Abstract
Description
The present invention relates to an underwater installation method of a pier using a work line for omitting a temporary water film installation process. More particularly, the present invention relates to a method of installing a pier in an underwater rocky ground with a base space, After removing the soft ground in the drained basement, it is placed on the rock so that the top is exposed to the water. After connecting to the pile, the foundation space and the entrance space are filled with reinforced concrete, The process of finishing the remaining construction in the structure is related to the underwater installation method of the bridge pier using the work line propelled by the barge with various construction equipments.
In order to construct bridges, tidal power plants or water buildings in river or tidal tidal and high-wave waters with fast flow rates, we have secured a work area much larger than the pier foundation area as a provisional tundish.
However, depending on the depth of the construction area and the amount of water passing through, the depth of the soft ground, and the height of the structure, it is necessary to secure the area for loading the terrazzo, the residual soil, the equipment working space, the access road, And, the farther away from the land, the exponential increase in the cost and time for the temporary dam construction and the risk of flooding due to the collapse can not be ruled out.
In particular, straits or streams where the tidal currents flow into the tidal flats should be constructed several times depending on the number of passes and the progress of the construction, and countermeasures should be taken against the increase in the number of tidal flats or floods.
The Sihwa tidal power plant, which built 400 m of tidal power plant, was constructed with a water tide of 2km or so along with the sea tide that was already completed on the road. However, due to the collapse of the embankment, It was stopped. In addition to this, it proves that the reclaimed soil was enough to make artificial islands of several thousand pyeong.
When a wind turbine is installed on the sea or an analogue pier is pierced, a method of piling a pile or applying a vacuum to a pile of a pile is used in a thick underwater floor, but in a thin layer of soft pile, a hard rock is drilled Structures such as tidal power plants can not replace the foundation with only such files.
Therefore, there is a need for a method of connecting the upper end to the upper plate or installing a water structure so that the upper end of the bridge can be exposed to the water surface at the designed position without the provision of a temporary waterwall. This is because the remaining construction can be finished in the above-mentioned roof or the water structure.
It is to fix the pile on the rock to the support so that the pier made on the ground is exposed to the water and fix the bottom to the rock.
In order to accurately fix the bridge to the rock, two or three piles should be correctly pushed in place on one pier and there should be little clearance between the bridge and the pier. The pier must be light enough to fit in the pile, And a drainage tunnel should not be formed beneath the pier when draining to work, or buoyancy should not be generated.
When an underwater structure is installed on a waterway formed by a pier like a tidal power plant, an arc-shaped water gate is installed on both sides. It is easy to reinforce the skeleton so that it can withstand the water pressure greater than the flat water gate, and underwater structures such as aberration bases and underwater beams can extend out of the waterway.
In order for such a process to be carried out in water, the ground support base for constructing and supplying structures such as piers, barges with various construction equipments, and material carriers are carried out by division and cooperation, and when the worker is working in the basic space Ventilation is required to discharge toxic gases from the machine or spewed from underground.
This method omits the construction of temporary trenches as well as the temporary bridge construction, the trenching area is limited to the foundation section of the pier, so the amount of residual soil is small, and the backfilling or dismantling process is omitted or reduced, The normal flow of water is maintained and environmental changes are minimized and the process is not interrupted unless a disaster such as a typhoon or an earthquake occurs.
The object of the present invention is to develop an underwater installation method of a pier using a work line so that the pier is fixed to the submarine rock bed and the upper part is exposed to the water surface without finishing a provisional waterwall or temporary bridge construction work.
In order to accomplish the above object, the underwater installation method of a pier using a work line is a ground support base having a loading dock or a foundation formed of a base space wall having a wedge-type bit at the lower end, A center pillar formed integrally with the base space wall and having a plurality of central pile spaces vertically penetrating therethrough and an entrance space; a center pile insertable into the central pile space; Substructure fabrication process;
Wherein the bridge pier is sandwiched between a plurality of the center piles fixed to the rock, a gap formed between the wedge-shaped bit and the sea bed is filled with the gravel charged into the foundation space, and waterproofed from the upper part of the bridge, exposed to the water surface, Piers installed and waterproofed to prevent flooding and flooding after draining with curtains;
A pier fixing step of removing the soft ground and loose rock so that the wedge-shaped bit reaches the rock, or a plurality of piles are laid on the floor, and the remaining space of the base space, the access space and the center pile space is filled with reinforced concrete;
An underwater structure installation step in which an arc-shaped water gate is installed on both sides of the water channel formed by the pier with the waterproof curtains disassembled and the water curtain is adhered to the outside of the arc-shaped water gate and the seabed and drained;
And a remaining process to be completed in the pier or the augmented structure assembled in the underwater structure;
All processes are carried out by drill machines, pile installation equipment, crane and dredging equipment, concrete pouring equipment, generators and ventilators, multiple barge lines and material carriers with lifting, maneuvering and anchoring functions. .
The bridge pier may be divided into a plurality of steps according to the depth of water and the exposure height or weight of the installation area and connected to the center file inserted in the center file space.
Wherein the waterproof curtain has a floor material whose inner periphery coincides with the cross section of the pier and whose outer periphery is cut into an ellipse or a circular shape, An inner skin extending to the railing provided on the bridge pier, and an outer cover having a buoy and a steel block attached together at the upper end of which the lower end is sealed with the outer periphery of the floor and is reinforced with a sling or a wire. And the soil is inserted into the ∪ -type bag formed around the pier so that the bottom portion can be closely attached to the seabed so that the cutting portion is seamably detachable in a plurality of pieces according to the external shape of the pier.
The dismantling of the waterproof curtain is characterized in that the buoy is removed and the soil is removed from the ∪-type pouch whose envelope sinks to the weight of the steel bar, and the piece of cut-off is loosened and separated one by one.
In the present invention, since the temporary water filming process is omitted and all the processes from the manufacture and installation of the bridge pillar structure to the remaining construction are promoted through the division of labor or collaboration, the construction period is shortened as long as the weather condition is allowed and the risk of collapse, There is almost no process, and it can be recycled to arc-shaped water curtains and waterproof curtains as well as work lines and carrier ships, which greatly reduces the construction cost and maintains normal tidal flow and river flow during the construction period.
