Background technology
Along with deepening continuously of China's reform and opening-up, China's economic construction stable and rapid development, especially economy development of coastal area has obtained remarkable achievement.As everyone knows, land resources is the important foundation that guarantees economic development, be accompanied by rapid economy development, the construction land growing tension, want the soil to tidal land, become the common recognition of coastal economy developed regions, the bracing of foundation pit of building construction and ground are handled quantity in addition also sharply increases, and requires also more and more higher, but in the enrockment embankment method of making in the ground engineering that is coated with of enclosing in the past, need a large amount of exploitations and use building stones, surrounding enviroment are caused adverse influence, and it is long to exist the settlement stability time, cause the construction period long, sea wall sedimentation and settlement after construction are big, influence the sea wall quality, and a little less than the sea wall impact resistance, poor stability, in addition, these sea wall structure sections are big, and it is big to take oceanic area.
Chinese patent notification number CN2749932Y, a kind of sea wall structure is disclosed, it adopts by conjuncted campshed, reinforcement levee body, plastic draining board, light-duty casting resin, anchor structure and constitutes, the bottom is the levee foundation that vertical plastic draining board is reinforced in the vertical longitudinally conjuncted campshed in both sides, it on it horizontal drainage sand cushion, be the reinforcement levee body on sand mat of subgrade, reinforcement levee body, conjuncted campshed connected, add light-duty casting resin between conjuncted campshed, the reinforcement levee body by anchor structure, crossbeam.This sea wall construction is loaded down with trivial details, and the waste raw material.
Chinese patent notification number CN201506969U, a kind of major diameter embankment tube stake and embankment or dock structure are disclosed, it comprises the solid base of jackstone, levee body and wave wall, adopt the cast-in-place thin-walled sea wall of major diameter tube pilework, for the plain tube sea wall tube pilework of reinforcing cage sea wall tube pilework being installed or reinforcing cage not being installed is arranged; Be provided with the cast-in-place thin-walled sea wall of two to three row's major diameters tube pilework along the dike line; the spacing between the stake of thin-walled sea wall tube adopts the bent structure that can be reduced into 1.5 ~ 3 times of tube stake diameters; the reinforcing cage of installation sea wall tube pilework is arranged for stretching out water surface structure and connecting by the contact beam between the tube stake, the plain tube sea wall tube pilework that reinforcing cage is not installed strengthens structure for being located at submarine structure and adopting many rows to implant the seabed as its vertical embankment.The top of this embankment is to connect whole torque resistant and less stable with the contact beam.
The utility model content
The purpose of this utility model is to provide the stake of a kind of major diameter cast-in-situ concrete tube as the basis, and top connects the sea wall of caisson platform, to solve the torque resistant that exists in the background technology and the problem of less stable.
To achieve these goals, the technical solution of the utility model is: a kind of pile formula caisson sea wall, comprise the caisson platform that is arranged on the weak soil base of coastal engineering seabed, at least two rows that the bottom of described caisson platform is provided with as its carrying implant the bearing peg of the setting in seabeds, the side and face bearing peg that the land side is provided with the setting of implanting the seabed and the horizontal suppressing layer that is positioned at its top of bordering on the sea of described caisson platform.It is dark that bearing peg inserts the seabed, so adopt the support of bearing peg as the caisson platform, the supporting capacity and the stability of sea wall have been improved, and the side and face the land side and also be provided with bearing peg and suppressing layer of bordering on the sea at the caisson platform, further improved the torque resistant ability and the stability of sea wall, the caisson platform that is supported by seabed weak soil base can use as operation platform in addition, places thereon behind the construction machinery according to land job practices construction, reduce the boats and ships operation on the sea, reduced construction cost.
As preferably, described caisson platform is that a plurality of steel concrete casings are spliced, the two sides of the length direction of described caisson platform are the connection end face of steel concrete casing, an end that connects end face is the protrusion connecting portion that outwards protrudes, the other end is inside recessed recessed connecting portion, and described protrusion connecting portion inserts recessed connecting portion and connects.The caisson platform is formed by a plurality of box body splicings, casing flowing water production can be by land in enormous quantities like this, and this casing may float on the water surface and hauls to construction location during construction, has reduced offshore construction, can enhance productivity and safety.
As preferably, be provided with the gusset of crisscross vertical direction in the described casing, described gusset is separated into a plurality of rectangles or square grid with casing, and the grid bottom that described casing borders on the sea side and faces side both sides, land has a hole, and the top of described bearing peg is connected in the hole.With gusset the caisson platform is separated into several grid, the one, can increase the intensity of caisson platform, the 2nd, bordering on the sea side and face in the grid of land side bearing peg is set, this bearing peg forms for the cast-in-situ concrete manufacturing, be separated into that several grid can conveniently be distinguished placing of concrete and unaffected, stake hole in the top of bearing peg and the caisson is built and is integral in addition, makes bearing peg and caisson platform form integral body, and its whole bearing capacity and stability are better.
As preferably, described bearing peg is the stake of large-diameter hollow thin-walled cast-in-situ concrete tube.Bearing peg adopts the large-diameter hollow thin-walled cylinder pile, can save material, reduces cost, because major diameter tube stake prefabricated component inserts the subsea construction difficulty and cost is all higher, pouring forms so adopt at the construction field (site) in addition.
As preferably, the side and face the land side and all have downward wedge angle of bordering on the sea of described bottom half.After casing is sunk to the seabed in shallow sea, because the seabed mostly is the silt soil property, is provided with wedge angle and can allows casing insert in the silt layer, stability is better.
The advantage of the utility model pile formula caisson sea wall is: it is dark that the seabed is inserted in the stake of major diameter tube, support as the caisson platform, the supporting capacity and the stability of sea wall have been improved, and the side and face the land side and also be provided with a tube stake and a suppressing layer of bordering on the sea at the caisson platform, the torque resistant ability and the stability of sea wall have further been improved, the caisson platform that is supported by seabed weak soil base can use as operation platform in addition, construct according to land job practices after placing construction machinery thereon, reduce the boats and ships operation on the sea, reduced construction cost.
