Description
Technical field
This utility model relates to architectural and civil engineering technical field of construction, particularly relates to a kind of bead string type karst bubble mixing light material pumping filling structure, and it is applicable to punishment construction and the foundation stabilization of karst area beading karst.
Background technology
The stability of the structure foundation of karst region is serious by solution cavity Effect of Fissure, and the existence of karst reduces its foundation bearing capacity, strengthens the sedimentation and deformation of ground.Therefore, in order to avoid or reduce the karst adverse effect to structure foundation, improve its foundation bearing capacity, reduce foundation settlement deformation, thus meet the building requirement to ground, it is necessary to karst region is carried out basement process.
Slip casting method is one of conventional Karst treatment technology.Slip casting method is that the serosity that utilizes pressure to solidify injects in ground space or crack by boring, grout curing or have certain cohesive force or intensity, makes a kind of method that the physical and mechanical property of rock mass improves.Slip casting method in Hydraulic and Hydro-Power Engineering more is referred to as grouting method.It is a kind of very effective construction method that application note prize method processes karst foundation.In general, Grouting engineering teacher controls grouting pressure during slip casting and grouting amount reaches to design requirement, actually grouting design is difficult to again accomplish Exact Design, and serosity moves in Rock And Soil to be affected by many X factors, and people mainly instruct slip casting with theoretical model and experience intuition.
Existing frequently-used injecting paste material mainly has two big classes: chemical classes serosity and cement plasmoid humor.For on injecting paste material, chemical slip casting material degree of turning over is low, concrete castability good, setting time is easy to control, but comprcssive strength is the most much lower after being gelled than cement class injecting paste material, and chemical grout material cost is higher, the corruption candle property of its note frame material, toxicity, meeting produce certain pollution to underground water, so using seldom now.Same a lot of injecting paste material such as macromolecule injecting paste materials, because cost taken by themselves and construction cost are higher and can not be widely used.Another conventional material is exactly cement plasmoid humor, this plasmoid humor low price, and intensity is high, and source is wide.But cement grout gel time is long, in the case of Groundwater In The Karst Area is movable by force, serosity is easily diluted and washes away, and causes note to put up this increase and effect is bad.Therefore, the selection to injecting paste material should consider according to combined factors such as the specific requirement of engineering, geological conditions, size performance, grouting process and costs, selects suitably to starch material, makes engineering reach preferable technical-economic index.
For solving the problems referred to above, research a kind of bead string type karst bubble mixing light material pumping filling structure, karst for bead string type karst area is punished, and can preferably improve rock mass globality, improves Rock And Soil degree of compaction, improve its mechanical property, reduce water penetration, strengthen impermeability, improve ground, bearing capacity of pile foundation, to ensure the quality of engineering, save construction investment cost, reduction of erection time.
