This drilling tool can be different according to the geology condition, use to have the drilling tool that different length lower parts forward crept into the sea whelk, and under same moment of torsion, the reinforcing ability of creeping into reaches the stake end supporting course degree of depth that more is fit for.
Description
Technical field
This utility model relates to a kind of extruding and expanding drilling tool, the helix extruding-enlarging drilling tool that specifically a kind of sea whelk above-below direction is contrary, belongs to construction engineering technical field.
Background technology
It is said that in general, according to the impact on soil layer of the pile forming method of stake, stake can be divided into: Squeezing Soil Pile, part Squeezing Soil Pile and non-Squeezing Soil Pile three major types.Existing filling pile construction major part has continued to use the traditional construction technique of the non-soil compaction such as dry extracting soil, mud off pore-forming.In pore forming process, the stress that soil taking-up can cause soil is discrete, and then causes under the low bearing capacity of stake；Meanwhile, work progress produces substantial amounts of dregs and mud, adds difficulty of construction, cause the problems such as the severe contamination to environment.So, ground circle be devoted to develop always the durable spiral drill of a kind of simple in construction and utilize this drilling tool simple can the spiral extrusion soil filling pile construction method of disposal pore-forming pile.The stake that this type of construction method is formed not only has the incomparable technology of non-Squeezing Soil Pile and cost advantage, also have speed of application fast, without mud, lack construction benefit and the environment-friendly advantages such as dregs, low vibration and low noise.
Patent No. ZL03128265.2 discloses a kind of top to be straight-bar bottom is semi-screw pile and the pile forming method thereof of screw, and semi-screw pile is a kind of variable cross-section part Squeezing Soil Pile, and its underpart is screw pile part.Stake is engaged the collateral resistance that improve Pile side soil to stake with soil body screw, but it still suffers from certain deficiency, rotate forward and sweep spiral shell and carry brill or directly pull out when carrying brill, the slump soil body in stake holes can be ejected ground, it is unearthed more, soil compaction effect is poor, and straight bar part stake week collateral resistance in top is essentially identical with tradition non-Squeezing Soil Pile stake week collateral resistance.
Patent No. ZL200710063983.3 discloses construction method and the bidirectional helix closed extruding expanding drilling tool of a kind of bidirectional helix extruding grouting pile.This bidirectional helix extruding-enlarging cast-in-place pile construction method is Squeezing Soil Pile engineering method, work progress does not produce dregs substantially, and there is soil compaction effect, add the Pile side soil collateral resistance to stake, improve the bearing capacity of stake, but run into relatively hard stratum, used olive-shaped bidirectional helix closed extruding-enlarging aiguille to be difficult to creep into, pile difficulty, it is difficult to arrive suitable supporting course.
Utility model content
Having problems for above-mentioned prior art, this utility model provides a kind of helix extruding-enlarging drilling tool, this helix extruding-enlarging drilling tool structure simple and durable, can according to geological condition, adjust drilling tool core bar diameter and creep into the drilling tool length of sea whelk, using the teaching of the invention it is possible to provide higher drilling ability, the deeper of hole of molding.In addition, not being unearthed in formation of pile, the spiral Squeezing Soil Pile bearing capacity of formation is higher, lower in cost, in hgher efficiency, more environmentally-friendly, and the construction suitable in various soil layers.
This utility model is achieved through the following technical solutions above-mentioned purpose: a kind of helix extruding-enlarging drilling tool, including the hollow drilling tool core bar being made up of top drilling tool core bar and lower drilling tool core bar；Place outside described lower drilling tool core bar integrally formed with creeping into sea whelk, place integrally formed with reverse soil compaction sea whelk outside the drilling tool core bar of described top；Being provided with in described hollow drilling tool core bar cavity and match and through concrete pumping core bar, described hollow drilling tool core bar one end is provided with drill bit, and described drill bit is provided with the valve being connected with described concrete pumping core bar.
Further, creeping into sea whelk described in is that uniform pitch is arranged.
Further, creeping into sea whelk described in is isometrical sea whelk.
Further, the external diameter of described reverse soil compaction sea whelk is for diminish step by step from the bottom to top.
Further, the maximum sea whelk external diameter of described reverse soil compaction sea whelk be not more than described in creep into the external diameter of sea whelk.
Further, described drilling tool core bar is isometrical drilling tool core bar.
Further, sea whelk is crept into described in described reverse soil compaction sea whelk next-door neighbour.
Further, described top drilling tool core bar and lower drilling tool core bar are one-body molded.
The beneficial effects of the utility model are: this drilling tool can be different according to geological conditions, use the drilling tool creeping into sea whelk with different length bottom forward, under same moment of torsion, strengthen drilling ability, reach the bearing course at pile end degree of depth being more suitable for.This helix extruding-enlarging drilling tool forward is used to creep into the degree of depth at the bottom of design stake, not changing direction of rotation, carry in brill simultaneous pumping concrete formation of pile, the stake holes slump soil body is squeezed back hole wall by the reverse soil compaction sea whelk in top, formed at the bottom of stake without sediment loosened soil, the unearthed helix extruding-enlarging stake of whole process；Also can creeping into the degree of depth at the bottom of design stake, reversion carries brill pump concrete and forms screw thread pile body, rotates forward at arrival design reducing place and carries brill pump concrete, forms the top straight-bar pile body of the full soil compaction type semi-screw pile not being unearthed.This utility model drilling tool, simple in construction, it is hardly damaged, drilling ability is strong, and pile-forming speed is fast, and efficiency is high, adapts to the construction under various geological conditions.
