Embodiment Construction

[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific embodiments and accompanying drawings, but the following embodiments are only preferred embodiments of the present invention, not all . Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present invention.

[0031] The laterally supported pile-slab soilless subgrade of expressway is generally suitable for reconstruction and expansion projects with a span and filling height of 5-8m. It is composed of several prefabricated segmental slabs 1; Rib 8, prefabricated segmental slab 1 width 11.8m, slab thickness 0.24m, rib height 0.44m, rib bottom width 0.7m, rib center distance 6m, uniform size; prefabricated segmental slab 1 is divided into ...

Abstract

The laterally supported pile-slab soilless roadbed of expressway involves the new technology field of expressway construction. It consists of piles, pile-slab connection devices and end cap beams. The beneficial technical effects of the present invention are: a brand-new laterally supported pile-slab frame system is created, which can effectively transmit the upper vertical and horizontal loads caused by automobiles, etc., and the unique connection device of the pile-slab makes the pile and the slab not fully consolidated , have strong adaptability to temperature changes. Because there is no need to fill the piles, the land is saved, the impact on the surrounding environment is reduced, and it is beneficial to the protection of the environment. Pile and slab components are standardized and prefabricated in the factory and transported to the site. The degree of matching construction is high, showing the characteristics of short construction period and good economy. The innovative achievements of the invention will be in the leading position in China.

Description

technical field [0001] The invention relates to the new technology field of expressway construction, in particular to a laterally supported pile-slab soilless roadbed. Background technique [0002] In recent years, with the rapid development of my country's economy, the traffic volume has also increased rapidly. The expressways built in the early stage have experienced serious traffic congestion problems, which have affected the service level and traffic capacity of the roads. Large-scale expressway reconstruction and expansion are imminent. Many original roads can no longer meet the existing needs, so many domestic roads are facing the need for widening. In the past road widening, the roadbed of the widening part is often used to fill the roadbed. While the traditional highway reconstruction and expansion method has gained rich practical experience, it also has many shortcomings: ①Difficult land acquisition and large amount of filling; ②Complicated construction, long perio...
