A crawler type spreading machine for rolling core walls of asphalt concrete in the hydraulic engineering

Abstract

A crawler united paver for rolling asphalt concrete is prepared as setting infrared heating unit and insulated hopper of asphalt mixed material at host head; setting alignment monitoring unit at connection point of infrared heating unit and host; setting shock-ironing plate and frame die at host back, riding transition material sub hopper on frame die and setting scraper, scraper lifting up and lowering down unit and receiver of laser leveling unit at back of transition material sub hopper.

Description

Technical field [0001] The invention relates to a roller compacted asphalt concrete paving and construction machine for an anti-seepage core wall of an earth-rock dam, in particular to a hydraulic roller compacted asphalt concrete core wall crawler type combined paver. Background technique [0002] The core wall roller compacted asphalt concrete paving machine is the key machine for the construction of the roller compacted asphalt concrete anti-seepage core wall of the hydraulic earth-rock dam. The paving construction of the domestic hydraulic earth-rock dam core wall roller compacted asphalt concrete and transition material relies on imports. Equipment solution, only a few large companies abroad can manufacture roller compacted asphalt paver for hydraulic earth-rock dam impervious core wall. The price and maintenance cost are high, which increases the engineering cost of the construction unit. Moreover, the maximum thickness of the asphalt mixture paving machine for the anti-see...

Problems solved by technology

[0002] Core wall roller compacted asphalt concrete paving machinery is the key machine for the construction of hydraulic earth-rock dam RCC anti-seepage core wall construction. The paving construction of domestic hydraulic earth-rock dam core wall RCC and transition materials relies on imports Equipment solution, only a few large foreign companies can manufacture hydraulic earth-rock dam anti-seepage core wall roller compacted asphalt concrete paver, its price and maintenance costs are high, which increases the project cost of the construction unit

Moreover, the maximum thickness of asphalt mixture paving of earth-rock dam anti-seepage core wall roller compacted asphalt concrete paver produced by foreign manufacturers is only 23cm, and it does not have temperature detection, electric control ignition, mixture insulation and heating power adjustment according to heating temperature, etc. At the same time, it is difficult to operate the transitional material paving width adjustment slide plate, and the transitional hopper car scraper does not have a visual control switch independent of the laser control system
