[0026] Please continue reading Figures 1 to 3 As shown, in one embodiment of the present invention, the construction platform 3 is a steel grid. The steel grid can effectively resist the impact of waves.

[0027] Please continue reading Figures 4 to 10 As shown, in one embodiment of the present invention, the sand box assembly 4 includes a rectangular sand box 41 and a rectangular tube 42. A limit plate 43 is fixed to the top of the rectangular tube 42, and a sealing plate 44 is fixed to the bottom of the rectangular tube 42. The bottom of the rectangular tube 42 is sleeved in the rectangular sand box 41. A sand release hole 45 is provided at the bottom of the rectangular sand box 41. An internal thread is provided on the hole wall of the yarn release hole, and a bolt 46 is provided in the yarn release hole to engage with the internal thread. The rectangular sand box 41 is used as a support, and the rectangular sand box 41 support is welded to the steel casing. The front and rear sides are continuously fully welded, and the weld height is 8 mm. The sand is poured into the sand box by re-measurement of the elevation, and the dry fine sand is filled and vibrated to make it dense. Figure 4 and Figure 5The granular object therein is fine sand. The height of each sand box is the same. When the bottom mold and the supporting steel section are removed, it is only necessary to slowly empty the sand in the sand box, so that it is not necessary to use a lifting tool to hang the bottom mold support beam 1 upside down on the pile cap, optimizing the construction steps, reducing potential safety hazards and improving the safety factor.

[0028] Please continue to refer to Figure 6 As shown, in an embodiment of the present utility model, extension parts 47 are provided on both the left and right sides at both ends of the rectangular sand box 41. The extension parts 47 can increase the contact area between the sand box assembly 4 and the bottom mold support beam 1, improving the safety factor.

[0029] Please continue to refer to Figure 5 and Figure 6 As shown, in an embodiment of the present utility model, the size of the sealing plate 44 is the same as the inner shape of the bottom of the rectangular pipe 42, and the length and width of the limiting plate 43 are the same as the length and width of the rectangular sand box 41.

[0030] Please continue to refer to Figures 1 to 2 As shown, in an embodiment of the present utility model, guardrails 6 are fixed at the edges of the steel bottom mold 2 and the construction platform 3. The guardrails 6 can be directly installed along the outer edge of the steel bottom mold 2. During the laying process of the steel bottom mold 2, the operators are all working on the steel bottom mold 2 or the steel grid construction platform 3 board with protective facilities, which is fast and safe.

[0031] Please continue to refer to Figures 1 to 2 As shown, in an embodiment of the present utility model, an opening matching the high-pile wharf pile 5 is provided at the middle position inside the steel bottom mold 2. The steel bottom mold 2 is a 10-mm-thick steel plate, and the steel bottom molds 2 on both sides of the high-pile wharf pile 5 are symmetrically distributed along the pile axis of the vertical cross beam of the high-pile wharf pile 5. The opening matches the high-pile wharf pile 5, enabling stable installation.

[0032] Please continue to refer to Figures 1 to 2 As shown, in an embodiment of the present utility model, the bottom mold support beams 1 on both sides are fixedly connected by steel pipes. The steel pipes are fastened with limit bolts or fixed by welding to prevent them from falling off due to wave impact.

[0033] The utility model operates according to the following principles: The rectangular sand box supports are directly welded to the steel casing of the cast-in-place pile, with continuous full welds on both sides and a weld seam height of 8mm. Slight deviations in the sand box weld elevation are inevitable, so the filling elevation should be remeasured and marked before and after sand filling. Dry fine sand is preferred for filling the sand box and should be compacted after filling to minimize settlement. A 5mm to 10mm allowance should be allowed for settlement within the sand box, and re-compacting is required after adding or removing fine sand. The bottom formwork support beam 1 is supported on the top surface of the sand box and secured with limit bolts or welds (with steel pipes between) to prevent dislodging due to wave impact. After the first steel bottom formwork is initially positioned, a person unhooks it. Using the first steel bottom formwork as a construction platform, the second steel bottom formwork is precisely positioned. The first steel bottom formwork is then precisely positioned and the locking bolts at both ends are tightened. The steel grid construction platform plate (with a 1.2m high protective railing installed along the outer edge) and the second pile cap steel bottom formwork are then laid. During the steel base formwork installation process, workers should work on a steel base formwork or steel grid construction platform equipped with protective railings. When removing the base formwork and supporting steel, simply drain the sand from the sand box slowly. If the fine sand does not flow out naturally, flush it out with a water pipe through the sand drain hole. After removal, hoist the first pile cap steel grid construction platform, the base formwork, the second pile cap steel grid construction platform, and so on. The hoisted steel grid construction platform and base formwork are then transferred directly to the next construction unit.

[0034] The above description is only a preferred embodiment of the present invention and should not be understood as limiting the present application. All equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
