Embodiment Construction

[0027] The present invention will be described in detail below in combination with specific embodiments.

[0028] The invention relates to an assembled corrugated culvert foundation for preventing partial settlement, which has the characteristics of preventing partial settlement, reliable connection, strong versatility, convenient construction and the like, and is suitable for corrugated culvert and similar corrugated culvert structures.

[0029] According to the actual length of the corrugated culvert, the foundation is composed of a plurality of foundation blocks 1 assembled, one end of the foundation block 1 is provided with a groove 6 , and the other end is provided with a boss 7 matching with the groove 6 . In the direction of the longitudinal axis of the corrugated culvert, the adjacent foundation blocks 1 are arranged in occlusion through the mutual positioning of the grooves 6 and the bosses 7 . The shape of the groove 6 and the boss 7 is a cube, a cuboid or a cylinder...

Abstract

The invention relates to a spliced type corrugated plate culvert foundation capable of preventing local settlement. The corrugated plate culvert foundation is poured on site commonly, is high in construction difficulty and is low in adaptability to unequal settlement of a subgrade. The spliced type corrugated plate culvert foundation is formed by splicing a plurality of basic blocks, a groove is formed in one end of each basic block, and a boss matched with the corresponding groove is arranged at the other end of each basic block. The adjacent basic blocks are arranged in an engaged mode through mutual positioning of the grooves and the bosses in the longitudinal axis direction of a corrugated plate culvert. Reserved holes for penetrating of a cable are formed in the lower half portions of the basic blocks in the longitudinal axis direction of the corrugated plate culvert. After the multiple basic blocks are spliced into the foundation, the cable penetrates through the reserved holes throughout in the longitudinal axis direction of the corrugated plate culvert, and the two ends of the cable are provided with outer threads and fixed through base plates and connecting nuts. The spliced type corrugated plate culvert foundation can effectively prevent local settlement and longitudinal and transverse displacement of the foundation, is reliable in connection and high in universality due to positioning splicing of the grooves and the bosses, and realizes rapid construction of the plate culvert foundation.

Description

technical field [0001] The invention belongs to the technical field of traffic construction, and in particular relates to an assembled corrugated plate culvert foundation for preventing local subsidence. Background technique [0002] Corrugated steel structure is a new structure and new technology that replaces conventional bridge and culvert structures in my country's highway industry in recent years. Due to its strong applicability, simple construction process, saving construction period, standardized production, low-carbon environmental protection and other advantages, it has been used in Inner Mongolia, Qinghai, Xinjiang, Tibet, Shaanxi, Shanxi, Anhui, Guangdong, Guangxi, Hunan, Hubei, Yunnan and many other regions have been popularized and used, and the use function and durability can completely replace conventional structures. [0003] my country's "Design Rules for Highway Culverts" (JTG / T D65-04-2007) clearly states that steel corrugated slab culverts are suitable for...
