Embodiment approach

[0045] As a preferred embodiment of the present invention constructed on the independent foundation of the bearing layer, the main structure 20 includes:

[0046] The cushion layer 21 poured in the overexcavated foundation pit, the backfill space is formed between the surrounding side walls of the cushion layer 21 and the corresponding inner wall of the overexcavated foundation pit; and

[0047] For the base layer 22 poured on the cushion layer 21 , the bottom area of ​​the base layer 22 is smaller than the top area of ​​the cushion layer 21 . By arranging the cushion layer 21, the part where the excavated foundation pit exceeds the height of the foundation layer 22 is compensated, and the thickness of the cushion layer 21 is determined according to the height of the excavated foundation pit exceeding the foundation layer 22. Solved the problem of excessive excavation when excavating the foundation pit.

[0048] After the bearing layer 10 is excavated to form an overexcavatio...

Abstract

The invention relates to an independent foundation constructed on a bearing layer and a construction method thereof, wherein the independent foundation comprises: a main structure poured in an overexcavated foundation pit, and a gap between the surrounding side walls of the main structure and the corresponding inner side walls of the overexcavated foundation pit A space for backfilling is reserved; a plurality of pads arranged on the top surface of the main structure and located at the corresponding edges; The top surface of the pad is flush; the backfill layer filled in the backfill space and the top surface is flush with the top surface of the pad; multiple support beams for supporting the floor, and the opposite ends of the support beams are supported on the pad and the pad. Corresponding leveling blocks. Using the top surface of the pad as a reference standard, the leveling pad is formed by cast-in-place, so that the support beam can be set horizontally, which makes up for the lack of a certain level of the ground around the overexcavation foundation pit affected by the excavation. Support the floor with support beams.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an independent foundation constructed on a bearing layer and a construction method thereof. Background technique [0002] When the upper structure of a building adopts a frame structure or a single-story bent structure for load-bearing, its foundation often adopts an independent foundation in the form of a square or a circle. The independent foundation is located on the bearing layer, which is generally moderately weathered or strongly weathered rock formation, and the excavation depth of the rock layer is not easy to control. Excavating a large piece of rock will often bring up a large piece of rock, resulting in over-excavation phenomenon. When over-excavation occurs, the floor on the backfill layer around the independent foundation constructed on the bearing layer is prone to subsidence. Contents of the invention [0003] The purpose of the present invention is to overc...
