Description
Technical field
The invention belongs to ship dredging construction technical field, more particularly to a kind of bagged sand rib body construction technique.
Background technology
In ship dredging construction engineering, to ensure the monolithic stability of road structure, bottom first lays elongated high-strength geotechnique
Each one layer of the additional high-strength geotextile of grid, then carries out roadbed filling thereon.Roadbed uses large-scale filling bagged sand, large-scale to fill
Filled using bagged sand in the space filled out between bagged sand and mask.Pavement structure uses hydraulic fill sand, is followed successively by 400g/ ㎡ from the inside to the outside
Geotextiles, 200mm thickness bagged sands.The side-blown back-up sand slope ratio in road sea is 1 on island:30, inner side hydraulic fill sand slope ratio is 1:10；Road surface is certainly
Under it is supreme be followed successively by 500mm thickness mountain skin soil, 200mm thickness graded broken stone, 50mm thickness medium coarse sands bed course, 80mm thickness high-strength concrete connection
Closing piece, both sides of the road are respectively provided with thick 200mm Kerb of concrete.Road surface uses double drainage, the gradient 1%.
In highway engineering construction, large-scale filling bag construction is the key of whole individual works at present, therefore chooses large-scale
Fill bag process and carry out typical construction, construction is built using filling bag heap.Following difficulty in practice of construction be present, (1) takes sand difficult：
Found in construction, the construction area top layer only has 1m Extra-fine sands, and down all silty clays are unfavorable for mud pumping sand；(2)
Transport of materials is difficult：Because placing of material point is distant away from construction area, and sandy ground is unfavorable for transport of materials, therefore is unfavorable for work
Cheng Jindu carries out；(3) activity duration is short, due to during climax beach face large area ponding be unfavorable for mud pumping sand work, only according to
By construction operation during low tide, it is impossible to meet construction speed needs.
For difficult (1), it can expand by being linked up with owner, management and take sand scope mode to solve；For difficulty
(2) it, can be put into by increasing plant equipment, and do good material in advance and have bad luck work, it is ensured that the mode that material is in time
To solve.For difficult (3), then a kind of new construction technology of R ＆ D design is needed to solve, in the prior art and in the absence of conjunction
Suitable above-mentioned technological process.
The content of the invention
The present invention provides a kind of bagged sand rib body construction technique to solve technical problem present in known technology, solves
Problem present in background technology.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：A kind of bagged sand rib body
Construction technology comprises the following steps, and (1) is processed to filling sand pocket, and transports to job site；(2) to filling the setting position of sand pocket
Put and measure positioning；(3) manually sprawled to filling sand pocket；(4) connected under water by delivery hose in the entrance of slush pump
Sand pipette tips are inhaled, connect blast pipe in the outlet of slush pump, blast pipe is connected to the sand inlet for filling sand pocket；(5) in the outlet of water pump
Underwater pipette tips nozzle is connected by delivery hose, the entrance of water pump is connected to clear water puddle by pipeline, and water pump is by the clear of puddle
Water is sucked, and underwater pipette tips nozzle is transported to after pressurization and is sprayed at a high speed, the sand at the bottom is broken up；(6) slush pump passes through underwater
Sand pipette tips, delivery hose and blast pipe is inhaled sand aqueous mixtures are sucked and are delivered to and fill sand pocket.
The advantages and positive effects of the present invention are：It is and existing the invention provides a kind of bagged sand rib body construction technique
The technological process of mud pumping sand sand washing is compared, and the scouring equipment in the technical program is not limited by tidewater, can be significantly using having
The working time is imitated, efficiency of construction is improved, meets construction intensity；The equipment only needs 1 people and mostly mechanically actuated, substantially increases and applies
Work efficiency rate；With manually filling sand facies ratio, avoid fluctuation tide and exchange the program of slush pump sandpit, and reduce the quantity of sandpit,
Scouring equipment can be moved according to section condition of construction.Whole construction technology greatly improves the efficiency of construction, shortens construction
Supply, reduce the cost of construction.
Preferably：Slush pump and water pump are on the surface platform of a floating.
Preferably：It is additionally provided with surface platform to the underwater electric block inhaled sand pipette tips and carry out height regulation.
Preferably：The filling operation that sand pocket is filled in step (6) is more than or equal to 80%.
