Description

Universal supporting pile shoe structure suitable for underwater rigid ground

Technical Field

The utility model relates to an universal support pile shoe structure suitable for rigidity ground under water.

Background

In various inland rivers and coastal hydraulic construction sites, because most underwater concrete bottom plate planes (adopting laying steel plates under individual conditions) are adopted for hydraulic construction, when engineering ships are adopted for construction, maintenance, repair and maintenance of the hydraulic construction sites, the engineering ships cannot be positioned in a conventional anchoring mode, and are all positioned by positioning piles. When the ship adopts a common positioning pile to contact with the ground of the rigid riverbed, the positioning pile can not effectively eliminate the displacement of the ship caused by stormy waves, so that the normal operation effect of the ship is influenced, and simultaneously, the load of the positioning pile and a fixing mechanism thereof is increased, so that the mechanical damage and even breakage of the fixing mechanism of the positioning pile are caused, and the safety risk is brought to the normal operation of the ship. The main problems are shown in that: 1. the small plane of the contact surface of the pile foot and the concrete is easy to damage; 2. after the pile foot is positioned, the direction is fixed, and the ship can not rotate any more, if the ship needs to turn, the pile needs to be lifted again to move the ship for positioning; 3. without a flushing device, the positioning pile is forced to be lifted in the mud when being lifted; 4. the bearing is complex to connect and disassemble.

SUMMERY OF THE UTILITY MODEL

The utility model discloses its aim at provides an universal support pile shoe structure suitable for rigidity ground under water, when having solved ordinary spud pile and rigidity riverbed ground contact, the spud pile can not eliminate the boats and ships displacement that causes because of the stormy waves effectively, influences the normal operation effect of boats and ships, has increased the spud pile rather than fixed establishment's load simultaneously to cause spud pile fixed establishment's mechanical damage and even fracture, bring the problem of safety risk to the normal operation of boats and ships.

The technical scheme is that the universal supporting pile shoe structure suitable for the underwater rigid ground comprises a pile shoe base plate fixed to the lower side of a positioning pile in a welded mode, a flange plate is fixed to the lower side of the pile shoe base plate, a spherical hinge is fixed to the center of the lower side of the flange plate in a welded mode, the lower end of the spherical hinge is fixed to a hinged support through a pressing sheet, a base is fixed to the lower side of the hinged support, a rubber pad is fixed to the lower side of the base, surrounding plates are fixed to the two ends of the base, a plurality of elbow plates are further fixed to the end face of the upper side of the base in a welded mode, a panel is fixed to the upper ends of the elbow plates, a base pipe joint is further arranged on the end face of the upper side of the base, a support pipe joint is arranged on the end face.

Advantageous effects

Compared with the prior art, the utility model has the following advantages.

1. The underwater concrete bottom plate plane is well protected;

2. the direction of the positioned ship operation can be rotated in any direction, so that the pile lifting and ship moving times are reduced, the operation cost is reduced, the time is shortened, and the efficiency is improved;

3. when the ship is in clear operation, the positioning pile is sunk in the mud and is effectively flushed away by the flushing device so as to easily lift the positioning pile, thereby reducing the loss of the ship;

4. the flange plate of the structure is connected through the hexagonal head bolt, and is simple and convenient to assemble and disassemble.
