CASE STUDY: M56 Blocked Culvert Clean

 

M56_motorway_sign_Junction_14

We’ve been doing incredible work on the M56! MEGATRON, our brilliant industry leading vacuum tanker, was on site to clear a 1000mm blocked culvert! The trash screen that was present was severely damaged and was removed for us to access the huge culvert. It ran underneath the M56, 6 lanes + hard shoulders through to a farmer’s field. The huge tunnel was approximately 8m off the M56 carriageway. This was no access issue for Megatron’s powerful suction and Hydro Cleansing’s hose. We used a cofferdam to halt the flow of water and allow the confined space team to access the blocked culvert.

6000 gallon bulk tanker removed the waste. Our fantastic confined space engineers cleared the huge culvert with extraordinary efficiency! You can’t beat our engineers for hard work and passion!

Over the past few years the silt had built up and blocked the inlet of the culvert this in turn meant that whenever it rained, it flooded the surrounding area/fields on the west bound carriageway. Hydro Cleansing cleared all the slit and debris from the blocked culvert and tipped slurry off site. The culvert is now free from debris and the stream free flowing. A new trash screen was installed.

JOB DONE!

Megatron and HCL Clear Hundreds of Tonnes of Silt

236 tonnes of waste was cleared by Megatron and team.

As well as our beast Megatron, Jack the Giant Slayer, a second articulated bulk tanker, a standard bulk tanker, the 2 man confined space team, a jet vac tanker and a welfare unit all worked on the large job.

A large water filled Cofferdam was put in place to stop the river water from flowing through the culvert. We supplied the cofferdam for free. There is a baffle within the dam creating 2 chambers which maintain its stability.

This unsightly black bag makes minimal impact on the environment. It uses the properties of water to hold back the river water. It is simply emptied and removed when the job is complete.

The river which runs through the culvert, under the A13, supports the RSPB Reserve at Rainham Marshes. Having been an MOD firing range for several decades it was converted into the nature reserve in 2000. The area is only 6ft above sea level and could easily flood, endangering the birds.

With the dam in place, the confined space team beavered away clearing the monumental amount of waste into Megatron’s vacuum.

The bulks were filled alternately and took the waste away for disposal, allowing the beast to work continuously.

Job done

 

Sucking at 6000+ cubic feet per minute, Megatron is Europe’s leading vacuum tanker. This raw power from the tankers and engineers allowed this job to be completed in five days!
