Description

TECHNICAL FIELD

[0002] In the reinforcing and repairing construction of existing building foundation, the common reinforcing method is to reinforce the foundation by grouting, and if necessary, anchor rod or micro pile is punched into the foundation to reinforce the foundation, so as to strengthen the rigidity and integrity of the foundation. When grouting reinforcing construction is carried out, holes are drilled at the original foundation cracks, grouting pipes are inserted, and then the slurry is injected into the cracks or damaged parts of the foundation by pressure grouting, so that the slurry diffuses, solidifies and adheres in the cracks, so as to restore the integrity of the component; when anchor rod or micro pile reinforcing construction is carried out, anchor rod machine or pile driver is used to punch anchor rod or micro pile into the foundation below and anchor into the foundation, and then the foundation is poured into a whole, so as to improve the integrity of the foundation and improve the bearing capacity of the foundation.

[0003] The disadvantages of the prior art are that the grouting reinforcing requires high control of grouting pressure, and when the pressure is insufficient, the foundation cracks cannot be filled, and when the pressure is too high, the foundation cracks are enlarged, and the grouting material is wasted; anchor rod or micro pile reinforcing construction requires large equipment such as anchor rod machine or pile driver to enter the site for construction, which requires high site and space, and large equipment cannot enter the indoor or limited area for construction.

[0004] To solve the problem that large equipment cannot enter the indoor construction when reinforcing and repairing construction is carried out on building foundation, and to solve the problem that the use of building is not affected during construction, a building indoor foundation reinforcing structure is provided.

[0005] The technical scheme adopted by the utility model to achieve the object of the application is as follows: a building indoor foundation reinforcing structure, comprising a concrete ground surface.

[0006] The foundation reinforcing structure comprises a reinforcing sleeve, a connecting steel reinforcement cage and a reinforced ground concrete layer.

[0007] The reinforcing sleeve is arranged in the building indoor foundation through the concrete ground surface, and the upper end of the reinforcing sleeve is exposed above the concrete ground surface.

[0008] The connecting steel reinforcement cage is fixedly connected with the part of the reinforcing sleeve (1) exposed above the concrete ground surface.

[0009] The connecting steel reinforcement cage is arranged in the reinforced ground concrete layer, and the reinforced ground concrete layer is arranged above the concrete ground surface.

[0018] Referring to the drawings, a building indoor foundation reinforcing structure, including concrete ground surface, the foundation reinforcing structure includes: reinforced sleeve pipe 1, connecting steel reinforcement cage 2 and reinforced ground concrete layer 3.

[0019] The reinforced sleeve pipe 1 is arranged in the building indoor foundation through the concrete ground surface 4, and the upper end of the reinforced sleeve pipe 1 is arranged on the concrete ground surface 4.

[0020] The connecting steel reinforcement cage 2 is fixedly connected with the part of the reinforced sleeve pipe 1 exposed on the concrete ground surface 4.

[0021] The connecting steel reinforcement cage 2 is arranged in the reinforced ground concrete layer 3, and the reinforced ground concrete layer 3 is arranged on the concrete ground surface 4.

[0023] The reinforced sleeve pipe 1, the concrete ground 4, the concrete support column 5, the reinforced sleeve pipe 1 and the connecting steel reinforcement cage 2 are integrally formed.

[0024] In the embodiment of the utility model, firstly, based on the geological and building conditions under the concrete ground 4, the basic data such as the setting number, position, length and diameter of the reinforced sleeve pipe 1 are determined.

[0025] The construction steps are as follows: ① a foundation hole is opened in the concrete ground 4, and the soil near the foundation hole is excavated.

[0026] ② the support frame 7-1 is fixedly connected with the concrete ground 4 through the fixing bolt 7-3 to form an integrated whole.
