LLC "Southern Power Engineering Plant"

Horizontal directional drilling
from 100 meters

Modern technology for laying engineering utilities beneath the ground surface using the trenchless construction method

Cost of works

The price is formed individually for the site, but in most cases HDD is 2–2.5 times more cost-effective than the trench method.

Savings up to 2–2.5x

Less than an hour up to -40% on the performance of works

Less equipment without unnecessary earthworks

Lower costs without restoring large sections

Calculation for your facility

The final cost depends on the parameters of the route, the pipes, and the site conditions.

Special cooperation terms are possible for regular customers.

Advantages of the solution

Advantages of HDD technology

Tight deadlines for the completion of works

Preparatory works, relocation and deployment of the drilling complex take a day, and the pipeline laying rate is: up to 200 linear m/day with a pipeline diameter up to 400 mm; 100 linear m/day with a pipeline diameter from 400 to 750 mm. This significantly reduces the use of associated processes.

Minimum areas for equipment placement

To carry out work on any section of pipeline of various lengths and diameters, only two 3×8 m technological sites are required. Their placement can be flexibly adjusted, which is very advantageous in urban conditions, makes it possible to find solutions for the most complex tasks, and also significantly reduces the time and costs of obtaining permitting documentation.

Pipeline installation on terrain with a high groundwater level

HDD provides the possibility of laying pipelines at a high groundwater level without compromising the quality of the installed networks. The method does not exclude the use of dewatering services, but reduces their use to two points at the beginning and at the end of the pipeline route, and also shortens their operating time to several days.

Pipeline burial depth up to 12 m

Modern locating equipment makes it possible to lay a pipeline without changing deadlines and quality at depths of up to 12 m. For the open method of work, this process is impossible.

Preservation of the natural landscape and ecological balance

Often, the construction of engineering systems requires significant destruction, which leads to the loss of the natural landscape and ecological balance. HDD makes it possible to carry out all work while preserving the area, minimizes restoration work and, as a result, saves the project budget.

Absence of a traffic stop for any types of transport

Most often, it is necessary to lay utilities in areas with developed infrastructure where there is heavy traffic: intersections, highways, railway lines. The HDD technology makes it possible to carry out all work without stopping the movement of any type of transport and is an environmentally friendly method.

Reduction of financial expenses

The HDD method makes it possible to save a large portion of funds when constructing new or replacing old underground utilities.

Solution options

Choose according to your needs

Under functioning buildings and structures

We perform horizontal drilling without stopping the facility’s operation and without damaging the existing infrastructure.

Under the routes of highways

We lay utilities under roads without excavating the pavement and without blocking traffic.

Under water bodies (of natural and artificial origin)

We implement crossings under rivers, lakes, and artificial reservoirs with minimal environmental impact.

Under the branches of the railways

We carry out work under railway tracks without interfering with the train schedule and without opening up the track bed.

In areas with complex / heterogeneous terrain

We work in areas with complex geometry, elevation changes, and non-standard soil conditions.

In areas with enhanced amenities

We make it possible to preserve the landscape, surface cover, landscaping, and site improvement elements without large-scale earthworks.

In private areas and in territories protected by law

We carry out work taking into account access restrictions, safety requirements, and applicable regulations for special areas.

Work process

Drilling stages

1. Planning and calculation of the drilling trajectory

Includes a survey of the area where the well drilling is planned. The locations of existing utilities and obstacles are studied, and the places where the pits will be located are selected — the entry and exit holes.
At this stage, the pipeline is delivered and assembled into a ready bundle of the required length.

2. Drilling a pilot borehole

A drilling head with a cutting blade, containing a probe-transmitter, is inserted into the ground in the specified direction. The drilling rig gradually drills in the rods, building up the drill string.

Its movement is continuously monitored. The probe transmits accurate information about the drill’s position in plan, its inclination, and drilling depth to the receiver of the locating system. Thus, the string moves strictly along the intended direction, setting the trajectory of the future utility line.

3. Pre-reaming

This type of work consists of enlarging the diameter of the obtained hole for the further unobstructed pulling of utilities. Instead of the drilling head, reamer-expanders of various diameters and designs are used as attachments.

Depending on the soil type: kodiak, compact, cutting blade, cutting-compacting, roller cone, roller and other types of reamers. The number of reaming passes in different situations depends on the soil type, the length of the bore, and the parameters of the drilling machine.

In any case, the borehole diameter must be 20-30% larger than the pipeline diameter.

4. Pipeline pullback

At the final stage of pipe installation using the HDD method, a pullback is performed of pre-welded pipeline strings attached to the drill string via a swivel.

This is a special device that does not transmit the rotational movements of the drill string to the pipeline string. After sealing the holes and cleaning up the construction site, the facility is handed over to the customer together with the as-built documentation.
