Description
Technical field
The present invention relates to hydraulic engineering field, it is more particularly related to a kind of river course groynes structure and its construction
Method.
Background technology
Groynes is the river regulating structure that or oblique orthogonal with riverbank is stretched into river course, and the end on dam connects with embankment is in
" T " font, the structure and form of construction work of existing groynes still use traditional dam construction method, in order to meet needs, dam
Body is larger along the width of water (flow) direction, and the expenditure of construction made is higher, and construction speed is slower.
The content of the invention
To reduce the expenditure of construction of groynes and improving construction speed, the application first proposed a kind of groynes structure, specifically
Technical scheme it is as follows：
A kind of river course groynes structure, including groynes body, the groynes body include the soil body for being arranged on the side in river course
Interior dam root and the dam body extended from dam root into river course, are filled with stone around dam body；Groynes body include concrete bodies,
With the spaced hollow shell pill of outer rim along concrete bodies, the stake bottom of hollow shell pill is less than the bottom surface of concrete bodies, hollow
Through hole is offered on the pile lining of pile tube, the through hole is in the straight hole shape tilted down from inside to outside；Adjacent hollow shell pill it
Between connection beam is set.
Further, pea gravel concreten is filled with the centre bore of hollow shell pill, pea gravel concreten via through holes are connected to mixed
On the solidifying soil body.Preferably, the stake bottom of hollow shell pill is less than the bottom surface 4-6 rice of concrete bodies.
In the groynes structure of the application, using hollow shell pill as the supporter around groynes body, and in hollow shell pill
Pea gravel concreten is inside poured into a mould, part pea gravel concreten can overflow from the through hole on pile lining, the microlith coagulation that this part is overflowed
Soil can be connected on concrete bodies, made to contact even closer between hollow shell pill and concrete bodies, also enhanced groynes body
Anti-impact force, width of the groynes body along river direction can be efficiently reduced., can on the basis of groynes body width is reduced
The matrix of groynes body is efficiently reduced, reduces the expenditure of construction of groynes.Hollow shell pill is connected as an entirety by linking beam, is protected
The intensity of groynes body is demonstrate,proved.
The application also provides a kind of construction method of above-mentioned groynes structure, specifically comprises the following steps：
(1) according to setting position sinking hollow shell pill, in the lateral surface sinking steel sheet pile of hollow shell pill, steel sheet pile is mutually twisted
Cofferdam is formed, excavation pit and is completed in the range of cofferdam institute corral；
(2) connection beam is installed between adjacent hollow shell pill；
(3) pea gravel concreten is poured into a mould into the centre bore of hollow shell pill, and makes pea gravel concreten from the through hole on pile lining
Extrusion；
(4) concrete is poured into a mould in foundation ditch, while stone is put into concrete, until the designed elevation of groynes body, its
In in the soil body of the side in river course groynes body form dam root, groynes body in river course forms dam body；
(5) steel sheet pile is extracted before concrete solidifies completely；
(6) to surrounding's throwing stone of dam body.
Preferably, the steel sheet pile is U-shaped steel sheet pile.
Preferably, the hollow shell pill is concrete tubular pile.
Preferably, the stake bottom of the steel sheet pile is less than bottom of foundation ditch 3-4 rice.
Using steel sheet pile as cofferdam in this method, the cofferdam formed by steel sheet pile has good water resistance,
In work progress, outside body of water can be effectively prevented from and entered in foundation ditch.At present in the work progress of groynes, still more generally
Using first excavating foundation ditch, then after the inwall installation form of foundation ditch, the cast of concrete is carried out, and in this application, steel sheet pile
The cofferdam formed also has the function that template, eliminates and sets up template in addition, can reduce operating expenses.
