Device and method for embedding earth pressure gauge in deep muddy soil layer

Abstract

The invention relates to an embedding device and method for soil pressure gauges in a deep silt soil layer. The embedding device comprises at least one first steel reinforcement framework section and at least one second steel reinforcement framework section, wherein the first steel reinforcement framework section is used for binding one lateral soil pressure gauge, the second steel reinforcement framework section is used for binding the vertical soil pressure gauge, and the two adjacent ends of the steel reinforcement framework sections are connected in an overlapped mode and fixed in a welded mode; each steel reinforcement framework section comprises two primary reinforcements arranged in parallel, a plurality of secondary reinforcements arranged in parallel are arranged between every two primary reinforcements, and the two ends of each secondary reinforcement are welded to the corresponding two primary reinforcements in an orthogonal mode. The embedding method comprises the five steps of construction preparation, drilling, framework welding, binding of the pressure gauges and in-hole mounting. The embedding device and method can effectively assist in embedding the soil pressure gauges and achieve accurate positioning; meanwhile, design is flexible, construction is convenient, cost is low, the vertical soil pressure gauge and the lateral soil pressure gauge can be effectively embedded in the deep silt soil layer, the number of construction procedures is reduced, building cost of projects is reduced, and normal work of the soil pressure gauges is guaranteed.

Description

technical field [0001] The invention relates to a device and method for embedding an earth pressure gauge in a deep muddy soil layer, belonging to the technical field of engineering monitoring. Background technique [0002] With the gradual economic development of my country's coastal areas, the demand for land in coastal areas has increased greatly, leading to an increasing shortage of land resources. Increasing the land use area by reclamation has become a common method used by local construction departments. However, the soil quality of coastal tidal flats is basically newly deposited under-consolidated silt, with poor engineering characteristics. During the process of land reclamation, the mechanical properties of the foundation soil change greatly, and the soil layer affected by additional stress is also deep. Therefore, it is judged that land reclamation During the process, the stability of the filling body itself and the silt soft soil layer needs to find out the vert...

However, the soil quality of coastal tidal flats is basically newly deposited under-consolidated silt, and its engineering characteristics are poor. During the process, the stability of the filling body itself and the silt soft soil layer needs to find out the vertical and lateral earth pressure changes at different depths of the silt soil layer with the filling conditions and the soil consolidation. The layout of vertical and lateral earth pressure gauges in the layer is extremely critical

The quality of earth pressure gauge burial has a great influence on the test results. At present, most literatures analyze the monitoring data processing results more, but seldom discuss the burial process and burial method. Most of them do not clearly point out the vertical and lateral directions. The specific implementation details of earth pressure gauge burial
