Abstract

FIELD: civil engineering. SUBSTANCE: compacted soil filler is placed in a hard shell preliminary positioned in the wall. Cement slurry is used to fulfill the operation. Then clearance between the shell and filler are filled with cement slurry followed by installation of another shell in the wall being erected. EFFECT: reduced man-hours when erecting walls, broadened application of wall with soil filler. 2 cl, dwg

Description

 The invention relates to the construction, and in particular to a method of erecting a wall of hard shells filled with a granular body, such as soil, a mixture of soil with solid materials, and intended for use in the construction of low-rise buildings for various purposes, fortifications, retaining walls, etc.

 There is a method of erecting wall structures, in which they install rigid wall shells of plates, connect them with wall ties and fill the space between the panels with filler [1] This method is notable for the considerable complexity of installation associated with the erection of walls.

 A known method using panels of a flexible closed shell, including inflatable elements and a liquid filler to give rigidity [2] This method does not allow to obtain sufficient structural stability at the time of filling with a loose body and is time-consuming.

 Closest to the proposed technical essence is the method of erecting the enclosing wall, which consists in filling sections of the soft shell with soil filler using conductors and a special mounting kit and fixtures [3] In this method, a trench is arranged before filling the shell, a conductor with fasteners is installed at its edges , a soft shell is placed in the cavity between the elements of the conductor and the trench. Then the sections are filled up with a conveyor with layer-by-layer compaction of the soil by vibration and, using a crane, the conductor is rearranged for the device of the next section. However, this method of erecting walls is characterized by considerable laboriousness, limited scope and has disadvantages associated with the production of work with soil in a building site (the effect of precipitation, low temperatures on the condition of the soil).

 The purpose of the invention is to reduce the complexity of building walls, expanding the scope of walls with soil filler, making it possible to build walls with soil filler by traditional methods using masonry mortar, reducing the cost of building walls.

 The essence of the invention lies in the fact that the filler is placed in a rigid shell-box (hollow block with thin walls), which are laid in a wall on a solution by means of mounting blocks or masonry without the use of special conductors and devices.

 The drawing shows a wall being erected by the proposed method.

 The wall is erected as follows.

 In the first case, a series of filled shells (or foundation), previously laid in the wall, is laid and the solution is leveled, then, with dressing and filling of the wall seams, the shell boxes 1 are placed. Next, solution 2 is leveled on the bottom of the shells with a layer of 3-5 mm and laid in the shells as much as possible compacted filler 3, fill the gap 4 with the solution 4 between the side walls of the shells and the filler, after which the sequence of operations is repeated. In this case, due to the difference in the height of the walls of the shell and the upper face of the filler after leveling the solution, a ledge is formed on the mounted parts, which increases the strength properties of the wall.

 In the second case, when filling the shells of significantly larger sizes in comparison with the filler, the latter is collected in the shell on a solution of small filler with ligation of the joints and filling the gaps between the walls of the shell and the filler. As a shell, heavy concrete, reinforced concrete, ceramics, etc. can be used. depending on purpose and wall requirements. The shell depending on the material can be pressed, formed with subsequent steaming and other known methods, for example as hollow concrete blocks. Various soils can be used as filler: coarse-grained, sandy, clayey, production waste in the form of powder or larger solid particles (ash, slag, rubber, etc.). To improve the thermotechnical properties of the wall, expanded clay, perlite, etc. can be added to the filler. To seal the filler, walls for the manufacture of soil blocks, presses and clay brick making machines can be used.

 Thus, the proposed method can significantly reduce the cost of construction of buildings and structures for various purposes, simplify the technology of erection of walls with soil filler (assembly of shells and filler made in the factory or at the construction site), conduct construction of objects from walls with soil filler year-round.

Claims (2)

 1. WAY OF CONSTRUCTION OF THE WALL, including the installation and filling of the shells with a soil filler, characterized in that they use hard shells, which before filling are laid in the wall on the mortar with dressing of the joints, the bottom of the shells is covered with a thin layer of mortar and filled with the most compacted soil filler in the form of a shell, but smaller than its internal dimensions, then the gaps between the shell and the filler are filled with a solution, a mortar bed is made and the cycle is repeated.  2. The method according to claim 1, characterized in that the filler is collected in a shell on a masonry mortar of small filler elements with ligation of the joints.
