Description

The purpose of the invention is to increase the productivity of the installation by ensuring the continuity of the process of removing the developed soil from the bottom.

The goal is achieved as a result of the fact that the device for removing soil from the bottom additionally contains sections that are made of rigidly interconnected by means of rods of driving carriages and are installed next to the scoop, the length of the first section being shorter than the subsequent ones, and the scoop and carriages are hingedly mounted pushers and stops for limiting the movement of pushers to the side

penetrations.

I - FIG. 1 given the scheme of the proposed installation; in fig. 2 is a section A-A in FIG. If in FIG. 3 is a side view of a shutter with a pusher; in fig. 4 scheme of the first section of the installation

The installation for the trenchless laying of pipelines contains a device for the distance of the soil from the bottom, which is made of the first section of length E, including the scoop 1 open on both sides with the pusher 2 pivotally suspended on the scoop jumper, the carriage 3 with the drive 4 and the speaker 5 and two connecting rods b.

The device for removing soil from the bottom further comprises subsequent sections, respectively 2 and 6J long, which consist of two carriages 3 with a drive 4 (or without it) and pushers 5, two connecting rods 7 and two - 8 that serve to connect with previous section. All connecting rods are fixed.

The length 6 of the first section is less than the lengths E and d of the subsequent sections. At the same time, the length of each section (both the first and subsequent ones) is less than its stroke and is adjusted by installing one 8 or two pairs of 7 and 8 connecting rods, as well as changing their length ..

Pushers 2 and .5 consist of a segment 9 welded to it by two ears 10 and two axes 11, which ensures rotation (raising and lowering) of the pushers 2 and 5. The rotation of the pushers 2 and 5 along the course of penetration is limited by the corresponding stops 12. The levers 13 prevent the pusher segment 9 from deforming.

On the body of the working body 14 pivotally suspended valve 15, is fixed by means of the latch 16 in a vertical position.

The carriages 3 move on two rollers 17. To remove the soil from the pre-well trench,

for example, a soil thrower 18, which is attached to the tail end of the next (last) pipe 19.

The installation works as follows.

The working device and the pipeline feeding mechanism are turned on, and then the first section of the crushing device comes into operation, which consists of the following steps (Fig. 4).

I. The return movement of the section. Scoop 1 produced a set of portions of soil (B).

II.Aviable section movement for stroke length. A piece of soil (B) moved with a shovel 1 in its extreme position.

III. The return movement of the section. A piece of soil (B) is pushed out of the scoop 1 by the flap 15, after which in the course of the face, the segment 9 of the flap 15 is unlocked by the jumper of the scoop 1 and turned towards the bottom, skipping the scraper jumper. Scoop picks up the next portion of soil (B).

.IV. Translational movement of the section. The ground portion (B) is moved in scoop 1, and the ground portion (B) is moved to the stroke length of section P by the push rod 2 of scoop 1.

V. The return movement of the section. Portion of soil (B) remains at the place of delivery. The pusher 5 of the first section, raised by a portion of the soil (B), returns to its original (lowered) position under the action of its mass. A portion of soil (C) remains in front of gate 15, which pushed it out of scoop 1. Scoop I produces a set of another portion of soil (D).

VI. The actual movement of the Portion soil section (H) is moved in scoop 1. The soil portion (B) is moved by the pusher 2 of the scoop 1. The soil portion (6) is moved by the pusher 5 of the first section.

During the next forward movement of the system, portions of the soil (B) (and then all subsequent ones) move the pushers of the 5 subsequent sections.

Since the first section is located in the first laid pipe (when pipes are laid using the method of increasing the next pipe), starting from the sixth stage, a continuous pulsating supply of soil to the thrower 16 occurs. d.

Claims (2)

During the time spent on each reciprocating movement of the system, the working body acquires the next portion of soil. it is set with a scoop 1 and fed into the thrower 16. Soil from the bottom goes to the tail end of the next expanded pipe to the thrower of the soil. After the removal of the soil and the buildup, the pipes successively increase the next successive section respectively. The lengths of the next pipe and the subsequent section K are equal, so that the rollers 17 of the carriage 3 after the end of the translational movement of the section does not extend beyond the end of the next pipe. The length of each section of section B is less than the length of its stroke ty by the value of a is the distance from the location of each portion of soil to each carriage 3 necessary for the unrestricted rotation of the pusher 5 under its own weight. The size a is compensated under the conditions of a constant length the pipeline between the extension of the pipeline and the next pipe due to the passage into the previous pipe of shorter length of the first section. Under the conditions of equality of the lengths of the following sections and the next expandable pipes - the same course. both the first and the subsequent sections, as well as the need to compensate for the value of O, the length of the first section is K, - a, thus the first section is shorter than I subsequent by the value of q. In relation to the stroke length η the first section is shorter by e, -B Cei-Ki) - (ei-a): ei + cj-e -fa ia, the valve 15 is intended for unloading (pushing) the soil out of; scoop 1, that provides the possibility of further advancement of this portion of soil by the pusher 2. Scoop 1 has a channel on which the pusher 2 is pivotally suspended and there are two stops 12. In connection with this, the valve 15 is turned in both directions, the pass is loaded j or the empty scoop 1, and during the period of the load (ejection) of the soil from the joint 1, it is held in a vertical position with the help of the latch 16. During the fast first movement of the first section (stage II, fig. 4), the lintel of the loaded shovel 1 deflects the flap 15, which, skipping the shovel 1 (its jumper with the pusher 2) slides along the jumper and portions of the soil B, and then under the action of its mass takes up a vertical position and it is sealed with latch 16. During the return movement of the section (IG stage), the ground is unloaded (pulled out) of the scoop 1 by the flap 15, which is fixed in the vertical position. The soil ejected from the scoop 1 turns (raises) the pusher 2, which slides along the surface of the ejected soil by the plane of the segment 9. The jumper of the moving scoop 1, when approaching the shutter 15 (pressing the latch 16) unlocks, bla- at which the flap 15, under pressure of the bridges of the scoop 1, rotates toward the bottom and passes the scoop, and then, under the action of its mass, presses the initial position, with the unloaded from scoop 1 portion B located near the flap 15. Segment 9 of the pusher 2 as the scoop 1 advances slides off the unloaded portion of soil B and lowers to its original position under the action of its mass. The return movement of the first section ends with a set of 1 portion of soil in the scoop. At the next forward movement of the first section (stage Ij, the pusher 2 rejects the valve 15, pushes the portion of soil B in front of the valve 15 into a position from which the pusher 5 then moves it The same section (stage I), etc. The angle of rotation of the flaps 15 depends on its length (height) of its hinge location) and the height of the web in the scoop. The angle of rotation of the flaps (the angle between the two extreme positions of the deflections of the flap) is close to IBOP. The simultaneous operation of the working body, the delivery of the laid pipeline and the system of removal of the soil allows for the continuous development and transportation of the soil, i.e. continuous laying of the pipeline (with the exception of breaks for lowering the alternate pipe into the trench and welding). In the production of large-block method, when all pipes are welded in advance into one whip, work is carried out continuously until the end of penetration.
