Abstract
A method for quickly repairing the damaged pavement of road is characterized by that the original damaged pavement is not further damaged in order to repair it. Its advantages are high speed and smoothness, high compression strength up to 50.4 MPa in 24 hr, no influence on traffic, and low cost.
Description
Quick road repairing method dependent territory wood building highway construction technology field.
At present, China is domestic, so long as the overhaul of old road, no matter no matter be that street or lane are provincial road, road at county level or national highway, it is exactly in a year or so that two is blocked up with soil one, and interrupt suddenly on Hang Zou road for many years, and complaints are heard everywhere for the pedestrian, the exposure during news unit.Domestic in China, so long as road is studied for a second time courses one has flunked, must be the hole, side that irregular pitting plane (cutter) one-tenth of road surface breakage is big.Three or four workmans dug (cutter) not in one day several like this holes.And dig (cutter) cement, the blue or green road surface of warbling of the oriole fragment down, throw away toward roadside one, polluted environment, a highway, a wheat harvesting period are just cut a hole and are finished such hole, and various vehicles can only the left side walking of jolting on the road surfaces in many like this holes with hiding right sudden strain of a muscle, not only slowly but also ruin car.The roadman mends the hole with a period of time again, and the material of filling often is higher than the road surface, and the road that mends is not convenient for walking.In October, 1999, the 4th peasant games in Hebei province are held in the city, and city urban construction bureau has used one month time, spends 50,000 yuan, has repaired 1000 meters Zhen Ninglu, and it is the hole everywhere that a period of time makes on the road, is the road surface fragment everywhere, very difficult walk.How to solve and repair that the road is slow, many, the contaminated environment of spending, influence the problem of traffic, my quick road repairing method that begins one's study.I test in my institute of office earlier.My office's courtyard is hardening of cement, and some holes that differ in size have appearred in the use because of construction quality and several years.Sandy soil during I will cheat with whisk broom are swept only, have washed twice with clear water again, the earth flush away of damaged cement pitted surface, use plain ash (old standard 325 then
#Ore deposit quarrel portland cement (brushed in the hole, makes interior each face in hole all be stained with thin pulp by thin pulp.Then mixed concrete is filled out in the hole, used plain ash floating again with ground.Just came into operation in the hole that mends in second day, effect is very good.After, repeatedly make water glass (Na again
2SiO
3) and calcium chloride (CaCl
2) short cement rapid hardening and pressure test, determine to make to mend the setting accelerator in hole with calcium chloride.And to find out percent concentration be 15% optimum formula.Shanghai Lexicographic Publishing House's the 297th page of " setting accelerator " clauses and subclauses of version " Ci hai " in 1999 are said, " calcium chloride commonly used when the pure concrete of preparation ".I make pressure test with the concrete that 15% concentration calcium chloride water mixes under 13 ℃ room temperature condition, the demoulding in 2 hours, and intensity reached 35.2Mpa (MPa) in 6 hours, 24 hours intensity 50.4Mpa (seeing attached sheet 1), it is broken to bear 10 tons of lorry roll offs.[10 tons of trucks are conducted oneself with dignity 8 tons, overload 10 tons to greatest extent, totally 28 tons of deadweight loadings.2 wheels of propons are whenever taken turns load all more than 1 ton, are decided to be every 1 ton of load, 4 wheels in the every limit of back axle, totally 8 wheels of taking turns during calculating.Every wheel tire is wide 20 centimetres, 10 atmospheric pressure, and heavy duty lands at least 15 centimetres.8 tire heavy duties, 8 * 20 * 15=2400cm that lands altogether
2This bogie trailing wheel is to ground pressure=26000Kg ÷ 2400cm
2=10.83Kg/cm
224 hours intensity of this concrete is 50.4Mpa, that is: 50.4Mpa * 10.2Kg/cm
2Mpa=514.08Kg/cm
2, intensity is far longer than the pressure of 28 tons of truck road pavement.This concrete is than 42.5 of the production of Hebei emerging Ward kind cement Co., Ltd
#(old 525
#) high-early (strength) cement compressive strength is big, slightly inferior to 52.5
#(old 625
#) high-early (strength) cement.(seeing Appendix 2)] this concrete also is not afraid of and freezes, can construct under the temperature condition more than-20 ℃.(with the CaCl of 15% concentration
2The concrete that the aqueous solution is mixed is placed on refrigerator-20 ℃ freezing 30 hours, takes out to be placed on 19 ℃ room temperature or to be placed on 50 ℃ the heating installation, does not collapse not split not crisply, solidifies very firmly in the same old way, and intensity does not subtract.)
The hole of filling and leading up with this concrete, road combines with the road surface flawlessly, and is smooth as mirror.After 24 hours fine earth is swept away, the new and old unanimity in road surface is not seen the vestige of making amends for one's faults.After, this concrete intensity only can increase, and can not reduce, and reached maximum intensity up to 28 days, and the road surface is local damaged from what make amends for one's faults never again.
Look into the Chinese patent net, the patent of quick road repairing method is not arranged.
The purpose of (repairing) road method is mended in invention fast, is to pay wages and reduce labor intensity in order to reduce benefit (repairing) road, and the speed that quickening is mended the road and repaired the roads guarantees The coast is clear, and the raising category of roads makes things convenient for the pedestrian, protects environment, promotes economic development.
Claimed technical scheme is, it is long-pending that (1) no longer enlarges the hole, keeps former hole looks, just dust outwash in the hole, and evenly brushes the technology of the plain grey thin pulp of rapid hardening that the calcium chloride water of one deck 15% concentration mixes.(2) rapidly with the calcium chloride water mixed concrete of 15% concentration, to insert in the hole that brushes the plain grey thin pulp of rapid hardening, compacting flattens.(3) rapid calcium chloride water with 15% concentration mixes 32.5
#Quarrel portland cement plain grey mud in ore deposit is smeared pitted surface equally with the road surface.On the new cement face of mending, sweep away out stria with whisk broom, evenly sprinkle the fine earth of very thin one deck through sieve series with the highway direction.
At present the road surface breakage of sclerosis is that a damaged irregular hole is dug or a cutter squarely when studying for a second time courses one has flunked, again packing material in cheat.Digging the hole wastes time and energy, and it is many to spend, and construction speed is slow, influence traffic.The road surface that digs becomes rubbish, throws away the roadside contaminated environment.
This quick road repairing method does not dig the hole, does not enlarge damaged road surface.The concrete of filling rapid hardening and gaining in strength in the irregular hole, damaged road surface with fixed the lumping together of the flawless dungeon in road surface, is not seen the vestige of studying for a second time courses one has flunked.Its construction speed is fast, coagulated mass, and it is fast to reach intensity, does not influence traffic, economical, laborsaving, quick, free from environmental pollution.After, it is big therefore to locate concrete strength, combines tightly with pitted surface, and the road surface is flat again, and the road surface is damaged from here never again.
Promote the best way of quick road repairing method, be after obtaining license, set up quick road repairing company, after the enterprises registration,, and print publicity materials immediately at each medium sending advertisement, be dealt into leader, leader with specific duties and the budget sector of traffic and urban construction department, to they introduce this obtained the saving money not only of patent, not only fast, quick road repairing method not only solid but also attractive in appearance, contract at a low price and mend the road engineering, benefit the society as early as possible.
