Description

The utility model relates to construction and environmental engineering and can be used as anchor and anchor foundations in various sectors of the national economy.

Known wire anchor with a conical tip [1], which includes laying an overlap woven mesh by unwinding rolls with a length of side across the direction of movement of the slope with fastening on the slope anchors with tips. Wire anchor has a conical tip with a guide rod, which takes in the working position the direction coinciding with the wire, which is attached to the anti-landslide structure. The disadvantages of this technical solution are:

the design of the anchor is not sufficiently effective when working on versatile loads;

limited scope.

The closest technical solution is the method of installing pillars [2], which includes the construction of the pit with the installation of pillars in it. At the same time, a lining is placed on the bottom of a rectangular-shaped pit, wire anchors with tips are driven into the ground at the corners, after which gravel preparation is poured into the pit, onto which the base of the column with a shoe is laid, to which the wire anchors are attached and tightened to the corners, and and secured the pillar. The disadvantages of this technical solution are

the design of the anchor is not sufficiently effective when working on versatile loads;

limited scope.

The purpose of the utility model is to increase the efficiency of fixing and reliability of the anchor structure.

This goal is achieved by the fact that the combined anchor consists of two components: the upper - pile anchor and the lower - wire anchor with a conical tip, recessed to a depth equal to

Проволока проволочного анкера проходит через внутреннюю цилиндрическую полость сваи и залита после установки, комбинированного анкера, композиционным материалом. В качестве композиционного материала можно использовать высокопрочный бетон или другой материал, который обеспечит прочное сцепление проволоки со сваей. Величина

- расстояние от конца свайного анкера до конического наконечника является расчетной, определяется по аналитическим зависимостям и зависит от физико-механических характеристик грунта. В качестве материала проволоки может использоваться сталь или композиционный материал. Диаметр проволоки проволочного анкера определяется расчетами и может находиться в пределах 6÷20 см. В качестве материла конического наконечника можно использовать композиционный материал, например высокопрочный бетон. Проволока проволочного анкера проходит через внутреннюю цилиндрическую полость сваи, залитую композиционным материалом, часть проволоки проволочного анкера от конического наконечника до основания сваи, длиной

, находится в изоляторе. Внутри изолятора для снижения трения, можно предусмотреть смазку для проволоки.where h is the length of the pile anchor;

- distance from the end of the pile anchor to the conical tip. The wire of the wire anchor passes through the internal cylindrical cavity of the pile and is poured after the installation of the combined anchor with a composite material. As a composite material, you can use high-strength concrete or other material that will provide strong adhesion of the wire to the pile. Magnitude

- the distance from the end of the pile anchor to the conical tip is calculated, is determined by the analytical dependencies and depends on the physico-mechanical characteristics of the soil. Steel or composite material can be used as wire material. The wire diameter of the wire anchor is determined by calculations and can be in the range of 6 ÷ 20 cm. Composite material, such as high-strength concrete, can be used as a material for the conical tip. Wire anchor wire passes through the internal cylindrical cavity of the pile, filled with composite material, part of the wire wire anchor from the conical tip to the base of the pile, length

, is in an insulator. Inside the insulator to reduce friction, it is possible to provide a lubricant for the wire.

The utility model is illustrated in the drawing: in FIG. 1 shows a cross-section of anchor-anchor foundation in the working position set to the required depth; in fig. 2 shows node A, FIG. one; in fig. 3 shows a support-anchor foundation with two combined piles, top view; in fig. 4 shows a support-anchor foundation with four combined piles, top view.

- the distance from the end of the pile 2 to the conical tip 4. The internal cavity of the pile 2 is filled with composite material 5. The top of the pile 2 is joined by a grillage 6. Part of the wire 3 of the wire anchor from the conical tip 4 to the base of the pile 2 long

located in prison 7.

Support-anchor foundation works as follows. In accordance with the technology developed by us, the combined anchor is set to the required depth in accordance with the calculations made (Fig. 1). So pile 2 is a very effective structure when working on load-bearing loads as a supporting structure, transferring force from the structure to the ground 1 of the base. The performance of the pile 2 is significantly less when working on pulling force when working as an anchor. When pulling out the shifted, combined anchor, the wire anchor joins the work: wire 3 with a conical tip 4 and has a large bearing capacity. The upper part of the piles 2 is joined by a grillage 6. The number of combined anchors in the support-anchor foundation is more than two, and this design effectively works on the effect of external bending loads (Fig. 3, 4).

. Часть проволоки 3 проволочного анкера от конического наконечника 4 до основания сваи 2 длиной

находится в изоляторе 7. Изолятор 7 позволяет приводить часть проволоки 3 при установке комбинированного анкера в предварительно напряженное состояние, не нарушая ее (фиг. 2).Thus, the support-anchor foundation will work effectively on all loads directed both horizontally and vertically: up and down. The wire 3 passing inside the cylindrical cavity of the pile 2 is rigidly fixed with the help of a composite material 5. High-strength concrete can be used as a composite material 5. The bearing capacity of the support-anchor foundation, as a supporting structure, depends largely on the pile length h. The bearing capacity of the support-anchor foundation for pulling efforts depends largely on the depth of penetration of the conical tip 4, that is, on the value

. Part of the wire 3 wire anchor from the conical tip 4 to the base of the pile 2 long

is located in the insulator 7. Insulator 7 allows you to bring part of the wire 3 when installing the combined anchor in a pre-stressed state, without breaking it (Fig. 2).

The proposed device is a two-way engineering structure more efficient and more economical than its counterparts. The proposed technical solution can be used in many sectors of the national economy, including the installation of high-voltage pylons and other structures exposed to strong wind loads.
