Abstract

The utility model discloses a protection device for a strain gauge on a steel sheet pile, which comprises soil discharging boots and a protective cover, wherein the soil discharging boots are arranged on the steel sheet pile body and positioned below the position of a plumb in the center of the strain gauge; the protective cover is arranged on the steel sheet pile body and is covered on the strain gauge; the soil discharging boots are formed by combining a casing with a semi-cylindrical upper part and a casing with a semi-conical lower part; and the protective cover is a rectangular frame body, and mounting holes are formed at the two sides of the frame body. The utility model can penetrate the mscellaneous fill layer with thickness of 3 m on the land area or water area project along with the steel sheet pile body, and can penetrate the soft foundation soil layer with penetration resistance (9MPa) and standard penetration resistance N63.5 (blow count 15), the entry depth reaches 30m, and the utility model is suitable for the steel sheet piles with various enclosing construction structures.

Description

The protective device of strain meter on the steel sheet pile
Technical field
The utility model relates to goes along with sb. to guard him steel sheet pile pile body technology for deformation monitoring field, the protective device of strain meter on specifically a kind of steel sheet pile.
Background technology
In work progress, the diverse location of going along with sb. to guard him the steel plate pile body for Validity Test is subjected under the effect of external force, deform, the STRESS VARIATION situation during relative displacement, usually distortional stress test strain meter is set going along with sb. to guard him on the steel plate pile body, because it is external that the installation of distortional stress test strain meter is exposed to steel sheet pile, insert in the soil body process at steel sheet pile, be subjected to the influence of engineering geological conditions, ambient conditions and soil body frictional resistance, damage easily, cause distortional stress test strain meter can't carry out operate as normal.
Summary of the invention
The purpose of this utility model is the protective device of strain meter on a kind of steel sheet pile that provides at the deficiencies in the prior art, and it can guarantee that distortional stress test strain meter is in normal operating conditions all the time, has improved the accuracy of test.
The concrete technical scheme that realizes the utility model purpose is:
The protective device of strain meter on a kind of steel sheet pile, it comprises casting boots and protective cover, the casting boots are located on the steel sheet pile pile body and are positioned at below, plumb position, strain meter center; Protective cover is located on the steel sheet pile pile body and is covered in strain meter; The casting boots are that semi-cylindrical shells, bottom form for the half cone-shaped shell combination by top; Protective cover is a rectangle framework, and the framework both sides are provided with installing hole.
The utility model can be applicable on land-based area or the water areas project, use confirmation through overtesting with on multinomial engineering, strain meter can pass through the thick miscellaneous fill layer of 3m with the steel plate pile body, pass through in the subgrade soil layer that specific penetration resistance 9MPa and standard injection N63.5 (hitting number) 15 hit, insert the native degree of depth and reach 30m, guaranteed that the stress test sensor can be in normal operating conditions; The utility model is applicable on the steel sheet pile of all kinds of space enclosing structures.

Fig. 2 is Fig. 1 lateral view
Fig. 3 is Figure 1A--the A view
The specific embodiment
Consult Fig. 1, Fig. 2 and Fig. 3, the utility model comprises casting boots 3 and protective cover 4, and casting boots 3 are located on the steel sheet pile pile body and are positioned at below, plumb position, strain meter center; Protective cover 4 is located on the steel sheet pile pile body and is covered in strain meter; Casting boots 3 are that semi-cylindrical shells 31, bottom are that half cone-shaped housing 32 combines by top; Protective cover 4 is a rectangle framework, and the framework both sides are provided with installing hole.
The utility model is work like this: the technical requirements according to detecting, several strain meters 2 are set on the pile body of steel sheet pile 1, and corresponding to each below, strain meter 2 plumb positions casting boots 3 are set; Then protective cover 4 is covered on strain meter 2 directly over; When steel sheet pile 1 inserts in the soil body process; under the guiding function of casting boots 3; the soil body is squeezed out a narrow space, reduce the soil body frictional resistance that acts on strain meter 2, thereby protection strain meter 2 remains normal operating conditions in steel sheet pile 1 insertion soil body process.
