[0030] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0031] Accordingly, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0032] Technical means not detailed in this application and not used to solve the technical problems of this application are set according to common general knowledge in the art, and multiple common general knowledge setting methods can be realized.

[0033] See Figures 1 to 8 , the trench sheet pile internal support device provided in this application for easy turnover and use includes: a fixed sleeve, a pair of movable struts 2, a plurality of packing members 8, and a pair of wedge blocks 9; an opening is provided at the extended end of the fixed sleeve, a resting member 5 is provided at the upper part of the open end, and slots are symmetrically provided on the fixed sleeve; the packing members 8 and the wedge blocks 9 are placed into the fixed sleeve through the slots and respectively abut against the movable struts 2 at both ends.

[0034] The resting member 5 is provided on the X surface of the fixed sleeve; the slots are symmetrically opened on the Y surface of the fixed sleeve; the X surface and the Y surface intersect perpendicularly. With this structure, it can be realized that the wedge blocks 9 are driven in from two opposite sides of the movable struts 2, improving the force reliability. With this structure, the support force greater than 10 tons required for trench sheet pile support can be satisfied.

[0035] In a specific embodiment, the fixed sleeve includes: a sleeve 4; first slots 71 and second slots 72 are symmetrically opened on two opposite side walls of the sleeve 4; the packing members 8 are sequentially passed through the first slots 71 and placed into the sleeve 4, and after rotation, the central axis of the packing member 8 coincides with the central axis of the sleeve 4. After a plurality of packing members 8 are stacked, a pair of wedge blocks 9 are driven into the gap between the last packing member 8 and the movable strut 2; the inclined surfaces of the pair of wedge blocks 9 are arranged oppositely, and the flat surfaces of the wedge blocks 9 respectively abut against the packing member 8 and one end of the movable strut 2. With this structure, the force is reliable and can meet the need for supporting the trench sheet pile.

[0036] During installation: the movable struts 2 are inserted into the sleeve 4 from both ends and then the device is lifted. The resting members 5 extending outward at both ends of the device are placed on the waling 12. A crowbar is used to pry the movable struts 2 outward at both ends at the position of the slots of the sleeve 4 until both ends of the movable struts 2 are closely attached to the outer waling 12. Then the packing members 8 are inserted into the slots of the sleeve 4, and a pair of wedge blocks 9 are driven into the gap between the last packing member 8 and the movable strut 2 to fix the position of the movable struts 2 in the sleeve 4, achieving the effect that the movable struts 2 respectively abut against the waling 12 at both ends.

[0037] During demolition: Apply force from the small-end side of the wedge block 9 to knock out the wedge block 9. Then, move the support rod 2 inward in the sleeve 4. When the outer end of the support rod 2 leaves the collar 12 and the contact is released, lift the device and then remove the sheet pile structure 11 of the trench.

[0038] In a specific embodiment, one such device is provided at intervals of 3 - 5 m along the extension direction of the collar 12 to achieve reliable support for the sheet piles of the trench.

[0039] Using this device can form multiple reliable support points on the inner side of the trench sheet piles during construction, ensuring that the distance between the collars remains unchanged during construction and meeting the design requirements. This device can be prefabricated and transported to the construction site by a crane. After being placed on the collar 12, the extended end of the movable support rod 2 is tightened against the collar 12 by inserting multiple packing pieces 8 and driving in the wedge block 9 to achieve the effect of internal support. This device has a good support effect, can prevent the change of the distance between the collars, and is conducive to improving construction efficiency.

[0040] In a specific embodiment, the packing pieces 8 are multiple round cakes. When blocking, the central axis of the packing piece 8 is arranged parallel to the central axis of the sleeve 4 to prevent the packing piece 8 from shifting inside the sleeve 4 and improve the reliability of blocking.

[0041] In a specific embodiment, the sheet pile structures 11 are arranged at relative intervals, and the collars 12 are symmetrically arranged on the upper part of the inner side walls of the sheet pile structures 11. The collars 12 are arranged above the support plate 1; one side of the support plate 1 is connected to the inner side wall of the sheet pile structure 11, and the other side extends outward.

[0042] In a specific embodiment, the shelving member 5 and the top surface of one end of the fixed sleeve are welded.

[0043] In a specific embodiment, it includes: a pair of lifting rings 6; the lifting rings 6 are fixedly connected to the outer side wall of the fixed sleeve and are arranged close to the shelving member 5. This arrangement can improve the stability during hoisting and transportation and the accuracy of placing the shelving member 5.

[0044] In a specific embodiment, according to the distance between the relatively arranged sheet pile structures 11 and the design requirements, the setting position of the slot on the fixed sleeve is determined by measurement and calculation so as to ensure that the two ends of the movable support rod 2 abut against the two side sheet pile structures 11.

[0045] In a specific embodiment, the outer diameter of the cross-section of the movable support rod 2 is 1 - 2 mm smaller than the inner diameter of the fixed sleeve. This arrangement facilitates the movement of the movable support rod 2 inside the sleeve 4.

[0046] In a specific embodiment, the cross-section of the wedge block 9 is a right trapezoid. One end of the wedge block 9 is the small end, and the other end is the wide large end. The two side walls of the wedge block 9 are inclined side walls and flat side walls. This arrangement can facilitate the driving in and knocking out of the wedge block 9 in the opening and improve the operation efficiency.

[0047] In a specific embodiment, the movable strut 2 includes: a first section and a second section. The first section is inserted into the sleeve 4; the second section extends out of the sleeve 4 and abuts against the waling 12. The length of the first section is greater than that of the second section. Such an arrangement facilitates the lifting of the device and prevents the movable strut 2 from disengaging during the lifting and transfer process.

[0048] In a specific embodiment, during installation, after the movable strut 2 is inserted into the sleeve 4 from both open ends, the device is lifted and transferred to the installation area. Then, the device is lowered and the resting members 5 at both ends of the device are placed on the waling 12. A crowbar is used to operate at the grooved position of the sleeve 4, and the movable struts 2 inserted on both sides are pried outwards towards both ends until both ends of the movable strut 2 are tightly attached to the waling 12 at both ends. Then, a stuffing member 8 is inserted into the grooved position of the sleeve, and a wedge block 9 is driven in to fix the extended length of the movable strut 2 and maintain the abutting state between both ends of the device and the waling 12.

[0049] During demolition, the wedge block 9 is knocked out. After the movable strut 2 automatically retracts into the sleeve 4 and moves away from the waling 12, the device is lifted by the lifting ring 6 and removed from the trench.

[0050] On the other hand, the present application also provides a trench sheet pile support structure, including: a sheet pile structure 11, a waling 12, a support plate 1, and a plurality of the above-mentioned devices; the sheet pile structures 11 are arranged in pairs opposite to each other; the upper parts of the opposite surfaces of the sheet pile structure 11 are provided with waling 12; the waling 12 extends along the extending direction of the sheet pile structure 11 and functions as a beam; the support plate 1 is arranged on the sheet pile structure 11 below the waling 12 and is perpendicularly connected to the sheet pile structure 11; one of the above-mentioned devices is arranged at intervals of 3 to 5 m; both ends of the above-mentioned device respectively abut against the side walls of the waling 12 to play a supporting role, realizing reliable support for the trench sheet pile. The device is arranged at the upper part of the trench sheet pile, facilitating transfer and removal according to construction needs, and realizing turnover use.
