SU103926A1 - Hydromechanized installation for drilling an underground well without opening the pavement and laying into it a block of sewage pipes for electrical, mainly telephone, cables - Google Patents

Description

The subject of the invention is a hydraulic installation installation for 11o;;, zemion well. After opening the pavements H, laying a block of kaializiltsin pipes into it under e.potricheskie, advantage but telephoto, cable.H, pc; 11 () h, a 1 drill for pa.iMhrua soil with irradiated to it a bludgeon of pipes and suction dredger for suction, installed outside the well.

The known installations do not allow the CT to perform the drilling of a well and the laying of a block of pipes sufficiently quickly.

GZ is found in the installation to speed up the npoueccoii borehole drilling and the installation of the block T1). inside this block, a puffer chute for suction of a nulpa with a suction dredger, and the laying of pipes is performed simultaneously with the development of a well.

FIG. 1 shows a schematic longitudinal section of installation; in fig. 2nd plan; pas figs. 3

cross section of the head section of the installation and sections along AA, BB and BB.

The operation of the installation is based on the development of the soil and the formation of a well 1Y with a TioMouibK) water jet, which has sufficient speed and pressure. The installation provides the laying of a current of seven asbestos-cement pipes to bottoms (with a depth of approximately 100 mm, d. About -5 m each.

Before laying iia6oT and laying the pipeline, at the ends of the section, two trenches (and / and) are excavated and fixed. The dimensions of the first one are approximately 4.5 x 2 m, the second 3 x 1.5 m. The pits are interconnected by the pioneer well, using a diameter of 50-100 mm. In the second trench, a manual winch (and cable 2) is installed, by which the well is pulled through the first trench. K. The end of the cable in the pit / fasten the gantry section 3 of a steel pipe with a diameter of about 500 mm and a length of 1.1 g. in jioiuiyio sgktsik i; k.

The transfer of the repelling force to the pipe current is accomplished by the installation of a pipe //, which is impacted in the central channel. One end of the pipe is attached to the head section, the other end with the help of a coupling (limiter) transfers the force to the block.

The head section (. 3) is a stationary pipe 12 with a crown 13, which serves to reduce the soil's resistance. The sealed diaphragm 14 section is divided into two parts. In the left part passes H1lang pumping pulp 15, as well as CRE. The pipe unit is fed together with the chuck used at the same time to supply water to the nozzle. The right part of the section is divided into two compartments with round bar pz of round bars 16. The main purpose of the lattice is to retain coarse fractions of soil and solid inclusions to prevent the ground pump 7 from clogging. Between the diaphragm 1 {and the grid there is a four-tube block of nozzles 18, b wired with a conduit 19 and eroding jets. A winch cable ending with a die 20 is attached to traverse 21, welded to the walls of the pipe and to the npyTF.HM of the trajectory. To obtain sufficient strength of the traverse, cut the brace 22. For normal Noy work sucker nsos eio

it must be continuously immersed in water; therefore, the level must not be maintained below the axis of the P – V axis. Zemktos is iodine-in, i.e. it is: 1 cm of it below the head section. To this end, the suction dredger is installed in the side-floor of the pit (Fig. 2).

The paranasal sections are made during short breaks (5-6 minutes) directly in the trench. Coupling pipes are centered; 1 of 3 mm stainless steel clean steel, about 3 mm, in the middle (|) T1) 1, on the inner side, a stopper is welded to the end of the pipeline: 1) pipe shear. . The place of pipe connection is crimped with a common clamp of sheet steel or, alternatively, all the couplings are welded and one common, but without the clamp.

The effectiveness of the development of soil by a stream of water is influenced by the rate of outflow of the jet from the nozzles, the nanor of water supplied to the nozzle, the distance from the nozzle to the developed soil, and the shape of the developed bottom. All these factors for underground penetrations of the hydromech in a low-volume manner require a more thorough study and determination of their numerical parameters by experiment. The pre-selection of the operating mode and the selection of valves for water shinging and pulp removal are made using the Iroko data of the used hydro-mechanized method of developing open faces.

The water consumption of soil transport soil 1 depends on the properties of the soil and varies in the range of tenors. Based on the experimental dates, it can be assumed that in the most unfavorable cases, the pulp consistency will be equal to 10-12%, therefore, the suction pump's hourly capacity should be up to 40 l / h s. In terms of performance, these conditions are satisfied by a 2IP suction dredger.
