Cast-in-place cover slab culvert formwork system and construction method of application of cast-in-place cover slab culvert formwork system

Abstract

The invention provides a cast-in-place slab culvert template system and a construction method applying the same. The construction method is the construction method applying the cast-in-place slab culvert template system. The construction method comprises the following steps: staking out in survey; excavation of foundation pit; construction of a basic template and concrete pouring; construction ofa slab culvert abutment template and concrete pouring; integral pouring construction of an abutment cap and an abutment body; hoisting and building of a cover plate; construction of a splay-wall template and concrete pouring; and construction of a waterproof layer and backfill. The cast-in-place slab culvert template system comprises a cast-in-place slab culvert abutment body template system, a slab culvert cast-in-place splay-wall template system, a slab culvert cast-in-place basic template system and a slab culvert cast-in-place abutment cap template system. According to the cast-in-place slab culvert template system and the construction method applying the same, based on an existing slip-form construction technology, a set of relatively perfect construction method of the cast-in-place slab culvert template system is formed from the aspects of deepened design, hoisting, template detail node treatment, process key points and the like of an assembled member.

Description

technical field [0001] The invention relates to the field of highway engineering, in particular to a cast-in-place cover culvert formwork system and a construction method using the cast-in-place cover culvert formwork system, which is suitable for the construction of a cast-in-place cover culvert platform, especially for large-section cast-in-place covers Slipform construction of slab culvert body. Background technique [0002] The sliding form method appeared at the beginning of the 20th century. In the 1940s, the sliding form method has been widely used abroad, and the construction technology has also been improved. my country introduced the sliding form method in the 1930s and popularized and applied it in the 1970s; at present, the sliding form technology in my country has been relatively perfect and has been successfully promoted and used in the construction of culvert side walls. The construction technology of the side wall of the culvert can be improved. [0003] How...

Problems solved by technology

[0003] However, the existing sliding form technology is somewhat insufficient in local treatment. For example, during the demoulding process of the tall and large formwork, it is difficult to control due to the large formwork, which is easy to cause damage to the completed concrete surface of the platform body; During the pouring process of the slab culvert platform, the synchronization of concrete pouring on both sides of the platform and the vibrating operation are also a major problem. Furthermore, the transfer efficiency of the sliding form system is also insufficient when pouring in sections
