Embodiment Construction

[0026] The core of the present invention is to provide a mattress layer, which solves the problem of single function of the existing mattress layer.

[0027] The present invention also provides a composite foundation comprising the above-mentioned mattress layer, which fully exerts the joint bearing capacity of piles and soil.

[0028] The invention also provides a construction method for forming the above-mentioned composite foundation.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

Abstract

The invention discloses a mattress layer. The mattress layer comprises a rigid mattress layer body and a soft mattress layer body located above the rigid mattress layer body. Due to the fact that the mattress layer comprises the rigid mattress layer body and the soft mattress layer body, composite foundation pile soil is integrated through the lower rigid mattress layer body, the joint bearing capacity of the pile soil can be brought into better play, rigid contact between a reinforced concrete foundation and pile bodies and rigid contact between the reinforced concrete foundation and the rigid mattress layer body can be avoided through the upper soft mattress layer body, a composite foundation has the better buffering and vibration absorption effect, and deformation compatibility of the composite foundation pile soil can be ensured through the soft mattress layer body. Meanwhile, a hydraulic channel can be formed through the soft mattress layer body, so that the composite foundation is softened, the rigid mattress layer body can seal the hydraulic channel, and accumulated water is prevented from permeating the soil among piles. Therefore, the problem that an existing mattress layer is single in function is solved. The invention further discloses the composite foundation comprising the mattress layer and a construction method of forming the composite foundation.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a cushion layer. It also relates to a composite foundation comprising the above mattress layer. At the same time, it also relates to a construction method for forming the composite foundation. Background technique [0002] The cushion layer is the cushion layer arranged on the top of the pile body of the pile-soil composite foundation, which mainly plays the role of adjusting the load sharing of the pile-soil, reducing the stress concentration on the bottom surface of the foundation, and coordinating the deformation of the pile-soil. [0003] Existing mattress generally only adopts crushed stone or lime soil mattress, i.e. flexible mattress; or only adopts plain concrete mattress, i.e. rigid mattress. In some cases, only the flexible cushion layer cannot exert the bearing capacity of the pile body in advance, and the rigid cushion layer cannot coordinate the defor...
