Description
Technical field
This utility model belongs to technical field of buildings, is specifically related to a kind of sloped soft-soil foundation ruggedized construction.
Background technology
Nearly having 60% in the area of China is hills and mountain region, and i.e. a lot of Dou Shi slopes, soil, the constructing soil cubic meter of stone on the slope, is one of engineering problem the most universal in civil engineering construction.Sloped soft-soil foundation is a kind of special sloped ground, it is characterized in that ground top layer is the weakest, and bottom foundation surface or soft layer, there is certain cross fall, under embankment load action, soft layer produces the transversely deforming of downwardly directed side while producing compression, concentrate in the middle part of ground different from the deformation of horizontal soft foundation soft layer, the deformation of sloped soft-soil foundation soft layer concentrates near the toe of side, lower section, the shearing strain of side, lower section toe ground can be bigger, it is easier to causes foundation instability.Subgrade embankment on sloped weak ground refers to ground base system soft rock-soil, bearing capacity is relatively low, under filled load effect, ground can produce bigger horizontal distortion, the problem mainly solved when reinforcing sloped soft-soil foundation is in addition to embankment slope stability, and mainly embankment is together with the horizontal distortion of ground and downslide unstability.
In subgrade embankment on sloped weak ground frequently with scheme, such as gravel pile reinforcing structure, composite foundation structure etc., although the stability of Slope Weak Foundation can be improved to a certain extent, but still cannot guarantee that ground does not occur unstability disease.
Summary of the invention
This utility model is for the easy unstability of sloped ground embankment side slope in prior art, under filled load effect, ground easily produces the drawback of bigger horizontal distortion, provide a kind of sloped soft-soil foundation ruggedized construction, the concrete-pile A arranged and concrete-pile B provides firm support force to whole sloped soft-soil foundation ruggedized construction, fixed pressuring plate compresses soft layer, again by reinforcing anchor reinforcing, so that the deformation dispersion of whole sloped soft-soil foundation soft layer, reduce ground deformation, improve stability；The setting of graded broken stone layer makes the bearing capacity of sloped soft-soil foundation increase.
Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of sloped soft-soil foundation ruggedized construction, including the string concrete-pile A being arranged on the weak sloped ground being made up of soft layer and hard basal layer and string concrete-pile B, concrete-pile A and concrete-pile B runs through soft layer and inserts hard basal layer, described concrete-pile A is arranged on bottom slope, concrete-pile B is arranged on top, slope, permutation concrete-pile A is parallel to each other with permutation concrete-pile B, concrete-pile A top and concrete-pile B top are positioned at same level height, the length of concrete-pile B is more than the half of concrete-pile A length；Slope between concrete-pile A and concrete-pile B is provided with fixed pressuring plate, some level pressure holes it are evenly distributed with on fixed pressuring plate, reinforcing anchor it is provided with in level pressure hole, reinforce anchor and run through the soft layer hard basal layer of insertion, reinforce anchor top and be provided with agnail, the setting of agnail makes reinforcing anchor be not easy to come off after inserting hard basal layer, makes structure the most firm, and described reinforcing anchor is that steel material makes；It is provided with spacing walls between described each concrete-pile A, spacing walls cross section is right-angled trapezium, the right angle waist of the spacing walls of ladder structure of right angle is parallel to each other with concrete-pile B towards the right angle waist of concrete-pile B setting and the spacing walls of ladder structure of right angle, spacing walls upper surface flushes with concrete-pile A top, and spacing walls lower end is arranged in hard basal layer；Described concrete-pile A, concrete-pile B and spacing walls are arranged over tamping layer, tamp and are provided with packed layer between layer and fixed pressuring plate.The setting of spacing walls, firmly can be limited in graded broken stone layer in sloped ground, it is to avoid graded broken stone fault position, and spacing walls is arranged to ladder structure of right angle, and structure can be made more stable.
Described packed layer includes some steel wires parallel to each other, is equipped with graded broken stone layer between steel wire, and the surrounding of steel wire described in adjacent two-layer is connected by vertical steel wire.
The aperture of steel wire is less than the particle diameter of graded broken stone.Prevent graded broken stone from passing in the hole of steel wire, thus avoid steel wire not reach the effect of due restriction graded broken stone.
Described steel wire is at least two-layer.
The cross section in described level pressure hole is inverted "convex" shape structure, and described reinforcing anchor tail end is provided with pressure strip.Time in level pressure hole on reinforcing anchor insertion fixed pressuring plate, reinforce the level pressure hole top half of the pressure strip press-in inverted "convex" shape structure of anchor tail end, fixed pressuring plate is tightly secured on the soft layer on slope, fixed pressuring plate is played good fixed effect by the hard basal layer reinforcing anchor insertion sloped ground, so that the stability raising that sloped ground is overall.The pressure strip reinforcing anchor tail end flushes with level pressure hole top edge, and the pressure strip reducing reinforcing anchor tail end is damaged by graded broken stone layer.
Compared with prior art, this utility model has the advantages that concrete-pile A that this utility model arranges and concrete-pile B provides firm support force to whole sloped soft-soil foundation ruggedized construction, fixed pressuring plate compresses soft layer, again by reinforcing anchor reinforcing, so that the deformation dispersion of whole sloped soft-soil foundation soft layer, reduce shearing strain, thus reduce ground deformation, improve stability；The setting of graded broken stone layer makes the bearing capacity of sloped soft-soil foundation increase；The setting of the spacing walls of ladder structure of right angle too increases the stability of graded broken stone layer, and graded broken stone layer uses the setting that steel wire surrounds, and again increases stability.
In sum, this utility model can make the bearing capacity of sloped soft-soil foundation increase, and reduces sloped soft-soil foundation deformation, significantly increases the stability of sloped soft-soil foundation.
