Description
Technical field
The invention belongs to anchorage stake interconnection technique fields, and in particular to the multi-functional anchoring waterproof construction of one kind and its anchoring side
Method.
Background technique
Recently as expanding economy, the urban construction and development in China is also abnormal rapid.From high-rise, super high-rise building to
Construction of Urban Rail Traffic, relevant underground engineering is more and more, has emerged a large amount of deep-foundation pit engineering.Using anchor structure
Support system as foundation pit.Anchor structure is the novel technique that the realm of building construction generates in the past 20 years, is answered extensively
For underground structure construction supporting system and make the tensile member of permanent construction structure.Pulling and arching supporting structure is mainly by enclosing
Protection structure system and anchoring system two parts composition.Tensile anchor aground type needs enough place setting anchoring piles or other anchorings
Object.Anchor rod type needs foundation soil that can provide anchor pole biggish anchor force.Anchor rod type is relatively suitable for sand foundation or clay foundation.
In order to meet the force request in excavation of foundation pit stage, in excavation of foundation pit, the concrete support of first time is first done, is made
Work is excavated constantly to carry out.First time supporting only guarantees to excavate the ongoing safety measure of work.If foundation pit earth
When pressure is larger, also to apply second of supporting can guarantee the overall stability of foundation pit.When foundation pit is in rich water area,
Splash guard laying is also done between first time supporting and second of supporting.To guarantee second of the supporting applied and propping up for the first time
Horizontal reinforcement and pre-buried straight thread steel will be also arranged in the globality of shield and country rock in second of supporting and first time braced wall
Muscle connector, reinforcing bar is connected by connector with first time supporting reinforcing bar in second of supporting.
But a large amount of case history explanation, anchor pole country rock, first time supporting and second of supporting formed one it is stable
Meanwhile also splash guard is punched, water just along the radially and longitudinally percolating water of anchor pole, cause concrete guard wall strength reduction and
Drainage endangers building.Simultaneously when applying second of supporting, for guarantee concrete formation, need on the outside use pair
Pull rod and outer support fixed form, cause space in foundation pit largely to waste, using such connection type, not only construction efficiency
It is low, and material is wasted, it increases the labor intensity of workers.
Summary of the invention
The purpose of the present invention is to provide a kind of multi-functional anchoring waterproof construction and its anchoring process, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the invention provides the following technical scheme: a kind of multi-functional anchoring waterproof construction, including foundation pit
Country rock and threaded anchor rod, the surface of the foundation pit country rock have poured first time branch sheath, and the surface of the first time branch sheath is set
It has been friends in the past splash guard, one end of the threaded anchor rod sequentially passes through old splash guard, first time branch sheath and foundation pit country rock, the screw thread
The end of anchor pole is fixed in foundation pit country rock, passes through the first nut on the threaded anchor rod for waterproof washer and the first metal washer
It is successively pressed on the surface of old splash guard, threaded sleeve, the threaded anchor rod has been connected through a screw thread on the threaded anchor rod
The other end the second metal washer and the second nut are installed.
Preferably, the waterproof washer is fitted closely with old splash guard.
Preferably, the old splash guard is integrally laid in first time supporting layer surface.
Meanwhile the invention also discloses a kind of anchoring process of multi-functional anchoring waterproof construction, including following operating procedure:
S1: installation threaded anchor rod successively drills out anchor in old splash guard, first time branch sheath and foundation pit country rock using drilling machine
Threaded anchor rod is inserted into rockbolt installation hole after grout injection, to cement slurry sets by bar mounting hole again in rockbolt installation hole
It completes to fix afterwards；
S2: water-proofing treatment is elapsed by collision mat snare on threaded anchor rod and by waterproof washer to old splash guard first
Surface is bonded, then is heated using flame gun to waterproof washer and old splash guard joint bright eruption so that waterproof washer and
Old splash guard hot melt fitting, is inserted in the first metal washer later and the first metal washer is pressed on collision mat using the first nut
On circle；
S3: threaded sleeve is rotated to the appropriate location of threaded anchor rod, then covers cope plate by installation template, passes through rotation the
Two nuts are fixed up the second metal washer and threaded sleeve template, carry out concrete pouring operation later.
Preferably, the heating temperature of step S2 Flame spray gun is 1000-2000 DEG C.
Preferably, old splash guard and waterproof washer are the identical waterproof roll of material in step S2.
Technical effect and advantage of the invention:
1, by this device, foundation pit country rock, first time branch sheath and second of branch sheath can closely be contacted one
It rises, whole stress is more firm；
2, by this device, foundation pit, Lock gate liner can be integrated, avoid when performing load bearing wall in the later period
Apply waterproof roll, accelerates construction progress；
3, by this device, it can save and need formwork because inner lining concrete pours and use to pull rod or template,
Construction space is saved, working efficiency is improved；
4, by this device, after inner lining concrete conserves, form removable can be recycled, saves cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
