Abstract
A method for constructing anchor rod by dual-casing method includes drilling a big hole, driving an external pipe into said big hole, fixing it with fixing bars, drilling hole for anchor rod via the external pipe, inserting internal pipe in it, fixing its upper end to said external pipe, inserting reinforcing bars for anchor rod, pouring cement mortar, and pulling the internal and external pipes out. Its advantages are short period, low cost and high safety. It is suitable for macadam stratum.
Description
Technical field
The present invention relates to a kind of method, belong to ground and Foundation Design technical field, the job practices of particularly a kind of anti-float anchor rod and pattern foundation pit supporting structure anchor pole with anchor bolt construction by double sleeve.
Background technology
The job practices of anti-float anchor rod and pattern foundation pit supporting structure anchor pole is all to hole to projected depth by anchor pole design aperture at present, lays anchor pole muscle, perfusion mortar then, forms anchor pole.But as running into macadam, then be difficult to pore-forming even can't construct during anchor pole pore-creating.Therefore, on the rubble stratum, underground building anti-floating problem adopts large aperture steel concrete anti-floating stake usually; Pattern foundation pit supporting structure then adopts the castinplace pile supporting that the stake footpath is big, spacing is little, quantity of reinforcement is big.There is cost height, long in time limit in said method, shortcoming such as poor stability during construction.
Summary of the invention
The objective of the invention is, overcome anchor pole in the prior art is difficult to pore-forming in macadam shortcoming, propose a kind of method, guarantee that anchor pole can construct in macadam, to reduce construction costs, reduction of erection time with anchor bolt construction by double sleeve.
The method with anchor bolt construction by double sleeve that the present invention proposes comprises following each step:
1, uses greater than the drill bit impact of anchor pole intended diameter and creep into into macropore to certain depth;
2, external diameter is driven in the macropore smaller or equal to above-mentioned macropore diameter, the internal diameter outer tube greater than anchor pole design aperture, outer steel pipe top 10～20cm above ground level fixes steel pipe with fixing muscle;
3, downwards bore bolthole to projected depth by anchor pole design aperture by outer tube with rig;
4, put into pipe in above-mentioned bolthole, diameter of inner pipe is slightly less than anchor pole design aperture, and insertion depth slightly is deeper than macadam, and the upper end of interior pipe is fixed on the outer tube with fixed support;
5, in interior pipe, insert the anchor pole muscle, and the cement injection mortar, pipe and outer tube in extracting form anchor pole.
Outer tube in the said method is a steel pipe, and interior pipe is pvc pipe or book steel pipe.
The method with anchor bolt construction by double sleeve that the present invention proposes has solved anchor bolt construction is difficult to pore-forming in macadam problem.When being used to solve building anti-floating problem, without large aperture steel concrete anti-floating stake, and adopt anti-float anchor rod, thereby the reduction of erection time is reduced cost, the raising working security.This method also can be used for the construction of pattern foundation pit supporting structure anchor pole in macadam.
Description of drawings
Fig. 1 is a construction schematic diagram of the present invention.
Among Fig. 1, the 1st, macropore, the 2nd, outer tube, the 3rd, fixing outer effective fixedly muscle, the 4th, bolthole, the 5th, interior pipe, the 6th, fixing interior effective support, the 7th, anchor pole muscle, the 8th, cement mortar.
The specific embodiment
The construction schematic diagram of the inventive method as shown in Figure 1, at first use greater than the drill bit impact of anchor pole intended diameter and creep into into macropore to certain depth, external diameter is driven in the macropore 1 greater than the outer tube 2 in anchor pole design aperture smaller or equal to above-mentioned big bore dia, internal diameter, the top of outer tube 2 10～20cm above ground level fixes outer tube with fixing muscle 3 then; Press anchor pole design aperture with rig and bore bolthole 4 downwards to projected depth by outer tube 3, in above-mentioned bolthole 4, put into pipe 5, diameter of inner pipe is slightly less than anchor pole design aperture, and insertion depth slightly is deeper than macadam, and the upper end of interior pipe is fixed on the outer tube 2 with fixed support 6; In interior pipe 5, insert anchor pole muscle 7, and cement injection mortar 8, pipe 5 and outer tube 2 in extracting form anchor pole.
Outer tube 2 in the said method can be steel pipe, and interior pipe 5 can be pvc pipe or book steel pipe.
Below in conjunction with description of drawings one embodiment of the present of invention: geological conditions is a macadam for top 3.0m in this anti-float anchor rod boundary of works area, is severely-weathered slate below, and the anchor pole design length is 10m, and the aperture is φ 130.During anchor bolt construction, at first the rig diameter is the drill bit impact boring 1 of φ 150, dark 500mm is driven into steel pipe 2 in the hole 1 steel pipe 3 long 700mm, external diameter 150mm, internal diameter 144mm, at its 2 long 200mm of level welding on the upper end 180mm place outer wall, angle is that 180 ° diameter is a fixedly muscle 3 of Φ 25, steel pipe 2 is exceeded about macropore 1 outer 200mm, prevent that the aperture from caving in.Rig is pressed the anchor pole intended diameter and is bored bolthole 4 downwards to projected depth 10m by steel pipe 2 then.Inserting external diameter in hole 4 is the pvc pipe 5 of φ 120, and insertion depth should slightly be deeper than macadam, pvc pipe end suitable for reading tube wall horizontal aspect punching, insert the bar dowel of 2 Φ 16, form support 6, pvc pipe is fixed on the outer tube 2, prevent broken layer hole wall collapse.Insert 2 Φ, 28 anchor pole muscle 7 by interior pipe 5, cement injection mortar 8, pipe 5 and outer tube 2 in extracting at last form anchor pole.
