Abstract
The invention relates to a concrete large cylinder structure. The concrete large cylinder structure comprises a concrete large cylinder structure body and is characterized in that a plurality of high-pressure flushing jet pipelines are uniformly distributed in the circumferential cylinder wall of the concrete large cylinder structure body, and the high-pressure flushing jet pipelines are connected with an external high-pressure flushing device. A method of flushing sink comprises the steps of prefabricating the concrete large cylinder structure; hoisting the concrete large cylinder structure to a sink position; externally connecting the high-pressure flushing device, thus jetting high-pressure water flow from jet holes communicated with the high-pressure flushing jet pipelines to cut soil below the concrete large cylinder structure until the concrete large cylinder structure sinks to the target height; and filling the high-pressure flushing jet pipelines with cement paste. The concrete large cylinder structure adopts the flushing sink, thereby avoiding damage to the cylinder structure when a vibratory hammer sinks; and only flushing equipment is needed during construction, and large construction ships are not needed, so that the construction period can be greatly shortened and the construction cost can be reduced.
Description
Technical field
The invention belongs to water conservancy project gravity-type structure, what more particularly, to a kind of concrete Between Cylinder and its bath were sunk applies
Work method.
Background technology

Banket or increase the buried depth of pile foundation, lead to construction costs expensive.Concrete Between Cylinder is to grow up in recent years and pole
A kind of new hydro-structure pattern of tool application prospect.It, similar to bottomless, no partition wall cylinder caisson structure, is suitable for soft
The complex conditions such as soil base and severe sea condition, have that structure is simple, stress condition is good, the construction period is short, low cost, good endurance
The advantages of, can be used for the hydraulic structures such as preventing the bank from flood, trraning pole, harbour and ocean platform.
Concrete Between Cylinder sinking construction is typically sunk using vibration or hammering, but vibration and hammering sink to easily making to mix
Solidifying soil large cylinder barrel cracking, thus affect the durability of structure.When sinking stratum is harder, vibration and hammering sinking are difficult,
Exist and be difficult to concrete Between Cylinder sinking to the problem of target absolute altitude, structural stability is constituted a threat to.
Patent documentation 2115364 discloses a kind of concrete large cylinder stake, and cylinder bottom is lance tooth side, and tooth side end face is three
Angular groove, circumferentially has axial discharge pipeline, feed pipe and air supply pipe in barrel, has one than tooth side top slightly below cylinder
High annular boss, preset one annular gas pipe communicating with air supply pipe in it, can upwards jet and make on cylinder surrounding form gas
Barrier film is to reduce sinking side-friction force.During sinking, feed pipe is sprayed water so as to interior soil is constantly rushed to tooth side triangular open space
Rise and discharge upwardly through discharge pipeline along triangular groove, lead to cylinder constantly to sink to designated depth.The defect of this patent is big
Cylinder pile water jet quantity is few, aperture is relatively large, and water flow pressure is limited, limited to soil layer cutting power；And lance tooth side
Precasting process is complicated, prefabricated after the completion of, large cylinder can not be touched with ground.
Patent documentation 1963042 discloses a kind of hydraulic sheeting and its using method, including reinforced concrete peg board and its interior hang down
The water pipe excessively directly installed, the water operation pipe being connected with mistake water pipe that bottom is laterally installed, the slideway that side is installed, opposite side
The slide plate installed, the lifting suspension ring that top is installed and embedded reserved steel bar, also include in described reinforced concrete peg board, slideway, cunning
The vertical water proof road of the both sides setting of plate.The defect of this patent is that reinforced concrete sheet pile structure dimension is limited, and how length is in 2m
Within, more than width within 0.5m, restricted application.
Urgently develop one kind in the construction of the hydraulic structures such as preventing the bank from flood, trraning pole, harbour and ocean platform to have
Structure is simple, stress condition is good, the construction period is short, the concrete Between Cylinder of low cost, good endurance.
Content of the invention
It is an object of the invention to overcoming the shortcomings of above-mentioned technology, and provide a kind of concrete Between Cylinder and its bath
The construction method sunk, only need to use flushing device during construction, without using Large Construction ship, can be greatly saved construction week
Phase.
The present invention for achieving the above object, employs the following technical solutions: a kind of concrete Between Cylinder, including concrete
Between Cylinder body, is characterized in that: is evenly equipped with some high pressure in the circumference barrel of described concrete Between Cylinder body
Bath injection line, described high-pressure flush injection line is connected with external high-pressure water-flushing device.
Described concrete Between Cylinder body bottom portion is connected with annular steel base, and described annular steel base is provided with
Spray-hole that is corresponding with high-pressure flush injection line and connecting.
Described high-pressure flush injection line is made using thin-wall steel tube.
Described concrete Between Cylinder body cross-section shape is rounded or polygon.
The construction method that a kind of concrete Between Cylinder bath is sunk, concrete technology step is as follows:
(1) land precast concrete Between Cylinder body, is burying high-pressure flush playpipe near barrel inner side
Road, is prefabricated into concrete Between Cylinder；
(2) pass through square refuting and concrete Between Cylinder is transported to job site, crane gear lifting concrete large cylinder knot
Structure is to subsidence position, and slow sinking is to mud face, and under Gravitative Loads, concrete Between Cylinder sinks stable；
(3) the high-pressure flush injection line of concrete Between Cylinder body is connected with external high-pressure water-flushing device, opens
Dynamic high-pressure water-flushing device, makes High-Pressure Water spray cutting concrete large cylinder from the spray-hole that high-pressure flush injection line connects
The soil body below structure；
(4) High-Pressure Water pressure size is regulated and controled according to soil property situation, adjust concrete Between Cylinder fall rate, until
Sinking is to target absolute altitude；
(5) remove high-pressure water-flushing device, cement grouting in high-pressure flush injection line, by high-pressure flush injection line bag
It is rolled in concrete, the bath completing concrete Between Cylinder is sunk.
Beneficial effect: compared with prior art, the concrete large cylinder of the present invention is sunk using bath, it is to avoid vibration hammer
Damage when sinking to, cylindrical structure being caused, only need to use flushing device during construction, without using Large Construction ship, can be very big
Save construction period, reduce operating expenses.Concrete Between Cylinder has that structure is simple, stress condition is good, the construction period is short,
The advantages of low cost, good endurance, can be widely used for the hydraulic structures such as preventing the bank from flood, trraning pole, harbour and ocean platform.
