. The connecting ear 212 is connected to the corresponding hook 53 (they pass through each other, i.e., they are interlocked). In use, there may be a situation where the hook 11 and the connecting ear 212 cannot be aligned. In this case, the connecting ear 212 can be slid laterally to adjust its position so that it is aligned with the hook 11. Then, the fastener 5 can be easily connected to the hook 11.

[0020] By setting up a support plate 211 and installing an adjustable connecting ear 212 on the support plate 211, the installation of the connector 5 can be facilitated. Example

[0021] like Figure 6-7 As shown, a mounting groove 2111 is formed on the support plate 211, and a slider 2112 is installed in the mounting groove 2111. The slider 2112 slides along the mounting groove 2111, and the top end of the slider 2112 is fixedly connected to the connecting ear 212. This achieves a sliding connection between the connecting ear 212 and the support plate 211.

[0022] By setting the mounting groove 2111 and installing the slider 2112 in the mounting groove 2111, a sliding connection between the connecting ear 212 and the support plate 211 can be achieved. Example

[0023] like Figure 7 As shown, the connecting ear 212 is installed at an angle on the top of the slider 2112. Its angle of inclination is adapted to the angle of inclination when the connector 5 is installed. That is, the connecting ear 212 is designed to be tilted towards the hook 11. This makes the force direction of the connecting ear 212 basically consistent with its bending direction and angle when the connector 5 pulls the connecting ear 212, making it less likely to bend the connecting ear 212 and thus improving the service life of the connecting ear 212.

[0024] By setting the connecting ear 212 to be installed at an angle on the top of the slider 2112, it is beneficial to prevent the connecting ear 212 from being bent during use, which helps to improve its service life.

[0025] Working Principle: After excavation, several sheet piles 1 are inserted around the perimeter of the pit to support the pit walls, except for the cable tunnel entrance. A lifting device is then used, with its two wire ropes connected to hooks 53 near the ends of the walers 2. The walers 2 are lifted and placed close to the sheet piles 1. The remaining free hooks 53 of the walers 2 are hung on the nearest hooks 11. The wire ropes are then released, and the walers 2 are vertically supported using multiple connectors 5. The remaining walers 2 are fixed in the same way. The height of one side of the walers 2 is adjusted based on the height difference between the walers facing it, ensuring alignment of the walers in the front, back, left, and right directions. The walers 2 should be staggered in height to prevent the internal support 4 from being unable to be installed. Rotating the threaded sleeve 51 moves the screws 52 at both ends closer or further apart, thus adjusting the height of the walers 2. Then, multiple steel pipe internal supports 4 are used to horizontally brace the two opposing walers 2 from the inside. During disassembly, the steel pipe internal supports 4 are removed first, then the walers 2 are lifted and moved out of the foundation pit, and finally the steel sheet piles 1 are removed. There is no need to remove the hooks 11. Compared with the traditional corbel 3 support method, this method can effectively improve work efficiency and make the operation more convenient.
