By pushing through pipeline lines, it is possible to carry out construction procedures for laying steel casing, concrete and fiberglass pipes. A special property of the technology is manifested in the fact that sagging of the pipe, deviations of objects from a given direction are excluded, energy consumption is also observed at a low level, fast penetration is ensured.
The pipes are forced through by pressing the pipe elements into the soil mass with open ends, using hydraulic jacks. The soil mass trapped inside must be developed, after which it is extracted by mechanical or manual methods.
Stages of the work:
A) A reinforced excavation is being developed, and the thrust walls for the jacks are being poured.
B) The necessary equipment is installed in the excavation.
C) The pipes are pressed in with a jack, alternately switching to forward and reverse motion.
D) The development of the soil core is carried out and brought to the surface.
Trenchless steel pipe penetration methods will help protect engineering networks from negative environmental influences, as well as from corrosion and destruction. The technique guarantees the safety and integrity of pipes under any difficult operating conditions.
Laying of metal structures by trenchless construction methods
The laying of steel cases by pressing into the ground can be considered a preferred type of trenchless pipeline construction. This technique is used especially when it is necessary to create additional pipeline protection from external negative influences. Such a factor can be considered high humidity and the proximity of other engineering and communication lines, which have a bad effect on the overall condition of the pipeline surface by their presence.
The method of piercing steel casings is used during the organization of a gravity sewer (drainage) system. During the installation of thermal communication systems, electrical wires, telecommunications wires and other types of cables under railways or highways, under runways, the use of the method is considered more effective. Pipe penetration, without developing the ground rock using puncture methods, should be applied to the area where the product of preliminary geological and geodetic analysis gave a positive result on the existence of a planar and other soft rocks of the earth.
Pushing metal casings into the ground is used for trenchless laying of pipe weaves, the diameter of which reaches up to 2010 mm, with an intermediate distance of 75 m, when roads are being built along the pipeline path or a railway track is discovered. If it becomes necessary to carry out work at distances up to 110 m, in such a situation it is allowed to lay pipes only on soft-looking ground rock or using an additional class of special power construction aggregates.
Trenchless pipe laying methods, in addition to the noted high versatility, have a number of other advantages. The special equipment used to push through the steel case has a small size and low specific gravity. The size of the special construction equipment allows the units to move quickly along the trajectory, they can be easily mounted in a narrow space. Also, there is no need to carry out additional preparatory work for the construction of the starting working well. Any natural depression or trench can serve as a working excavation.
Pressing through the steel case will help to eliminate almost all possible emergency situations, during the process itself and during further pipeline operations.
