Description
Technical field
The utility model relates to subway station side wall waterproof field, is specially net spray leveling layer self waterproof structure between the stake of a kind of subway station.
Background technology
China's city underground is just entering construction high-tide period, and station construction waterproof is one-level, requires that the complete rear agent structure of station construction is without wet stain.But, station space enclosing structure adopts boring interval stake mostly at present, the outer precipitation in hole is adopted during excavation, need to carry out sprayed mortar between stake, lay waterproofing course after needing to carry out mortar levelling before main body construction, this conventional method not only affects main body construction progress, and leveling layer easily falls block and affects waterproofing course laying quality, add self hole of online spray more, finally cause main body to seep water serious.Also do not have a kind of method and device can realize both not only having affected main body construction progress at present, do not affect waterproof quality again.Subway station side wall water-proof leveling layer is worth research.
Summary of the invention
The utility model, in order to solve that net between the stake of existing station is sprayed with penetrating passage, water-proof leveling layer affects main body construction progress and the difficult problem such as waterproofing course laying quality difference, provides net spray leveling layer self waterproof structure between the stake of a kind of subway station.
The utility model adopts following scheme to realize: net spray leveling layer self waterproof structure between the stake of a kind of subway station, comprise interval and be anchored at dowel on each fender post, all dowel length exposing to fender post is identical, end, dowel outer end is welded with reinforced mesh, the concrete ejection anchor layer equal with reinforced mesh is provided with between adjacent fender post, concrete ejection anchor layer trypsin method has cement-base infiltration crystallization coating waterproof layer, is provided with the floating layer of cement mortar outside cement-base infiltration crystallization coating waterproof layer.The concrete of rapid setting cement and expansive cement preparation adopts conventional concrete spray technology to be formed by described concrete ejection anchor layer, and described cement-base infiltration crystallization coating waterproof layer adopts conventional spray paint technique by well known materials cement based penetration crystallization type water proofing paint and formed.
The described dowel length exposing to fender post is the thickness of concrete ejection anchor layer.
Described concrete ejection anchor layer thickness is 3 ~ 5cm, and the thickness of cement-base infiltration crystallization coating waterproof layer is 1 ~ 2cm.
First, invade sunken fender post by measurement processing after excavation pit, then, stake is holed rear rapid setting cement and expansive cement anchor bar net, and sprayed mortar; Last at sprayed mortar face spray cement based penetrant crystalline coating, final cement mortar is floating, forms water-proof leveling structure.
Compared with prior art, the utility model has the following advantages:
1) by rapid setting cement and expansive cement anchor bar mesh sheet in stake, and reinforced mesh is fixed on the identical fender post dowel of protruded length, substantially increases the planeness of concrete ejection anchor layer, reduce net spray springback capacity, accelerating construction progress;
2) after the initial set of concrete ejection anchor layer, spray cement based penetrant crystalline coating, then cement mortar screeding, realizes net spray and the one-shot forming of water-proof leveling layer, reduces working procedure;
3) adopt cement-base infiltration crystallization dope layer and cement sand bed levelling to anchor layer, not only strengthen anchor layer and leveling layer adhesion stress, and achieve the closely knit impervious effect of net spray, also self-regeneration hole is carried out to leveling layer, substantially increase waterproof action, stop the infiltration of main body later stage;
In a word, it is easily levelling and improve the advantages such as waterproof effect that the utility model to make full use of after sprayed mortar initial set spray cement based penetrant crystalline coating mortar, not only simplify working procedure, reduction of erection time, and improve waterproof quality, reduce construction cost, there is technique simple, advanced technology, the advantage such as practical, this technology is adopted to have successfully completed Shenyang Metro No. 9 line 7 Biao Wang river way stations and the levelling construction of interval ventilating shaft agent structure side wall waterproofing course, fill up the blank of China's subway station side wall waterproof net spray construction of leveling blanket technology, achieve good economic benefit and social benefit.This practicality is newly applicable to underground all fender post agent structures side wall water-proof leveling layer construction.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model;
Fig. 2 is the utility model vertical section schematic diagram;
In figure: 1-fender post; 2-dowel; 3-reinforced mesh; 4-concrete ejection anchor layer; 5-cement-base infiltration crystallization coating waterproof layer; The floating layer of 6-cement mortar.
Detailed description of the invention
Net spray leveling layer self waterproof structure between a kind of subway station stake, as shown in Figure 1, 2, comprise interval and be anchored at the dowel 2 each fender post 1 with jet thickness mark, all dowel length exposing to fender post is identical, end, dowel outer end is welded with reinforced mesh 3, the concrete ejection anchor layer 4 equal with reinforced mesh is provided with between adjacent fender post, concrete ejection anchor layer trypsin method has cement-base infiltration crystallization coating waterproof layer 5, is provided with the floating layer 6 of cement mortar outside cement-base infiltration crystallization coating waterproof layer.Dowel 2 length exposing to fender post 1 is the thickness of concrete ejection anchor layer 4; Concrete ejection anchor layer 4 thickness is 3 ~ 5cm, and the thickness of cement-base infiltration crystallization coating waterproof layer 5 is 1 ~ 2cm.
During concrete enforcement, comprise the following steps:
Step one, apply steel mesh reinforcement and jet thickness mark
Clearance survey is carried out after A, pit earthwork excavation; B, process is cut to encroachment line stake position; C, rear anchoring dowel of holing on fender post, dowel protruded length is the jet thickness of concrete ejection anchor layer; D, steel mesh reinforcement to be welded on dowel.
Step 2, sprayed mortar are levelling
A, to the position sprayed mortar hanging up properly steel mesh reinforcement; Immediately at its surface spraying cement-base infiltration crystallization coating after the initial set of B, sprayed mortar covering steel mesh reinforcement; C, finally by cement mortar by floating for its surface.
case history
Between a kind of subway station stake, net spray leveling layer self waterproof structure is used in Shenyang Metro No. 9 line 7 Biao Wang river way stations and interval ventilating shaft side wall engineering, between employing stake after sprayed mortar, spray cement based penetrant crystalline coating immediately, and it is floating by cement mortar, not only simplify operation, accelerate main body construction progress, and guarantee waterproof quality, reduce construction cost.Prove this advanced technology, methodological science is reasonable.
This utility model has been generalized in my company's other City Subway Station side wall water-proof leveling layers construction, ensure that construction speed and waterproof quality, reduces construction cost, simplify operation, achieve good economic benefit and social benefit, facts have proved, this technical scheme is practical, and promotion prospect is good.
