Abstract
The utility model discloses a bag pocket type structure of karst punishment when doing is executed to pile foundation mixes light material, pile foundation, stratum by bag, karst, bubble and constitutes, and the karst distributes in the stratum, and during karst embedding stratum was passed to the pile foundation, the bag bag was passed from the cylinder hole in the bag bag to the pile foundation, and the bag bag meets with the karst, is equipped with the bubble and mixes the light and expect in the bag bag. The bag bag is ring platform shape, and the height is the same with the karst height, and the cylinder hole is left at bag mind -set bottom surface center in the top surface, and bag cross section is the annular, and the cross section is unchangeable to the bottom surface internal diameter from the top surface, and the external diameter is the grow gradually. The technique is reasonable, economic environmental protection, and the effect is showing, has satisfied the demand of filling of the bulky karst foundation pile foundation of karst area construction.
Description
Technical field
This utility model relates to architectural and civil engineering technical field of construction, particularly relates to the bag type paste structure of karst punishment when a kind of pile foundation applies, and it is applicable to punishment construction and the foundation stabilization of karst area large volume 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.Existing slurry injection technique 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.In karst area, often carrying out basement process with pile foundation form through solution cavity, pile foundation lacks power transmission layer in the range of solution cavity, it is therefore desirable to solution cavity is carried out injecting treatment, to provide pile side friction, play the bearing capacity of stake, and for the slip casting of karst, often injecting paste material is full of whole solution cavity cavity, owing to karst volume is excessive, needing substantial amounts of filler to be irrigated, the karst that filler is also possible to along running through runs off in a large number, thus causes waste greatly.Additionally, the note completely of karst fills compared with can providing around pile body and noting filling in the range of frictional force, can not more significantly improve the bearing capacity of pile foundation.Therefore, on the premise of ensureing pile foundation bearing capacity, the most effectively carry out karst filling, thus it is the most necessary for exploring a kind of karst pile foundation construction placement method effective, feasible, that save.
For solving the problems referred to above, study the bag type paste structure of karst punishment when a kind of pile foundation applies, karst for karst area large volume is punished, meet the needs of karst piling Technology, preferably improve rock mass globality, improve its mechanical property, improve ground, bearing capacity of pile foundation, ensure the quality of engineering, save construction investment cost, reduction of erection time, and civil engineering construction, design are the most significant.
Utility model content
The purpose of this utility model is for the karst in the unfavorable foundation that subject building upper load in civil engineering, it is to there are provided the bag type paste structure of karst punishment when a kind of pile foundation applies, rational technology, novel in design, selection is appropriate, and it is convenient to apply, efficient economizing, meet the research needs of karst area large volume karst piling Technology, for karst area civil engineering construction, great significance for design.
For solving the problems referred to above, this utility model employing techniques below measure:
The bag type paste structure of karst punishment when a kind of pile foundation applies, it is made up of pouch, karst, bubble mixing light material, pile foundation, stratum, it is characterized in that: karst is distributed in the earth formation, pile foundation embeds in stratum through karst, pile foundation cylindrical hole from pouch passes pouch, pouch connects with karst, in pouch built with bubble mixing light material.Pouch is annulus platform shape, pouch height and karst heighthIdentical, pouch leaves cylindrical hole from end face center to bottom center, and pouch cross section is annular, and cross section is constant to bottom surface internal diameter from end face, and external diameter becomes larger, pouch cross sectional inner diameter and Pile DiameterΦIdentical, end face external diameterdBigger 0.5 ~ 1.0m than Pile Diameter, end face external diameter passes through calculating formulad=Φ+ (0.5 ~ 1.0m) determines, bottom surface external diameterDAccording to karst heighthBow inclination angle with pouchθ, pass through calculating formulaD= d+2htanθDetermining, pouch inclination angle of bowing is 30 ° ~ 35 °.
Described pouch is that thin-walled elastomeric material is made, and pouch end face leaves injected hole.
In described pouch, filler is bubble mixing light material, bubble mixing light material rapid solidification molding, forms annulus mesa-shaped.
This utility model compared with prior art, has the following advantages and effect:
1) pouch is identical with karst height ensure that packing material contacts with karst top and bottom, pile foundation is made to have preferable power transmission carrier in the range of karst, contact good with casting resin of stake, the offer of pile side friction it is provided and is farthest played, making pile foundation preferably play its bearing capacity；
2) very big due to karst interior void size, it is full of and needs to expend substantial amounts of filler, the filler of molding is limited in around pile foundation by this technique by pouch, it is not necessary to be filled with whole karst, is greatly saved filler while ensureing pile foundation stress；
3) bubble mixing light material has Lightness, and density just corresponds to the 1/5～about 1/8 of portland cement concrete, can alleviate charges Integral Loading.The porous of air bubble mix light-textured soil makes it have low elastic modelling quantity, so that it has good absorption and dispersion to load.
The bag type paste structure of karst punishment when this pile foundation applies, meet the filling demand of karst area large volume karst foundation pile foundation construction, technology is reasonable, economic and environment-friendly, effect is notable, engineering design, construction there is preferable directive function, for karst area civil engineering construction, great significance for design.
