Abstract
The invention provides a construction method for an anchor rod for civil engineering. The construction efficiency is high, mud and vibration are avoided, the stability performance of anchor holes is high, the strength of the anchor rod is high, and the anti-puling bearing capability of the anchor rod is high. The construction method comprises the following steps that an eye position is marked through paint; a drilling machine is moved to the preset position, and a drill bit is driven by a drill rod to drill into the eye position; when it is found that drilling is difficult for the drilling machine, the air pressure and the drilling speed are adjusted in time; in the rotating process of the drill rod, the perpendicularity of the drill rod is observed in real time; after the drill bit drills into the position by the preset depth, whether underground water exists in an anchor hole or not is observed, and when a large amount of underground water exists, clean water is injected in the anchor hole, and when no underground water or a small amount of underground water exists in the anchor hole, cleaning is carried out through an air compressor air pipe; quality detection is carried out on a steel bar, and the steel bar is placed into the bottom of the anchor hole in a manual stacking manner; and a grouting pipe is inserted into the anchor hole, grouting is carried out through a grouting pump and the grouting pipe communicated with the grouting pump, and when the grout reaches the designed height, the grouting pipe is pulled out, and the grout and the steel bar are solidified and form the anchor rod.
Description
Technical field
The present invention relates to anchor bolt construction field, particularly relate to a kind of civil engineering anchor rod construction method.
Background technology
All buildings related to are all to high level, deep layer, large area, heavy-duty future development, the application quantity of anchor pole in Rock And Soil stabilization works, support engineering also increasing, range of application is more and more extensive, has important engineering significance and economic worth to the innovation of this field of engineering technology and construction technical method or useful improvement.Present stage anchor rod construction method and operation comparatively loaded down with trivial details, efficiency of construction is lower, and in work progress, anchor pole easily vibrates, and affects the stability of anchor hole, and in addition, anchor rod strength is low, and anti-pulling ability is weak.The problems referred to above need solution badly.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of civil engineering anchor rod construction method, to solve the problems of the technologies described above.
A kind of civil engineering anchor rod construction method that the present invention proposes, comprises the following steps:

S2: rig substructure to precalculated position, and is leveled up by transfer rig, adjustment drill pipe angle, drives drill bit to pierce above-mentioned eye position by drilling rod;
S3: stirred forward by drilling rod rotary drilling-head and creep into, when discovery rig creeps at need, drag for slag in time and sample, and differentiate slag specimen, adjustment air pressure and rate of penetration, guarantee that drill bit enters bearing stratum;
S4: in drilling rod rotary course, real-time monitored drilling rod verticality, adjusts in time when deviation appears in drilling rod;
S5: after drill bit pierces desired depth, with or without underground water in observation anchor hole, when underground water is more, injected clear water in anchor hole, flows out till clear water in anchor hole, when in anchor hole without underground water or underground water less time, adopt air compressor air pipe cleaning, take away the residue in anchor hole;
S6: carry out quality examination to reinforcing bar, guarantees that rebar surface is without after dirt or scar, adopts artificial mode of stacking to transfer to anchor hole by reinforcing bar;
S7: Grouting Pipe inserted in anchor hole, the Grouting Pipe be communicated with it by grouting pump carries out slip casting, when slurries reach design height, extracts Grouting Pipe, and slurries and reinforcing bar solidify, and form anchor pole.
Preferably, in drilling rod rotary course, compass is adopted to check drilling rod verticality.
Preferably, above-mentioned grouting pump is high-pressure grout injector.
Preferably, above-mentioned slip casting process without pause, and adopts plummet to calculate pulp level.
A kind of civil engineering anchor rod construction method that the present invention proposes, efficiency of construction is high, and without mud, friction, anchor hole stability is good, and anchor rod strength is high, and anchor pole anti-pulling capacity is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of civil engineering anchor rod construction method that the present invention proposes.
