Description
Technical field
The present invention relates to road building machinery field, particularly a kind of for the distribution vehicle containing the construction of sand mist sealing, namely containing sand mist sealing spread equipment.
Background technology
Asphalt concrete road has the advantages such as intensity is high, good stability, day-to-day maintenance are low, is applied in national larger area.Along with the development of China's communication, the increase of vehicle flowrate, overload transportation, asphalt concrete road is after the use of long period, road surface there will be rut, gathers around the diseases such as bag, be full of cracks, smooth surface, and many diseases of flexible pavement all cause because of surface infiltration.Mist sealing sprays the mulseal of thin layer, high osmosis on asphalt surface course, and road surface is closed by the waterproofing course forming one deck tight, is a kind of direct, economy, effectively preventive maintenance working measure, obvious to prolonging service life of pavement effect.
A kind of novel Preventive Maintenance of Asphalt Pavement of Expressway technology containing sand mist sealing, its technique be by have the mulseal of excellent permeability and quartz sand equably spread on flexible pavement, mist sealing material can fill out envelope minute crack and surface void, play waterproof and suppress loose effect, prevent ground surface material aging further, quartz sand can play and improve surface friction coefficient, ensures the effect of traffic safety, is applicable to surface and produces disease and the aging serious asphalt pavement of highway maintenances such as infiltration, oil-poor, microscopic checks.
Two kinds of modes are mainly contained at present containing the spread of quartz sand in sand mist sealing work progress, it is a kind of for quartz sand and mulseal are carried out premixed, then spread is carried out, the bad control of degree of mixedness of which quartz sand and mulseal, and the compound of quartz sand and mulseal is easy blocking pipeline and nozzle in sprinkling process, the asphalt storage on the distribution vehicle that this form of construction work uses needs to configure agitator; Another kind of mode be manually in advance by quartz sand spread on road surface, spray mulseal again, because the spread of quartz sand cannot realize synchronous with the sprinkling of mulseal, so quartz sand cannot be made to inlay in asphalt surface, do not reach anti-skidding order ground, but also there is spread non-uniform phenomenon, in addition, artificial spread efficiency is very low, increases cost of production, add the expense of newly-built asphalt roads and existing asphalt pavement conserving, the second construction method adopts common pitch sprinkling car to realize.More than comprehensive, two kinds containing the equal existing defects of sand mist sealing construction method.
Summary of the invention
The present invention in order to make up the deficiencies in the prior art, provide that a kind of structure is simple, easy to use, compliance is good, can realize mulseal evenly spread synchronous with quartz sand containing sand mist sealing spread equipment.
The present invention is achieved through the following technical solutions:
A kind of containing sand mist sealing spread equipment, comprise asphalt spraying device and quartz sand distributing device, described asphalt spraying device comprises asphalt storage, the front spray arm be connected with asphalt storage by pipeline and rear spray arm, and the pump housing be arranged on pipeline and valve, front spray arm is arranged in quartz sand distributing device front, and rear spray arm is arranged in quartz sand distributing device rear.
Quartz sand distributing device comprises the feed bin, spread valve and the distributing device that hold quartz sand, and the bottom opening that spread valve is arranged on feed bin sentences the aperture controlling bottom opening, and the bottom opening of feed bin is aimed in the import of distributing device; Spread valve opening end and one end are hinged on the spread valve cylinders on feed bin, the fixed end of spread valve is hinged on car body, spread quantity control lever is connected with the feed speed hydraulic cylinder be arranged on feed bin, spread quantity control lever is near spread valve, and the position of spread quantity control lever determines the aperture of spread valve.Spread cylinder is set between distributing device and spread valve.
Feed bin tilt adjustable, by the spread valve that spread valve cylinder controls, the spread quantity control lever controlled by feeding speed hydraulic cylinder, spread cylinder is driven by hydraulic motor, quartz sand is under the spread cylinder effect of self gravitation and rotation, offered on distributing device, quartz sand evenly paves on road surface by distributing device, front spray arm is set before distributing device, rear spray arm is set after distributing device, in work progress, along direction of traffic, first front spray arm sprays a coating emulsified asphalt film on road surface, then spread cylinder and distributing device act on even for quartz sand spread on the mulseal film on road surface simultaneously, after last, spray arm sprays a coating emulsified asphalt in spread again on the quartz sand layer on road surface, quartz sand is fully wrapped up in deposited by two coating emulsified asphalts, impact force in rear spray arm sprinkling process, make the abundant embedded squeezing of quartz sand in road surface minute crack and surface void, the anti-slide performance on road surface is strengthened further.Quartz sand spread quantity is by road speed, spread valve opening, spread drum rotation speed, feed bin pitch angle control.The fountain height of the two groups of spray arms in front and back carries bitumenpump by tractor and controls.The walking of spread equipment provides power by tractor, and required Hydraulic Station and air compressor provide by tractor.
The invention has the beneficial effects as follows, realize the evenly synchronous spread containing quartz sand in sand mist sealing work progress and mulseal, two groups, front and back spray arm is provided with and is beneficial to quartz sand and is mounted in pitch and improves pavement skid resistance ability.Equipment has the advantages such as spread is even, control is accurate, structure is simple, easy to use, easy care, greatly can improve the efficiency containing sand mist sealing construction operation and quality.
