the manufacturing method comprises the following steps: firstly, a measurer discharges a cavity position on a bottom die of a prefabricated part according to an actual pile position on site, a rubber dovetail grout stopping strip is laid and fixed along the paying-off position, then the rubber dovetail grout stopping strip is fixed at the positions of two side slopes of the rubber dovetail grout stopping strip at intervals of 10cm, and a special release agent is coated on the outer slope of the rubber dovetail grout stopping strip, so that the prefabricated part is prevented from being adhered to the bottom die plate in the later period of transportation; secondly, manually stacking the steel corrugated culvert pipes on the dovetail grout stop strips, embedding the bottom openings of the steel corrugated culvert pipes at the grooves of the dovetail grout stop strips, and sealing the rubber dovetail grout stop strips by adopting foam rubber to prevent grout leakage in the concrete pouring process; and finally, installing a top steel cover plate, leveling the steel cover plate through the leveling support, welding along the top opening of the corrugated steel culvert pipe, and brushing polyurethane sealant at the position of a welding side opening to prevent slurry leakage.
The technical problem to be solved by the invention can be further realized by the following technical scheme that the top steel plate cover is 10mm thick, the embedded steel bars are 1700mm high, and 2 grouting holes are formed.
Compared with the prior art, the invention has the beneficial effects that:
(1) compared with the existing inner cavity template mounting process, the cavity dismantling-free chiseling structure reduces the component hoisting operation times and can effectively reduce the safety risk.
(2) Compared with the existing inner cavity template, the installation accuracy of the cavity dismounting-free chiseling structure is higher.
(3) Compared with the existing cavity joint construction, the construction of the cavity dismantling-free chiseling structure reduces the construction steps and reduces the installation difficulty.
(4) Compared with the existing inner cavity template, the integral template joint has high rigidity, good stability and good overall effect. The construction precision can be effectively improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, and in order to make those skilled in the art understand the present invention further, the embodiments of the present invention will be described in detail and fully with reference to the accompanying drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A cavity node mould-removal-free scabbling structure of a prefabricated member of an assembled high-pile wharf, which is efficient and safe in construction and does not need to be put into use for many times, and a construction method thereof. Is assembled by 3 parts and comprises a rubber dovetail grout stopping strip 5, a steel corrugated culvert pipe 4 and a top steel cover plate 3. The bottom of the rubber dovetail grout stopping strip of the structure is paved with grout stopping, a cavity is reserved in the upper portion of the installation steel corrugated culvert pipe, and the top of the installation steel corrugated culvert pipe is welded with a steel cover plate to form an airtight integral structure, so that the structure is convenient and fast.
The top steel plate cover is 10mm thick, and the planting bar 2 is 1700mm high, and is equipped with 2 grout holes 1.
Taking a prefabricated part reserved with a cavity node of 1.6m as an example, the width of a bottom opening of a rubber dovetail grout stopping strip is 100mm, the height of the rubber dovetail grout stopping strip is 66mm, the width of a groove at a top opening of the rubber dovetail grout stopping strip is 16mm, and the height of the groove is 15 mm; the diameter of the steel corrugated culvert pipe is 1600mm, the wall thickness is 5mm, the corrugation distance is 150mm, and the corrugation height is 30 mm; the steel cover plate is planted with the steel bars of 1700mm, the thickness is 10mm, 2 grouting holes with the diameter of 200mm are reserved, and the upper part is provided with the anchoring steel bars.
The manufacturing method comprises the following steps: firstly, a measurer discharges a cavity position on a bottom die of a prefabricated part according to an actual pile position on site, a rubber dovetail grout stopping strip is laid and fixed along the paying-off position, then the rubber dovetail grout stopping strip is fixed at the positions of two side slopes of the rubber dovetail grout stopping strip at intervals of 10cm, and a special release agent is coated on the outer slope of the rubber dovetail grout stopping strip, so that the prefabricated part is prevented from being adhered to the bottom die plate in the later period of transportation; secondly, manually stacking the steel corrugated culvert pipes on the dovetail grout stopping strips, embedding the bottom openings of the steel corrugated culvert pipes into grooves of the dovetail grout stopping strips, and sealing the rubber dovetail grout stopping strips by adopting foam rubber to prevent grout leakage in the concrete pouring process; and finally, installing a top steel cover plate, leveling the steel cover plate through the leveling support, welding along the top opening of the corrugated steel culvert pipe, and brushing polyurethane sealant at the position of a welding side opening to prevent slurry leakage.
The next construction can be directly carried out after the finished product processing, and the later period of the inner wall of the cavity of the prefabricated part can be free from chiseling construction due to the existence of the steel corrugated culvert pipe.
The length and width of the inner side of the integral pile cap template are larger than the length and width of the pile cap reinforcement cage, so that the integral pile cap template can be smoothly sleeved into the pile cap reinforcement cage.
The splicing and assembling of the integral template are completed in the back field, and the integral template is transported to a construction site by a barge to be integrally filled with the template and demoulded.
