Abstract
The utility model provides the casing device of pore-forming in a kind of building lot, by applying external force to casing, makes impact circular impact soil layer or broken rock, thus drives casing to being lowered into, the stake holes required for simple, efficient formation.The technical scheme adopted is: the casing device of pore-forming in a kind of building lot, casing stack shell is formed with the round steel pipe of certain length and certain diameter, it is characterized in that: casing bottom is with impact cone, the latter half of impacting cone is the cone that diameter is greater than or equal to casing stack shell external diameter, the wedge angle of cone is downward, the first half is the cylinder that diameter is less than casing barrel diameter, the first half of impacting cone is inserted in stack shell from casing bottom, connects in joint welding or casting or is fixed as one with bolt.
Description
Technical field
The utility model relates to field of civil engineering, particularly relates to the drilling construction technology in building lot.
Background technology
In the basement process of building, often run into such situation, under earth's surface there is the larger sandy soils of density, crushed stone soil layer, loess formation, gravel boulder bed in certain depth place, karsts developing area rock stratum and split stone and grow stratum etc., and the hardness of these soil layers is uneven, uneven thickness.This geological conditions causes great difficulty to pile body pore-forming during pile foundation construction, the modes such as vibration sinking tube conventional at present, static pressure or rotary drilling, is substantially all difficult to form stake holes to projected depth.
Summary of the invention
In order to overcome existing hole creating technology for rubble, gravel cobble etc. comparatively hardpan time be difficult to the deficiencies such as pore-forming, work efficiency be very slow, the utility model provides the casing device of pore-forming in a kind of building lot, by applying external force to casing, make impact circular impact soil layer or broken rock, thus drive casing to being lowered into, the stake holes required for simple, efficient formation.
The utility model solves the technical scheme that its technical problem adopts: the casing device of pore-forming in a kind of building lot, casing stack shell is formed with round steel pipe, it is characterized in that: casing bottom is with impact cone, the latter half of impacting cone is the cone that diameter is greater than or equal to casing stack shell external diameter, the wedge angle of cone is downward, the first half is the cylinder that diameter is less than casing barrel diameter, the first half of impacting cone is inserted in stack shell from casing bottom, connects in joint welding or casting or is fixed as one with bolt.
Best, in above-mentioned building lot pore-forming casing device in, impact cone be formed by hard steel solid forging or casting.
Best, in above-mentioned building lot pore-forming casing device in, casing with impact the joint of cone and be welded and fixed with strip steel plate.
Best, in above-mentioned building lot pore-forming casing device in, casing inside is filled with the fillers such as steel cable.
The beneficial effects of the utility model are, first, when applying external force vertically downward to casing, institute's externally applied forces directly acts on foundation soil body by the impact cone of casing, impact cone and produce the impact energy being far more than foundation soil body ultimate bearing capacity, make the soil body around punching week cone or rock stratum produce impact failure, impact cone simultaneously and be connected with casing, thus drive casing integral sinking.Second, be welded and fixed with strip steel plate at casing and the joint impacting cone, its object is except making casing and impacting except the combination more firmly of cone, more significant effect is also embodied in, diameter due to strip steel plate weld is greater than the diameter impacting cone and casing stack shell, therefore several vertical hole slots can be formed when pore-forming on hole wall, the effect one of hole slot is the contact area reducing casing stack shell and the hole wall soil body, reduce frictional force when casing sinks, two is the effects playing air duct, reduce air pressure, casing is enable to sink smoothly or extract, thus significantly improve work efficiency.3rd, casing plays good retaining wall effect in sinking watching, and impact energy also produces compacted effect to surrounding soil or rock stratum, well avoids hole wall collapse, significantly promotes hole quality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the schematic diagrames of the parts of casing device of the present utility model and the embodiment of connection, and Fig. 1 is the sectional drawing before the connection of casing stack shell and impact cone; Fig. 2 is the sectional drawing after the connection of casing and impact cone; Fig. 3 is the sectional drawing after casing and the junction impacting cone are welded and fixed with strip steel plate; Fig. 4 is the top plan view after the connection of casing and impact cone;
In Fig. 1-Fig. 41, casing, 2, taper, 3, strip steel plate.
Detailed description of the invention
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the schematic diagrames of the parts of casing device of the present utility model and the embodiment of connection, the parts of casing device be as shown in Figure 1 in casing 1 and impact cone 2; As shown in Figure 2 in the bottom of casing 1, the cylinder of the first half of impacting cone 2 is inserted into the inside of casing 1, and is welded and fixed in junction; As shown in Figure 3 the junction of casing 1 and impact cone 2 is welded and fixed with strip steel plate 3; Top plan view after the connection of casing 1 and impact cone 2 as shown in Figure 4.
