Abstract
The invention discloses a construction method of method of occlusive piles of a water-containing pebble bed and a saturated sandstone stratum. The construction method comprises the following steps that (1), A-type piles 1 are conducted, the piles are plain concrete piles, holes are formed through a rotary drilling rig, in the hole forming process of the rotary drilling rig, only part of sleeve pipes are installed on hole openings, after the holes are formed, the perpendicular degrees of the pile holes in the hole forming process are tested through a full-automatic pile hole clinometer, and after the perpendicular degrees are tested to be qualified, low-grade concrete is poured into the holes; and (2), B-type piles 2 are constructed, the piles are rebar concrete piles, pile bodies of the two adjacent A-type piles 1 on the two sides are cut through a drilling rig bit of the rotary drilling rig, holes are formed through rotary excavating, after the holes are formed, the perpendicular degrees of the pile holes in the hole forming process are tested through the full-automatic pile hole clinometer, after the perpendicular degrees are qualified, rebar cages are placed in the holes, and finally, concrete is poured into the holes. The construction period is shortened, cost is saved, and production efficiency is improved.
Description
Technical field
The present invention relates to construction method of interlocking pile technical field, more particularly to aqueous boulder bed and saturation sandstone ground
Layer construction method of interlocking pile.
Background technology
As the propulsion of Process of Urbanization Construction process, urban architecture are more and more intensive, job site is less and less,
Limited by space, the measure of sloping timbering is no longer applicable.Especially the excavation of foundation pit of aquifer water-bearing stratum, cheats outer
Large-area precipitation not only results in the waste of groundwater resources, also results in the sinking of surrounding building, influence
Using for building is safe.Therefore the measure of the interior precipitation of foundation ditch peripheral water stopping curtain (supporting) and hole has turned into
The main flow measure of current pattern foundation pit supporting structure, is particularly suited for urban architecture compact district.
Water-stop curtain (supporting) typically uses diaphram wall and interlocking pile, and the construction of diaphram wall is multiple
Miscellaneous, high cost shortcoming limits it and uses on a large scale.Interlocking pile is a kind of new deep foundation pit supporting structure, its
Fast with speed of application, pile quality is high, supporting depth big, can play preferable foundation ditch antiseepage and sealing
The features such as effect, there is good applicability to Deep Foundation Pit Supporting Project.
Existing interlocking pile is using the ultra-retardation concrete stake arrangement side alternate with a reinforced concrete pile
Formula.First ultra-retardation concrete stake is constructed, then construction reinforced bar concrete-pile again, preceding stake uses super slow
Solidifying concrete, it is desirable to the construction of stake after the completion of being answered before the pile concrete is pre-hardening；In rear pile driving construction, use
Tube-in-tube pile machine cuts away the concrete of the part that is in contact with preceding stake, to ensure occlusion.
It can be seen that, traditional interlocking pile has following features:
(1) need using a full set of cylinder method construction
The construction method is constructed using pipe rubbing machine, and complex process, efficiency are low, high cost, is installed and removal set
Cylinder is wasted time and energy, and can produce influence to foundation ditch subsequent job operation, if do not removed (when it is pressed for time), is then made
Cost is improved；Relatively accurate guarantee is difficult into hole perpendicularity；
(2) ultra-retardation concrete is used
Ultra-retardation concrete setting time does not know, it is easy to the situation for causing construction to stagnate, and there is meat or fish pile driving construction
When plain stake freezing problem, pile quality is difficult to ensure that；
(3) constructed in rich water firm hard formation, sleeve pipe is easily bored partially and drilling is difficult, influences the duration.
The content of the invention
It is an object of the present invention to be directed to above-mentioned problem, there is provided aqueous boulder bed and saturation sandstone formation are stung
Close pile construction method.
To achieve these goals, technical scheme is specific as follows：
Aqueous boulder bed and saturation sandstone formation construction method of interlocking pile, it is characterised in that comprise the following steps：
The first step, A types stake 1 is constructed, and the stake is plain concrete pile, using rotary drilling rig pore-forming, rotary drilling rig
Only in aperture mounting portion sleeve pipe during pore-forming, after pore-forming, using full-automatic stake holes inclinometer, inspection
The perpendicularity of stake holes in formation of pile is surveyed, detection pours low-grade concrete in qualified backward hole.
Second step, Type B stake 2 is constructed, and the stake is reinforced concrete pile, by rotary drilling rig, adjacent two
Between individual A types stake 1, using A types 1 pile body of stake of the bit cutting both sides of rotary drilling rig, spiral-digging pore, pore-forming
Afterwards, using full-automatic stake holes inclinometer, the perpendicularity of stake holes, qualified backward Kong Zhongfang in detection formation of pile
Enter steel reinforcement cage, finally inject concrete.
The aqueous boulder bed and saturation sandstone formation construction method of interlocking pile, it is characterised in that described A types
Stake 1, it is specifically poured by low grade plain concrete and formed.
The present invention is for aqueous boulder bed and the technical bottleneck of the occlusion pile driving construction of saturation sandstone formation, Neng Gouyou
Effect ground solves prior art in aqueous boulder bed and the technical barrier of the occlusion pile driving construction of saturation sandstone formation, and
And construction period of interlocking pile is effectively shortened, reduce construction cost.Wherein, one, using churning driven
Machine is constructed, can the pore-forming in aqueous boulder bed and saturation sandstone formation well, and in pore-forming using it is complete from
Dynamic stake holes inclinometer, detects the perpendicularity of stake holes in formation of pile at any time；2nd, because A types stake 1 is using low
Label plain concrete is poured, and when Type B stake 2 is constructed, the element for directly cutting both sides by the drill bit of rotary drilling rig is mixed
Solidifying soil stake, it is to avoid construction that is causing is stagnated because traditional ultra-retardation concrete setting time is uncertain feelings
Condition, it is the necessity of sand pile to also eliminate head stake, duration and expense has been saved, with conventional snap pile driving construction work
Skill is compared, only in aperture mounting portion sleeve pipe during pore-forming of the present invention, without installing a full set of cylinder, construction
Simply, efficiency high, low cost.
Brief description of the drawings
Fig. 1 is construction schematic diagram of the invention.
Specific embodiment
Embodiment 1
As shown in figure 1, aqueous boulder bed and saturation sandstone formation construction method of interlocking pile, it is characterised in that
Comprise the following steps：
The first step, A types stake 1 is constructed, and the stake is plain concrete pile, using rotary drilling rig pore-forming, churning driven
Machine during pore-forming only in aperture mounting portion sleeve pipe, after pore-forming, using full-automatic stake holes inclinometer,
The perpendicularity of stake holes in detection formation of pile, detection pours low-grade concrete, described A in qualified backward hole
Type stake 1, it is specifically poured by low grade plain concrete and formed.
Second step, Type B stake 2 is constructed, and the stake is reinforced concrete pile, by rotary drilling rig, adjacent two
Between individual A types stake 1, using A types 1 pile body of stake of the bit cutting both sides of rotary drilling rig, spiral-digging pore,
After pore-forming, using full-automatic stake holes inclinometer, the perpendicularity of stake holes, qualified backward hole in detection formation of pile
In be put into steel reinforcement cage, finally inject concrete.
Above example is only preferred embodiments of the invention, is not intended to limit the present invention described technical scheme,
