Description
Technical field
The utility model belongs to civil engineering work technical field, particularly relates to a kind of pre-buried floral tube grouting and reinforcing device on soft foundation.
Background technology
Saturated soft soil is distributed widely in China coast various places, and inland rivers marshland endemic area, they have, and water content is high, void ratio is high, compressibilty is high, and permeability is low, shear strength is low, low bearing capacity, " three high three low two powers " engineering properties that rheological characteristic is strong, thixotropy is strong.Soft foundation is the main ground formed by saturated soft soil, and because its compressibilty is high, greatly, settlement stability lasts length for settlement of foundation and inhomogeneous deformation.Therefore, soft clay area is natural ground, building in composite foundation or pile foundation all easily produce differential settlement, causes the inclination of building, in addition, build the factory building on large-area soft ground and local-style dwelling houses, because adopt pile foundation under its agent structure base for post, large area terrace then majority adopts cushion, pressure (rammer) real method, composite foundation after the method process such as Deep Mixing Method, due to the differential settlement between basis (cushion cap) and terrace, foundation and terrace is caused to throw off, form the pot shape depression on ground, so that terrace breaks, pipeline is impaired, wall, beam, destroying appears in the superstructures such as post, driving waits production equipment to use difficulty, not only affect its outward appearance and normal function, even cause time serious and cannot use.
In order to carry out rectification and reinforcement of building improvement to above-mentioned soft foundation building disease, mostly adopt the methods such as anchor jacked pile, root pile (mini pile), high-pressure rotary jet grouting pile, cement mixing method, fracture grouting or Combination of Methods to carry out rectification and reinforcement of building in the past.But the common weak point of these methods is costly, construction controls by existing building steric requirements, adds difficulty of construction, affects construction speed; And construction period has a strong impact on normal work and life in building, cause the pollution to environment and destruction simultaneously.
Summary of the invention
The purpose of this utility model is to solve building rectification and reinforcement of building method engineering time length on existing soft foundation, costly, by existing building environment limiting, construction period affects the weak point of the normal use of former building, and provides a kind of pre-buried floral tube grouting and reinforcing device on soft foundation of simple and feasible.
The purpose of this utility model has been come by following technical solution, comprise grouting tube, valve, described grouting tube is embedded under basis, be connected and fixed with joint between grouting tube, arranged outside slip casting tube head in basis, this slip casting tube head communicates with grouting tube, and slip casting tube head is provided with valve.
As preferably, in described grouting tube, be provided with plug, the valve on each slip casting tube head and form an independently slip casting subsystem with adjacent plug.
As preferably, described grouting tube is steel pipe or U-PVC pipe, grouting tube offers injected hole, is wrapped with rubber sleeve.
The beneficial effects of the utility model are: whole pre-buried grouting tube system architecture is simple, quick construction, easy to use, cost is not high, compared with other rectification and reinforcement of building methods in the past, save a large amount of pore-forming, Finish time and expense, and not by building space constraint, do not affect it during grouting and reinforcing normally to use, environmentally safe.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in accompanying drawing 1 to 3, the utility model comprises grouting tube 2, valve 6, described grouting tube 2 is embedded under basis 1, this basis 1 is single footing or strip foundation or pile foundation support table, be connected and fixed with joint 5 between grouting tube 2, according to scale and the load of building, in basis 1, outside arranges slip casting tube head 7 at a certain distance, this slip casting tube head 7 communicates with grouting tube 2, slip casting tube head 7 is provided with valve 6; Be provided with plug 8 in described grouting tube 2, the valve 6 on each slip casting tube head 7 and form an independently slip casting subsystem with adjacent plug 8, slurries flow range controls by it.After building are completed, when the uneven sedimentation of ground and excessive sedimentation and deformation need to carry out rectification and reinforcement of building, the valve 6 of corresponding site can be opened, grouting and reinforcing is carried out by slip casting tube head 7, slurries are washed the rubber sleeve 4 wrapped up in outside grouting tube 2 open and are entered through injected hole 3 in the soil body waiting to reinforce position, because there is preset plug 8 to control, slurries can only treat reinforcing ranged flow what specify, thus reach the object to reinforcing location grouting and reinforcing.
Described grouting tube 2 is steel pipe or U-PVC pipe, and its material, according to building load and deadweight size, selects steel pipe or the U-PVC pipe of different-diameter; Grouting tube 2 offers injected hole 3, be wrapped with rubber sleeve 4, in case injected hole 3 is blocked by concrete during foundation construction.
Below by embodiment, and by reference to the accompanying drawings, technical solutions of the utility model are described in further detail.
Embodiment 1: the pre-buried floral tube grouting reinforcement technique of soft foundation of the present embodiment, as shown in Figure 1, 2, 3, when foundation construction, pre-plugged grouting tube 2 under basis 1, grouting tube 2 offers outside injected hole 3 and be enclosed with rubber sleeve 4, connect with joint 5 between grouting tube 2, according to architectural scale and load, arranged outside valve 6 and slip casting tube head 7 in basis 1.When building occurs that excessive sedimentation and differential settlement need to carry out rectification and reinforcement of building to ground, open the valve 6 must reinforcing position, namely grouting and reinforcing can be carried out by slip casting tube head 7, because there is default plug 8 to control, after slurries wash rubber sleeve 4 open by injected hole 3, the ranged flow that needs reinforcement that can only specifying, thus reach the object to needs slip casting location ground rectification and reinforcement of building.
Embodiment 2: as shown in Figure 4, building adopt pile foundation, and grade adopts banketing of compacting, and when foundation construction, pre-plugged grouting tube system in the terrace outside basis 1, its ingredient is identical with embodiment 1.Because differential settlement causes main part and terrace to throw off after building come into operation, just by the grouting tube 2 of pre-plugged in terrace, slip casting is carried out to it, thus prevent the relative settlement of terrace and main part, avoid the destruction of terrace, pipeline, road.
The utility model is not limited to above-mentioned embodiment; no matter do any change on its shape or material are formed; every employing structure design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
