Embodiment Construction

[0011] The layered settlement observation method of high fill soil adopts the following steps: a. When the first step observation point is installed at the initial elevation of backfilling, temporarily fix the cross-groove steel frame 1, and the center of the cross-groove steel frame 1 is fixed with a vertically placed The steel bar body 2, observe and record the readings through the top of the steel bar body 2 and the external reference ruler; b. Carry out layered backfilling and rolling, and each layer of backfilling is observed through the top of the steel bar body 2, and the settlement of the first observation point is recorded ; c, when the layer height of the backfill is close to the top of the reinforcement body 2, connect a reinforcement body 2 at the top of the reinforcement body 2, so that the top of the reinforcement body 2 at the top is always above the backfill soil layer; During the height of the two-step observation point, place the cross-recessed steel frame I3,...

Abstract

The invention specifically provides a method and a device for observing layered settlement of high fill earth, and aims at solving the problem that the height settlement data of the existing high fill earth cannot be observed and so that the potential risk cannot be early found out. The method comprises the steps of a, fixing a cross channel steel frame of which the center is fixed with a reinforcing steel bar body, observing the number and record; b, backfilling and rolling by layers, and recording the settlement value; c, continuously connecting when the backfilled earth reaches the top end of the reinforcing steel bar body; d, arranging the cross channel steel frame I when backfilling to reach the height of a second observing point, wherein a steel pipe body is fixed in the center of the cross channel steel frame I; recording the observing number; e, continuously backfilling rolling by layering, and recording the settlement value of each observing point; f, continuously connecting the steel pipe body when the backfilled earth reaches the top end of the steel pipe body; g, repeating steps from d to f when the earth is backfilled to reach the height of a third observing point until the backfilling and rolling are done. With the adoption of the method and the device, the layered observing of a plurality of observing points in vertical direction during backfilling can be achieved.

Description

technical field [0001] The invention relates to building construction settlement observation technology, in particular to a method and device for observing layered settlement of high fill soil. Background technique [0002] Larger settlements usually occur in high fill sites of construction projects, and there are generally problems such as long settlement process and uneven settlement, which have a great impact on the safety and stability of various engineering structures. Therefore, the settlement of the foundation soil of engineering structures , especially the monitoring of stratified subsidence characteristics is of great significance. [0003] The current method of monitoring the layered subsidence of the foundation soil is to set up observation points in the shallower part of the foundation after the backfilling of the high fill site is completed. Therefore, the compactness of the high fill soil cannot be guaranteed, the stability performance is poor, and there are p...
