This video shows a custom conveyor built for a 99-inch diameter tunneling shield equipped with "sand-shields" and an excavator. An "apron" is utilized to direct the spoil into the conveyor where it is lifted and dumped into a muck cart for removal from the liner plate tunnel.

Corrugated metal pipe (CMP) was introduced for culvert applications. Culvert installations are failing at an alarming rate and may cause untold damage. This paper discusses options for a failing culvert including the complete replacement with the same or larger size pipe.

With today’s economic realities, it is more important than ever to closely scrutinize culvert failures and develop long term, cost effective, site appropriate, solutions. To do this it is necessary to consider the fundamental modes of culvert failure and possible solution options from a geotechnical perspective.

This paper discusses why there is an increasing interest in rebuilding infrastructure and preventing catastrophic culvert failures. It is essential to realize that any attempts to rebuild or repair culverts must address the composite structure that exists within the soil and pipe environment.

Eastern States Construction, in Wilmington, DE was called upon to keep the traffic flowing while a failing culvert line was replaced. The work was completed quickly with very little inconvenience to the traveling public. This paper tells how they did it with Tenbusch Tunneling Equipment.

Author discuss cost of culvert failure both qualitatively and quantitatively. Presents results of literature survey on the subject. Very informative.

As America’s infrastructure ages, the risk of failures increases. The purpose of this paper is to: quantify the economic implications of culvert failures including related user delay costs; find out if the risk of failures is being considered as a selection criteria; and, identify the need to document failures.

Authors discuss several recent culvert and drainage systems failures and estimate the cost saving for similar projects when a longer life pipe like Pre-Cast Pipe is used.

This document provides information to infrastructure owners about the options they have to best utilize Reinforced Concrete Pipe (RCP) and Pre-Cast Boxes to address current and pending failures, or undersized storm drains in their existing systems.

This is a pdf of a power point presentation which gives an overview of tunneling applications typical of medium to large diameter utilites (i.e., water and sewer). The overall tunnel processes and equipment is discussed for typical applications utilizing Tenbusch tunneling equipment.

Brief overview of hand mining process using a tunnel shield. The overall process is presented for a typical liner plate tunneling application.

This paper is meant as a guide in understanding lubricant products and their use. It is written from a very practicle viewpoint.

Article from Underground Construction Magazine - discusses challenges of sliplining medium to large diameter pipe.

Article from Tunnel Business Magazine about the 150-ton DD12-150 Tenbusch Sliplining Machine.

Article from Tunnel Business Magazine about the Tenbusch tunnel boring machine manufactured with a removable hydraulic power unit (HPU).

This article discusses a complex tunneling project which required the installation sewer force mains. It was challenging because of the existing wet ground conditions, proximity of the sewer line to buried utilities and inconsistent fill, the need to tunnel under a levy located next to the Mississippi River and into the cofferdam in the river.

Tunnels and Tunneling article describes the two main methods of hand mining and essential considerations.
