Description
Technical field
The present invention relates to a kind of concrete pile that keeps off soil, bank protection, space enclosing structure, particularly a kind of π shape concrete pile.
Background technology
Conventionally because highrise building spacing distance is little, the excavation of foundation ditch cannot accomplish to take to put the way of slope excavation sometimes, for the safety of the stable and surrounding buildings of foundation ditch, need to carry out retaining support to foundation ditch; In the construction of dredging waterway, high-grade highway construction, bridge, Rail Highway grade separation and culvert, also need to build retaining support structure in addition.
At present for the method for pattern foundation pit supporting structure, mainly contain the methods such as bored pile, diaphragm wall, these method costs are high, man-hour is long, are mainly used in the Extra-Deep Foundation Pit that soil body extruding force is large; But for the shallow foundation pit foundation plinth of two-layer basement, financial cost is higher; Also some adopts steel sheet pile as pattern foundation pit supporting structure material, although can use continuously overall cost or higher on current domestic this class foundation ditch basis.
Diaphragm wall, this structure is suitable for full water soft stratum, saturated silt soil strata etc.; In this type of soil layer, diaphragm wall can intercept underground water effectively, but its cost is very high, is applicable to municipal key project, and is not suitable for the engineerings such as general highrise building.
Bored pile is to adopt campshed piling wall to keep off soil and waterproof, realize going along with sb. to guard him of foundation ditch, it is not suitable for deep layer base pit engineering, quality control is unstable, and soil erosion is easily caused in gap between stake, particularly in high water level bury matter area, need take suitable working measure to solve dash problem according to engineering specifications, and between stake and stake,, mainly by stake apical cap beam with enclose wingceltis and cause entirety, thereby relative globality is poor.
SMW(Soil Mixing Wall) engineering method stake is the stiffness material that inserts H shaped steel or other kinds in cement mixing method, comes the bending resistance of refinforced cement soil agitation pile, shear resistance; Although this kind of method is faster than construction of diaphragm wall speed, take up an area less, the relative fender post of its process cost is higher, and steel using amount is large, and construction is complicated.
Steel sheet pile is the underground enclosed structure stake of one of commonly using, although its bearing capacity is high, the restriction of stake footpath is little, be not suitable for deep-foundation pit engineering, and its engineering quantity is large, and keeping off native load performance does not have diaphragm wall superior, and cost is not low yet.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of π shape concrete pile that a kind of cost is low, have high bending resistance, high shear behavior.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of π shape concrete pile, described π shape concrete pile is made by concrete, described π shape concrete pile comprises that a cross section is the pile body of π shape, described pile body is comprised of with the supporting leg that is positioned at pile body bottom and be connected with crossbeam the crossbeam that is positioned at pile body top, the both sides of described crossbeam have had the first connecting portion and second connecting portion of connection function, described the first connecting portion and described the second connecting portion shape lean and leave gap between the fitting face coordinating, and in described gap, concrete perfusion is starched, filled watertight rubber bar or encapsulant is set.
In one embodiment of the invention, the pvc pipe that described encapsulant is hollow, the tube wall of described pvc pipe is provided with aperture, concrete perfusion slurry in described pvc pipe, and the concrete grout of perfusion is by gap described in the filling small hole distributing on pvc pipe wall.
In one embodiment of the invention, described the first connecting portion middle part has a groove, and these groove both sides are symmetrical first shoulders that protrude; Described the second connecting portion middle part has a projection corresponding with above-mentioned groove, and these projection both sides are second shoulders of symmetrical sinking; The first shoulder of described the first connecting portion and the second shoulder of described the second connecting portion are mutually corresponding; The projection at described the second connecting portion middle part is less than the groove at described the first connecting portion middle part with respect to the degree of depth of its first shoulder with respect to the height of its second shoulder.
In another embodiment of the present invention, described the first connecting portion and described the second connecting portion have shape lean coordinate wedge configuration.
In yet another embodiment of the present invention, the bottom of described supporting leg is provided with bending section, described bending section be provided with the left branch leg syndeton identical with the first connecting portion structure and with the identical right supporting leg syndeton of the second connecting portion structure.
By technique scheme, the invention has the beneficial effects as follows:
The present invention is that cross section is the concrete pile of π shape, has high bending resistance, high shear behavior on its structure stress, also has certain weight-bearing function; In addition, the connecting portion on both sides is equivalent to a buckling plate, in the middle of joint splicing is rear, can leave gap, and some paste materials or other link materials can be inserted in this gap, guarantee stagnant water effect and bonding strength, can be used as permanent supporting and protection structure and use.
