Building method for pipeline including minitunnel

FIELD: building, namely underground structure erection, particularly for building multipurpose pipelines under acting roads without traffic interruption and in difficult mining and geological conditions and in presence of watered tunnel base ground.

SUBSTANCE: method involves forming minitunnel by successive driving hollow reinforced concrete sections in ground and/or embankment along with simultaneous supplying thixotropic mix; connecting above sections one to another and to neighboring pipeline sections during driving thereof. Pipeline sections have opened end parts. One end part has annular grove opened from section end for receiving metal shell extending out of the section end and having thickness of not more than groove depth. Shell and end section part form stepped funnel. The second section end part tapers in stepwise manner to end thereof to form bush part having one step for shell of neighboring section receiving. The second section end part is provided at least with one step for gasket. Gasket is made of pliable sealing gas-and waterproof material and bearing against step surface by one gasket side and against inner shell surface by another side thereof. Steps of bush part are formed within half of thickness of section wall facing outwards, wherein neighboring sections are located so that gaps are formed between ends thereof. Compression ring and additional gasket abutting compression ring are installed in above gap. Additional gasket is made of pliable gas- and waterproof material and bears against inner shell surface by outer ring side and to neighboring section ends by end surface thereof. Length of bush part exceeds that of adjoining part of metal shell. End parts of pipeline sections adjacent to minitunnel mate neighboring end parts of minitunnel or adapter and/or inserted sections are used for pipeline and minitunnel connection. Pipeline is connected to minitunnel after driving the last pipeline section.

EFFECT: reduced material consumption, labor inputs and time required for pipeline laying; increased service life and economy.

The invention relates to the field of construction, and in particular to methods of construction of underground structures, and can be used in the construction of pipelines for various purposes with minitones in their structure under the existing highways without interruption of traffic on them in difficult mining and geological conditions, including, in the presence of hydric soils in the bottom of the tunnel.

A known method of construction of the pipeline with minichannels in its composition (Fedorov NF Veselov SF, Urban underground network and collectors, Moscow, stroiizdat, 1972, pp.261). However, the known method is rather time-consuming and material-intensive.

The present invention is the reduction of construction time, reduce material consumption and the complexity of construction, efficiency of operation, as well as increased durability constructed in the embankment and/or the soil under the existing transportation mainline pipeline segment.

The problem is solved due to the fact that according to the invention in the method of construction of the pipeline with minichannels in its composition, minitunnel performed by successive punching shear in the soil and/or embankment with a simultaneous flow of thixotropic solution of at least two joined as jacking each other and with adjacent sections truboprovodov reinforced concrete sections, each of which comply with the open ends of the end sections, one of which carry the outer side of the open end of the annular groove, in which the set advocating for the end section of the metal shell thickness not exceeding the depth of the groove, the cavity which together with the inside end portion of the section forms a ledge-like socket and the other end of the plot section perform stepwise tapering to an end with the formation of the stub part one ledge under the shell of the socket adjacent sections and at least one annular ledge under the seal of the pliable sealing gazautoservice material closely adjacent one side surface of the ledge and the other end to the inner surface of the shell, while the ledges coupling parts perform within outwards half the thickness of the wall sections, with adjacent sections have a gap between their ends, which set concentrically located in the gap between the sides of adjacent sections of the compression ring and the adjacent outside additional sealing ring of pliable sealing gazautoservice material adjacent the outer lateral surface to the inner surface of the shell and end surfaces to the fact the persons of adjacent sections, the length of the stub part of the end portion of the section perform greater than the length extending beyond the end of the adjacent section of the metal shell, with the ends adjacent to minitunnel sections of the pipeline perform response related terminal region of minitonas or use transition sections and/or inserts, when this Association of pipeline minichannels performed after punching in the soil and/or in the mound last section minitones.

When the location of minitonas in the body of the mound punching hollow concrete sections can be done using mikromotivov complex behind the shield, which at first with both sides of the embankment, in the body which is erected minichannel, perform the start and the admissions of the parties to the mount of embankment slopes, from the starting side mount jacking station on a gantry leg resting on piles, which are transmitted force from jacking station, a platform for supporting a hollow sections, means dredging, and on the receiving side for receiving the shield, and produce alternate punching hollow concrete sections in the mound with the development of the soil in the bottom hole the jet and removing the pulp from the bottom of the pump with the transportation of the tank, which come at the base of the slope of the mound, after selling the infusion of another hollow concrete sections attached thereto the following to be pushing a hollow reinforced concrete section, and the process of pressing repeat.

During the construction of minitonas in the ground punching hollow concrete sections can be done using mikromotivov complex behind the shield through the formation with the starting and receiving sides respectively of launch and receiving pits, and in the starting pit mounted jacking station on a gantry leg resting on piles, which are transmitted force from jacking station, a platform for supporting a hollow sections, means dredging, however, at least from the side push the hollow concrete sections produce bracing of the walls starting excavation metal pipes with tightening boards, and the development of soil starting excavation performed by choosing the soil to a depth of, required for installation of microsite, and punching hollow concrete sections produce in series with the connection between them, and after pressing the last section of minitonas the lower part of the launching pit to the level of last perforated sections fall asleep, with the development of a ground receiving pit and its fastening produce similarly the development of soil and the launching pit and his mount.

Reinforcement of hollow reinforced concrete sections can perform at least one frame, and/Elliotdale rods, and/or nets, and/or with the inclusion of rolled sections and/or with the use of beam structures is a type of flat or spatial farms. The shell can be secured at least to a located at the outer surface of the hollow concrete sections to the frame by means of rods with limb and additionally sancheriv in the body section of the anchor elements.

O-ring gasket can perform variable thickness decreasing in the direction of its end portions to form on the facing side surface, at least one predominantly curvilinear ridge.

The compression ring can perform recessed relative to the inner surface of the wall section with the formation of the annular groove, which is filled with a sealant to the inside surface of the walls of the sections.

At least part of the inner and/or outer surface of the section can perform with a protective coating.
