Abstract
Said purposes of the invention are realized through the following methods by drilling rigid rod, anchor and anchor bar into soil, the construction methods includes: the drilling machine, slip castingpump and rigid rod are connected with conical anchor and anchor bar, they are taken into the designed position in geological strata through rotary drilling, the pipe-type rigid pieces recedes out thedrilling machine after casts cement slurry and reaches the design requirements, the rigid pipes, rigid pieces, anchor and anchor bar are leaved in geological strata in situ and solidified with cementslurry and underground sand gravel integrally to form anchor bolt.
Description
Technical field
Patented technology of the present invention relates to the anchor rod construction method that a kind of geotechnical engineering field is used.
Background technology
Enrich the bad geological conditionss such as sand gravel layer silt soil stratum of loose weakness in water content, the conventional anchor pole technology is in construction, creep into difficulty, pore-forming difficulty, the difficulty of casting anchor, slip casting difficulty, the anti-power of dialling are low and be easy to generate the piping accident, and existing routine techniques runs into such difficult problem and can't solve.
The content of invention
The above-mentioned purpose of patented technology of the present invention, in the loose soft stratum of bad geological conditions, kind of a new anchor rod construction method is provided, after this anchor rod construction method adopts and does not need to be drilled to hole and pore-forming, descend complicated technologies such as dowel grouting behind shaft or drift lining in the past again hole, be creep into, pore-forming, slip casting, the disposable simple job practices of finishing of dowel down, solved an above-mentioned various difficult problem and can guarantee construction quality again.
The above-mentioned purpose of patented technology of the present invention is crept into rigid rod, anchor head, dowel by following method toward the soil body and is realized, this job practices comprises that rig, grouting pump and rigid rod link with taper anchor head, dowel, after bringing the design attitude on stratum into by rotary drilling again, withdraw from rig after tubular type rigid member injection cement paste reaches designing requirement, rigid pipe, rigid member, anchor head, dowel are frozen into integrally formed anchor pole from staying the soil layer original place with cement paste and the mixing of underground sand gravel.
The inventive method step is as follows:
Creep into by rig power, make the design attitude in rigid rod, the taper anchor head formation drilling soil body; With the dismounting mode with rigid rod, the taper anchor head separates with rig, and rigid rod and taper anchor head are reserved for one's own use in the ground layer soil body, and mechanical displacement withdraws from, wherein rigid rod is geologic drilling rod, steel pipe, reinforcing bar or steel strand, and described steel strand and ground tackle are locked on the waist rail position; Utilize the SMIS hole of rigid rod to inject cement paste and chemical agent in the hole and in the soil body, SMIS hole cement injection slurries by rigid rod, the limit advances the limit high-pressure rotary-spray certainly and design attitude is crept in stirring, and the method for cement injection slurries is high-pressure rotary spraying method, slip casting paddling process or pressure grout method.The taper anchor head is spirality, umbrella shape, arrow-shaped or barb-shaped.
Above-mentioned anchor pole method characteristics: at the abundant fine sand layer of water content and the soil layer of coarse sand garden gravel, the necessary first pore-forming of routine techniques, thereby being drilled to the hole disturbance is easy to generate sand liquefaction and causes piping sandblast accident, the technology of the present invention need not holed, creep into the rigid rod only import but no export and do not have the slit, creep into the cement paste that is added with accelerating admixture of whitewashing and to be frozen into the water stopping type anchor pole rapidly, high pressure jet grouting, the high pressure pouring slurry can make the anchoring body enlarged-diameter, the function that leading reinforcing sand is arranged, anchor head is that umbrella shape and taper are inserted easily, but be difficult for transfering to, speed of application is fast, at the bottom of the cost, pollution-free and tension is dialled the power height.
Mode below in conjunction with the accompanying drawing example specifically describes this patent.
Description of drawings:
Fig. 1 is: creep into figure, Fig. 2 is: rig withdraws from figure, wherein 1, rig, and 2, rigid rod, 3, mouth spray, 4, the taper anchor head, 5, anchor bar body, 6, rig withdraws from.
Claims (2)
1. the job practices of a self-feeding anchor pile, its step comprises:
A) creep into by rig power, make the design attitude in rigid rod, the taper anchor head formation drilling soil body;
B) use the mode of dismounting with rigid rod, the taper anchor head separates with rig, and rigid rod and taper anchor head are reserved for one's own use in the ground layer soil body, and mechanical displacement withdraws from, wherein rigid rod is geologic drilling rod, steel pipe, reinforcing bar or steel strand, and described steel strand and ground tackle are locked on the waist rail position;
C) utilize the SMIS hole of rigid rod to inject cement paste and chemical agent in the hole and in the soil body, SMIS hole cement injection slurries by rigid rod, the limit advances the limit high-pressure rotary-spray certainly and design attitude is crept in stirring, and the method for cement injection slurries is high-pressure rotary spraying method, slip casting paddling process or pressure grout method.
2. the described anchor rod construction method of root a tree name claim 1: it is characterized in that the taper anchor head is spirality, umbrella shape, arrow-shaped or barb-shaped.
