Culvert rehabilitation can be defined as the process of extending the service life of a given culvert without removal of the existing culvert.
Three phases are considered in culvert rehabilitation. Phase one is stabilization of the culvert. In this first phase you cut out curled-in pieces of the old culvert by hand, then you assemble the liner plates inside the culvert, section by section which are later bolted together manually.
Creation of a smooth lining is the second phase put to task during the process of culvert rehabilitation. To get more info, click culvert rehabilitation. During the second phase of culvert rehabilitation, a smooth, watertight and sound pipe which is structurally sound within the new tunnel liner plates is created Smoothening of the corrugations made by flanges is also done.
Soil stabilization phase is the name given to the third stage of culvert rehabilitation. During the final stage of culvert rehabilitation, the extremely unstable soil surrounding the culvert is worked on; related problems are prevented from reoccurring to the rehabilitated culvert by stabilization of the surrounding soil with cementitious grout, which is injected until refusal.
To ensure the quality of the done culvert rehabilitation, normal inspection procedures should be applied.
Before hiring a given company one has to consider its history The history of a given company regarding the contract signed with its customers should not be ignored as it will give one a glimpse of the nature of the company he’s dealing with. A rehabilitation company with good history can be trusted to rehabilitate other culverts.
One should consider the kind of material used by the culvert rehabilitation company.
The a company whose materials used are of the rightful quality and standard should be recommended because incidences of the rehabilitated culvert malfunctioning or breaking down again easily are minimized.
The overall cost of rehabilitating the culvert should be put into consideration. Normally is nice to be economical since resources are scarce hence a company that offers to provide a cheaper cost of rehabilitating the culvert is given the priority as the cost of rehabilitating a culvert should not be similar to that of purchasing a new one.
Another measure to consider the kind of workmanship offered by the given rehabilitation company.To get more info, visit culvert rehabilitation company.
