Description

Punching-free embedded CP III embedded part mark

Technical Field

The utility model relates to the field of track construction equipment, in particular to a punching-free embedded CP III embedded part mark.

Background

At present, a subway shield tunnel needs to carry out track control network (CP III) measurement before track laying operation, and CP III measurement marks adopt a mode of drilling and embedding on shield segments, and the embedding mode has the following defects:

1. the labor investment is large, and each group needs 5-6 people;

2. the equipment investment is high, and each group needs equipment such as a generator and a percussion drill;

3. the embedding work efficiency is low, and at most 1.5-2 km tunnels can be embedded in each group one day;

4. drilling can permanently damage the structure of the tube sheet;

5. when drilling, the reinforcing steel bars in the pipe piece can be easily drilled.

Therefore, it is necessary to design a hole-free embedded CP iii embedded mark to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a punching-free embedded CP III embedded part mark.

The purpose of the utility model is realized by the following technical scheme:

the utility model provides a exempt from to punch and bury formula CP III and bury a mark, includes the body, the body sets up in shield constructs the section of jurisdiction upper band internal screw thread slip casting hole, the body include the fixed part, with assembly and disassembly tools complex first installation department, the fixed part be provided with the external screw thread that the internal thread matches, first installation department with fixed part fixed connection, first installation department center runs through and is provided with the pilot hole that is used for assembling prism subassembly.

Preferably, the first installation part is an inner hexagonal nut, and the disassembling tool is an inner hexagonal wrench.

Preferably, still be supporting with dedicated dismouting middleware, the dismouting middleware is used for cooperating the assembly and disassembly tools installation the body, the one side of dismouting middleware is provided with perpendicularly and is no less than a mounting bar, the another side of dismouting middleware be provided with assembly and disassembly tools complex second installation department, first installation department be provided with the mounting hole that the mounting bar matches.

Preferably, the second installation part is an inner hexagonal nut, and the disassembling tool is an inner hexagonal wrench.

In summary, the utility model includes at least one of the following beneficial technical effects:

1) the investment of labor force and equipment is reduced, and meanwhile, the working efficiency is improved;

2) the permanent damage to the structure of the segment joint in the drilling operation is avoided, and the steel bars drilled into the segment in the drilling operation are also avoided;

3) through adopting dedicated dismouting middleware cooperation assembly and disassembly tools to carry out the dismouting to CP III embedded part sign, when not holding the personnel of dismouting middleware on the spot, just can't carry out the dismouting to CP III embedded part sign, played the effect of theftproof.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution:

as shown in fig. 1 and 2, a free-punching embedded CP iii embedded part mark comprises a body 1, as shown in fig. 3 and 4, the mark is further provided with a special dismounting intermediate part 2, the body 1 is installed on a shield segment through the dismounting intermediate part 2 in cooperation with an allen key and is fixedly arranged in a grouting hole with internal threads, the body 1 comprises a fixing part 11 and a first installation part 12, the center of the first installation part 12 is provided with an assembling hole 13 for assembling a prism assembly and two installation holes 14 which are symmetrical about the center through, the fixing part 11 is provided with external threads matched with the internal threads, and the first installation part 12 is fixedly connected with the fixing part 11.

With reference to fig. 4, one surface of the dismounting intermediate member 2 is vertically provided with a mounting bar 21 matched with the mounting hole 14, and with reference to fig. 3, the other surface of the dismounting intermediate member 2 is provided with a second mounting portion 22 matched with the allen key, and the second mounting portion 22 is an inner hexagon nut.

The working principle is as follows:

according to the structural feature of subway shield section of jurisdiction, utilize original injected hole (section of jurisdiction is no longer used after the installation) on the section of jurisdiction, insert the mounting bar 21 of dedicated dismouting middleware 2 in mounting hole 14, adopt interior hexagonal to twist dismouting middleware 2 again, the fixed part that CP III buried a sign is twisted into the injected hole, scribble quick-drying glue on the external screw thread of fixed part 11 during the installation, the sign can not become flexible after having installed, do not lead to the fact any influence to the section of jurisdiction structure, CP III buried a sign fixed back alright assemble CP III related components such as prism in pilot hole 13.

The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the utility model is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art.
