Abstract
The present invention relates to prevent the internal spray repairing method and the equipment of house chimney smoke leakage.This restorative procedure comprises the preparation of coating, flue pipe clean the main process of the spraying of coating with water.The coating that is adopted is to be mixed by cement, sand, water, adhesive and air entraining agent.Be the enforcement of this method, adopted crucial head and the lance head equipment cleaned with water.
The present invention have efficiency of construction height, cost low, house integral structure is not had destruction, advantage such as protected house self shock resistance, do not disturb residents, its economic benefit and social benefit are all good.
Description
The invention belongs to maintain houses and buildings flue job practices and equipment.
The house has flue now, be by pipe of cement mostly, or vitrified-clay pipe, or inorganic pipe constitutes, the flue that is made of these material pipes, or because construction reason, and the not tight and dislocation of the interface that causes pipe, or because the material etch resistant properties of pipe own is poor, and produce breakage, crackle, pit, these shortcomings all can cause flue generation smoke blowing phenomenon, even can gas poisoning take place and cause the accident of injures and deaths.This chimney smoke leakage gas leak phenomenon, particularly outstanding in the winter in northern China cities and towns, it one of constitutes a public nuisance.
Existing restorative procedure to smoke blowing gas leakage flue, unique way is " a replacing method ".This method is that the flue pipe that smoke blowing is leaked gas is dug from the building wall, all more renew pipe then, the drawback of the restorative procedure of this replacing formula is conspicuous: it is great in constructing amount, long in time limit, the cost height, sometimes need collar tie beam is interrupted, overall structure to the house has destruction, work progress disturbs residents seriously, moreover, because this method is subjected to the restriction of job site condition, the interface of changing the back pipe is difficult to guarantee leakproofness, therefore, still also the smoke blowing gas leak phenomenon can occur, for this reason, the repairerment work of house flue has become real estate management maintenance department a great problem.
The present invention is directed to the existing weak point of changing flue tubular type restorative procedure, and propose a kind of internal spray repairing method and equipment, this method is not only time saving and energy saving but also very effective reliable.
One of content of the present invention is the implementation process about internal spray repairing method.This process comprises coating preparation and implements spraying two big steps, divides and cleans and spray two procedures with water, this method of the present invention and spray step.Its key technology is the compound method of coating.Two of content of the present invention is about guaranteeing the enforcement of internal spray repairing method, the mechanical equipment configuration that is adopted, and in the middle of the plant equipment that adopts, its key equipment is to clean with water head and lance head.
Accompanying drawing 1 is the mechanical equipment configuration schematic diagram that the invention process spraying process is adopted.Accompanying drawing 2 is to clean the header structure schematic diagram with water.Accompanying drawing 3 is blackwash sprayer header structure schematic diagrames.Each title and effect are among the figure: 1 is lance head, and it is to be made of conical shell 10, and this cone taper is 1: 5.5, and its garden offers on week by certain regularly arranged φ 4 apertures.Lance head is driven by high-speed pneumatic motor 2 and rotates, can be with paint spay-coating on the flue pipe inwall.The 3rd, blast pipe, its outer end links to each other with air compressor, and pressure-air is supplied with air motor by it.4 for being coated with material conveying tube, and its end links to each other with slush pump 9, and the other end links to each other with lance head.5 is directive wheel, its role is to the inclination pulling force of elevator is changed over the pulling force of vertical direction.6 is elevator, with the pulling force of its generation, by directive wheel 5, affect air motor and clean head with water, or air motor and lance head be along moving up and down in the flue pipe, 7 is reductor, 8 is motor, and 9 is slush pump, and 10 is the housing of lance head, 11 is brush body, it is a little short garden post housing, is shaped on wire brush thorn 12 on it, and this brush thorn is when off working state, be vertical downward direction, 13 is compressor.
Specific implementation process of the present invention is: first step carries out the coating preparation.Cement, sand, water, adhesive, air entraining agent are pressed column weight amount percentage mix:
Cement: 25-30%
Sand: 20-30%
Adhesive (107 glue): 10-15%
Air entraining agent: 3-5%
All the other are water
Second step sprays.It is very important before the spraying flue being cleaned with water.Cleaning head height speed with water by the air motor drive rotates, and by elevator affect air motor and clean with water the head in flue, move up and down, then can dispose fouls such as dust stratification on the walling of flue, coal tar, sulfide, oxide, expose to reach to clean with water more than 90% when the mother metal surface of flue pipe and stop, can spraying then.At first be the spraying of carrying out bottom, start slush pump, in conveying pipeline was delivered to lance head, lance head then can be sprayed on coating on the flue pipe inwall, at this moment under the air motor of high speed rotating drives equably with the coating for preparing.Under the traction of elevator, lance head remakes vertical direction and moves, so can spray the bottom that thickness reaches 1-2mm equably in whole flue pipe, the interval is 3-5 hour then, the spraying on beginning top layer, its spraying method is identical with the bottom spraying method, and this skin depth is advisable at 2-3mm.Flue pipe after cleaning with water is through above-mentioned twice spraying; so just just having formed one in flue pipe is the monolithic devices lining pipe of main material with cement; its thickness can reach 5-6mm; such lining pipe can be realized the interface slit to flue pipe on the one hand; or the filling up of shortcomings such as the crackle of pipe, pit; reach the purpose of envelope cigarette gas shutoff, the aspect has played the effect of giving anti-protection again to whole flue in addition.
The embodiment of the invention is as the criterion to repair a certain building, Hebei road, peace zone, Tianjin building flue relevant data.
Coating preparation: (percetage by weight)
Cement: 30%
Sand: 30%
Adhesive (107 glue): 10%
Air entraining agent: 5%
All the other are water
Sprayed coating thickness: 5-6mm
Flue height: 20m
Activity duration: in October, 92
The present invention has the efficiency of construction height, and cost is low, and quality is good, and house integral structure is not had destruction, has protected self shock resistance in house, and advantage such as do not disturb residents in the construction.Work efficiency of the present invention is existing restorative procedure work efficiency 30-50 times, and the cost expense only is 1/2-1/3, does not disturb residents in the construction, is subjected to very much resident's welcome and support, so the present invention has good economic benefit and social benefit.
