Rectangular aqueduct construction steel mould trolley

Abstract

A rectangular aqueduct construction steel mould trolley is composed of an inner trolley and an outer trolley; the inner trolley is composed of an inner trolley track (1), an inner trolley chassis (2),and a plurality of inner trolley template structure units composed of inner trolley portal frames (3), inner trolley templates and inner template lifting devices; the outer trolley is composed of anouter trolley track (17), and a plurality of outer trolley template structure units composed of outer trolley portal frames (18), outer trolley templates and outer trolley template lifting devices; the both sides of the outer trolley portal frames (18) are provided with three layers of construction platforms separately; inner and outer trolley traction devices are provided with a hoist separately.After the wall of an aqueduct and flange plates are cast to reach a certain strength, the inner and outer trolley templates are removed, and then the steel mould trolley can move forward to a next station under the traction of a hoist, so that hoisting equipment and manual handling are not required; the construction efficiency is increased by three times or so, and labor force is saved greatly; and revolving materials are saved, and the appearance quality is improved.

Description

technical field [0001] The invention relates to equipment for water conservancy construction, in particular to a steel mold trolley for the construction of rectangular aqueduct walls and flange plates, which is suitable for use in large and medium-sized rectangular aqueducts. Background technique [0002] At present, there are usually two types of large-scale aqueduct formwork solutions: on-site assembly and customized aqueduct making machines. The template scheme for the Caohe aqueduct of the main line of the South-to-North Water Diversion Project belongs to the former, and the template scheme for the Tuanhe aqueduct belongs to the latter. [0003] The Caohe aqueduct of the middle line of the South-to-North Water Diversion Project is a three-way prestressed cast-in-situ overhead aqueduct. The external structure size of the aqueduct body is 29.96×22×7.9m, the single-span flow section is 6×5.4m, and the single-span aqueduct body has an unloaded weight of about 3500t. Two sto...

Problems solved by technology

The one-time investment of this scheme is high, the equipment manufacturing cycle is long, the transportation, installation and disassembly costs are high, and it is only used for this project, and the construction cost is high

[0005] At present, the formwork scheme of medium-sized aqueducts basically uses combined steel formwork to assemble on site. Some projects use large formwork, which is installed and disassembled by cranes, and manually installed. Each section needs scaffolding. Traditional formwork requires a lot of turnover materials.

Both types of schemes use relatively dense tension bolts to strengthen the formwork. After the pouring is completed, the tension bolts need to be processed, which consumes manpower and material resources and affects the appearance quality

The construction efficiency of these two types of schemes is low and the cost is high
