Description
Technical field
The utility model belongs to super soft ground reinforcing technique field, particularly relates to a kind of based on the curing gutter binding structure of using of new hydraulic reclamation super soft ground vacuum preloading shallow-layer.
Background technology
Along with the fast development of China's Coastal Areas economy, land resources growing tension, utilizes and carries out ground stabilization after basin and waterway dredging soil land reclamation again and become the Main Means of alleviating shortage of land resource.Because the dredging soil soil property of hydraulic reclamation mostly recently is mud, its moisture content surpasses 100%, and void ratio is greater than 2.0, and outward appearance is mud scum～stream mud shape, and not yet formation has the soil skeleton structure of intensity, and bearing capacity is almost nil.In the face of super soft ground like this, the main vacuum method that adopts is carried out consolidation process at present.In vacuum method construction technology, setting plastic draining board needs the special-purpose equipment that re-packs, and this equipment belongs to heavy-duty machinery, and weight is about 10-15 ton.How the mire forming at new hydraulic reclamation dredging soil re-packs to construct and becomes the key issue that ground is processed, and mainly comprises following several method at present for this problem:
The one, the equipment modification that re-packs of conventional rail mounted is become to crawler type, operation directly re-pack in the mire that can form at new hydraulically filled sludge.In the method, transform the equipment cost that re-packs higher, the equipment of re-packing after repacking can only fall back and construct in addition, and efficiency of construction is lower, to completing the region re-packing, easily causes disturbance to destroy, and in the process that re-packs, anti-mud situation is serious, and follow-up vacuum preloading construction is had a certain impact.
The 2nd, allow mire that new hydraulic reclamation dredging soil forms first through airing after a while, make its top layer by the fixed formation of natural sediment, there is the crust layer of certain bearing capacity, the more common working cushion layer that meets the equipment construction that re-packs that forms of the flour sand bed course of hydraulic reclamation 80cm～100cm.
The 3rd, on the mire forming at new hydraulic reclamation dredging soil, by artificial plate, carry out the processing of shallow-layer vacuum preloading, make its top layer form the crust layer that one deck has some strength and thickness, and then the common working cushion layer that meets the equipment construction that re-packs that forms of the flour sand of hydraulic reclamation 80cm～100cm.
Method two and method three all need can meet by the certain thickness flour sand bed course of hydraulic reclamation the requirement of the construction working bed course that re-packs, but due to transition exploitation and the use of flour sand in recent years, flour sand resource is more and more in short supply at present, and the construction of hydraulic reclamation flour sand is subject to weather effect larger, usually need long period of time just can complete, this certainly will make construction costs and duration be difficult to guarantee.
In view of above three kinds of construction technologies are to super soft ground stabilization works cost, quality and the Different Effects of duration, we work out a kind of " without sand working cushion layer " vacuum method, can make without hydraulic reclamation flour sand, also can form the working cushion layer that meets follow-up plant equipment construction after shallow layer reinforcement processing.Allow vacuum pre-press reinforcing no longer disturbed in flour sand resource, duration and strengthening quality are all effectively guaranteed, in the middle of design, gutter binding structure is particularly important, it will directly affect drainage effect, existing connected mode is that band drain is ridden on chimney filter and tied up by the mode being wound around, after completing, colligation there is larger gap between its both sides and chimney filter, this gap will have a strong impact on vacuum preloading effect, refer to Fig. 4.
