Construction method and structure of foundation cushion under condition of current-formed silt soil

Abstract

The invention relates to a construction method of a foundation cushion under the condition of current-formed silt soil. The construction method includes the following steps that a pile foundation is piled in an area to be constructed, and a soil body around the pile foundation is excavated to form a foundation pit and a part of the pile foundation is exposed; concrete is poured at the bottom of the pile foundation to form a bearing platform cushion; and after the bearing platform cushion reaches set strength, formworks are erected around an area in which a bearing platform is to be constructedon the bearing platform cushion, and pouring is performed on the outer sides of the formworks to form a floor cushion to form a construction space for the construction of the bearing platform at theposition, corresponding to the pile foundation, of the floor cushion. According to the construction method of the foundation cushion under the condition of the current-formed silt soil, the problem ofdifficulty in construction on the current-formed silt soil is effectively solved. The floor cushion is formed by construction and then the bearing platform is constructed to speed up the construction, the soil body is prevented from collapsing, and the overall strength of the foundation cushion can be further strengthened to ensure the quality of subsequent construction.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method and structure of a foundation cushion under the condition of flow-plastic silt soil. Background technique [0002] The cushion is the middle layer between the reinforced concrete foundation and the foundation soil. Its function is to make the surface of the soil flat so that the steel bars can be tied on it, and it also plays a role in protecting the foundation. The general construction method is to use plain concrete to form a cushion cushion Finally, the cap at the top of the pile foundation is constructed, and then poured to form the bottom slab cushion and the bottom slab. However, in actual construction, the soil may be flow-plastic silt soil, which has low bearing capacity, high moisture content, and sensitive High, if this method is used, the long construction time is not conducive to the stability of the soil, so it is difficult to construct on t...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of the prior art, to provide a construction method and structure of the foundation cushion under the condition of flow-plastic silt soil, to solve the difficult problem of construction on the flow-plastic silt soil, and to form a The cap is constructed after the floor cushion to speed up the construction and prevent the soil from collapsing. It can also strengthen the overall strength of the foundation cushion and ensure the quality of subsequent construction.
