Abstract
A method for building a seaport wharf on the soft soil base of a coastal beach comprises the steps as follows: constructing construction cofferdams on the coastal beach; blowing into land in the construction cofferdams and reinforcing the land to form dry land construction condition; building a plurality of support piles in a wharf area, wherein the wharf support pile is a reinforced rib concrete pile, a reinforced rib concrete injecting pile or a steel pipe pile; constructing beams at the top ends of the adjacent wharf support piles, wherein the wharf support piles are connected by the beams to form a frame-shaped integer; building a wharf upper part structure above each beam; arranging a soil baffle wall at the shore connecting side of the wharf, wherein the bottom part of the soil baffle wall is deeper than the port; digging a port pond till at a designed depth; and removing the construction cofferdam while digging the port pond to build the port wharf. Through the method for building a seaport wharf, the construction efficiency is high, the cost is low, and the economic benefit is good.
Description
Technical field
The present invention relates to build the hydraulic structure field of sea port dock.
Background technology
The harbour is national marine door, is the center of shipping and trade, builds the harbour and has very big meaning and economic benefit.
Sea port dock is the main hydraulic structure that the harbour is built, coastal a lot of beach beach is arranged is the weak soil basis in China, on the weak soil basis, build sea port dock,, form very thick mud because the water content on weak soil basis is big, the bearing capacity of mud is very low, the general high-pile beam structural shape that adopts, harbour stake platform supports with large diameter steel pipe pile or prestressing concrete hollow pile, and the degree of depth of pile tube surpasses the weak soil layer, reach the high soil layer of bearing capacity, the weight of sea port dock is supported on the pile tube.The top of pile tube is precast prestressed crossbeam, linking beam, panel and concrete berthing member etc., and it is whole all to adopt the cast-in-situ steel reinforced concrete joint to connect after each member installs.Build and mainly at sea carry out, it is big to be subjected to stormy waves to influence the offshore construction difficulty, builds the sea port dock difficulty much on the weak soil basis, the cost height, and investment is big, and the construction period is long.
Summary of the invention
Technical problem to be solved by this invention is, the method for building sea port dock on a kind of weak soil basis of beach by the sea is provided, and makes the efficiency of construction height, and cost is low, and is good in economic efficiency.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is that the method step of building sea port dock comprises:
One. beach is built to construct and is enclosed low bank between fields by the sea;
Two. hydraulic reclamation becomes the land and carries out the land consolidation process in low bank between fields is enclosed in construction, forms the dry work condition;
Three. build a plurality of harbour supporting piles in the quayside, the harbour supporting pile is reinforced concrete pile, deposited reinforced concrete pile, steel pipe pile;
Four. crossbeam is built on the top at adjacent harbour supporting pile, and crossbeam and harbour supporting pile connect into whole frame construction, construction harbour superstructure on crossbeam;
Five. the bank side that connects at harbour is provided with retaining wall, and it is dark that the degree of depth of retaining wall bottom surpasses digging of harbour;
Six. the excavation basin is dug up construction during the excavation basin and is enclosed low bank between fields to projected depth, builds up port and pier.
Described harbour supporting pile is a steel concrete extruding-enlarging branch tray castinplace pile.
Described retaining wall adopts reinforced concrete sheet pile.
The panel of described harbour superstructure adopts hollowcore slab.
The invention has the beneficial effects as follows: this method is applicable to by the sea builds sea port dock on the beach weak soil basis, invests for a short time, and cost is low, and is good in economic efficiency, construction safety efficient height, and the construction period is short.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 1 is a profile of building sea port dock on the weak soil basis of beach by the sea.Fig. 2 is the piling foundation plan of overlooking of building sea port dock on the weak soil basis of beach by the sea.
The method step of building sea port dock comprises:
One. beach is built to construct and is enclosed low bank between fields 1 by the sea;
Construction is enclosed low bank between fields sea port dock district and sea is separated, and the height that low bank between fields 1 is enclosed in construction should be higher than the average height of seawater, and construction is enclosed low bank between fields with the low silt filling bag construction of cost.
Two. hydraulic reclamation becomes the land and carries out the land consolidation process in low bank between fields is enclosed in construction, forms the dry work condition;
Reclaiming land around sea in low bank between fields is enclosed in construction, make the quayside become land, through consolidation process the quayside is formed again and do ground, dried ground can enter the construction that various land construction machineries carry out supporting pile, crossbeam, harbour superstructure etc., land easy construction, quick, cost is low.
Three. build a plurality of harbour supporting piles 2 in the quayside, harbour supporting pile 2 is one of reinforced concrete pile, deposited reinforced concrete pile, steel pipe pile;
The load of harbour is supported with harbour supporting pile 2, and the structural similarity of this and high-pile beam harbour, harbour supporting pile 2 can bear the load of vertical and horizontal direction.
Four. crossbeam 3 is built on the top at adjacent harbour supporting pile, and crossbeam 3 connects into whole frame construction, construction harbour superstructure 4 on crossbeam with the harbour supporting pile;
Owing to form whole frame construction, so that harbour has high intensity and rigidity, arranged very long application life.
Five. the bank side that connects at harbour is provided with retaining wall 5, and it is dark that the degree of depth of retaining wall 5 bottoms surpasses digging of harbour;
Retaining wall 5 prevents that harbour from connecing the silt leakage at bank place.
Six. the excavation basin is dug up construction during the excavation basin and is enclosed low bank between fields 1 to projected depth, builds up port and pier.
Described harbour supporting pile 2 is steel concrete extruding-enlarging branch tray castinplace piles.The easy construction of castinplace pile, cost is low.Particularly because the chassis has bigger support force greatly.
Described retaining wall 5 adopts reinforced concrete sheet pile.
The panel of described harbour superstructure 4 adopts hollowcore slab.
On the hydraulic reclamation land in the side, land of facing of sea port dock, form the land-based area innerland of sea port dock.The reinforcing soft foundation processing should be carried out in the land-based area innerland, sets plastic draining board.
This method is applicable on the weak soil basis builds sea port dock, invests for a short time, and cost is low, and is good in economic efficiency, construction safety efficient height, and the construction period is short, also is applicable to the construction of enclosing sea dykes, mole simultaneously.
