Description

Technical Field

[0002] In water conservancy project construction, cylindrical piers are widely used as core supporting structures in key facilities such as sluice gates, pumping stations, docks, and aqueducts. They bear the weight of water flow, transmit the weight of the superstructure, and protect against environmental erosion. For example, in river regulation projects, cylindrical piers can serve as gate piers to support the opening and closing equipment, ensuring the stability of water flow. In cross-river aqueducts, cylindrical piers must bear the weight of the channel and the water load, while also coping with complex working conditions such as uneven foundation settlement and water erosion.

This leads to problems such as low assembly efficiency, difficult height adjustment, lack of safety protection, and weak connection structures. Therefore, there is an urgent need for a cylindrical pier casting device suitable for water conservancy projects that allows for convenient assembly, free height adjustment, integrated multi-pier connections, and safe and efficient construction, thus meeting the stringent requirements of water conservancy projects for pier column structural reliability and construction economy.

[0039] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0040] Step 1: After the first outer panels 11 of the main structure 1 are relatively fitted together, the docking assembly 14 on one of the first outer panels 11 is used to perform docking and positioning. That is, the waist seat 141 is rotated to move in the adapter groove 44, and the two ends of the waist seat 141 are respectively located in the adapter grooves 44 of the two first outer panels 11. Then, the first bolt 142 is rotated to fix the waist seat 141, and the second bolt 143 located in the top groove 45 is installed to tighten the waist seat 141 again. Then, the four first outer panels 11 are docked in sequence to assemble and form a mold for the cylindrical pier.

[0041] Step 2: When pouring, the delivery port 42 in the groove 41 can be opened, that is, the locking rod 133 in the delivery assembly 13 is moved, the locking rod 133 is rotated from the first locking groove 43 and force is applied downward, one end of the locking rod 133 is lowered and the spring 134 is compressed. After one end of the locking rod 133 is disengaged from the locking claw 132, the inner plate 131 can be disassembled to open the delivery port 42, and the concrete below can be poured or vibrated through the delivery port 42; the inner plate 131 is installed and is limited by the locking claw 132 and embedded in the delivery port 42, and is locked and fixed with the help of the locking rod 133;

[0042] Step 3: When the height of the main structure 1 needs to be increased, the four first outer panels 11 of the main structure 1 are assembled and placed on another main structure 1. That is, the lock seat 12 of the first outer panel 11 is inserted into the seat groove 48 to fit, and the lock seat 12 is fixed in the seat groove 48 by installing the third bolt 144 to assemble and stack to increase the height;

[0043] Step 4: Installing the top platform structure 2 can realize the formation of a platform floor on the top of the assembled main structure 1 for manual standing construction use; that is, according to the actual steel bar spacing requirements, adjust the support arm 22 to move in the adjustment slot 51 of the platform 21, fix the support arm 22 with the fourth bolt 23, adjust the position of the limit seat 24 and the support arm 22, pass the support arm 22 between two vertical steel bars, and then lower it and insert the limit seat 24 into the seat slot 48 for limited placement, and set the platform 21 between the first outer plates 11;

[0044] Furthermore, by inserting the T-shaped end of the lifting arm 25 into the fixing socket 46 and then flipping it over, the upper and lower ends of the T-shaped lifting arm 25 are located at the upper and lower sides of the fixing socket 46, that is, the one end of the lifting arm 25 is located in the fixing slot 47, and the lifting arm 25 can be clamped in the fixing socket 46, so that the lifting arm 25 is perpendicular to the first outer panel 11. Then, the two ends of the corresponding outer pedal 26 are placed in the middle of the lifting arm 25, and the fifth bolt 27 is inserted into the retaining groove 52 of the outer pedal 26 to limit it. An arc-shaped pedal is formed on the outside of the first outer panel 11 for workers to stand on.

[0045] Step 5: Since some bridge piers require two cylindrical piers to be connected and cast to increase the support range and stress strength, three main structures 1 can be assembled to form a mold with an opening. The openings of the two assembled main structures 1 are then placed facing each other and connected with the auxiliary component 3 to form a connection between the two cylindrical piers.

[0046] By providing plate seats 32 at both ends of the docking plate 31, the plate seats 32 are engaged with the first outer plate 11 for docking assembly to achieve communication; if the height is increased, the engaging seats 62 can be inserted into the engaging grooves 61 and tightened with the sixth bolts 33 to assemble and stack;

[0047] If a single cylindrical pier needs to be connected to a rectangular pier body, the three main structures 1 can be assembled and then the docking plate 31 seat and the docking plate 31 can be connected, and a side baffle 34 can be set between the other ends of the docking plate 31. The side baffle 34 is inserted into the fitting groove 61 through the docking claw 35 and fixed by the sixth bolt 33.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
