The dry packet sandbag construction method in reef sand cofferdam.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that
A kind of dry packet sandbag construction method based on hydraulic reclamation reef sand cofferdam, characterized by the following steps: (1), apply
Work measurement and setting-out, the processing of geotextile bag body, go out axis and set steel on the face Yuan Jiao 1 before constructing using measuring instrument measuring
Pipe is identified, and is suitably encrypted in arc section and dog-ear section；Geotextiles are cut by geotextile bag body computational length
Several, then the protection geotextiles cut are sewed into code requirement according to geotextiles along its length, it sews up into needed for cloth bag
Width；
(2), foundation trench excavates: hydraulic reclamation was taken at the land stage and first blew back wall early period, was directly filled out backfill reef sand blast by dredger
To cofferdam construction region, foundation trench is dug on the spot with excavator, foundation trench width determines that grooving length is bigger by the dry packet sandbag width of bottom
In cofferdam construction length, foundation trench excavates the nearest other side of reef sand in foundation trench two sides, use when backfilling；
It after land-based area takes on a certain scale, takes and first encloses after-blow, soil construction is first returned with dump truck by hydraulic reclamation region
It fills out to form work surface, backfill section width is determined according to builder's road and weir bottom width degree；
(3), geotextile is laid with bag body, and the bottom of the dry packet sandbag body of bottom is fixed using the steel pipe set in advance；
(4), cofferdam bag body is constructed, the dry packet sandbag filling of bottom: surveying and locating first, using steel pipe the dry packet sandbag of bottom
The bottom of body is fixed, and then in excavator back-up sand to the dry packet sandbag body of bottom, bottom is done with portable sewing machine after sand is full
Packet sandbag body is sewed it up, and is finally washed by water closely knit；When thickness is insufficient or local eminence, artificial stop-off high-pressure water pipe should be flattened or used in time
Water-filling leveling；
The dry packet sandbag filling in middle layer: the dry packet sandbag in middle layer is laid with above the dry packet sandbag body of bottom；Equally, excavator is utilized
In back-up sand to the dry packet sandbag body in middle layer, the dry packet sandbag body in middle layer is sewed it up with portable sewing machine after sand is full, is finally washed by water close
It is real；It, should artificial stop-off leveling in time or with the leveling of high-pressure water pipe water-filling when thickness is insufficient or local eminence；
The dry packet sandbag filling in upper layer: the dry packet sandbag in upper layer is laid with above the dry packet sandbag body in middle layer；Equally, it is filled out using excavator
In sand to the dry packet sandbag body in upper layer, the dry packet sandbag body in upper layer is sewed it up with portable sewing machine after sand is full, is finally washed by water closely knit；
It, should artificial stop-off leveling in time or with the leveling of high-pressure water pipe water-filling when thickness is insufficient or local eminence；
(5), after the completion of the body of weir, protection geotextiles is laid with and are laid with sun-proof geotechnique in time after the completion of the bath of top layer sand pocket is closely knit
Cloth wraps up entire sand pocket cofferdam.
The advantages and positive effects of the present invention are: the present invention efficiently solve it is higher in material shortage, transportation cost
Deng the problem of regional hydraulic reclamation cofferdam construction, can gather materials on the spot, it is easy for construction, it is loose to packing material Particle size requirements, it can quick shape
At cofferdam, the advantages that greatly reducing construction cost, accelerate construction speed.The method is sufficiently demonstrated by engineering construction example
Its exploitativeness and economical.
