Background technique

In recent years, with the rapid development of my country's economic construction, in the process of highway construction, it is necessary to pay full attention to the protection of roadbed slopes, which is conducive to improving the overall stability of the roadbed. It is an indispensable part of highway construction to formulate perfect roadbed slope protection measures, and roadbed slope drainage is a crucial measure for roadbed slope protection.

The following schemes are usually considered for slope drainage during subgrade construction: 1. Some construction units will directly open grooves on the slope for drainage in consideration of economic cost. Standardized construction site construction requirements, even lead to direct damage to the slope; Second, some units will pour a layer of concrete in the side ditch or use mortar masonry, but because the roadbed construction process needs to brush the slope at the end, so Drainage ditches that lead to expensive construction need to be broken, resulting in waste of resources. 3. There are also units considering the use of prefabricated drainage ditches, but usually prefabricated drainage ditches require high economic costs, and a large amount of labor is required for installation during the construction process, and mechanical assistance is required during the installation process. There are still certain risks in the construction process of high slopes Sexuality, and the later demolition is also more troublesome, it is difficult to be promoted.

To sum up, in the process of infrastructure construction, there is an urgent need for a drainage device for subgrade slopes with low economic investment, easy installation and stable drainage effect.

Detailed ways

The technical scheme of the utility model will be described in detail below with the accompanying drawings, but the protection scope of the utility model is not limited to the described embodiments.

Example 1: During the construction of the roadbed, the number of drainage ditches is designed according to the slope of the roadbed side slope and the local rainfall, and then a 50*50*50cm trench is excavated on the roadbed side slope.

The utility model subgrade slope assembly type drainage device is composed of several installation sections 2 connected to form a prefabricated drainage ditch 1; the installation sections are integrally pressed by iron sheets with a thickness of not less than 1mm. The installation section 2 is a water tank structure composed of at least two vertical surfaces 3 and a bottom surface 4, and the top of the two vertical surfaces 3 is provided with an everted skirt 5; The lengths of the three sides of the section are 50cm, 50cm and 50cm respectively; the width of the skirt is 25cm. The skirt 5 is provided with a fixing hole 8, and is fixedly connected to the ground through an iron drill passing through the fixing hole 8. A reinforcing beam 9 is also arranged between the two vertical surfaces of the installation segment.
