Description
Technical Field
The utility model relates to the technical field of subway construction, in particular to a shield interval duct piece staggering measuring instrument.
Background
Along with the development of the society, at present, in order to solve the problem of traffic jam, more and more cities build subways. In order to reduce the influence on urban traffic operation during construction and accelerate the construction progress, most tunnel construction adopts a shield method for construction. In the shield tunneling process, disturbance is inevitably caused to surrounding strata, and if grouting is not carried out timely, a wrong platform phenomenon can be caused. The dislocation can lead to the section of jurisdiction damaged, tunnel interval structure infringes the limit, also can produce adverse effect to durability, waterproof nature of tunnel interval structure.
The conventional duct piece dislocation measuring instrument generally uses a straight ruler, but can accurately read only by matching with other instruments, the efficiency is low, and when the straight ruler and other instruments are used for measuring dislocation, only one measured point data can be obtained each time, so that the problems of slow efficiency, low data precision and the like are solved, and therefore, the utility model is necessary for conveniently, accurately and effectively inventing the dislocation measuring instrument.
SUMMERY OF THE UTILITY MODEL
Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides the measuring instrument for the duct piece dislocation of the shield interval, which effectively solves the problem that no convenient instrument can rapidly and accurately measure the dislocation amount in the shield tunneling process.
The technical scheme for solving the problem is that the vertical plate comprises a vertical plate, wherein the upper side edge of the vertical plate is horizontal, the lower side edge of the vertical plate is in an arc shape with an upward opening, a fan-shaped plate with an upward tip end is arranged on the front side of the vertical plate, the fan-shaped plate can move up and down along the vertical plate, the round edge of the fan-shaped plate is arranged below, and the radius of the lower side edge of the vertical plate is equal to that of the fan-shaped plate; the front sides of the left end and the right end of the vertical plate are fixed with a strip plate, the sides of the left side and the right side of the arc plate are respectively provided with a U-shaped plate in a buckling mode, a pressure spring is connected between the U-shaped plate and the strip plate positioned on the same side of the U-shaped plate, and the U-shaped plate and the fan-shaped plate can not be separated by the pressure spring; the sector plate is marked with scale marks.
Preferably, a triangular pressing plate is fixed on the rear side of the lower end of the vertical plate.
Preferably, a handle is fixed at the upper end of the sector plate.
Preferably, the graduation mark is in an arc shape concentric with the sector plate.
The utility model has the advantages of ingenious structure, convenient carrying, simple structure and low cost, can quickly, accurately and effectively measure the dislocation quantity, and is extremely suitable for the field construction environment.

FIG. 2 is a top cross-sectional view of the present invention.
Detailed Description
The following description will explain embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 2, the utility model comprises a vertical plate 1, wherein the upper side edge of the vertical plate 1 is horizontal, the lower side edge of the vertical plate 1 is arc-shaped with an upward opening, a fan-shaped plate 2 with an upward tip is arranged at the front side of the vertical plate 1, the fan-shaped plate 2 can move up and down along the vertical plate 1, the circular edge of the fan-shaped plate 2 is below, and the radius of the lower side edge of the vertical plate 1 is equal to that of the fan-shaped plate 2; the front sides of the left end and the right end of the vertical plate 1 are fixedly provided with a strip plate 3, the sides of the left side and the right side of the arc plate are respectively provided with a U-shaped plate 4 in a buckling mode, a plurality of pressure springs are connected between the U-shaped plate 4 and the strip plate 3 which is positioned on the same side of the U-shaped plate 4, and the U-shaped plate 4 can not be separated from the fan-shaped plate 2 due to the pressure springs; the sector plate 2 is marked with scale marks.
For convenient use, a triangular pressing plate 5 is fixed on the rear side of the lower end of the vertical plate 1.
For convenient use, a handle 6 is fixed at the upper end of the sector plate 2.
The scale marks are in an arc shape concentric with the sector plate 2.
It is worth noting that the two U-shaped plates 4 make the sector-shaped plate 2 parallel to the vertical plate 1.
When the device is used, the vertical plate 1 in the device is placed on the side of the pipe piece with the higher dislocation position, then one hand presses the pressing plate 5, so that the vertical plate 1 is fixed, the other hand holds the handle 6 to be flat and presses downwards, the arc-shaped side edge at the lower end of the sector plate 2 is attached to the surface of the other pipe piece, the scales on the sector plate 2 are directly read, and the dislocation numerical value in the contact range of the sector plate 2 is obtained. When two sections of pipe of dislocation department are not concentric, but sector plate 2 horizontal hunting adjusting position to come the position and the angle of adjusting sector plate 2 temporarily according to the section of pipe position of dislocation below, the accurate wrong platform data that obtains the measurement.
The method can be operated by one person, all the dislocation values in the range of the conical measuring scale can be obtained each time, the efficiency is high, the precision is high, and dislocation data can be accurately and effectively obtained.
The utility model has the advantages of ingenious structure, convenient carrying, simple structure and low cost, can quickly, accurately and effectively measure the dislocation quantity, and is extremely suitable for the field construction environment.
