Abstract

The proposed utility model allows you to implement a new technology for laying road tunnels or tunnels for other purposes, under river beds or under the bottom of other shallow water areas. Mainly, this utility model can be used as a temporary enclosing and simultaneously supporting element of the hydraulic structure in a closed section of the bottom of the water area, and can also be used in the construction of bridge supports. A feature of such a utility model is that they use a single enclosing structure that simultaneously carries a buoyant controlled structure, manufactured in the factory in the form of a dock with no bottom.

Description

This utility model relates to hydraulic engineering, mainly to the technology of laying road tunnels or other tunnels, under river channels or under the bottom of other shallow waters. Mostly, this utility model can be used as a temporary enclosing and simultaneously supporting hydraulic structure in a closed section of the bottom of the water area, and can also be used in the construction of bridge supports.

The invention is known with the name "System for temporary drainage of the bottom section" (see USSR author's certificate No. 1067142, MKI E 02 D 5/20, published in B.I. - 2 - 1984). This system is formed from a set of enclosing parts, each of which is a shell having any shape and made, for example, of metal

sheet pile, and the shells are given an elliptical or circular, or parabolic shape in plan.

However, the prototype has a significant drawback, namely: the enclosing part of the known system for temporary drainage of the bottom section cannot be used as a supporting structure during the construction of the tunnel inside the mentioned hydraulic structure.

The objective of the proposed utility model is the creation of the enclosing part, with the ability to be a supporting structure in the system for temporary drainage of the bottom.

The problem is solved and in accordance with this solution in the known enclosing part of the system for temporary drainage of the bottom section containing the shell, ACCORDING to the proposed utility model, a dock is used as a shell, made with elements of controlled buoyancy and without bottom, and elements of controlled buoyancy are located or on the outside of the walls of the dock, or mounted in its walls, and the walls themselves have a height greater than the depth of the site selected for the construction of a temporary hydraulic barrier, while the wall has a strength that can withstand hydrostatic pressure from the water column.

Such a new technical solution, with its entire set of essential features, allows you to create a enclosing part that can simultaneously be a supporting hydraulic structure for temporary drainage of the bottom section.

Compared with the prototype, the claimed enclosing part of the system for temporary drainage of the bottom section has a significant difference, which consists in the fact that they use a single enclosing structure that at the same time carries a buoyancy-controlled structure manufactured in the factory in the form of a dock with no bottom.

A patent information search carried out by the applicant showed that the claimed combination of essential distinguishing features of the proposed utility model was not found in published information sources. Therefore, the claimed utility model can be considered new.

In essence, a new enclosing and at the same time bearing part of the hydraulic structure is proposed, which is carried out in the factory as a floating dock without a bottom. On this design, it is possible to place crane equipment, energy supply facilities and storage areas for building materials. This single floating structure is delivered to the intended installation site, and upon completion of construction work inside the enclosed space of the structure, transport buoyancy is returned to it and towed to the next section of the tunnel construction.

The essence of the claimed utility model is illustrated by drawings, where:

Figure 1 is a cross section of a hydraulic structure located in a transport position.

Figure 2 is a cross section of a hydraulic structure installed at the bottom of the water area.

Figure 3 is a cross section of a hydraulic structure installed at the bottom of the water area, inside which construction work has been completed.

Figure 4 is a cross section of a hydraulic structure located in a transport position and having built-in elements of controlled buoyancy.

5 is a cross section of a hydraulic structure located at the bottom of the water area and having built-in elements of controlled buoyancy.

6 is a cross section of a hydraulic structure located in the transport position (option) and having controlled buoyancy elements located on the outside of the structure.

The practical applicability of the proposed utility model is illustrated by the following description.

The enclosing part 1 of the system for temporary drainage of the bottom section is made in the form of a single floating dock structure without a bottom part (Figs. 1, 2, 3, 4, 5, 6). It has elements 2 controlled buoyancy, which in one case are located on the outside of the dock (figures 1, 2, and 6), in another

case - built into the walls of the dock 1 (Fig.4 and 5). In the first case, floating means, for example, barges or auxiliary vessels, are used as elements of controlled buoyancy. In the second case, the tanks mentioned can be integrated into the walls of the dock. The walls of the proposed design have a height h greater than the depth H of the water area 3 (Fig. 1). Moreover, the wall thickness b has a strength capable of withstanding hydrostatic pressure from the water column in the drained part of the water area.

The proposed design for a utility model is used as follows.

Initially, in the factory, a protecting and simultaneously supporting part 1 of the hydraulic structure is made in the form of a dock, which does not have a bottom. This design may have, for example, the following geometric dimensions. The width of the dock is 30 meters (for posting through the drawbridge of existing bridges), length - 60 meters, height - 15 meters. In one case, the controlled buoyancy elements 2 are located on the outside of the structure, and in the other, blown tanks are built in (Figs. 4, 5). These elements 2 buoyancy, provide transportation of the dock 1 and landing it on the bottom of the water. At the same time, the upper part of the mentioned structure is aligned horizontally, which allows to place crane equipment, sites for temporary storage of building materials, office premises on its upper part. The horizontal alignment can be carried out by planning the bottom of the water area and the extension of the knives 4 (figure 3). To develop the bottom soil inside the enclosed space, tongue-and-groove walls 5 are erected. Then water is removed from the enclosed space and construction tunnel works are carried out using a dry open method. Moreover, floating cranes, concrete floating plants, barges, etc. can be moored to such a structure. Upon completion of construction works of this design, transport buoyancy is returned and moved to the next section of construction.
