Embodiment 1

[0023] Such as figure 1 Shown, a kind of construction technique of metal corrugated culvert comprises the following steps:

[0024] Step 1. Foundation trench excavation

[0025] 1) When there are design requirements, excavate the foundation trench according to the design requirements; when there is no design requirement, refer to the following table for the excavation width of the foundation trench and the thickness of the foundation foundation. In order to facilitate mechanical rolling, it is recommended to use the standard width of the foundation.

[0026]

[0027] 2) Excavation of the foundation trench shall be carried out in accordance with the requirements. When the base soil is bad soil layer such as silt, it shall be replaced and over-excavated shall be avoided as far as possible. Submit to supervision and design unit for approval.

[0028] 3) The soil foundation pit dug to the elevation shall not be exposed, disturbed or soaked for a long time, and the size, eleva...

Abstract

The invention discloses a construction process of metallic corrugated culvert pipes. The construction process comprises the steps of foundation trench excavation, construction layout, foundation pad filling, pipe body installation, asphalt corrosion protection, culvert pipe earthwork backfilling, tunnel opening paving, slope protection and the like. The construction process disclosed by the invention has the advantages of high field installation speed, short construction period and high efficiency and is favorable for reducing the construction cost; furthermore, the later maintenance workloadis small, and the maintenance cost is low; pipe fittings are connected by adopting pipe hoops, are free of welding, pollution as well as waste gas and sewage discharge, and belong to green and environment-friendly products; and the use of conventional building materials such as cement, sand and stone is reduced, so that the construction process has profound environmental protection significance.

Description

technical field [0001] The invention relates to a construction technology of culvert pipes, in particular to a construction technology of metal corrugated culvert pipes, and belongs to the field of construction technology of culvert pipes. Background technique [0002] Culverts are one of the important components of highway engineering. Most of the current small bridges and culverts are reinforced concrete structures. Most of these structures have various degrees of damage during use, and their adaptability to geology is poor, especially in soft soils. , Permafrost regions, the disease is particularly serious. The metal corrugated culvert structure has good adaptability to deformation and excellent mechanical properties. The culvert using flexible and high-strength steel corrugated pipe not only has good ability to adapt to the deformation of the foundation and foundation, but also can solve the problems caused by uneven settlement of the foundation. The problem of culvert ...
