Abstract
The utility model aims at providing a bearing pile, which can greatly reduce the decrease of bearing force caused by soil liquefaction. The bearing pile is characterized in that the inner portion of the bearing pile is provided with a drainage channel which is communicated with the outer circumference of the pile, in order to realize the exhaust of water in foundation soil, thereby reducing the weakening of the bearing force of the bearing pile. And the drainage channel comprises horizontal holes (1) and vertical holes (2).
Description
Technical field
The utility model relates to field of civil engineering, particularly relates to a kind of bearing peg as the basis.
Background technology
In the past, bearing peg is often adopted on the basis of civil engineering, for this bearing peg, in the relatively poor occasion of many geological conditionss, its essence is passed through frictional force, support to upper building is provided, but, running into liquefaction soil, such as, during the loosening sand layer, often because the vibration that the dynamic load on tops such as earthquake, highway, railroad bridge produces stake, the end resistance of the frictional force of pile vibrosinking, the equipment that dynamic load is bigger, the factory building perisporium of above-mentioned stake because of liquefaction of soil mass makes or stake bottom soil reduces, and the bearing capacity of stake is reduced.In addition, because liquefaction of soil mass also can cause the reduction of liquefaction soil to the horizontal resistance of stake.
The disclosure of an invention scheme
The purpose of this utility model is to provide a kind of bearing peg, and it can lower the reduction of the bearing capacity that causes because of liquefaction of soil mass greatly.
Above-mentioned purpose of the present utility model is to realize by following bearing peg, in this bearing peg,, has the drainage channel of the periphery wall of the stake of being communicated in the inside of this bearing peg, so that the discharge of the water in the realization foundation soil body reduces the weakening to the bearing capacity of bearing peg.
According to such scheme, owing to drainage channel is set in the inside of stake, its periphery wall with stake is communicated with, so the stake perisporium water on every side that liquefaction is caused is discharged to this permeable partial interior, and discharges by drainage channel, when weakening because of pile driving construction so greatly (such as, high frequency liquid shakes formula hammering stake and the vibration that produces) liquefaction cause to pile lining frictional force, horizontal force, the harmful effect of stake end power, thereby can keep stable pile capacity, or improve pile capacity.
In above-mentioned bearing peg, above-mentioned drainage channel is included in the lateral aperture of all wall openings of stake.
According to such scheme, be opened on a lateral aperture of side perisporium owing to be provided with, so can prevent a liquefaction of the foundation soil body of side perisporium.
In above-mentioned bearing peg, above-mentioned lateral aperture has a plurality of, also comprises the vertical row water hole in addition, and it is communicated with above-mentioned lateral aperture.
According to such scheme,, in the bigger long scope of stake, prevent the liquefaction of foundation soil body more effectively because the vertical row water hole of a plurality of lateral apertures and these a plurality of lateral apertures of connection is set.
In above-mentioned bearing peg,, above-mentioned drainage channel is set in the stake bottom.
According to such scheme, owing to, above-mentioned drainage channel is set in the stake bottom, thus water can be discharged fast, thus excess hydrostatic pressure reduced, reduce end resistance, the quick sinking of convenient stake in sinking to process.
In above-mentioned bearing peg, above-mentioned bearing peg is that above-mentioned stake is precast reinforced concrete pile, precast prestressed reinforced concrete pile, steel pipe pile, steel tube concrete pile.
In above-mentioned bearing peg, above-mentioned drainage channel is vertical along stake, from the stake top, extends to a bottom.
According to such scheme, because longitudinally connecting from top to bottom, drainage channel is provided with, so can in the long scope of whole stake, prevent liquefaction to frictional force, the harmful effect that horizontal bearing capacity causes effectively.
In above-mentioned bearing peg, be provided with the stopple that to meet water-solubleization in the above-mentioned drainage channel, to avoid in the sinking process by the soil obstruction.
According to such scheme, because above-mentioned stopple so can avoid the obstruction of drainage channel, can be realized effective draining.
In above-mentioned bearing peg, above-mentioned drainage channel is communicated with pump.
According to such scheme, owing to above-mentioned drainage channel is communicated with pump, so can discharge ground water effectively apace.
Brief description of drawings
Fig. 1 is the elevation as the bearing peg of an embodiment of the present utility model;
Fig. 2 is the transverse sectional view as the bearing peg of an embodiment of the present utility model.
The embodiment that is used to carry out an invention
As illustrated in fig. 1 and 2, precast reinforced concrete pile 1 as an embodiment of the present utility model is pile tube, it comprises a plurality of lateral apertures 1 as drainage channel that are arranged in tube wall, comprise the vertical hole 2 that is arranged in tube wall in addition, this vertical hole 2 is communicated with above-mentioned a plurality of lateral apertures 1, above-mentioned vertical hole 2 up/down perforations, and a plurality of lateral aperture 1 is opened on the periphery wall of pile tube 1, is embedded with reinforcing bar 4 in the concrete of tube wall.Because a plurality of lateral apertures 1 are set, its periphery wall with stake is communicated with, like this can be in the work progress of stake, and the water of the liquefaction of soil mass in the stake side perisporium foundation soil body on every side that causes because of the stake of high frequency liquid vibration beating is effectively discharged.In addition, vertically a bottom is led in hole 2, thereby can discharge the water of a bottom, in the piling construction process, can reduce to squeeze into when beating the degree of depth, because of excess hydrostatic pressure forms bigger penetrating resistance like this.Stake vertically, from top to bottom, have liquefiable powder soil horizon, sand layer and gravel soil layer.In liquefiable powder soil horizon, sand layer and gravel soil layer, because of outer thereby generation liquefaction, the water that is produced can enter in the stake from lateral aperture 1 in the liquefiable sand layer.In addition, stake bottom surrounding soil can take place in sand layer and gravel soil layer produce excess hydrostatic pressure, because perpendicular person hole 2 extends to a bottom, so can reduce this excess hydrostatic pressure.In addition, be provided with the stopple that to meet water-solubleization in the above-mentioned drainage channel, to avoid in the sinking process by the soil obstruction, though not shown in the drawings about this point.
Claims (8)
