Problems solved by technology

[0003] Traditional reinforcement methods include the method of pasting fiber composite materials and enlarging the cross-section. However, for the reinforcement of concrete substation structures, the above-mentioned traditional methods have some shortcomings. For example, the method of pasting fiber composite materials uses structural glue for pasting. It is easy to damage and fail in the outdoor environment; the reinforcement construction period of the enlarged cross-section method is long, and it requires long-term power outages in the substation, causing a large amount of economic losses, and is not applicable
[0004] At present, there is still a lack of implementation methods for concrete substation frame reinforcement

Embodiment approach

[0043] Such as figure 1 As shown, the method for implementing the winding fiber bundle yarn of the present invention to strengthen the concrete transformer structure comprises the following steps:

[0044] 1) Surface treatment is carried out on the surface area of ​​the concrete substation frame 1 to be reinforced, and only the new structural surface is exposed. When strengthening the column foot, the covering soil should be excavated first to expose the original basic structure;

[0045] 2) Positioning anchor bolts 2 and steering hooks 3 are arranged on the upper and lower edges of the area to be reinforced. If the length of the upper and lower edges is greater than 50cm, one or more anchor bolts 2-1 can be added in the middle of the reinforcement area as appropriate;

[0046] 3) Winding the fiber bundle yarns 4-1 and 4-2 onto the positioning pin 2 in an alternate vertical and horizontal manner;

[0047] 4) A steel formwork 5 is set on the periphery of the reinforcement area...

Abstract

An implementing method for reinforcing a concrete transformation frame by winding fiber bundle yarns includes the steps of: 1) performing surface treatment on a surface area of a concrete transformation frame to be reinforced to expose a new structure surface, and excavating earth to expose an original base structure during reinforce of a column foot; 2) arranging positioning anchor bolts and turning hooks on the upper edge and the lower edge of an area of the frame to be reinforced, wherein when the lengths of the upper edge and the lower edge are greater than 50 cm, one or more anchor bolts are arranged in the central section; 3) winding fiber bundle yarns onto the positioning anchor bolts according to a crisscross method; 4) arranging steel moulding plates on the outer periphery of the area to be reinforced, and sealing the bottoms of the steel moulding plates with an expediting setting filling material; 5) pouring resin into gaps between the steel moulding plates and the frame to be reinforced, wherein the resin is poured into the tops of the steel moulding plates; and 6) removing the steel moulding plates after resin curing. The implementing method is simple in process, can be directly operated in a reinforce site and achieve direct forming, achieve effective fitting of a reinforced structure, and can be applied to a component with different surface situations; and the implementing method is wide in application range, and can effectively reinforce the transformation frame and improve the anti-seismic property of the transformation frame.

Description

technical field [0001] The invention relates to an on-site reinforcement structure method for a concrete substation frame, in particular to a method for reinforcing the concrete substation frame by on-site winding of fiber bundle yarns. Background technique [0002] At present, the substation structure is mostly reinforced concrete structure. Due to the durability of concrete, the technical level and construction quality of the year, the concrete structure of the substation generally suffers from aging and deterioration to varying degrees. If these problems cannot be dealt with in time and properly, it will seriously affect the reliability, safety and service life of the structure, and even endanger the safe operation of the power grid. Power facilities such as reinforced concrete structures in substations are "lifeline" projects that are related to social development and stability. If they are demolished, the cost and impact will be relatively large, so their reinforcement ...
