Problems solved by technology

If you want to build bridge piers on a wide strait, when the water depth is tens of meters or hundreds of meters, it is very difficult to build bridge piers with this construction method because the pressure and buoyancy of the water on the side walls of the steel cofferdam are very large. Unable to construct

Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0043] As shown in Figure 1-6, a diving pile driver includes an esophagus (1), a submersible (2), a water breaking chamber (4), four hydraulic legs (5), and several steel immersed tubes (9) , two pressure devices (10), several submersible drilling rigs (11), and several fasteners. Its submersible (2) is made up of material allocation bin (3), control room (6), water storage bin (7), pressure bin (8). The perforations (13) of several steel immersed tubes (9) are arranged on the bottom plate of the pressure chamber (8), and four guides (12) are arranged on the hole wall of each perforation (13). The steel immersed tube (9) is inserted in the perforation (13) on the bottom plate of the pressure chamber (8) and in the perforation (14) on the bottom plate of the water cut-off chamber (4), and the submersible drilling rig (11) is installed on the bottom of th...

Abstract

A submersible pile driver for driving the steel tube-concrete pile and building foundation underwater by several hundreds of meters in water depth is disclosed. A case with holes and no cover for said foundation is made and then linked to the pile driver via screws. The submersible drilling machine, hydraulic pile driver and concrete pouring machine for sunk pipes are combined into a whole. Its technological steps include sinking said assembly in water, drilling holes on said case, inserting and welding steel pipes, installing and welding joist, pouring concrete is steel pipes, and disconnecting the case.

Description

technical field [0001] The invention relates to a device capable of constructing foundations under water, which can continuously complete the construction of steel pipe concrete piles and foundation caps at a depth of several hundred meters. Specifically, it is a diving pile driver. Background technique [0002] At present, the main method of building bridge piers in water is to use steel cofferdams as enclosures, and the construction of piles and foundations is carried out under the enclosure of steel cofferdams without water. The construction method is to sink the steel cofferdam to the bottom elevation of the foundation cap, impact the soil in the steel cofferdam with a high-pressure water gun to make it into mud, pump out the mud and pour the bottom concrete in water to make the bottom concrete and The steel cofferdam forms a relatively airtight barrel. Then, the water is pumped out and the piles and foundations are constructed. During construction, there is a water l...
