Concrete pavement crack clearing and filling integrated device and construction method

Abstract

The invention relates to a concrete pavement crack clearing and filling integrated device. The device comprises a movable trolley, an inner crack impurity removing device, a cleaning and brushing device, an air blowing and drying device, a crack filling device, a lifting component and a sludge residue collecting device, wherein the air blowing and drying device, the crack filling device and the lifting component are all arranged on the movable trolley, and the inner crack impurity removing device and the cleaning and brushing device are arranged on the lifting component. The sludge residue collecting device is arranged on the moving trolley and is used for collecting sludge which is cleaned out from cracks by the inner crack impurity removing device. The method has the beneficial effects that crack cleaning and filling can be completed at the same time, cleaned sludge can be collected, walls of cracks the can be dried and the filling depth can be controlled according to different seasons, thus achieving high working efficiency and good quality in crack filling.

Description

technical field [0001] The invention relates to the field of road construction, in particular to an integrated device for clearing and filling joints on concrete pavement and a construction method. Background technique [0002] During the construction of cement concrete pavement, in order to prevent cracks caused by the temperature stress of concrete blocks, shrinkage joints, expansion joints, and longitudinal joints will be left on the concrete pavement, and then the joints will be filled. If the joints are not filled, rainwater will invade the joints and continuously erode the subgrade , the load-carrying capacity of the road decreases, causing looseness and hollowing under the pavement slab, and further diseases such as broken slabs and collapses, so it is particularly important for the quality control of joint filling in road engineering. [0003] The current existing construction technology usually has the following defects: [0004] 1) If the seam cleaning is not clea...
