Automatic tunnel waterproof material laying and hanging construction trolley

Abstract

The invention provides an automatic tunnel waterproof material laying and hanging construction trolley which comprises a rack, tires, a driving system, an executing mechanism, an arrangement mechanism and a master control console. The tires are rotatably installed at the bottom of the rack, the master control console is installed on the rack, the driving system comprises a driving motor and an oil pump, the executing mechanism comprises a rocker arm spindle, a first telescopic rod, a second telescopic rod, a pushing beam and a pushing rod, the driving motor drives the rocker arm spindle, the first telescopic rod is installed at the first end of the rocker arm spindle, the second telescopic rod is installed at the second end of the rocker arm spindle, one end of the pushing beam is connected with the first telescopic rod, the other end of the pushing beam is connected with the second telescopic rod, the pushing rod is installed on the pushing beam. The arrangement mechanism comprises an arrangement beam, wherein one end of the arrangement beam is fixedly installed on the first telescopic rod, and the other end of the arrangement beam is fixedly installed on the second telescopic rod. The flatness and looseness during laying and hanging of a preliminary-stage supporting surface isolation layer of a tunnel are guaranteed, and the problems of lining void and the like caused by swelling of waterproof plates at a later construction stage are avoided.

Description

technical field [0001] The invention relates to the technical field of engineering construction equipment, in particular to a construction trolley for automatic laying and hanging of waterproof materials for tunnels. Background technique [0002] At present, under the situation of rapid development of China's railway and highway construction, the construction quality and construction safety of tunnel engineering are particularly important. And the control of construction quality is the most important. In the existing construction technology, after the initial support of the tunnel, it is necessary to lay the geotextile first, and then lay the waterproof board. When laying, it is necessary to lay and hang the whole ring at one time. Generally, the laying platform adopts the simple operation of self-processing Platform, and the whole process is manually operated. Due to the heavy weight of the entire ring and volume of geotextiles and waterproof boards, the construction requi...

Problems solved by technology

In the existing construction technology, after the initial support of the tunnel, it is necessary to lay the geotextile first, and then lay the waterproof board. When laying, it is necessary to lay and hang the whole ring at one time. Generally, the laying platform adopts the simple operation of self-processing Platform, and the whole process is manually operated. Due to the heavy weight of the entire ring and volume of geotextiles and waterproof boards, the construction requires about 6 to 7 people to operate at the same time, and because the materials of geotextiles and waterproof boards are relatively hard, manual laying The flatness and slack during hanging are basically not guaranteed, and the uncertain factors of human operation are relatively large, which leaves a lot of hidden dangers in the construction quality in the later lining construction. The most obvious is the tearing of the waterproof board and the bulging of the waterproof board. problems such as lining voids
