Abstract
The utility model relates to a drilling bored concrete pile drilling equipment in deep water sand boulder bed riverbed, upper end that protecting a section of thick bamboo outside including and protecting a section of thick bamboo in with, the bottom that a section of thick bamboo was protected in with to the bottom of protecting a section of thick bamboo outward sets up on same horizontal plane protected a section of thick bamboo in, is a bracket height with difference in height between the upper end protected tin outward, be equipped with sealing device outward between the interior outside of protecting a section of thick bamboo and the inboard protected tin, the bottom of protecting a section of thick bamboo outward is equipped with the sword foot. This structural design has rationally solved the drilled pile simply, smoothly and has protected a section of thick bamboo under water and at the pile foundation pore -forming with fill the technological problem that the hole appears scurrying in concrete process easily, ensured pile foundation concrete construction quality under water to ensured that stake footpath size is accurate more than the riverbed, shown and improving the appearance quality who probably exposes the pile foundation concrete of river surface, also any safety of not happening and environmental issue in the work progress.
Description
Technical field
This utility model belongs to hydraulic engineering technical field, is specifically related to cast-in-situ bored pile drilling equipment in a kind of deep water sand pebble layer riverbed.
Background technology
At present, at the sand pebble layer having thickness about 2 ~ 3m, the medium and small particle diameter of Φ 3 ~ 20cm at the bottom of the depth of water about 8 ~ 18m, riverbed, it is middle air slaking tufa stone under sand pebble layer.If directly burying common monolayer steel pile casting underground at permeable sand pebble layer, then under this hydrology and geological state, series of problems will be brought: cement mortar when 1. easily causing mud during pore-forming bottom steel pile casting with perfusion concrete alters hole, causes concrete piles mass defect to drilling pouring pile hole and underwater concrete pouring；2. needing dives under water cuts off monolayer steel pile casting and is embedded in the part in below riverbed, wastes steel pile casting material and adds consuming；3. river is very limpid, is exposed at the water king-pile part in more than riverbed, and its concrete appearance requirement is basically identical with pier stud, and the shape of common monolayer steel pile casting and diameter are difficult to meet this requirement, and waste concrete, and monolayer steel pile casting is 20cm bigger than design stake footpath generally.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art to provide cast-in-situ bored pile drilling equipment in a kind of deep water sand pebble layer riverbed, this reasonable in design is simple, can solve the problem that drilled pile casing under water at pile foundation pore-forming and perfusion concrete process easily there is altering the technical barrier in hole, guarantee pile foundation Underwater Concrete Construction quality, and guarantee that above stake footpath, riverbed size is accurate, significantly improve the presentation quality of the pile foundation concrete being likely to expose river surface.
In order to achieve the above object, this utility model adopts the following technical scheme that
This utility model provides cast-in-situ bored pile drilling equipment in a kind of deep water sand pebble layer riverbed, including outer casing and interior casing, the bottom of outer casing and the bottom of interior casing are arranged in same level, and the difference in height between upper end and the upper end of outer casing of interior casing is a bracket height；It is provided with sealing device between outside and the inner side of outer casing of interior casing；The bottom of described outer casing is provided with cutting shoe.
Gap, bottom between outside and the inner side of outer casing of described interior casing is banded with the water blockoff gunnysack of water-swellable.
The difference of the diameter of described outer casing and interior casing is △ R, 35cm≤△ R≤45cm.
Described interior casing is made up of two symmetrical half of casings, and the junction of two half of casings is equipped with pin hole, and two half of casings link together by ganging up pivot pin.
Described water blockoff gunnysack is fixed on the exterior bottom of interior casing by reinforcing bar press strip.
The steel plate thickness of described outer casing and interior casing is 10 ~ 13mm.
Compared with prior art, the beneficial effect that this utility model obtains:
1. this utility model device is during pore-forming, measure mud balance, calculate according to γ mud h mud=γ water h depth of water formula, determine the discrepancy in elevation between mud face absolute altitude and the outer river face of casing in casing, can ensure that the pressure of the outer river of mud and casing is equal in the casing of casing bottom position, make the mud of position at the bottom of outer casing will not inside and outside alter hole.
2. fix colligation gunnysack, gunnysack water-swellable outside at the bottom of at interior casing, it is possible to blocked in the space between at the bottom of interior casing and at the bottom of outer casing, when making drilled pile underwater concrete pouring, at the water-tight mud of casing bottom position.
3. add casing in a big vertical pivot pin pulling type the same as design stake footpath outside in casing again, so can ensure that the stake footpath irrigated and concrete outward appearance comply fully with requirement, and it is made without imderwater cutting, it is possible to remove on water surface trestle easily and reclaim inside and outside steel pile casting.
4. this utility model device solves drilled pile casing under water smoothly and easily occurs altering the technical barrier in hole at pile foundation pore-forming and perfusion concrete process, ensure that pile foundation Underwater Concrete Construction quality, and ensure that above stake footpath, riverbed size is accurate, significantly improve the presentation quality of the pile foundation concrete being likely to expose river surface, also without any safety and environmental issue occur in work progress.And, by using this engineering method, accomplish that lossless dismounting reclaims whole interior casings and outer casing, and interior casing has not wasted pile foundation concrete as pile foundation template, has saved considerable social resources and construction cost, and has shortened the duration.
