Description

本発明は、橋梁架設用の仮受ベント設備の監視方法と、その方法を実施する監視システムに関する。 The present invention relates to a method for monitoring a temporary receiving vent facility for bridge construction, and a monitoring system for implementing the method.

橋梁等の傾斜の変化を計測して無線送信し、監視する、橋梁等の傾斜変化測定技術が知られている（例えば特許文献１参照）。 There is known a technique for measuring a change in inclination of a bridge or the like, which measures a change in inclination of the bridge or the like, wirelessly transmits the change, and monitors the change (for example, see Patent Document 1).

鋼橋梁現場架設工事は、仮受ベント設備（大型特殊支保工）を用いて、トラッククレーンで架設する工法が一般的であるが、橋梁架設途中に仮受ベントが公道上などに転倒する事故が発生すると、地域住民に多大な迷惑をかけ社会的責任は重大である。
その転倒防止対策として、仮受ベントの鉛直度を、測量機器を用いて測定している状況である。
仮受ベントの傾斜要因としては、１）仮受ベントの荷重載荷に伴う基礎の不等沈下による倒れ、２）鋼桁架設時における仮受ベントへの偏心載荷による倒れ、３）季節ごとの昼・夜温度変化による鋼桁の伸縮の影響による倒れ、４）地震荷重・風荷重等の水平力による倒れ等が考えられる。 For steel bridge construction, it is common to use a temporary crane vent equipment (large special support work) to erect with a truck crane.However, during the bridge construction, temporary accident vents may fall on public roads. If it occurs, it will cause a great deal of inconvenience to local residents, and social responsibility will be significant.
As a measure to prevent the fall, the verticality of the temporary reception vent is being measured using surveying equipment.
The factors of inclination of the temporary reception vent are 1) collapse due to uneven settlement of the foundation due to load loading of the temporary reception vent, 2) collapse due to eccentric loading on the temporary reception vent during steel girder installation, and 3) daytime depending on the season.・Collapse due to the expansion and contraction of steel girder due to night temperature change, 4) Crash due to horizontal force such as earthquake load and wind load.

なお、特許文献２において、支保工の傾斜角を計測する測定器を用いて、傾斜角の変化を計測して不等沈下量を算出し、その算出値が許容値を越えたときに警告器を作動させる、支保工の不等沈下監視技術が提案されている。 In Patent Document 2, a measuring device for measuring the inclination angle of the support work is used to measure the change in the inclination angle to calculate the unequal settlement amount, and when the calculated value exceeds the allowable value, a warning device is issued. An unequal subsidence monitoring technique for supporting work has been proposed.

特開２０１３−４４７３９号公報JP, 2013-44739, A 特開平１１−１５３４３１号公報JP, 11-153431, A

しかし、特許文献１の橋梁等の傾斜変化測定技術では、先ず、橋梁、重要構造物の急斜地の傾斜計測と記載されているが、実際に活用するための計測要領図はない。また、電源は一般的な電源を使用するものと思われ、その場合、電線の切断・停電等の対処が問題となる。そして、警報について、休日・深夜間の緊急警報はどのように伝達されているか不明である。 However, in the technology for measuring the change in inclination of bridges and the like in Patent Document 1, first, although it is described that the inclination of steep slopes of bridges and important structures is measured, there is no measurement procedure diagram for practical use. In addition, it seems that a general power source is used as the power source, and in such a case, there is a problem in dealing with the disconnection of the electric wire, the power failure and the like. As for warnings, it is unknown how emergency warnings for holidays and late nights are transmitted.

また、特許文献２の支保工の不等沈下監視技術では、先ず、支保工の狭隘な現場内で、ワイヤー式エンコーダーの配置は困難であり、実際の活用頻度は限りなく少ないと思われる。そして、ビデオカメラでの監視については、支保工の狭隘な現場では障害物が多く、実際の使用範囲は限定される。また、電源は一般電源を使用しているが、専用の電源ボックスが必要となる。さらに、異常時の警報は、現場内だけの警報であり、作業関係者が離れた場合は確認できない。例えば、突発的な地震対応はできない。 Further, in the uneven settlement monitoring technique of the support work of Patent Document 2, first, it is difficult to arrange the wire type encoder in the narrow site of the support work, and it is considered that the frequency of practical use is limitless. As for monitoring with a video camera, there are many obstacles in the narrow area of support work, and the actual range of use is limited. In addition, although the power source uses a general power source, a dedicated power source box is required. Furthermore, the alarm at the time of abnormality is an alarm only at the site, and cannot be confirmed when the person involved in the work leaves. For example, a sudden earthquake cannot be dealt with.

特に、橋梁架設用の仮受ベント設備において、突発的な地震・強風時の対応は困難であり、問題として残っている。 In particular, with the temporary venting equipment for bridge construction, it is difficult to deal with sudden earthquakes and strong winds, and this remains a problem.

本発明の課題は、橋梁架設用の仮受ベント設備において、その傾斜等を常時監視して、制限値を超えた場合は、登録管理者の携帯端末に緊急報知を可能とすることである。 An object of the present invention is to constantly monitor the inclination and the like of a temporary receiving vent facility for bridge construction, and when the limit value is exceeded, it is possible to make an emergency notification to a mobile terminal of a registration manager.

以上、実施形態の構成による橋梁架設用仮受ベント設備の監視方法及びシステムによれば、仮受ベント設備４に取り付けた傾斜センサ１１及び歪センサ２１からの測定情報に基づいて仮受ベント設備４の鉛直状態及び傾斜状態と鉛直状態からの歪状態を常時監視することによって、仮受ベント設備４の傾斜及び歪が制限値を超えた場合には、登録管理者の携帯端末８に緊急報知することができる。 As described above, according to the method and system for monitoring the temporary receiving vent equipment for bridge construction according to the configuration of the embodiment, the temporary receiving vent equipment 4 is based on the measurement information from the tilt sensor 11 and the strain sensor 21 attached to the temporary receiving vent equipment 4. By constantly monitoring the vertical state and the inclined state and the strain state from the vertical state, when the inclination and the strain of the temporary receiving vent equipment 4 exceed the limit values, an emergency notification is given to the portable terminal 8 of the registered manager. be able to.

すなわち、先ず、仮受ベント設備４に取り付けた傾斜センサ１１からの傾斜測定情報に基づいて仮受ベント設備４の前後方向と左右方向の鉛直状態及び傾斜状態を常時監視して、仮受ベント設備４の傾斜が制限値を超えた場合には、登録管理者の携帯端末８に緊急報知することができる。
したがって、その緊急報知を受けた登録管理者等は、仮受ベント設備４の傾斜状態に対する適切な修復作業を行うことができる。 That is, first, based on the tilt measurement information from the tilt sensor 11 attached to the temporary receiving vent equipment 4, the vertical state and the tilting state of the temporary receiving vent equipment 4 in the front-rear direction and the left-right direction are constantly monitored to check the temporary receiving vent equipment. When the inclination of No. 4 exceeds the limit value, it is possible to make an emergency notification to the mobile terminal 8 of the registration manager.
Therefore, the registration manager or the like who has received the emergency notification can perform an appropriate repair work for the inclined state of the temporary receiving vent equipment 4.

さらに、仮受ベント設備４に取り付けた歪センサ２１からの歪測定情報に基づいて仮受ベント設備４の前後方向と左右方向の鉛直状態からの歪状態を常時監視して、仮受ベント設備４の歪が制限値を超えた場合には、登録管理者の携帯端末８に緊急報知することができる。
したがって、その緊急報知を受けた登録管理者等は、仮受ベント設備４の歪状態に対する適切な修復作業を行うことができる。 Furthermore, based on the strain measurement information from the strain sensor 21 attached to the temporary receiving vent equipment 4, the temporary receiving vent equipment 4 is constantly monitored for the strain state from the vertical state in the front-rear direction and the left-right direction, and the temporary receiving vent equipment 4 When the distortion of exceeds the limit value, it is possible to make an emergency notification to the mobile terminal 8 of the registration manager.

そして、仮受ベント設備４に歪センサ２１を配置することで、傾斜による内部応力の測定、並びに橋梁架設工事途中における荷重増加に対する内部応力を監視することができ、安全性は向上する。つまり、傾斜の影響だけでなく、例えば設計・計画ミス等による荷重オーバーの検証もできる。
また、橋梁架設工事において重要仮設設備である、仮受けベント設備４の傾斜計測と 応力測定を同時に行うことで、工事の安全管理システムが一元化される。さらに、早期に対策を講ずることができる。したがって、市街地内の橋梁・鉄道近接工事などの重要なインフラ工事で活用することができる。 By disposing the strain sensor 21 in the temporary receiving vent equipment 4, it is possible to measure the internal stress due to the inclination and to monitor the internal stress with respect to the load increase during the bridge construction work, and the safety is improved. That is, not only the influence of the inclination but also the overload verification due to, for example, a design/plan mistake can be verified.
Also, by simultaneously measuring the inclination and stress of the temporary receiving and venting equipment 4, which is an important temporary equipment in the bridge construction work, the safety management system for the construction is unified. Furthermore, measures can be taken early. Therefore, it can be utilized for important infrastructure work such as bridge/railway construction work in urban areas.

特に、最低１年充電不要な小型バッテリーを内蔵した傾斜センサ１１及び歪センサ２１と無線通信により計測システムが簡素化されており、仮受けベント設備４の狭隘な現場の中に大型の測定装置・電線・計測線は不要である。 In particular, the measurement system is simplified by wireless communication with the tilt sensor 11 and strain sensor 21 that have a built-in small battery that does not require charging for at least one year, and a large measuring device can be installed in the narrow space of the temporary receiving vent equipment 4. No wires or measurement lines are needed.

ここで、仮受ベント設備４の四隅の柱４２の側面と前面又は後面に傾斜センサ１１と歪センサ２１を各々取り付けることで、四隅の柱４２の前後方向と左右方向において、鉛直状態及び傾斜状態と鉛直状態からの歪状態を常時監視することができる。
なお、傾斜センサ１１は、図１に示したように、柱４２の頂部付近に配置した方が傾斜の測定に好都合と考えられるが、他の適切な高さ配置してもよい。
また、歪センサ２１については、鉛直状態からの歪を検知し得る適切な高さに配置すればよい。 Here, the tilt sensor 11 and the strain sensor 21 are attached to the side surface and the front surface or the rear surface of the four corner columns 42 of the temporary receiving vent equipment 4, respectively, so that the vertical state and the tilt state in the front-rear direction and the left-right direction of the four corner columns 42. And the strain state from the vertical state can be constantly monitored.
It should be noted that it is considered more convenient to measure the tilt when the tilt sensor 11 is arranged near the top of the column 42 as shown in FIG. 1, but it may be arranged at another suitable height.
Further, the strain sensor 21 may be arranged at an appropriate height capable of detecting the strain from the vertical state.

（変形例）
以上の実施形態では、仮受ベント設備４において、柱４２に傾斜センサ１１と歪センサ２１を取り付けたが、頂部梁４４に傾斜センサ１１を取り付けたり、水平材４３に歪センサ２１を取り付けたりしてもよく、仮受ベント設備４に対する傾斜センサ１１と歪センサ２１の取付位置は任意である。
また、仮受ベント設備の構成、監視システムの具体的な構成、例えば傾斜センサ、歪センサ及び送信モジュール等についても適宜に変更可能であることは勿論である。 (Modification)
In the above embodiment, the inclination sensor 11 and the strain sensor 21 are attached to the column 42 in the temporary reception vent equipment 4, but the inclination sensor 11 is attached to the top beam 44 or the strain sensor 21 is attached to the horizontal member 43. However, the mounting positions of the tilt sensor 11 and the strain sensor 21 with respect to the temporary receiving vent equipment 4 are arbitrary.
Further, it is needless to say that the configuration of the temporary receiving vent equipment and the specific configuration of the monitoring system, such as the inclination sensor, the strain sensor, and the transmission module, can be appropriately changed.

さらに、ドーム球場等の大空間構造建方工事で、高い仮受ベントを数多く配置して進める工事もあり、そのような特殊構造物構築工事に当システムを活用することで安全性は向上する。
また、本発明の技術は、仮受ベント設備だけではなく、施工中の構造物（主柱他）の傾斜、歪測定にも活用できる。 In addition, there are also construction works for large space structures such as dome stadiums, where many high-temporary receiving vents are placed, and safety is improved by utilizing this system for such special structure construction work.
Further, the technique of the present invention can be utilized not only for temporary receiving vent equipment but also for measuring the inclination and strain of a structure (main pillar etc.) under construction.
