Description

one

The invention is carried out for port hydraulic engineering construction of mooring and shore protection structures of pile shells, large diameter shells, slabs and massifs, the structures of which require ground-proof butt joints of vertical joints between these precast concrete elements.

The aim of the invention is to increase reliability when using elements of supporting and hydraulic structures in the ground-tight butt joints.

FIG. 1 shows a sealing element, a general view of FIG. 2 is the same in the plan; in FIG. 3 - sealing element. In the plan, installed between joined elements with curved walls, in Fig. 4 - the same, installed between joined elements with straight walls.

The sealing element includes a shell 1 of elastic material and an extension of the insert 3 and elastic elements 4 placed in its cavity. The insert 3 is made in the form of a rigid core with a trapezoidal cross section protruding beyond the ends of the shell 1 and has a single-sided

a bevel 5 at one end and elastic outlets 6 discretely arranged along its length, combined by flexible links 7. The elastic elements 4 are made in the form of longitudinal, installed parallel to the core, rollers of

rolled plastic attached to flexible connections 3 and 7.

The sealing element is made5 as follows.

The insert 3 is made in the form of a rigid trapezoidal cross-section core of concrete. Elastic outlets 6 and flexible couplings 7 may be pre-provided in the manufacture of the core reinforcement cage and welded to the mortgage parts (not shown) after the reinforced concrete liner has been made. By that time, the elastic elements are fixed to the elastic releases 6. The prepared insert 3 with the elastic ends 6, the flexible links 7 and the elastic elements 4 are covered with several

20 layers of non-woven synthetic sheath material 1, forming the usable element.

Prepare the sealing element 25 with the help of a wing (not shown) placed in the gap between the joined elements 8 from the side of the subsequent ground filling (not shown). Under the action of its own weight and thanks to the bevel 5, the sealing element is pressed against the joined elements 8 at the bottom level, then it is fixed in the upper part. Soil backfill (not shown) 2 creates pressure on the sealing element, which contributes to a more tight pressing of the sealing element against the one being joined.
