A construction method of a foldable telescopic protection device for a square concrete foundation

Abstract

The invention discloses a construction method of a folding telescopic protection device for a square concrete foundation, which includes the following process steps: 1) according to the geological and hydrological conditions of the location of the square concrete foundation and the specifications and sizes of the square concrete foundation, each component of the protection device is determined 2) After transporting the protection device of the corresponding size to the work area, place the mother plates of the two enclosure members of the protection device on the two diagonal top surfaces of the square concrete foundation, and then place the protective device with the L The L-shaped side guard plate 1 and the L-shaped side guard plate 2 that are hinged to each other are turned outward and cover the upper side of the square concrete foundation, and the L-shaped upper panel covers the diagonal top surface of the square concrete foundation; the present invention can Effectively protect the foundation, can be stretched horizontally or folded vertically, and can be applied to different sizes. It not only protects the horizontal edges and corners of the upper surface of the foundation, but also protects the longitudinal edges of the foundation, which can greatly reduce the damage rate of the overall concrete foundation.

Description

technical field [0001] The invention relates to the field of concrete foundation protection, in particular to a construction method of a folding telescopic protection device for a square concrete foundation. Background technique [0002] In the existing concrete foundation construction of iron towers, a series of foundation protection measures are usually adopted such as covering the foundation surface with soil bags, covering the edges of the foundation with waste tires, using brackets welded with angle steel to protect the foundation, or using waste formwork or wooden nails as a frame. The above protective measures have no obvious effect during construction. Most of the traditional protective devices are heavy and bulky, which increases the transportation cost; especially for special areas with inconvenient transportation such as wild mountainous areas, transportation and installation have become a huge problem, and It is extremely difficult to carry and disassemble. Even ...

Problems solved by technology

The above protective measures have no obvious effect during construction. Most of the traditional protective devices are heavy and bulky, which increases the transportation cost; especially for special areas with inconvenient transportation such as wild mountainous areas, transportation and installation have become a huge problem, and It is extremely difficult to carry and disassemble. Even if it is transported by a single person, the transportation volume is very small each time, and it is not easy to work long distances; moreover, the protection range of the overall concrete foundation is not comprehensive enough, and most of the effects are not obvious during construction, and there are still foundation damages Phenomenon: The materials used have low toughness and poor flexibility, which are inconvenient to install and not easy to fit after installation. They should damage the corners of the foundation and are not easy to recycle. Easy to steal, high comprehensive project cost, difficult to control on-site construction and short service life, etc., seriously affect the quality of foundation construction
