Abstract
The utility model relates to a composite pile member for a composite foundation. The technical problem to be solved is to provide a composite pile member which can simultaneously solve problems, such as the insufficient liquefaction resistance, the insufficient bearing capacity, the unevenness, the float resistance, etc. of the soil of a foundation. The utility model has the technical proposal that the member is composed of a reinforced concrete bottom board, a concrete cushion layer, a broken stone cushion layer, vibrosinking pile and a root pile, wherein, the root pile and the vibrosinking pile which is arranged on the periphery of the root pile in a parallel way are perpendicular to the reinforced concrete bottom board, and the concrete cushion layer and the broken stone cushion layer are orderly arranged under the reinforced concrete bottom board. Furthermore, the root pile extends into the reinforced concrete bottom board, and a main rib of the pile is bent into an inclination angle and connected with the reinforced concrete bottom board. Besides, the vibrosinking pile is arranged below the broken stone cushion layer. The utility model can be used for tap water plants, sewage treatment plants, fuel electric plants, oil tanks and underground garages.
Description
Technical field
The utility model relates to a kind of composite pile member that is used for composite foundation.Be applicable to that water works, Wastewater Treatment Plant, steam power station, oil tank, underground garage etc. need to solve the ground processing of the anti-liquefaction of foundation soil, bearing capacity deficiency, heterogeneity and anti-floating problem.
Background technology
Existing composite foundation by strengthen in the ground body direction be divided into level to, vertically strengthen bluk recombination ground two classes.The vertical bluk recombination ground that strengthens can be divided into again: discrete material pile, flexible pile and rigid pile composite foundation three classes.Solve at present the not enough and anti-liquefaction problem of bearing capacity of foundation soil often by immersed tube or shake and dash broken stone pile or the solution of sand pile composite foundation that two kinds of construction technologies form, the anti-floating of building is usually by the method for concrete counterweight, pile foundation and native anchor.But solve bearing capacity of foundation soil deficiency, anti-liquefaction problem and building anti-floating problem simultaneously, at present manyly carry out ground with vibrations tube-sinking cast-in-situ pile or compaction pile and handle, but the method only be applicable to artificial earth fill, mucky soil, generally cohesive soil and when immersed tube, do not produce liquefaction silt and in close powder fine sand soil.Produce during to immersed tube liquefaction silt and in close powder fine sand soil foundation engineering be difficult to ensure the quality of products.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiency that exists in the prior art and a kind of composite pile member that is used for composite foundation is provided, this mechanical system interaction energy becomes row coordination, acting in conjunction, can solve problems such as the anti-liquefaction of foundation soil, bearing capacity deficiency, heterogeneity and anti-floating simultaneously, make the building safe handling.
The technical scheme that the utility model adopted is: the composite pile member that is used for composite foundation, form by reinforced concrete floor, concrete cushion, hardcore bed, vibrosinking pile, root pile, its design feature be root pile and on every side with it the vibrosinking pile of parallel distribution perpendicular to reinforced concrete floor, be followed successively by concrete cushion under the reinforced concrete floor, hardcore bed, the main muscle that root pile stretches into reinforced concrete floor and stake curves the inclination angle and is attached thereto, and vibrosinking pile is below hardcore bed.
The pile ring muscle of the utility model uniform determining deviation on root pile.
Described root pile diameter is thin than vibrosinking pile, and length is long than vibrosinking pile.
Described root pile perpendicular to reinforced concrete floor, is distributed with vibrosinking pile in the centre on every side, and vibrosinking pile and hardcore bed are perpendicular.
The beneficial effects of the utility model are: this member has utilized the mechanical system principle that can become capable coordination, acting in conjunction, temper toughness with gentleness, and flexible vibrosinking pile solves the anti-liquefaction of foundation soil, bearing capacity deficiency and uneven subsidence by shaking towards closely knit; And the root pile of the certain rigidity of tool vertically has stronger frictional force and anti-pulling capacity, can strengthen the vertical active force of foundation soil, solves the floating holder problem of building.Structurally, reinforced concrete floor is connected with root pile, can give full play to the anti-pulling capacity of root pile, the effect that concrete and hardcore bed have buffering and coordinate.Make reinforced concrete floor, concrete cushion, hardcore bed, vibrosinking pile, root pile and inter-pile soil form an organic whole, bear the not same-action under the different operating modes of building jointly.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
The utility model is made up of reinforced concrete floor 1, concrete cushion 2, hardcore bed 3, vibrosinking pile 4, root pile 5.Reinforced concrete floor 1 is positioned at top, base plate as the pond, the following of concrete floor is concrete cushion 2 and hardcore bed 3 successively, thin and long root pile 5 vertically is positioned at concrete floor 1, root pile passes hardcore bed 3 and concrete cushion 2 extend in the reinforced concrete floor 1 always, root pile is furnished with the pile ring muscle 7 of some main muscle 6 and certain intervals, the top of the main muscle 6 of stake curves the oblique angle, be attached thereto effectively after putting in concrete floor 1, its effect is that groundwater table rises or the maintenance operating mode when occurring, the anti-pulling capacity of performance root pile 5 makes ground have the anti-floating ability, is unlikely to produce the building come-up.Under the building nominal situation, form the carrying of composite pile system by reinforced concrete floor 1, concrete cushion 2, hardcore bed 3, vibrosinking pile 4, root pile 5.
