Abstract

The invention relates to a comprehensive frictional resistance meter which comprises a protective cover, a fixed panel, a stressed panel, a guide rail, a first backup plate, a second backup plate, a stress detector and a flexible soil pressure gauge, wherein the protective cover is provided with a receiving space; the fixed panel is formed at a second baffle of the protective box; the stressed panel faces the fixed panel; the guide rail is provided with a guide rail sliding locking groove and is arranged at one side of the stressed panel, which is close to the receiving space in parallel; the first backup plate is arranged between the fixed panel and the guide rail; the second backup plate is arranged in parallel to the first backup plate and located between the fixed panel and the guide rail; the stress detector is provided with a first lead and is arranged between the first and second backup plates; and the flexible soil pressure gauge is provided with a second lead and arranged at one side of the stressed panel different from the guide rail. The comprehensive frictional resistance meter is suitable for actual engineering monitoring, not only the monitoring work is less affected by construction, and the precision is higher, but also the survival rate of the comprehensive frictional resistance meter is considerably high, and the comprehensive frictional resistance meter has higher test precision and stronger adaptability.

Description

technical field [0001] The invention relates to the technical field of testing devices used in construction engineering, in particular to a comprehensive frictional resistance meter for caisson lateral earth pressure and frictional resistance. Background technique [0002] A well-shaped structure made of reinforced concrete on the ground in advance is used as the support of the underground structure. Under the protection of the well wall, the soil is dug in the well by machinery and manpower, and the structure sinks into the soil under its own weight. called caissons. Therefore, the sinking of the caisson is essentially a construction process in which a structure that has been made in advance on the ground is sunk to a certain depth underground through excavation to become an underground structure. The sinking of the caisson is accomplished by overcoming the frictional resistance between the well wall and the soil and the counterforce of the blade foot under the action of i...
