Site Investigation & Thrust Bore Planning
All services listed below are available through Chiltern Thrust Bore upon request. Please contact us for more information.
Topographical Surveying
Topographical surveying is an important preparation tool to ensure an accurate trenchless installation. Topographical surveys allow us to calculate and maintain crucial clearances to existing ground levels in order to protect infrastructure and the environment. Whilst also providing detailed information essential for understanding the complexity of individual crossings and the equipment needed for each project.
Site Investigation
Geotechnical Investigation works, also known as Soil sampling is a crucial aspect of any construction project.
Ground conditions are a significant source of risk to all construction projects; this is particularly pertinent when assessing the feasibility and the planning of a thrust bore.
Working closely in conjunction with an independent geotechnical and environmental consultancy, we can identify geotechnical engineering hazards and subsequently find the solutions to minimise installation risks.
With a full and comprehensive understanding of the ground conditions on a particular site, Chiltern Thrust Bore Ltd's technical team are able to assess feasibility and select the equipment/methodology best suited to complete the installation(s).
Feasibility studies
Utilising our Horizontal directional drilling machines, we are able to test the suitability of specific areas for future tunnelling / other trenchless methodology projects.
Using the HDD’s traceable drilling head, we can accurately prove pre-determined paths up to 400m to ensure there are no unforeseen obstructions along the proposed route.
Our drilling equipment can also be used for testing the cohesiveness and strength of the ground conditions along a set line, level and gradient.
Using this methodology could prevent unnecessary expenditure as a result of unforeseen obstructions or adverse ground conditions.
Atlas Bore Planner®
The Atlas Bore Planner® software system allows our engineers to plan and visualise a bore path before drilling.
A detailed terrain plan is entered into the software either manually, or by using a system of lasers where the engineer in the field walks the approximate path of the bore. The Software then analyses the information received from the sensors and converts it into a terrain plan.
Utilities and other underground services, rivers, lakes, roads, railways etc, are all added to the bore plan, and the engineer is able to specify the exclusion zone around these utilities.
When the software has all the information it needs, it calculates the bore path. The software will not allow the exclusion zones around underground services to be entered, nor will it allow the bend radius of the rods to be exceeded.
When the planning stage is complete, the bore plan and drilling details can be printed. These include detailed instructions including the precise angle of each rod.
