Abstract
The invention discloses a composite structure pile foundation applied to a karst area. The composite structure pile foundation comprises an upper pile section and a lower pile section and is characterized in that the upper pile section is a concrete tubular pile; the lower pile section is a reinforced concrete filled pile and penetrates through a karst cave in a rock layer; the upper end of the lower pile section stretches into the upper pile section to form the composite structure pile foundation. Compared with the prior art, the composite structure pile foundation has the advantages and effects that the upper pile section body is the concrete tubular pile and can be used as a protection cylinder of the lower filled pile section during construction; the cost of the steel protection cylinder in the conventional method in the prior art can be saved; a reinforcement cage and concrete of the lower filled pile section stretches into the upper tubular pile by a proper length, so that the upper section and the lower section are combined to be an integrated pile body and are jointly stressed; the composite structure pile foundation is convenient and quick to construct.
Description
Technical field
The invention belongs to the stake technical field in civil engineering, be specifically related to be applicable to the combinative structure pile foundation of karst region and construction method thereof.
Background technology
When karst area construction building thing bored pile foundation, when boring runs into larger solution cavity, the slurry coat method in often holing runs off rapidly and causes the hole that collapses, and causes any property loss and workmen's injures and deaths, the most also schedule delays.For preventing this type of accident from occurring, it is common practice to squeezing into steel pipe casing as enclosed structure when boring is to scar, this steel pile casting is working measure, and permanent structure stress, it is not intended that it, also cannot be taken out after pile, costly.
Summary of the invention
It is an object of the invention to provide a kind of safe and economical combinative structure pile foundation being applicable to karst region.
For reaching above-mentioned purpose, the technical solution used in the present invention is as follows: be applicable to the combinative structure pile foundation of karst region, including epimere stake and hypomere stake, it is characterized in that: epimere stake is concrete tubular pile, hypomere stake is deposited reinforced concrete pile, hypomere stake, through the solution cavity in rock stratum, becomes combinative structure pile foundation in epimere stake is stretched in hypomere stake upper end.
In technique scheme, epimere concrete tubular pile has reinforced concrete pipe pile, prestressed concrete pipe pile.
In technique scheme, epimere concrete tubular pile is positioned in soil layer.
In technique scheme, epimere concrete tubular pile is precast construction, cast-in-place structural.
In technique scheme, hypomere solid pile is boring, punching, manually digging hole filling pile.
It is another object of the present invention to the construction method of a kind of safe and economical combinative structure pile foundation being applicable to karst region.
In order to achieve the above object, technical scheme is as follows: be applicable to the construction method of the combinative structure pile foundation of karst region, it is characterised in that the method comprises the following steps: A, epimere concrete tubular pile of constructing in overlying soil；B, utilize described concrete tubular pile as casing, hypomere deposited reinforced concrete pile of constructing, make described deposited reinforced concrete pile through the solution cavity in rock stratum, and the upper end of described hypomere deposited reinforced concrete pile is stretched in epimere concrete tubular pile.
The present invention compared with prior art has following advantages and effect: epimere pile body is concrete tubular pile, can also serve as the casing of construction hypomere bored concrete pile when construction, save the steel pile casting expense in current conventional method.Hypomere filling pile cage of reinforcement and concrete all stretch into epimere pile tube suitable length, make upper and lower section to be combined into a common stress of overall pile body, easy construction, quick.The effect of steel pile casting is replaced by the present invention with concrete tubular pile, and this concrete tubular pile can be combined into the common stress of permanent structure with the bored concrete pile constructed below again simultaneously, is therefore a kind of economical and practical piling strtucture, and economic benefit will be apparent upon.
Accompanying drawing explanation
Fig. 1 is pile foundation construction schematic flow sheet.
Fig. 2 is pile foundation organigram.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings.
See Fig. 1, Fig. 2, epimere stake-concrete tubular pile 4 of first constructing in overlying soil 1.The concrete tubular pile that sinking again of can first holing is prefabricated, it would however also be possible to employ cast-in-place method construction concrete tubular pile.Construct again hypomere stake, first carry out boring (rush, dig) hole 5, through the solution cavity 3 in rock stratum 2, after reaching designed elevation, transferring steel reinforcement cage and concrete perfusion, complete the construction of hypomere bored concrete pile 6, two sections of pile foundations have the adapter section 7 of suitable length to be combined as overall common stress.
Epimere concrete tubular pile can be reinforced concrete pipe pile, prestressed concrete pipe pile.Epimere concrete tubular pile is precast construction, cast-in-place structural.Hypomere stake is boring, punching, manually digging hole deposited reinforced concrete pile.
