Abstract

The present invention discloses a construction method for mounting a layer-divided sinking apparatus in a deep compressible soil layer. The construction method comprises the following steps: 1) carrying out pre-boring of a borehole and burying a protection casing; 2) carrying out slip casting to a lower segment of the borehole to form the lower segment into a short pile reinforced body; 3) pulling up the protection casing after completing the slip casting and mounting a layer-divided sinking apparatus in the borehole where the short pile reinforced body is formed; 4) after complete mounting, correcting the reading of the layer-divided sinking apparatus, and starting filling construction and observation three days later. The construction method provided by the present invention overcomes the limitation that a layer-divided sinking apparatus must be placed on shallow bedrock at present, and allows mounting of a layer-divided sinking apparatus in a deep medium compressible or low compressible soil layer; the construction method is capable of solving the problem of distortion of an observation result of the layer-divided sinking apparatus caused by additional settlement due to dead weight of the apparatus; thus, real and efficient observation data can also be obtained when the layer-divided sinking apparatus is used in the deep medium compressible or low compressible soil layer.

Description

technical field

[0001] The invention relates to the technical field of building construction, in particular to a construction method for installing layered settlement instruments in deep compressive soil layers. Background technique

[0002] The layered settlement meter is a foundation test instrument, which is suitable for measuring the settlement of each layer under the foundation, foundation pit, embankment, etc. According to the test data changes, the settlement trend can be calculated, its stability can be analyzed, and the construction process can be monitored. Used in conjunction with a high-precision borehole inclinometer, it is an ideal equipment for in-situ monitoring of the foundation.

[0003] The layered settlement instrument widely used in foundation soil layered settlement monitoring is a precision sensing device that uses the principle of electromagnetic induction to measure the displacement of rock and soil mass. It can be pre-buried through drilling and ca...
