Description
Technical Field
The invention relates to a tunnel concrete pouring positioning device, in particular to a tunnel secondary lining drain pipe accurate positioning device, and belongs to the field of road and bridge construction.
Background
Along with the continuous improvement of the grade of national infrastructure, the construction quality requirements for road and bridge construction enterprises are higher and higher, and particularly, the quality requirements for the drainage pipe in the tunnel are higher, so that the accuracy of the high positioning of the outlet of the drainage pipe is maintained, the accuracy of the longitudinal length distance of the drainage pipe is also maintained, and the later operation maintenance of the tunnel is facilitated. At present, when a tunnel is lined, the mouth of a drain pipe is wrapped by cloth or plastic, then an electric drill is used for drilling holes on a template, an iron wire penetrates through the holes to fixedly bind the mouth of the drain pipe on the template, and then concrete casting is carried out. According to the method, the drain pipe is not firmly fixed, the pipe orifice of the drain pipe cannot be tightly fixed with the template, the phenomena of shifting and slurry feeding easily occur when concrete is poured, and the pipe orifice of the drain pipe is blocked by slurry feeding when the concrete is serious, so that accumulated water in secondary lining concrete cannot be smoothly discharged into a ditch, and potential safety hazards are left for later operation; meanwhile, as the construction space in the tunnel is too small, the difficulty is high when the template is drilled, and the construction progress is influenced; the other method is to cut holes on the side surface of the template corresponding to the drain pipe by oxygen, then pass the drain pipe through the holes of the template to fix the drain pipe, and then densify the periphery of the drain pipe and the template plug by cloth strips to prevent concrete slurry from leaking and blocking and influence the construction quality of concrete. The method has the defect that the method is difficult to separate from the template, cloth strips and concrete around the drain pipe are cleaned after the template is separated, and the construction cost is increased. At present, an ideal accurate positioning device for a tunnel secondary lining drain pipe is not disclosed and reported.
Disclosure of Invention
The invention aims to solve the problem existing in the prior art when the two lining drain pipes of the tunnel are fixed. Thereby discloses a precise positioning device for a tunnel secondary lining drain pipe.
The technical scheme of the invention is as follows:
the lower part of the template is communicated with and embedded with an electromagnetic absorber, an electromagnetic wire and an electromagnetic switch are connected between the lower part of the template and the electromagnetic absorber, an adsorption plate is placed on the outer side of the electromagnetic absorber, an inner ring of the adsorption plate is fixed with a conical positioning pipe, an outer ring of the adsorption plate is fixed with a drainage sleeve, a sealing ring is embedded in the drainage sleeve, and the end head of the drainage pipe is tightly embedded between the drainage sleeve and the conical positioning pipe.
Further according to the actual number of drain pipes that needs in tunnel, can set up and seal a plurality of drain pipes of location range simultaneously.
The invention has reasonable design structure, quick and flexible installation, convenient operation and maintenance, stable and reliable performance, high safety performance, reliable quality and high repeated use rate by adopting the low-voltage electromagnetic super absorber, saves the construction cost, and can seal and position a plurality of drain pipes according to the number of the drain pipes actually required by the tunnel, thereby being a tunnel secondary lining drain pipe accurate positioning device meeting the safety quality requirement.

Fig. 1 is a schematic diagram of the front view structure of the present invention.
FIG. 2 is a schematic view of the cross-sectional structure of FIG. 1 taken along the direction A-A in accordance with the present invention.
The reference numerals are as follows: the concrete-filled type concrete-filled building block comprises a template 1, an electromagnetic absorber 2, an adsorption plate 3, electromagnetic wires 4, a piezoelectric box 5, an electromagnetic switch 6, a conical positioning pipe 7, a sealing ring 8, a drainage sleeve 9, a drainage pipe 10 and concrete 11.
Detailed Description
The invention is described in further detail below with reference to examples and figures:
the embodiment of the invention is provided with two drain pipes which are arranged in a sealing and positioning way at the same time, a piezoelectric box 5 is fixed at the inner side of the upper part of a template 1, an electromagnetic absorber 2 is penetrated and embedded at the lower part of the template 1, an electromagnetic wire 4 and an electromagnetic switch 6 are connected between the piezoelectric box 5 and the electromagnetic absorber 2, an adsorption plate 3 is placed at the outer side of the electromagnetic absorber 2, a conical positioning pipe 7 is fixed at the inner ring of the adsorption plate 3, a drain sleeve 9 is fixed at the outer ring of the adsorption plate 3, a sealing ring 8 is embedded in the drain sleeve 9, and the end head of a drain pipe 10 is tightly embedded between the drain sleeve 9 and the conical positioning pipe 7.
When the invention is operated, the piezoelectric box and the electromagnetic switch are started, the electromagnetic absorber generates electromagnetic force, so that the adsorption plate connecting the drainage sleeve and the conical positioning pipe is tightly absorbed by the electromagnetic absorber, concrete is poured at the moment, the concrete can not enter the drainage pipe in the whole process of the second lining, the accurate positioning of the drainage pipe in space can be ensured, the electromagnetic switch is closed after the concrete is solidified, the template and the electromagnetic absorber are removed, the adsorption plate, the drainage sleeve and the conical positioning pipe are taken out together, the drainage pipe orifice is exposed, the accurate positioning of the second lining drainage pipe is completed, and the pushing is reused.
