Description
Technical field
The present invention relates to the construction of shotcrete field, particularly in the civil engineering open excavation, dangerous excavation face is carried out a kind of device and method of concrete spraying support behind excavation, particularly personnel and equipment can not guarantee that safe place carries out the just construction of shotcrete device of spray of loose rock face closure at cavern's roof, high side wall place etc.
Background technology
At present, the shotcrete construction method that extensively adopts is to adopt spray windlass mechanical injection concrete, employing manually to hold the jet pipe sprayed mortar.When adopting existing method and apparatus to side slope scar or cavern's sprayed mortar, spraying machinery or spray anchor worker need to be positioned at high slope or the following injection of crown scar, the broken scar that just has been excavated is swept in high-pressure blast or the punching of high energy concrete material, usually have a large amount of rocks to fly even the appearance of caving in, the Focal drug-block that causes thus, the situation of casualties constantly occur.
According to the national regulation regulation, protect effect and quality for guaranteeing spray, the sprayed mortar nozzle hole need to be controlled at 60 ~ 100cm to the distance of scar, and when that is to say with spray windlass sprayed mortar, the spray windlass is apart from scar 60 ~ 100cm; When adopting the Traditional Man sprayed mortar, the spray anchor worker who holds jet pipe is apart from the about 120 ~ 160cm of scar.Too closely or too far all can cause sprayed mortar off quality and stay larger potential safety hazard.This has limited the scope of activities of sprayed mortar jet pipe.Under this restriction, existing these two kinds of sprayed mortar methods are faced with the technical barrier that can't guarantee construction safety or have a strong impact on the duration in the high-risk excavation face situations such as Mass Near The Top of Underground Cavity.
Therefore, engineering circles need to be sought a kind of shotcrete construction method of locating the personnel that can eliminate or machine security hidden danger at high side wall scar place, Mass Near The Top of Underground Cavity etc.
Summary of the invention
Technical problem to be solved by this invention provides a kind of construction of shotcrete device, the terrain operation for jet pipe can be become far to operate, thus the potential safety hazard of elimination personnel and plant equipment; Further, structure is less demanding for equipment comparatively simply, so that site operation.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of construction of shotcrete device, comprise support, side near scar on the support is provided with backstay, guide peg intersects flexible connection by twisted seat and backstay, the jet pipe that is used for sprayed mortar is connected with the guide peg axially parallel, and guide peg is provided with guide rope.
Described twisted seat is the steel pipe moving fastening.
Described guide peg is positioned at backstay length before less than being positioned at backstay length afterwards.
Described guide rope front end is connected with the afterbody of guide peg.
Described guide rope is the 2-4 root, has at least two back side top from support to walk around.
A kind of method that adopts above-mentioned device to carry out construction of shotcrete may further comprise the steps:
One, support and backstay are set;
Two, jet pipe is connected with guide peg;
Three, guide peg is movably attached to backstay;
Four, guide rope is connected to the afterbody of guide peg;
Five, operating personnel are passing through the pulling guide rope away from the position of scar spray plane, and the sensing of traction jet pipe is protected to implement the spray of Mass Near The Top of Underground Cavity and spray plane;
Realize the safe construction of sprayed mortar by above-mentioned steps.
Described guide rope quantity can determine according to spray plane size, when spray plane is larger, can be with 3 ropes when needing on a large scale rotable nozzle, on the contrary can be less than 3.
Described guide rope has at least 2 back side top from support to walk around, when this guide rope of pulling, so that the afterbody of guide peg lifts.
Described flexible connection is to connect guide peg and backstay with the steel pipe moving fastening, so that guide peg can swing, and can backstay be that rotate in the center of circle.
A kind of construction of shotcrete device provided by the invention by adopting above-mentioned structure and method, has guaranteed under high-risk environment excavation face is carried out the safety of equipment and personnel in the concrete spraying support construction.Be a kind of epochmaking that Traditional Man spray is protected, mechanical spray protects replenished, it has remedied the deficiency that personnel, plant equipment can't safe constructions, and the security risk of traditional shotcrete construction process is avoided fully.Device and method of the present invention is particularly useful for that limit crown spray in the cavern excavation process is protected, the preliminary sealing spray during local landslide is protected, and has filled up the blank on these position shotcrete construction methods.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is process flow diagram of the present invention.
Fig. 2 is that the master who installs among the present invention looks schematic diagram.
Fig. 3 is the schematic side view of installing among the present invention.
Among the figure: support 1, backstay 2, jet pipe 3, guide peg 4, guide rope 5, sprayed mortar 6, scar 7, spray regime line 8.
The specific embodiment
In Fig. 2,3, a kind of construction of shotcrete device comprises support 1, and the side near scar 7 on the support 1 is provided with backstay 2, and guide peg 4 is by twisted seat and backstay 2 activity interconnections.Described twisted seat is the common steel tube moving fastening, and namely universal card commonly used easily obtains at the construction field (site).
