Description

The invention relates to the design of capacitive structures with retaining walls, for example for liquids, bulk solids, such as tanks, septic tanks, pools, aerotanks, wells, which consist of external and internal retaining walls (partitions) and the bottom.

Known capacitive structure, consisting of wall panels and base plates, manufactured separately and connected to the installation.

The wall plate is installed in the trapezoidal groove of the base plate on the wedges, followed by concrete grouting [1] ·

The closest to the proposed is a capacitive structure, including walls of panels with a supporting fifth and the bottom in the form of a slab mounted on a concrete preparation, and the heel has fittings for connecting with the bottom reinforcement made in two rows for welding, and the concrete preparation is solid and the joint is monolithic with concrete [2].

A disadvantage of the known retaining walls of capacitive structures is the rigid coupling of the wall plate with the foundation 2

coping plate that serves as the bottom of the capacitance structure. In case of rigid mating, the tensile force extends to the upper reinforcement of the bottom. Due to the presence of tensile stresses in the top 5 of them, the fibers of the base plates of the bottom are reinforced at the top and bottom of the working reinforcement. Changing the sections of the reinforcement according to the law of changing the bending moments in the bottom is non-technological.

¹⁰ In addition, the disadvantages of the known structures include the need for the joint decoration of joints, the device of continuous concrete preparation and processing of the joined surfaces, as well as the inevitability

15 devices of working joints with monolithic bottoms, since continuous concreting of the entire bottom is almost impossible '-' ^ '': but. At the same time, the reliability of the watertightness of the bottom depends on meteorologists for ₂₀ and other conditions, and the rigid coupling of the walls with the bottom is sensitive to subsidence of the bases.

The purpose of the invention is to reduce the consumption of materials and the complexity of installation of the structure.

This goal is achieved by the fact that in a capacitive structure, including walls from panels with a supporting heel and a bottom in the form of a slab, mounted on a concrete preparation, the heels of the wall panels are installed with a gap relative to the bottom and _{5 are} hingedly connected with it by elastic gaskets, and the side walls of each supporting the heels are made with a slope that has a slope to the bottom, and the bottom, at the interface with the wall of the supporting heel, has a bevel parallel to it, and the plate is made of a composite of interconnected elements, and the concrete preparation you It is filled in the form of tapes, placed under the supporting heels of the wall panels and the places where the elements of the bottom are joined together. ₁₅

FIG. 1 shows a capacitive structure, a cross-section; in fig. 2 - the same, top view; in fig. 3 - section A — A in FIG. 2

The capacitive structure consists of a wall panel 1 with a two-sided supporting 20th fifth, foundation plate 12, serving as a bottom, concrete strip preparation 3, located under the heels of the wall panels 1, random beam 4, elastic gaskets 5, continuous across the entire width of structures _{2ί pulls} 6.

Capacitive construction works as follows.

When filling one of the compartments, the lateral pressure tends to overturn the wall plates of the compartment to the outer sides around the outer edges of the compartment heel ribs. Hermetic immutability of wall plates is provided if the heel pull-out force to the lateral surfaces is equal to _: but less than the bottom support pressure. Conditional equilibria express unequal ^! . e _{uie +} about ₄ + c ₂

where b is the height of the compartment filling;

B - the width of the heel of the wall plate is 40;

Y is the density of the liquid;

О ,, О ₂ - the weight of the wall panel and the bottom;

B is the distance between the side surfaces of the heels of the wall panel. ⁴⁵

Considering that in capacitive structures, the bottom is reinforced along the lower and upper fibers so that it is almost equally strong when bending up and down for the proposed retaining wall, concrete preparation is arranged in a ribbon so that there is a gap between the bottom and the ground. This allows you to transfer the full pressure of the bottom to the heel to keep it from tipping over and avoid making expensive solid concrete preparation and ground leveling, as well as using prefabricated plates for the bottom. According to calculated data, the reduction in the cost of capacitive structures from the elimination of work on the sealing of joints and the device of continuous preparation under the bottom and the planned foundation is 10-15%.
