SU953107A1 - Method of correcting structure position - Google Patents

Description

produced to obtain a solution density at which the draft of the supporting structure corresponds to the ratio

h KU. (R, -R ")

bs

where k is the interaction coefficient of the process ingredients;

Vj, is the initial volume of fluid in the system;

PP is the density of the solution when the supporting structure settles on the value of hj PO - the initial density is liquid. bones{ .

j, is the volumetric weight of the bulk material; . S is the bearing area of the bulk material.

At the same time, it is preferable to separate the bulk material with polymer films into separate compartments isolated from each other before supplying water and supplying water to them separately.

FIG. 1 shows the foundation, vertical section; in fig. 2, too, with isolated areas.

When correcting the position of the structure by the proposed method, the foundation glass 1 is filled with bulk, sodium-soluble sodium chloride 2, on which the supporting structure of structure 3 is installed. In the walls of glass 1, channels 4 are made, one of which is connected to the cavity cavity in the lower part, and another - with a cavity cavity in the level of the top of the bulk material / Filters 5 are installed in the channels 4. Channels 4 are brought to the level of the floor using transition nozzles 6 to which the connecting pipes 7 with the tank 8 are connected. and line 7 is put pump 9, the flow branches to e - valve 10. In / tank 8 arranged measuring device 11 density. In addition, the bulk material can be divided into separate insulated compartments, liquid-insoluble polymer films 12, which are attached to the bottom and walls of the base cup.

Depending on the washout mode, the filters 5 on the channels 4 can be made of a different structure, and the fluid flow in the system can be set in both directions.

In the process of correcting the position of a structure, one system with a closed cycle or several systems can be applied, which can be installed at once for one supporting structure, for several structures or for the entire structure.

The bulk material can be placed in a foundation cup in a cramped state or in a free, for example, in the form of a support cushion, which can be a film shell filled with bulk material, and the base glass itself can be present, and the load from the structure is transmitted directly through the support cushion on the soil basis.

The essence of the method lies in the fact that through the bulk material I pass a certain amount of liquid in a closed Cycle.

Depending on the initial volume of the fluid in the system, about or its initial density rd is washed out of the granular material into the solution exactly the exact amount of substance. In this case, either the degree of saturation of the solution is reached, at which further dissolution is impossible, or any other lower density of the solution under the condition that all liquid is removed from the bulk material to stop the dissolution process. Moreover, at any moment of time, including the initial and final, the density of the solution is directly measured by the instrument g, in accordance with the above relation,. have a direct connection with the draft of the supporting structure; in a particular process, either the initial density of the liquid or the volume of liquid in the system varies and, at the same time, the support structure h is expressed as a change in density (PP-ro) in tabular or other form that is consistent with scale measuring instrument density.

Since basement inevitably causes a natural increase in humidity due to the close presence of groundwater, stormwater or process effluent, soluble water is used as a bulk material, such as sodium, potassium chloride, lithium chloride, or a mixture of them, depending on the required solubility value. In this case, sodium chloride, for example, is a concrete additive that accelerates the hardening and does not have an adverse effect on concrete.

Claims (2)

Salinization of the concrete from the inside of the glasses is useful, since groundwater infiltration through the walls of the foundation glasses practically stops. Aqueous solutions of these salts are also harmless to structures, they penetrate into fine pores and wet the surface of the particles in the bulk material, facilitate its uniform leaching, and are easily pumped through the system with conventional liquid hydraulic or vacuum pumps. The method allows simply and reliably with insignificant energy, labor and material costs and with a high degree of accuracy to repeatedly correct the position of the maintained structures, as well as to change the vertical attachment of structures in a wide range, determined by the height of bulk material a la. Claim 1. Method of correcting the position of the structure, whose supporting structures are placed in the foundation glasses, including filling the latter with loose material, supplying the bulk material with water and removing it, characterized in that, in order to improve the accuracy of adjusting the process of correcting the structure, the foundation glasses is filled with a material that is soluble in water, and water is supplied to the material until density is obtained; solution, in which the draft of the supporting structure of the in and out of the designation number corresponds to the scheme - KUa (fl, - PC) - Yc s e K coefficient of interaction of the process ingredients; the initial volume in the PP system is the density of the solution when the supporting structure settles on the value of h; pb is the density of the liquid; Y ,, - volumetric weight of the bulk material; S is the reference area of the bulk material; 2. Method POP.1, distinguished by the fact that, before supplying the dusts, the bulk material is divided into separate compartments with individual films from one another and the water supply to them is carried out efficiently.
