Abstract
The invention discloses a pile inserting type ship external pile flushing method, which belongs to the technical field of ocean engineering.
Description
Technical Field
The invention relates to the technical field of ocean engineering, in particular to a pile inserting type ship external pile punching method.
Background
With the development of ships and ocean engineering, more and more ships use the pile inserting system. The pile inserting system heavily depends on the pile punching system to punch the pile to destroy the adsorption force of the boot bottom when the pile is pulled out. If the pile punching system cannot work, the adsorption force of the boot bottom cannot be damaged, pile pulling is very difficult, and pile legs have to be cut off in many cases to solve related problems.
Disclosure of Invention
The invention aims to solve the technical problem of providing a pile inserting type ship external pile punching method, which can smoothly realize external pile punching at the boot bottom so as to assist pile pulling operation under the condition of not cutting pile legs.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: a pile inserting type ship external pile punching method comprises the following steps:
(1) after the first working ship is in place, jacking equipment arranged on the first working ship carries out jacking operation according to the position of the pile shoe, a jacking pipe controls the jacking pipe to push out a mud surface upwards after passing through the bottom of the pile shoe, and an air compressor is arranged on the first working ship;
(2) connecting the end part of the jacking pipe to an air compressor, inflating the jacking pipe through the air compressor, and connecting a thin steel wire to the end part of the jacking pipe by a diver through a second working ship on the other side of the pile inserting ship;
(3) starting recovery equipment to recover a jacking pipe, and drawing the thin steel wire back to the first working ship by the jacking pipe;
(4) drawing and replacing steel wires by the two workboats, connecting thick steel wires at the end parts of the thin steel wires, driving the thick steel wires by the thin steel wires, and tightening the thick steel wires to enable the thick steel wires to be tightly attached to the boot bottom of the pile shoe after the thick steel wires with proper sizes are replaced;
(5) after the thick steel wires are close to the boot bottom of the pile boot, the ship positions of the two workboards are moved, and the thick steel wires are pulled so that the thick steel wires move back and forth along the boot bottom for a certain distance in the direction vertical to the thick steel wires, and the non-tight adsorption area is enlarged;
(6) an inflation pipe is pulled to the bottom of the pile shoe along a steel wire, and after the pipe head is in place, a large-flow air compressor is connected for pile punching until the adsorption force of the pile shoe is completely destroyed and loosened;
(7) if the pile punching range of a single inflatable pipe is limited, pile punching is carried out on a plurality of inflatable pipes which are scattered in the installation position in the previous step;
(8) and (5) performing pile pulling operation after the pile is flushed for a certain time.
By adopting the technical scheme of the invention, the following beneficial effects can be obtained:
the pile inserting type ship external pile punching method adopts non-excavation equipment to wrap a steel wire through the bottom of a pile shoe, damages the soil structure at the bottom of the pile shoe by pulling the steel wire to destroy the adsorption force of the pile shoe, introduces an inflation tube into the bottom of the pile shoe through the steel wire to further destroy the adsorption force of the bottom of the pile shoe by external pile punching at the bottom of the pile shoe, and can penetrate a plurality of steel wires if the area of the bottom of the pile shoe is too large and air bubbles on the water surface are too concentrated, and simultaneously punch piles by installing a plurality of inflation tubes to increase the pile punching effect.

As shown in fig. 1, 2 and 3, the pile inserting type ship external pile punching method comprises the following steps:
(1) after the working ship 1 is in place, jacking equipment arranged on the working ship 1 carries out jacking operation according to the position of a pile shoe, a jacking pipe 3 controls the jacking pipe 3 to push out a mud surface upwards after passing through a pile shoe sole 4, and an air compressor is arranged on the working ship 1;
(2) connecting the end part of the top pipe 3 to an air compressor, inflating the top pipe 3 through the air compressor, and connecting a thin steel wire to the end part of the top pipe by a diver through a second working ship 2 on the other side of the pile inserting ship;
(3) starting recovery equipment to recover the jacking pipe 3, and drawing the thin steel wire back to the working ship I1 by the jacking pipe 3;
(4) drawing and replacing steel wires by the two workboats, connecting thick steel wires at the end parts of the thin steel wires, driving the thick steel wires by the thin steel wires, and tightening the thick steel wires to enable the thick steel wires to be tightly attached to the boot bottom 4 of the pile boot after the thick steel wires with proper sizes are replaced;
(5) after the thick steel wires are close to the boot bottom 4 of the pile boot, the ship positions of the two workboards are moved, and the thick steel wires are pulled so that the thick steel wires move back and forth along the boot bottom for a certain distance in the direction vertical to the thick steel wires, and the non-tight adsorption area is enlarged;
(6) an inflation pipe is pulled to the bottom of the pile shoe along a steel wire, and after the pipe head is in place, a large-flow air compressor is connected for pile punching until the adsorption force of the pile shoe is completely destroyed and loosened;
(7) if the pile punching range of a single inflatable pipe is limited, pile punching is carried out on a plurality of inflatable pipes which are scattered in the installation position in the previous step;
(8) and (5) performing pile pulling operation after the pile is flushed for a certain time.
The pile inserting type ship external pile punching method adopts non-excavation equipment to enable a steel wire bag to pass through a pile shoe sole 4, the soil structure at the bottom of a pile shoe is damaged by pulling the steel wire so as to destroy the adsorption force of the pile shoe sole, an inflation tube is introduced into the pile shoe sole 4 through the steel wire so as to further destroy the adsorption force of the pile shoe sole 4, if the area of the pile shoe sole 4 is too large, bubbles on the water surface are too concentrated, a plurality of steel wires can be additionally passed, and a plurality of inflation tubes are installed to simultaneously punch piles so as to increase the pile punching effect.
