Abstract
The utility model belongs to building engineering's secant pile, a concretely relates to single pile reducing inlay rock secant pile. This secant pile's soil layer section is the same with the diameter of rock upper segment and be greater than the rock hypomere diameter of stake, and the rock hypomere diameter of stake equals with the stake diameter with the design that the segment length be 100~5000mm on the rock of stake, and the soil layer section of stake and the diameter of rock upper segment are greater than the 50~200mm of rock hypomere diameter of stake, and length is used for designing to the segment length under the rock of stake. The utility model discloses simple structure can guarantee construction quality to can improve the efficiency of construction.
Description
Technical field
This utility model belongs to the interlocking pile of architectural engineering, and in particular to a kind of embedding rock interlocking pile of single pile reducing.
Background technology
Hole-drilling interlocking pile refers to that adjacent studs are mutually twisted between the campshed of horizontal layout（Stake circumference is mutually embedding）And the reinforcing bar for being formed
Concrete " piling wall ", it is used as the deep foundation pit supporting structure of structures, in cities such as subway, road underpass, high-rises
It is widely popularized in the deep-foundation pit engineering of structures, is particularly well-suited to the ground of the bad conditions such as mud, quicksand, subsoil water enrichment
Layer.
After the concrete final set of interlocking pile occurs in the occlusion of stake, become seamless continuous " piling wall "；It and common bore
Hole retaining piles are compared, and shearing strength and the safety of supporting construction is greatly improved；It has the good performance that intercepts water, no
Commonly need to drill campshed auxiliary intercept water and stake between the native measure of gear.Seamless continuous " the stake that hole-drilling interlocking pile is formed afterwards " occlusion "
Wall ", determines that its construction equipment must be using retaining wall.
But in actual construction, lithosphere and solution cavity of unexpected certain depth etc. under soil layer is frequently run onto,
If being continuing with all casing drill, creep into highly difficult, construction speed can slow down significantly.Some units in charge of construction are for journey of overworking
Progress, will continue drilling, such as Spiral digging machine, down-hole hammer, impact drill etc. using embedding rock equipment.Due to the construction of embedding rock equipment
Diameter（The diameter of i.e. embedding rock drilling tool）The both less than steel bushing pipe diameter of all casing drill, so can be little in the aperture of rock section drilling
In the standard design aperture of soil layer section, the occlusal layer for soil layer section often occur after being cast into continuous interlocking pile meets engine request,
And the occlusal layer of rock section is often not enough, or even it is not engaged at all, result in it cannot be guaranteed that construction quality, has potential safety hazard
The problems such as.
Utility model content
For the various defects for overcoming existing above-mentioned concrete interlocking pile to exist, this utility model is it is intended that provide a kind of single
The embedding rock interlocking pile of stake reducing, the diameter change up and down of concrete interlocking pile, and the interlocking pile centre-to-centre spacing for designing still keeps constant, its
Simple structure, construction are easy, it is ensured that rock section has enough occlusion thickness, it is ensured that construction quality.
Solving the technical scheme adopted by its technical problem is：Rock section diameter of the soil layer section of stake with diameter greater than stake, and
The rock section diameter of stake uses stake equal diameters with design.After being expanded by the stake footpath by soil layer section, although the occlusion of soil layer section
Thickness degree has part to increase, and the consumption of concrete is also increased, but ensure that stake footpath and the occlusal layer thickness of rock section
Also ensure that the construction quality of whole interlocking pile.
The rock hypomere 50～200mm of diameter with diameter greater than stake of the soil layer section of described stake and rock epimere, the rock of stake
On stone, segment length is 100～5000mm, and under the rock of stake, segment length is design length.The data ensure that can be expeditiously
Embedding rock operation is carried out, makes the occlusion thickness of rock section reach design standard, although while the consumption of concrete is in soil layer section and rock
Stone epimere has increased slightly, but ensure that the construction quality of interlocking pile.
The beneficial effects of the utility model are：As drill machine with casing has used the specialized barrel of diameter increase, rock section is made
Stake footpath and occlusal layer thickness can relatively easily reach design standard, define up big and down small single pile reducing interlocking pile, protect
Having demonstrate,proved has occlusion and thickness enough in rock section, also ensures that construction quality；Rational interlocking pile is employed in soil layer section
Expanding data, therefore the embedding rock operation in rock section becomes to be easier to, and improves work efficiency, while and by soil layer section concrete
Consumption control in relatively inexpensive scope.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is overlooking the structure diagram of the present utility model.
In figure：Soil layer section stake 1, rock epimere stake 2, rock hypomere stake 3, rock hypomere occlusal layer 4, top occlusal layer 5.
Specific embodiment
Below in conjunction with accompanying drawing embodiment, it is further described to originally new.
Referring to each figure, the diameter with diameter greater than rock hypomere stake 3 of the soil layer section stake 1 and rock epimere stake 2 of interlocking pile, and
The stake diameter and design for ensureing rock hypomere stake 3 uses stake equal diameters, so as to ensure that rock hypomere occlusal layer 4 has qualified stinging
Close thickness, it is ensured that the construction quality of whole interlocking pile, that is, the interlocking pile centre-to-centre spacing for designing is constant, and 1 He of soil layer section stake
2 enlarged-diameter of rock epimere stake, defines the embedding rock interlocking pile of single pile reducing.Soil layer section stake 1 and rock epimere stake 2 with diameter greater than
50～the 200mm of diameter of rock hypomere stake 3, stake holes keep 100～5000mm of isometrical extension in rock epimere first, then press again
The diametric requirements of design stake, embedding rock reach projected depth, it is ensured that can expeditiously carry out embedding rock operation, although sting on top
The concrete amount for closing layer 5 has increased slightly, but quality is guaranteed.
When the construction method of this embedding rock interlocking pile is to run into the geological condition of soil lower rock, wall is led in floor manufacture first,
Then using the special steel pipe of expanding 50～200mm, sleeve pipe, immersed tube etc. is carried out with drill machine with casing in soil layer section and rock epimere
Sequence of maneuvers, until it reaches 100～5000mm of lithosphere, is fetched earth and is taken rubble operation.Embedding rock instrument is changed after fetching earth（Such as
Rotary digging equipment, down-hole hammer, impact drill etc.）Embedding rock operation is carried out, after embedding rock reaches projected depth and aperture, lashing hypomere stake
Stone in 3 stake holes, is put into steel reinforcement cage（Or direct placing concrete）, placing concrete extracts steel thimble, carries out next stinging
Close the construction of stake.
