Abstract
The utility model relates to a novel pile tip for soft clay foundation treatment, which belongs to a construction facility of detritus (dinas) and plain concrete piles of a composite foundation and comprises a pile pipe. The utility model is characterized in that a round of limit ledge is arranged on the inner wall of a pile pipe with a distance of 150mm away from the end part of a sunk pipe, a pin shaft is arranged under the limit ledge, the pin shaft is provided with two semicircular steel plates, the two semicircular steel plates are hinged together through the pin shaft, the semicircular steel plates are provided with steel wire ropes, and the steel wire ropes penetrate through the wall of the pile pipe. The pile tip can be applied for various stratums, a valve can be flexibly opened no matter for saturated silt or soft clay, and the phenomenon of pipe clamping can not appear.
Description
Technical field
The utility model belongs to the construction installation of immersed tube gravel (sandstone), plain concrete pile, is specifically related to a kind of soft clay foundation and handles novel stake point.
Background technology
Fig. 1 is the structure chart of existing stake point.It constitutes tapered flapper-type structure for being provided with 4 flap valves in the end of steel pipe.It in work progress, if when running into the weak soil layer and since foundation soil by the disturbance of stake point after, structural deterioration becomes soft moulding ~ stream and moulds state; The outer lateral earth pressure increase of stake point causes flap valve not open fully, thereby causes broken pile, necking down folder mud.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned technology exists, to provide a kind of soft clay foundation to handle novel stake point.
The feature of the utility model stake point is that the stake inside pipe wall of distance stake tube end 150 mm is provided with all place-limited edges, the below of place-limited edge is provided with bearing pin, bearing pin is provided with two blocks of semicircle steel plates (being the dual-active lobe), two blocks of semicircle steel plates are hingedly connected together by bearing pin, semicircle steel plate is provided with wire rope, steel wire penetrating stake tube wall.When the stake point buries, to utilize wire rope to mention two blocks of semicircle type steel plates to place-limited edge place and seal a pipe place, earth can not enter in the pipe when making a pipe sink in the soil.Feed intake in pipe after stake pipe bottom reaches desired depth, wire rope unclamps automatically when carrying pipe, and the dual-active lobe is opened automatically.
It is wide that the utility model is used the stratum, no matter is saturated powder soil horizon or runs into soft clay stratum, because two pages split steel plate in the stake pipe, so avoid soil that it is formed side pressure, flap valve can both be opened flexibly, and broken pile, necking down folder mud phenomenon can not take place.
Description of drawings
Fig. 1 is the axial sectional view of existing stake point.
Fig. 2 is the axial sectional view of the utility model embodiment.
Among the figure, 1, stake pipe, 2, semicircle steel plate, 3, bearing pin, 4, place-limited edge, 5, wire rope, 6, semicircle steel plate.
The specific embodiment
Embodiment: shown in Figure 2, present embodiment comprises stake pipe 1, the stake inside pipe wall that it is characterized in that distance stake pipe 1 end, 150 mm is provided with all place-limited edges 4, the below of place-limited edge 4 is provided with a bearing pin 3, bearing pin 3 is provided with two blocks of semicircle steel plates 2,6, two blocks of semicircle steel plates 2,6 are hingedly connected together by bearing pin 3, and semicircle steel plate 2,6 is provided with wire rope 5, and wire rope 5 passes a tube wall and stretches outside tube wall.
The flap valve of present embodiment is two blocks of semicircle steel plates 2,6.
