Embodiment Construction

[0015] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0016] Measurement stakeout

[0017] Level the construction site, accurately stake out and measure the plane position and excavation depth of the culvert,

[0018] Excavation

[0019] The excavation of the foundation pit adopts mechanical excavation. If the groundwater is rich after the excavation of the foundation pit, a sump is dug outside the hole body of the excavation foundation pit, and the longitudinal excavation section along both sides of the foundation pit is 30×30cm The drainage ditch allows water to flow to the sump, and the water pump is set to pump and drain the groundwater in the foundation pit to the outside of the roadbed in time. After the excavation of the foundation pit is completed, the foundation bearing capacity test shall be carried out on the culvert base in time, and the bearing...

Abstract

The invention relates to a construction method, in particular to a steel corrugated pipe culvert construction method which comprises the following steps of excavation of a foundation pit, pouring of foundation concrete, assembly of corrugated pipe couplings, offset correction of the pipe couplings, and joint treatment of the pipe couplings. The assembly of corrugated pipe couplings is that in installation, middle pipe couplings are installed, positions of a water inlet and a water outlet are reserved, and the water inlet and the water outlet on two sides are installed after the middle pipe couplings are installed completely and corrected in place. By means of the steel corrugated pipe culvert construction method, the structure is firm, the construction is fast, and leakage is avoided. Practice has proved that when highway adopts a steel corrugated pipe culvert structure instead of other pipe culverts, the construction period is shortened, the manufacture cost is reduced, load-carrying capability of the structure is reasonable, load distribution is uniform, and the steel corrugated pipe culvert structure has a certain deformation resistance; slab staggering at the junction of a soft soil foundation structure and an embankment is avoided to some extent, comfort and safety of vehicle running are improved, and service and maintenance cost after construction is reduced.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method of a steel corrugated pipe culvert. Background technique [0002] The steel corrugated pipe culvert structure has the advantages of safety, reliability, economy, technological innovation, convenient and fast construction, and ecological environmental protection. It has achieved good economic and social benefits during construction. However, the construction of traditional corrugated pipe culverts is time-consuming and often occurs. The phenomenon of leakage, and the traditional construction technology and the original foundation are easy to dislocate. Contents of the invention [0003] The purpose of the invention: to provide a steel corrugated pipe culvert construction method with fast structure, fast construction and no leakage. [0004] In order to achieve the above object, the present invention takes the following technical solutions: [0005] A steel corruga...
