Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right" etc. is based on the orientation or positional relationship shown in the drawings, and is only for It is convenient to describe the present invention and simplify the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as limiting the present invention.

[0045] A construction method for soft soil subgrades on both sides of highway bridges and culverts, comprising the following steps:

[0046] S1, position design, measure the basic parameters such as water content and softness of the soft soil base, then draw a drawing according to ...

Abstract

The invention discloses a construction method for soft soil subgrades on both sides of highway bridges and culverts. Drill drainage holes at the corresponding positions of the subgrade, and then reinforce the side walls of the drainage holes with permeable concrete; S3, piling, driving wooden piles into the corresponding positions of the soft soil subgrade; S4, drainage, removing the accumulated water in the drainage holes Drain; S5, filler, bury coarse sand or stones in the drainage hole. Pile driving can squeeze the soft soil roadbed, which can not only compact the soft soil roadbed, but also squeeze the water in the soft soil roadbed into the drainage holes, thereby reducing the water content and voids in the soft soil roadbed, and then drain the water from the Drainage holes can be drained. In this way, the soft soil subgrade can be effectively improved. At the same time, the drainage holes and wooden piles can also play a supporting role in the later stage. The combination of the two can effectively improve the use of roads on soft soil subgrades. life.

Description

technical field [0001] The invention relates to the technical field of soft soil roadbed construction, in particular to a construction method for soft soil roadbeds on both sides of highway bridges and culverts. Background technique [0002] Due to the rapid development of my country's market economy, the development of tourism is also getting faster and faster, which has gradually increased the number of road and bridge construction projects in our country, and to build more qualified road and bridge buildings, to a large extent It is necessary to do a good job in the construction and technical treatment of the soft soil foundation. [0003] Because of the weakness of the soft soil foundation, the general soft soil foundation is not suitable for the bearing layer. In order to lay the foundation for the formation of the foundation, it is necessary to do certain treatment on the soft soil foundation. Because of its high water content, large pores, high compressibility and low...
