Description
Technical Field
The utility model belongs to the technical field of the shield constructs and measures, specifically speaking relates to a shield constructs and measures observation device.
Background
Along with the gradual deepening of the shield tunneling machine, in order to ensure that the shield tunneling machine smoothly advances along the designed axis of the tunnel until the shield tunneling machine is communicated, the ground measurement control point needs to be synchronously guided into the tunnel. However, due to various factors such as environment, light, longitudinal slope fluctuation and the like in the hole, the extension of the control point is inevitably blocked. In the prior art, the assembled and molded duct piece is used as an instrument base connecting device, but the assembled and molded duct piece has smaller radius and is not suitable for standing, so that the instrument is inconvenient and unsafe to erect, and the observation of measuring personnel is difficult.
Disclosure of Invention
In order to solve the problem that proposes among the background art, the utility model provides a shield constructs and measures observation device welds bottom supporting steel plate on the section of jurisdiction bolt after the shaping is assembled to the tunnel, supporting steel plate upper portion welding galvanized steel cylinder, and the centering dish is forced in the welding of steel cylinder top. The measuring device can be used for conveniently and quickly measuring any part of the tunnel, and is low in cost, simple to operate, convenient and safe to erect and high in practicability.
The utility model provides a technical scheme that its technical problem adopted as follows:
the utility model provides a shield constructs and measures observation device, includes galvanized steel cylinder, supporting steel plate, reinforcing bar and forces the centering dish, galvanized steel cylinder bottom install the supporting steel plate, the supporting steel plate contacts with ground, galvanized steel cylinder lateral part welding has the supporting steel bar that is used for supporting the galvanized steel cylinder, the top is installed and is used for the forcing centering dish with measuring instrument pedestal connection.
Furthermore, the welding of support bar have two, two support bars and galvanized steel cylinder form triangle-shaped supporting structure.
Furthermore, the middle part of the forced centering disc is provided with a central screw hole for connecting an instrument.
The utility model has the advantages that:
the utility model discloses a triangle-shaped supporting structure supports, guarantees that observation device can support the observation instrument steadily. Welding bottom sprag steel sheet on the section of jurisdiction bolt after the shaping is assembled to the tunnel, the galvanized steel cylinder of sprag steel sheet upper portion welding, centering dish is forced in the welding of steel cylinder top, can regard as permanent observation post, but convenient and fast carries out measuring work in the arbitrary department of tunnel, and with low costs, easy operation, instrument erection convenience and safety, practicality are strong moreover, are applicable to tunnel real-time measurement, utilize the device can carry out all-weather encryption retest to all control points of tunnel.
Drawings
FIG. 1 is a perspective view of the present invention;
fig. 2 is a front view of the present invention.
In the figure, 1-a galvanized steel cylinder, 2-a supporting steel plate, 3-a supporting steel bar and 4-a forced centering disc.
Detailed Description
The technical solution of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
As shown in fig. 1-2, a shield constructs and measures observation device, including galvanized steel cylinder 1, supporting steel plate 2, supporting steel bar 3 and force centering dish 4, 1 bottom of galvanized steel cylinder install supporting steel plate 2, supporting steel plate 2 and ground contact, 1 lateral part welding of galvanized steel cylinder has the supporting steel bar 3 that is used for supporting galvanized steel cylinder 1, the welding of supporting steel bar 3 has two, two supporting steel bar 3 and 1 formation triangle-shaped supporting structure of galvanized steel cylinder have stability according to triangle-shaped, adopt triangle-shaped supporting structure to support, guarantee that observation device can support the observation instrument steadily. The top of the galvanized steel cylinder 1 is provided with a forced centering disc 4 connected with a measuring instrument base, the middle of the forced centering disc 4 is provided with a central screw hole used for connecting the measuring instrument, during installation, a bottom supporting steel plate 2 is welded on a segment bolt after assembly and forming, a leveling ruler is used for leveling the position of the supporting steel plate 2 on a segment, and then reinforcing steel bars are used for carrying out auxiliary welding on four corners of the steel plate to enable the steel plate to be stressed evenly. Then a galvanized steel cylinder 1 is welded on the top of the steel plate, a forced centering disc 4 is welded on the top of the steel cylinder, and finally supporting reinforcing steel bars 3 are used for supporting and reinforcing the two sides of the steel cylinder, so that permanent observation points are formed, and all control points of the tunnel can be conveniently and quickly subjected to encryption retest. When the instrument is prepared for measurement, the instrument base is connected with the thread of the central screw hole of the forced centering disc 4 through the connecting screw and then screwed tightly, so that the instrument is fixed. Through a foot spiral leveling instrument on the instrument base, the centering disc 4 is forced to be the point location center of the measurement control point, and directional observation can be carried out on the arrangement of the control network. After the observation is finished, take off instrument and connecting screw, will center the dish visor lid and cover, can regard as permanent observation post, but convenient and fast carries out measurement work in the arbitrary department of tunnel, and with low costs, easy operation, instrument set up convenient and safety, practicality are strong moreover, are applicable to tunnel real-time measurement, utilize the device can carry out all-weather encryption retest to all control points of tunnel.
The utility model discloses an installation:
during installation, a bottom supporting steel plate 2 is welded on the segment bolt after assembly and forming, a horizontal ruler is used for leveling the position of the supporting steel plate 2 on the segment, and reinforcing steel bars are used for carrying out auxiliary welding on four corners of the steel plates to enable the steel plates to be stressed evenly. Then a galvanized steel cylinder 1 is welded on the top of the steel plate, a forced centering disc 4 is welded on the top of the steel cylinder, finally, supporting reinforcing steel bars 3 are used for supporting and reinforcing the two sides of the steel cylinder, and then the instrument base is screwed after being connected with the threads of the central screw hole of the forced centering disc 4 through connecting screws, so that the instrument is fixed. The instrument is helically leveled by feet on the instrument base.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
