SU1752972A1 - Device for sealing seams of prefabricated lining, and method of mounting it - Google Patents

Abstract

Usage: the invention relates to building technology and is intended for embedment of the joints of submerged structures. The assembled joint unit is inserted into the seam of the support and is turned 90D around the longitudinal axis. After that, fix the position of the joint with clamping bolts and clamps. The bag is then released from its extended position. Inside the bag, the cement solution is pumped through the carrier tube. 2 sp.f-ly, 1 ill.

Description

The invention relates to construction equipment and is intended for monolithing the joints of submerged structures.

A device for sealing seams of team supports, including a cement gun and a gunning unit, is known.

A disadvantage of this device is its complexity.

The closest in technical essence and the achieved result to the invention are a device for sealing seams of team support, including a pipe for supplying a hardening solution and a lining, and a method for its installation, including placement inside the pipe seam, installation on the seam of the seam and pumping it through solution.

The disadvantage of these devices and methods is the low reliability of the fixing of the fixed voids.

The purpose of the invention is to increase the reliability of sealing anchored voids.

The goal is achieved by the fact that in a device for sealing joints of team lining, including a pipe for feeding hardening mortar and lining, the pipe is equipped with a bag with a spring placed in it freely with the possibility of its removal, and a tension system consisting of two clamps. on which the bag is put on, and fixed on the clamps with the ends of two tons of g, while the clamps are rigidly mounted on one end of the pipe, and the latch on the other, with the free ends of the pull-tension system being bent and have clamping bolts.

This goal is also achieved due to the fact that according to the method of mounting a device for sealing seams of team lining, including placing a pipe inside a seam, installing a seam on the seam and pumping the mortar through the pipe, put a bag on the end of the pipe that is stretched with a spring. Perpendicular to the lining, place its end with a bag for lining, turn it 90 °, fix it firmly inside. The seam and remove the spring from the bag before pumping the cement slurry, and installing the latch after a set of cement slurry strength.

Significant differences of the proposed device for sealing seams of the team lining include supplying the pipe with a bag with a spring placed in it freely with the possibility of its removal; supplying the pipe with a tension system consisting of two clamps, onto which the bag is put, and fixed on the clamps with the ends of two tons of grams; installation of clamps rigidly at one end of the pipe, and flat panel at the other; the implementation of the free ends of the r g after the gut and supply them with clamping bolts.

The first two of the above differences of the proposed joint fixing device for team lining allow you to create an anchor that securely connects the lining with the support; the remaining differences will make it possible to improve the fastening of the panel to the lining, i.e. also increase the reliability of the seal.

Significant differences of the proposed method of mounting a device for sealing seams of team lining include the placement of a bag stretched by a spring at the end of a pipe; the location of the pipe is perpendicular to the bearing; setting the end of the pipe with the bag for the lining, turning it through 90 ° and rigid fixation inside the seam; removing the spring from the bag before pumping the tampon solution; installation of a slat after a set of cement slurry strength.

All the above-mentioned differences in the proposed method of mounting a device for sealing joints of team lining allow one to realize the advantages described above, i.e. leads to an increase in

reliability of fixing of fixed voids and therefore directly related to the achievement of the goal.

The drawing shows a device for sealing seams team lining, a longitudinal section.

The device includes a spatula 2 connected to the lid 1 and a filler material Z placed within the seam 3. The splicing unit 2 with the lashing 1 is made in the form of a supporting pipe 5, bag 6, spring 7, supporting rope 8, clamps 9 and t 10. Clamps 9 are rigidly fixed to the end of the carrier tube 5 (for example, using a weld 11), they are put on bag 6, stretched with a spring 7 in the plane of clamps 9 and fixed on clamps 9 with a retaining ring 12, One ends of t 10 are attached to the clamps 9, while others are fitted with clamping bolts 13, intended nye for clamping the support frame 1. In the central portion of rods 10 mounted supporting base pipe 8. The rope 5 of the support tube 5 is mounted for pressing flat strips 2 by a nut 1.

The method of installation of the device for sealing seams of team support is implemented as follows.

The assembly is assembled, including support pipe 5, clamps 9, bag 65, spring 7, pulls 10, support rope 8, retaining ring 12 and clamping bolts 13. With this, spring 7 is placed in bag b expanded (position I). When assembled, the joint unit is inserted into the seam 3 of the lining 1 and is rotated by 90 ° around the longitudinal axis (in the drawing, the node is shown after rotation). After that, the position of the joint is fixed by means of clamping bolts 13 and clamps 9. Then, the bag 6 is released from the extended position, for which the spring 7 is moved from position I to position II. Inside the bag 6, the cement slurry 15 is pumped through the carrier tube 5. After the cement slurry 15 has hardened, a plate 2 is installed, in which a hole 16 is provided for the carrier tube 5. The plate 2 (is pulled to the lining 1 with a nut and a washer 17 using filled solidified
