Description

1.. one..

Изобретение относитс к строительству и касаетс возведени стены в грунте, котора может быть использована в качестве фундамента .или ограждающей конструкции.The invention relates to the construction and construction of a wall in the ground, which can be used as a foundation or fencing structure.

Известна сборно-монолитна стена в грунте, нижн часть которой выполнена из монолитного бетона, а верхн - из сборных панелей, соедин емых между собой и с монолитной частьюс помощью выпусков арматуры 1, .A precast-monolithic wall in the soil is known, the lower part of which is made of monolithic concrete, and the upper part is made of precast panels interconnected and with a monolithic part with the help of rebar releases 1,.

Недостатками известной конструкции вл етс наличие стыков между сборной и монолитной част ми и необходимость закачки тампонаж«ого раствора в зазоры, остающиес между сборными панел ми и стенками траншеи.The disadvantages of the known construction are the presence of joints between the team and the monolithic parts and the need to pump the cement slurry into the gaps that remain between the team panels and the walls of the trench.

Наиболее близкой к изобретению вл етс сборно-монолитна стена в грунте, включающа панели, вертикально установленные в траншее и обращенные друг к другу своими боковыми торцами , выполненными с вертикальными . пазами, и бетон за 1оноличивани , размещенный между панел ми 2 .Closest to the invention is a precast-monolithic wall in the ground, including panels vertically mounted in a trench and facing each other with their lateral ends made with vertical ones. the grooves, and the concrete for the imbedding, placed between the panels 2.

Недостатком этой конструкции вл етс необходимость установки арматурного каркаса бетона замоноличивани в глинистый раствор, в результате чего из-за снижени сцеплени арлThe disadvantage of this design is the need to install the reinforcement cage of the concrete to grout in the mud, as a result of which, due to the reduced adhesion of the arles,

с бетоном, уменьшаетс несуща способность конструкции. with concrete, the bearing capacity of the structure is reduced.

Целью изобретени вл етс повышение несущей способности стены.The aim of the invention is to increase the carrying capacity of the wall.

Указанна цель достигаетс тем, что в сборно-монолитной стене-в грунте , включающей панели, вертикально установленные в траншее и обращенные друг к другу своими боковыми торцами, This goal is achieved by the fact that in a prefabricated monolithic wall-in the ground, including panels, vertically installed in a trench and facing each other with their side ends,

10 выполменныгли с вертикальными пазами, и бетон замоноличивани , размещенный между панел ми, кажда панель в вертикальном продольном сечении выполнена переменной ширины,, увеличива15 ющейс от ее середины к верхнему и нижнему торцам, причем отношение ширины панепи на ее верхнем и нижнем торцах к ширине в ее середине нахо-дитс в пределах 1,5-3,0.10 are extruded with vertical grooves, and the monolithing concrete placed between the panels, each panel in a vertical longitudinal section, has a variable width, increasing from its middle to the upper and lower ends, and the ratio of the width of the panel panels at its upper and lower ends to the width its middle is in the range of 1.5-3.0.

На фиг. 1 изображена панель предлагаемой стены, продольный вертикальный разрез;на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows the panel of the proposed wall, a longitudinal vertical section; FIG. 2 shows section A-A in FIG. one.

Предлагаема стена в грунте состоит из панелей 1, кажда из которых имее.т по торцовым гран м вертикальные пазы 2 с арматурными выпусками 3.The proposed wall in the ground consists of panels 1, each of which has vertical grooves 2 along the end faces with reinforcement 3.

Claims

The width of the panel in the horizontal vertical section of the received variable, 30 and the ratio of the width of the panel at its upper and lower ends to the width in its middle is in the range of 1.5-3.0. The specified limits are not related to the size of the wall block, on the one hand, due to the strength of the block for mounting and transport loads, and on the other hand, the carrying capacity of the wall in the ground. The construction of the wall in the ground are as follows. After the development of the trench, the prefabricated panels are lowered into it so that the ends of the adjacent panels adjoin each other. In the vertical channels, formed between the ends of the adjacent panels with the grooves 2, the pipes for concreting are lowered and the monolithic concrete is laid using the vertical-moving pipe method. Monolithic concrete fills the channels and cavities formed between the panels in the middle part of the wall, ensuring reliable contact between the ground and the wall along its side surface. . The proposed design allows to significantly increase the bearing capacity of the wall in the ground due to reliable contact between the ground and the wall and the installation of working reinforcement only in the prefabricated part of the wall. Claims of the invention A prefabricated monolithic wall in the ground, including panels vertically installed in a trench and facing each other with its lateral ends made with vertical grooves and cementing concrete placed between the panels, in order to increase its bearing capacity, each panel in a vertical longitudinal section is made of variable width, increasing from its middle to the upper and lower ends, and the ratio of the width of the panel at its upper and lower ends to the width in its middle at is within 1.5-3.0.
