Construction method of onsite supply operation for micro surfacing

Abstract

The invention discloses a construction method of onsite supply operation for micro surfacing. The method is characterized by comprising the following steps: firstly, using a batching machine to load mineral aggregate into bulk bags in specific proportion in accordance with the performance requirement, and tieing the ropes of the bulk bags; secondly, using one crane truck to stack the mineral aggregate in bulk bags along the line, and using another crane truck to lift the mineral aggregate in bulk bags onto seal equipment for unloading; thirdly, using an integrated liquid supply vehicle with a liquefied asphalt tank and a water tank to transfer the modified emulsified asphalt and the water respectively into the seal equipment through waste water and a water pump or onsite supply; fourthly, using a jubilee truck to carry the cement to the construction site, carrying out onsite cement supply to the seal equipment with manpower; fifthly, performing paving in accordance with the normal construction procedure, after the paving is finished, supplying the material, and then performing the paving again; carrying out the operation repeatedly until the paving is finished. By adopting the construction method, the construction efficiency can be remarkably improved, the construction quality is ensured, materials and fuels are saved; in addition, the operation is convenient, and the construction is environmental protection.

Description

technical field [0001] The invention relates to highway maintenance technology, in particular to a construction method for on-site replenishment at micro-surfaces, which is especially suitable for preventive maintenance of expressways and first-class highways. Background technique [0002] Those engaged in highway maintenance know that when the pavement anti-slip coefficient or water seepage coefficient decays to the critical value required by the technical specifications of highway engineering, in order to ensure the safety of traffic, delay the water damage of the road, control the further occurrence of road surface diseases and extend the road For a long service life, it is usually necessary to take measures for maintenance. In the prior art, a micro-surfacing construction method is often used. This method is to use a forklift to roughly mix the 3-4 grades of mineral materials in the field after the construction, and then pour them into the sealing car, and then use the s...

Problems solved by technology

The existing micro-surface construction method always has the following disadvantages: one is to use a forklift to manually prepare aggregates, so that the proportion of aggregates in each vehicle has a large difference, and the stability is poor, which affects the construction quality At the same time, it also causes a waste of materials; the second is that there is a certain distance between the construction site and the construction site. In the later stage of construction, the distance is even further, and the sealing vehicle intermittently loads and paves back and forth. Staff layoffs

The construction efficiency is low, and a lot of materials and fuel are wasted
