Description

Technical Field

[0001] The utility model belongs to the technical field of anti-corrosion of pipe pile heads, in particular to a device for preventing leakage by painting the head of a PHC pipe pile. Background Art

[0002] In recent years, with the implementation of the national new energy policy, photovoltaic projects have gradually increased. Most photovoltaic support foundations use cast-in-place piles and PHC prestressed pipe piles. Since the concrete cast-in-place piles need to solidify, the construction period is long, and the quality of the concrete cast-in-place piles cannot be effectively controlled. After completion, pile foundation testing is required, which greatly affects the construction cost. Compared with PHC prestressed pipe piles, PHC pipe piles can effectively improve construction efficiency, shorten construction period, and reduce construction costs. Therefore, PHC pipe piles (prestressed high-strength concrete pipe piles) are increasingly widely used in photovoltaic support foundations. PHC pipe piles are mostly used in swamps, river beaches, fish ponds and other areas with relatively high underground moisture content in high-cold areas. Due to the high air humidity in the construction area, the iron parts of the pile heads are prone to rust, and manual anti-corrosion operations are required, which increases the construction period and cost.

[0003] During the construction of PHC pipe piles, manual anti-corrosion painting is required on the pile heads, which results in slow construction efficiency and the quality cannot be guaranteed, which affects the construction period, quality and cost of the project to a certain extent.

[0004] In this context, it is very necessary to study a device for preventing leakage by painting the head of PHC pipe piles, which can be used in anti-corrosion operations in conjunction with manual labor to effectively improve construction efficiency and anti-corrosion quality. Utility Model Content

[0005] In view of the above background technology, in order to overcome the defects of existing construction technology, the utility model provides a device for preventing leakage of paint on the head of a PHC pipe pile, which solves the problems of paint leaking from the pile head to the pile body during the anti-corrosion period, affecting the appearance and slowing down the construction efficiency.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a device for preventing leakage by painting the pile head of a PHC pipe pile, which is composed of two identical semicircular structures, the semicircular structure comprising a half-upper tray and a half-lower tray, the half-upper tray and the half-lower tray are both semicircular rings, and the centers of the half-upper tray and the half-lower tray are on the same vertical line, and the outer diameter of the half-upper tray is larger than the outer diameter of the lower half tray; a semi-cylinder is installed at the bottom of the half-upper tray, and the inner side wall of the semi-cylinder is fixed to the outer side surface of the half-lower tray; the half-lower tray is filled with sponge; and a semi-cylindrical tray outer edge plate is installed on the outer side surface of the half-upper tray; one end of the semi-upper trays of the two semi-circular structures is hinged, and the other end is connected by a locking device, and the two semi-circular structures can be disassembled or fixed together by the bolts on the locking device.

[0007] Preferably, a rib is installed below the semicircular structure, and the upper end of the rib is fixedly connected to the bottom of the semi-upper tray and the bottom of the semi-lower tray. The rib is used to support the semi-upper tray and the semi-lower tray to prevent the tray from deforming.

[0008] Preferably, the sponge is a finished sponge strip, which is convenient for replacement.

[0009] Preferably, the bottom of the half-upper tray and the semi-cylinder, the inner side wall of the semi-cylinder and the outer side surface of the half-lower tray, and the outer side surface of the half-upper tray and the outer edge plate of the semi-cylindrical tray are all connected by welding.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Example 1

[0015] like Figure 1-2As shown, a device for preventing leakage by painting the pile head of a PHC pipe pile is composed of two identical semicircular structures, the semicircular structure comprising a half upper tray 1 and a half lower tray 3, both of which are semicircular rings, and the centers of the half upper tray 1 and the half lower tray 3 are on the same vertical line, and the outer diameter 1 of the half upper tray is larger than the outer diameter of the lower half tray 3; a semi-cylinder 4 is installed at the bottom of the semi-upper tray 1, and the inner side wall of the semi-cylinder 4 is fixed to the outer side of the semi-lower tray 3; the semi-lower tray 3 is filled with sponge strips; a semi-cylindrical tray outer edge plate 5 is installed on the outer side of the semi-upper tray 1; one end of the semi-upper trays of the two semi-circular structures is hinged by a pin 6, and the other end is connected by a locking device 7, and the two semi-circular structures can be disassembled or fixed together by the bolts on the locking device 7.

[0016] Three ribs 2 are installed under each of the semicircular structures, and the upper ends of the ribs 2 are fixedly connected to the bottom of the semi-upper tray 1 and the bottom of the semi-lower tray 3. The ribs 2 are used to support the semi-upper tray and the semi-lower tray to prevent the tray from deforming.

[0017] The bottom of the half upper tray 1 and the semi-cylinder 4, the inner side wall of the semi-cylinder 4 and the outer side of the half lower tray 3, and the outer side of the half upper tray 1 and the outer edge plate 5 of the semi-cylindrical tray are all connected by welding.

[0018] The unexplained parts involved in the present invention, such as the structure of the locking device, are conventional technical means in the field and will not be described in detail here.

[0019] In this embodiment, two half upper trays 1 are used to collect excess paint, and the inner diameters of the half upper tray 1 and the half lower tray 3 are consistent with the outer diameter of the pipe pile.

[0020] The utility model is applied to the anti-corrosion work of the end plate of the pile head of the PHC pipe pile. The original construction personnel used paper tape wrapped around the lower edge of the end plate to prevent the paint from dripping on the pile body. After the end, the paper tape needs to be torn off. This original method is cumbersome to construct and has low construction efficiency. The utility model uses a locking device to lock the unhinged end of the two semicircular structures through the bolts on the locking device, and the device can be fixed under the end plate to protect the end plate at the pile head position. The upper tray composed of two half upper trays 1 can effectively collect excess anti-corrosion paint to prevent excess paint from dripping. In order to prevent secondary leakage at the gap between the tray and the pile body, the sponge suction strip filled in the lower tray composed of two half lower trays absorbs the leaked paint, and a rib plate is arranged on the lower side of the tray to fix the tray. The semi-cylindrical tray outer edge plate welded on the outer side of the upper tray prevents the paint from overflowing from the upper tray. After the excess paint is collected, the locking device is opened, and the excess paint is poured into the utensil for unified treatment, which greatly improves the construction efficiency.

[0021] The present invention is described in detail above through specific implementation methods and examples, but these do not constitute limitations of the present invention. Without departing from the principle of the present invention, those skilled in the art may make many modifications and improvements, which should also be considered as the protection scope of the present invention.
