Abstract
The utility model relates to a rotary type protective sleeve double drilling apparatus for construction. The round steel protective sleeve is provided with a spiral auger concentric with the steel protective sleeve; the upper parts of the steel protective sleeve and the spiral auger are respectively provided with the driving head of the steel protective sleeve and the driving head of the spiral auger; the steel protective sleeve and a driving head connector concentric with the spiral auger are arranged between the driving head of the steel protective sleeve and the driving head of the spiral auger. The utility model has the advantages of simple structure, and convenient installation, and can improve the pile base pouring quality and the carrying capacity.
Description
The utility model relates to a kind of auger device for building.
At present, in China's building pile foundation construction, usually under groundwater table geological conditions high and not pore-forming, construct, general equipment and the method construction of adopting common auger boring slip casing by pressure retaining wall, the inside spin bored pile construction equipment of the grandson inventor Xinhe River invention of in 1996 Zhengzhou City, China Henan Province is to carry with the helix transporting device that auger stem and the sleeve pipe that is set in the auger stem outside are formed to bore soil, yet said apparatus is failed to solve outer tube and how to be overcome the difficult problem (promptly this device can't be constructed and be grown stake and large aperture stake) that boring subsoil resistance creeps into spiral.
It is a kind of simple in structure that the purpose of this utility model is to provide, and can carry out the two boring devices of rotary casing of poured pile base, the long stake of construction and large aperture stake under underground quicksand, the inferior geological conditions in weak soil ground.
In order to achieve the above object, the technical solution adopted in the utility model is made up of auger stem, it is characterized in that in the circular steel casing, being provided with the auger stem concentric with the steel casing, steel casing, auger stem upper end are fitted with steel casing driving head and auger stem driving head respectively, are provided with between steel casing driving head and the auger stem driving head and steel casing, the concentric driving head connector of auger stem.
The utility model has the advantages that:
Simple in structure, be convenient to install, can under underground quicksand, the inferior geological conditions in weak soil ground, carry out the construction equipment of poured pile base, the long stake of construction and large aperture foundation, effectively improve poured pile base quality and supporting capacity, guarantee construction engineering quality, reduce integrated cost simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model adopts the two boring devices of a kind of rotary casing, it is to be provided with the auger stem 4 concentric with steel casing 3 in circular steel casing 3, steel casing 3, auger stem 4 upper ends are fitted with steel casing driving head 2 and auger stem driving head 1 respectively, are provided with the driving head connector 5 concentric with steel casing 3, auger stem 4 between steel casing driving head 2 and the auger stem driving head 1.
The two boring devices of the rotary casing of the utility model are that the steel casing that is rotated by suit outside auger stem is that the steel casing is set outside the auger stem, they drive (rotation) steel casing simultaneously by driving head separately respectively and auger stem rotates, along with the moving casting of the brill of auger stem is crept into and the rotation of steel casing overcomes surrounding soil friction and steel casing bottom soil body resistance along with creeping in the soil body, when holing to desired depth, auger stem is mentioned, reinforcing cage is positioned in the steel casing, the full concrete of perfusion, vibrator is vibrated on steel casing top, the steel casing rotates simultaneously, then, by hoist engine the steel casing is lifted rise.Adopt the concrete compaction of above-mentioned construction pile foundation perfusion, effectively improve poured pile base quality and supporting capacity.
The utility model can bore the stake hole of 400-1000mm diameter.Described steel casing can adopt general steel plate, presses the bore diameter processing and fabricating.
