Description
Technical field
The present invention relates to construction engineering technical field, it particularly relates to a kind of anchor pole equipment and armature boring construction party
Method.
Background technology
Anchor pole is the component that pulling force is reached to stable rock-soil layer, and rod body material is done when using steel strand wires or high-strength steel tow
When, also referred to as anchor cable.A kind of component in current foundation ditch, slope retaining, generally with campshed, diaphragm wall or soil nail wall phase
With reference to as main primary structure member;Traditional anchor pole is the pressure that can only bear very little in work, and applicable situation is limited.
The applicable formation volumes of suspension roof support are wide, almost cover all stratum in China, more than relatively stable level of ground water
Banket for many years, cohesive soil typically uses the dry pore-forming of twist bit, the Chinese patent of Application No. 201310154494.4 discloses
A kind deep foundation pit soil layer suspension roof support construction technology, comprises the following steps:(One)Telephone-moving is in place;(Two)Correct hole position
Align angle;(Three)Drilling;(Four)Grouting;(Five)Put anchor pole;(Six)Pull out outer tube;(Seven)Waist rail is installed;(Eight)In advance
Stress tension;(Nine)Anchor pole is examined;The present invention is simple to operate, and cost is cheap, and supporting effect is good, suitable for architectural engineering
Clay, silty clay and containing the relatively low earth-retaining branch of a small amount of sand, stone argillic horizon, the deep basal pit of miscellaneous fill soil property, and level of ground water
Shield.This method is cheap, although being widely used, the stratum that it is applied is limited, has certain limitation
Property.
The Chinese patent of Application No. 201110038905.4 discloses a kind of anti-collapse hole construction method for anchor drilling, bag
Include following steps:A, pit earthwork excavates;B, the cleaning of side slope surface dust, smooth and excavation slope unwrapping wire;Drilling machine is installed c,;D, adopt
Being drilled with a section core bit, the core bit and its drilling rod are hollow types, 90~120mm of drill pipe diameter, length 1.0~
1.2m;E, be arranged on the built-in bit bore of the inside of the core bit using a section, the built-in drill bit be it is solid, its
Drilling rod is hollow, and the drill pipe diameter of the built-in drill bit is smaller 5~8mm than the drill pipe diameter of core bit, length 1.0~
1.2m;F, step d and e are alternately repeated;G, borehole cleaning and whole exit built-in drill bit drilling rod;Anchor cable and Grouting Pipe are installed h,;I, note
Starch and exit drilling rod of coring, drilling rod of coring is exited on marginal not slurry side, often exit a section core drilling rod with regard to ftercompction slip casting once;J, whole
Exit the drilling rod and ftercompction slip casting is once again of coring.Although this method can be applicable various stratum, ensure that hole wall does not cave in, effect compared with
It is good, but cost is high, cost is too high.
