Abstract

Soil longitudinal anchor, including support plates located in the soil of the trench, a sling device, a traction cable, characterized in that for transmitting the load to the soil it is equipped with vertical support plates located in a plane parallel to the external load, telescopic struts pivotally attached to the vertical base plates and the sling device and inclined at an angle to the direction of the external load, and the length of the telescopic struts is set depending on the width of the trench, ins load and physico-mechanical properties of the soil.

Description

GRZHGOVY CONTINUOUS ANCHOR;

The invention relates to the field of construction and for the implementation of soil anchors used in installation and; rigging.

Known wood-earthen and concrete buried anchors made in the form of wooden shields placed in the ground or concrete slabs located vertically in the plane of the perpendicular applied load. (V.Z. Marshev. Anchors for the construction installation of the BK works, M, 1969). The working load in such anchors is transferred to the ground through a slab placed in the ground, therefore, to increase the bearing capacity, careful rework of the foundation pit is necessary, followed by backfill after installing shields or slabs. A significant drawback of wood-earthen and concrete buried anchors is the possibility of a single use of the anchor material. In addition, the device of such anchors requires a lot of labor and time.

One of the closest analogues is the ground anchor for construction and installation works (USSR Author's Certificate No. 1201405, class E OE D 5/74), which has vertical sheaths buried in the ground to a certain depth depending on the size

applied load. However, the design of such an anchor is quite difficult to manufacture, and for the complete penetration of the shields into the ground

a sufficiently large mass of cargo is needed.

trenches at some distance from each other of two vertical support plates I, parallel to the external applied load. As the vertical base plates, the support shoes of the REM-LOO metal railway flyover can be used. The longitudinal axis of the tranpeia should be parallel to the direction of the external load. The vertical base plates i are interconnected with the help of two telescopic spacers d, which take the external load through the sling device 3 and transfer it to the base plates 1, and through them to the ground. The telescopic arms ii are interconnected by an axis 4 and are pivotally attached to the base plates I. The vertex of the angle formed by the axes of the telescopic struts id is turned to the side opposite to the applied load. The length of the two spacers should be greater than the distance between the plates.

The installation procedure of the ground basement anchor and its operation is as follows. A trench is being developed in the ground, with dimensions sufficient for the installation of base plates and the smooth release of the cargo rope. The tandem is installed vertically in: close to the ground walls of the base plates I. Then telescopic struts 2 are attached to them, while their length is selected and fixed, taking into account the compression of the soil under the base plates, the distance between the hinges of the base plates was less than the length of two telescopic struts. After this, the telescopic races Z with the second end are attached to the sling device, 3, to which the cargo cable is connected. In this case, it is necessary to strictly observe the orientation of the vertex of the angle formed by the spacers. After the load is applied, the transport device 3 tends to move in the direction of its application, but since it is pivotally connected to // Jffb f / y

  . . , leskopicheskuyu 1p. To the razdorkamu, the load is evenly transmitted through the base plates I to both walls of the trench. After removing the load, the longitudinal longitudinal anchor is removed from the soil.

Installation of soil longitudinal anchor and its dismantling

It can be made both element-wise and in complete form. The dimensions of the base plates, the width of the trench and the range of variation of the length of the telescopic struts depends on the magnitude of the external load and the physical and mechanical properties of the soil.

Using the proposed longitudinal longitudinal anchor can significantly reduce the amount of earthwork, reduce the time and complexity of mounting and dismantling the anchor, use the anchor many times, and due to the uniform distribution of the load on the two walls of the trench, increase the bearing capacity of the anchor compared to the well-known wood-earthen and concrete buried anchors .

The industrial manufacture of the proposed longitudinal longitudinal anchor is not very difficult; in necessary cases, this anchor can easily be made from prefabricated elements of the REM-500 railway flyover.
