Embodiment Construction

[0029] See Figure 1- Figure 6 , large-scale concrete arch culvert construction, due to the large construction warehouse surface, high concrete pouring volume, wide contact surface with air (20×25m), the construction is difficult, especially in high temperature seasons, the concrete surface in the warehouse evaporates and slumps The loss of strength is faster, the "aging" of concrete is accelerated, and early hardening, cold joints, and poor bonding between layers are prone to occur. In order to meet the needs of on-site pouring, the present invention adopts an integrated new construction technology to solve the problem. The specific design is: (1) Choose the best raw material suppliers to ensure the smooth supply of arch and culvert construction logistics. Through automatic feeding of warehouse aggregates and ground ridges, various raw materials are sent to the mixing building. (2) Automatic feeding, automatic weighing, concrete production and system controlled by computer, ...

Abstract

The invention relates to a device of integrated continuous constructing the large concrete project, belonging to the aqueduct, bridge, culver and other concrete projects. It mainly comprises the devices for measuring, feeding and mixing the concrete raw material, wherein, the concrete mixing device is connected to the main driver via the concrete transition feeding device while the feeding belt of main driver has several material-transfer outlets; the material-transfer outlet is connected to the concrete feeding device on the walking lifting distributing and feeding device; and the concrete feeding device comprises several outlets. The invention has following characters: (1) it can realize integrated continuous construction system; (2) it can increase the irrigation speed of concrete project to confirm the construction strength and quality; (3) the distribution of said device is reasonable and tight; (4) it can improve the working efficiency, reduce the cost and shorten the construction period. The invention can be used in artificial aqueduct, bridge, culver and other concrete projects.

Description

technical field [0001] The invention relates to the technical field of artificial waterways, bridges, culverts and concrete engineering construction methods and equipment, in particular to an integrated continuous construction device for large-scale concrete engineering. Background technique [0002] Concrete projects such as large arches and culverts have the characteristics of large steel bars and formwork projects, large storage areas, and large amounts of concrete, and require high quality. In order to ensure the quality of the project, in addition to the stable quality of concrete production, the continuity of concrete in production, transportation, supply, warehousing and distribution is also required. At present, the construction level of similar projects can be roughly divided into three situations: average, better and best: (1) In the construction of similar projects in general, labor and a small amount of machinery are mostly used for concrete production, transport...
