Construction process of the present utility model is as follows:
1, surveying setting-out:
The feature of incorporation engineering, by the height of survey grid rank and specifically in the application of engineering different sites, engineering surveying control network arranges plane/elevation one-level SURVEYING CONTROL NETWORK and two grades of SURVEYING CONTROL NETWORK.
2, shown in composition graphs 3, the technical process of chemical anchor bolts and key points for operation:
(1) technical process:
Boring �� clear hole �� insert medicament pipe �� bore into bolt �� gelation process �� process of setting �� fixed object.
(2) key points for operation:
1. hole:
First according to design requirements, position is reserved by drawing spacing (distance between adjacent crab-bolt axis), back gauge (crab-bolt axis is to the distance at the free edge of component), base material is holed, by design bolt model, installation parameter table according to bolt determines aperture, hole depth, determines the drilling depth needed by crab-bolt type and size. The selection of screw rod model to be met the requirement of anchoring thickness, and anchoring thickness equals by the thickness of anchoring object.
2. clear hole:
Use air pressure blowpipe, floating dust in hole is removed, clean in retaining hole.
3. medicament pipe is inserted:
In hole clean for the insertion of medicament pipe, during insertion, will ensure that resin can flow when hand temperature as honey, can make with medicament pipe.
4. bore into bolt:
] a. electric drill screws in screw rod, till medicament flows out.
B. electric drill uses the supporting electric drill (possess boring and screw in the dual-use function of screw rod) that producer provides, and drilling speed is 750n/min.
C. bolt screws in, and medicament pipe is broken, resin. Solidifying agent and quartz particles mixing, and fill the hole between crab-bolt and hole wall.
During the wet hole that d. insertion of medicament pipe is clean, in hole, water must discharge boring, but the waiting time of gelation process and process of setting must double.
5. gelation process:
Setting tool is kept not move. Chemical time is not less than specification and wants seeking time.
6. process of setting:
Take off setting tool and wait for medicament hardening quietly.
7. fixed object:
After medicament hardens completely, add upper gasket and hex-nut fixed object.
3, pull-out test:
Install to reach after design strength requires until chemical anchor bolts and carry out pull-out test by specialty detection unit according to anchorage depth, anchoring thickness and ultimate bearing capacity, sampling group number is chosen by the higher value of 1/1000 and 3, and on-the-spot selection three place's head plate chemical anchor bolts carry out pull-out test. Pull-out test flow process:
(1) from instrument container, take out instrument, connect screw block and anchor pole drawing instrument;
(2) first opening force value display instrument, reset, and click peak value button, close oil-closing valve, empty load pressurization, it is determined that instrument uses normal, then opens oil valve, makes screw block reinstatement;
(3) for the specification of reinforcing bar or crab-bolt, corresponding ground tackle is chosen, (if crab-bolt, corresponding crab-bolt joint should be chosen and screw);
(4) screw block is inserted in crab-bolt to be checked, closes oil-closing valve, with the tight reinforcing bar of ground tackle anchor, slowly pressurize, until there is no space (having slight firmly sense on hand) between screw block and metope, at this moment, pressurization should be stopped, and clicking clearing button and reset;
(5) uniform load force value, meets and exceeds design force value, and stopping pressurization, clicks peak value button, and the force value that record loads waits 2 minutes, and then records force value now;
4, WATER REPELLENT:
Adopt sealing ointment that head plate and ground-connecting-wall junction are carried out waterproof construction.
(1) service tool base cleaning instrument: spade, broom, wire brush, metal bucket, iron spoon, iron pot, waddy, three conjunction scraper plate or plastic scrapers, scrapers etc.
(2) basic level requirement construction surface must be dry, it is desired to base face water ratio is not more than 9%, and with the logical brush of wire brush, thoroughly removes floating ash.
(3) liquefaction cream is endured: waterproofing unction belongs to heat construction water-proof material. Will product external packaging remove after be positioned in iron pot, slowly heat up, limit heating edge constantly stirs, careful anti-burn caking and become waste product, it is warming up to 100 DEG C-110 DEG C, when product surface black becomes clear, fully dissolves, constant temperature can be constructed, and will affect cohesive strength when material is below 80 DEG C. (when enduring liquefaction cream, forbid emitting in pot tobacco, after stopping work every time, be bonded in the ointment defective material endured on pot processed and answer scraped clean, in order to avoid affecting quality when dissolving ointment next time).
(4) panel seam is filled out: before the cementation of fissures, should clean out in seam, first embed in seam with fiber crops muscle, then painting is repeatedly scraped with a small amount of ointment scraper, scraper-trough conveyer on slot both sides, again ointment being divided to fill out for twice is embedded in seam, itself and parietal suture are cohered firmly, presses densification real, prevent ointment from leaving space with seam wall or entraining into air.
(5) ointment construction: waterproofing unction selects single painting, falls ointment on construction basic unit face when list is coated with, uses scraper plate brushing, strike off its thickness, and its thickness should meet design requirements.
5, perforation plug welding:
Strengthen supporting plug welding mode of boring a hole between leg and head plate and horizonal base plate and carry out anchoring.
When the bracing members assembled stage, part workmen can carry out strengthening supporting the work of leg erecting and welding, and the workmen strengthening supporting leg welding all needs to take appointment with certificate. First with slate pencil, built-in fitting is drawn pre-welding to strengthen supporting leg position, leave mark, and check level with water level gauge. Again reinforcement support 200mm place, leg short limit and built-in fitting being carried out completely soldered connecing, weld bead height must meet design requirement. 300mm place, long limit level bar is measured, it is ensured that strengthens supporting leg and is horizontal, to improve stationarity, the fixing of bracing members. While when excavating the first layer earthwork, the groove below built-in fitting is also together outputed, generally it is excavated to lower about 1.0 meters of built-in fitting.
6, the installation of bracing members:
After head plate and reinforcement support leg install, get final product the bracing members of erection stress make-up system, screw block is lifted in controlling box, connect oil pipe and data transmission line, subsequent construction work can be carried out.
More than show and describe ultimate principle of the present utility model and main characteristic sum advantage of the present utility model. The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
