Abstract
The invention discloses a kind of reclaiming land around sea to combine layering drainage method for processing foundation, including serous fluid of dredger fill layer, blast layer, sand bedding, whirl spraying bar, virtual drainage channel, virtual drainage direction.Construction procedure is divided into：To wait fill out 1~1.5m of hydraulic fill sand thickness in place；Mud of the hydraulic reclamation with design height again；After standing for 2~March, surface layer bleeding is drained, prepares to vacuumize；Geotextiles are laid with, thickness 30~50cm sand bedding course is repaved, covers sealing film, vacuumize；Sealing film is opened, layering drainage processing is carried out.The present invention combines layering drainage method for processing foundation advantage to be that vertical drainage body penetrates through blast layer+serous fluid of dredger fill layer+three layers of sand bedding foundation structure, shortens foundation soil drainage distance, forms two-sided discharge structure；Layering drainage cuts foundation soil to form multiple horizontal direction drainage channels again, greatly speeds up foundation drainage rate, shortens the duration, reduces project cost.
Description
Technical field
The invention belongs to reclaiming land around sea technical fields, and in particular to a kind of reclaiming land around sea combination layering drainage basement process
Method.
Background technique
Reclaiming land around sea is the important means that coastal area solves construction land.Traditional reclaiming land around sea is generallyd use to banket skill
Art forms land-based area, and the barged-in fill soil property in hydraulic reclamation region is poor, and water content is high, and foundation bearing capacity is low, and sedimentation is not yet stable, therefore needs
Basement process is carried out to barged-in fill, commonly eating filled up ground processing method includes heavy-tamping method and vacuum method, heavy-tamping method
Of fine quality for clay and muddy ground first to select vacuum method suitable for sandy soil, conventional vacuum method is spread using surface layer
If layer of sand and plastic foil are vacuumized, water discharge time is relatively long, and basement process efficiency is lower.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of reclaiming land around sea combination layering drainage method for processing foundation, adds
The fast foundation drainage time, increase basement process efficiency.
Technical solution is as follows：A kind of reclaiming land around sea combines layering drainage method for processing foundation, mainly includes：Serous fluid of dredger fill
Layer, blast layer, sand bedding, vacuum chimney filter, vacuum supervisor, woven cloth, sealing film, sealing ditch, vacuum pump, air compressor machine, whirl spraying are set
Standby vertical drainage body, whirl spraying bar, virtual drainage channel, virtual drainage direction.
Including following construction procedure：
(1) to wait fill out 1~1.5m of hydraulic fill sand thickness in place；
(2) mud of the hydraulic reclamation with design height again；
(3) after standing for 2~March, surface layer bleeding is drained, prepares to vacuumize；
(4) geotextiles are laid with, thickness 30~50cm sand bedding course is repaved, covers sealing film, vacuumize.
(5) sealing film is opened, layering drainage processing is carried out.
It is described to vacuumize as traditional vacuum method, including, sand bedding, vacuum chimney filter, vacuum supervisor, braiding
Cloth seals film, seals ditch, and vacuum pump waits equipment and materials.
The layering drainage is, provides high pressure gas using air compressor machine, is transmitted to whirl spraying equipment, and whirl spraying equipment is to soil
Whirl spraying bar is squeezed into vivo, pressure-air is rotated from whirl spraying bar bottom level to ejection with whirl spraying bar, and soil layer is made to cut to be formed
Horizontal direction drainage channel (virtual), then whirl spraying bar position is changed, whirl spraying is repeated, multiple horizontal channels (virtual) is formed.
Beneficial effects of the present invention are：Vertical drainage body penetrates through blast layer+serous fluid of dredger fill layer+three layers of sand bedding ground base junction
Structure shortens foundation soil drainage distance, forms two-sided discharge structure；Layering drainage again foundation soil is cut to be formed it is more
A horizontal direction drainage channel, greatly speeds up foundation drainage rate, shortens the duration, reduce project cost.

Specific embodiment
A specific embodiment of the invention is described with reference to the accompanying drawings and embodiments：
Embodiment 1
As shown in Figure 1, a kind of reclaiming land around sea of the invention combines layering drainage method for processing foundation, it mainly include hydraulic reclamation
Mud layer 1, blast layer 2, sand bedding 3, vacuum chimney filter 4, vacuum supervisor 5, woven cloth 6, sealing film 7, sealing ditch 8, vacuum pump 9,
Air compressor machine 10, whirl spraying equipment 11, vertical drainage body 12, whirl spraying bar 13, virtual drainage channel 14, virtual drainage direction 15.Construction
Steps are as follows：
(1) to wait fill out 1~1.5m of hydraulic fill sand thickness in place, as shown in Figure 2；
(2) again hydraulic reclamation with design height mud, as shown in Figure 2；
(3) after standing for 2~March, surface layer bleeding is drained, prepares to vacuumize；
(4) geotextiles are laid with, thickness 30~50cm sand bedding course is repaved, covers sealing film, vacuumize.
(5) sealing film is opened, layering drainage processing is carried out, the layering drainage is to be provided using air compressor machine 10
High pressure gas, is transmitted to whirl spraying equipment 11, and whirl spraying equipment 11 squeezes into whirl spraying bar 13 into the soil body, and pressure-air is from 13 bottom of whirl spraying bar
Portion's horizontal direction sprays, and rotates with whirl spraying bar, makes soil layer cut to form horizontal direction drainage channel (virtual), then change whirl spraying bar
