Trenchless technologies DINRUS ASR-20, 60, 240, MNB-50, 125, etc.

These are modern, easy-to-operate and very reliable installations for trenchless laying and renovation of pipelines with diameters from 63 mm to 1440 mm. The proposed trenchless laying technology installations operate in more than 40 regions of Russia.

The installation for trenchless laying of pipelines ASR-20 allows you to replace pipelines without opening the ground and lay new ones made of various materials (with or without destruction of them) with a length of up to 300 m, depending on the soil, maintaining the inner diameter or increasing it by 1.5 times. Lay steel collectors under railways and highways. Conduct work on the rehabilitation of pipelines located between standard wells. The ASR-20 installation can be located in a well with a diameter of 1000 mm. Special base plates are used for this purpose.

• ASR-20. Technical specifications.

Installation for trenchless laying of pipelines ASR-60 allows you to conduct pipelines without resorting to laying trenches. This method of underground laying is necessary when the pipeline crosses highways and trunk roads, as well as if there is a risk of damaging existing underground utilities. The ASR-60 technology involves the creation of punctures in the ground, which allows you to insert the pipe in a given direction.

• ASR-60. Technical specifications.

The installation for trenchless laying of pipelines ASR-240 allows you to replace pipelines without opening the ground and lay new ones made of various materials (with or without destruction of them) with a length of up to 120 m, depending on the soil, maintaining the inner diameter or increasing it by 1.5 times. To lay steel collectors under railways and highways. The ASR-240 installation is designed to work from the pit.

• ASR-240. Technical specifications.

Installation for trenchless laying of pipelines AST-250. The work of the installation is to create a pushing force of up to 250t for horizontal crushing of pipes into the ground. The hydraulic unit (hydroelectric power station) must be installed on a flat horizontal base at a distance from the power unit within the length of the connecting hoses. If necessary, the AST-250 installation can be converted from pushing to pulling for trenchless pipe laying. To do this, horizontal guide corners are installed on the inner side of the sidewalls, both the power frame and the support frame.

• AST-250. Technical specifications.

Using the MNB-50 directional drilling rig, it is possible to produce a trajectory-controlled and fully controlled puncture in plan and profile. Replace old worn-out pipes. Lay a new pipeline in the old worn-out collector. Replace or lay new sewer outlets from buildings into process wells.

• MNB-50. Technical specifications.

Installation of directional drilling MNB-125 - replacement of worn-out pipelines with new ones while maintaining or increasing their diameter and throughput. Replacement of worn-out pipelines with a decrease in their diameter without excavation. The device of crossings under highways and other obstacles.

• MNB-125. Technical specifications.

The UNB-30 directional drilling rig can be equipped with a rotary frame that allows you to turn the rig 360 degrees and drill from one point, which can be used when carrying out work on strengthening the soil or installing heat-bearing channels.

• UNB-30. Technical specifications.
