Description
本発明は、トンネルの坑口又は坑内を閉塞する移動式トンネル防音壁のダンパー装置に関する。 The present invention relates to a damper device for a mobile tunnel soundproof wall that closes a tunnel entrance or inside a tunnel.
工事の進行に伴う現場の移動に際しても、容易に移動することができる移動式トンネル防音壁が提案されている（特許文献１）。
特許文献１に開示されているような移動式トンネル防音壁には、トンネル内に清浄な空気を導入するために風管が取り付けられる。特許文献１では、風管接続金具として開示されている。
A mobile tunnel soundproof wall that can be easily moved even when the site moves with the progress of construction has been proposed (Patent Document 1).
A wind tunnel is attached to a mobile tunnel soundproof wall as disclosed in Patent Document 1 in order to introduce clean air into the tunnel. In patent document 1, it is disclosed as a wind pipe connection fitting.
一般的には、トンネル内に清浄な空気を導入するための風管内には、ダンパーが配置される。このダンパーは、空気導入時には風管内を開とするように位置し、空気の導入停止時にはトンネル内からの粉塵が外部に漏れないように風管内を閉とする。
しかし、風管内にダンパーを配置すると、空気導入時にも通風抵抗となり圧力損失を生じる。
特にトンネル工事は、交替制で２４時間作業が行われることもあり、ダンパーによる圧力損失で生じる電力ロスは決して小さくなく、シミュレーションによれば、年間数百〜数千万円の費用が無駄になることが判明した。
Generally, a damper is disposed in a wind pipe for introducing clean air into a tunnel. The damper is positioned so that the inside of the wind pipe is opened when air is introduced, and the inside of the wind pipe is closed so that dust from the tunnel does not leak outside when the introduction of air is stopped.
However, if a damper is disposed in the wind pipe, it will become a draft resistance even when air is introduced, resulting in a pressure loss.
In particular, tunnel construction may be carried out 24 hours a day on a shift basis, and the power loss caused by the pressure loss due to the damper is never small. According to the simulation, the cost of several hundred to several tens of millions of yen is wasted per year. It has been found.
本発明は、ダンパーによる風管内の圧力損失を無くし、電力ロスの無い移動式トンネル防音壁のダンパー装置を提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a damper device for a mobile tunnel soundproof wall that eliminates pressure loss in the wind pipe caused by the damper and has no power loss.

The damper mechanism 40 includes an inverted damper 41 and a damper receiving member 42 fixed around the wind tube opening 20.
倒立式ダンパー４１は、一端４１ａを移動式トンネル防音壁１０に回動自在に設け、他端４１ｂを自由端とし、風管５０の外部に設けている。本実施例のように、風管開口部２０を閉塞する倒立式ダンパー４１を風管５０外に配置することで、風管５０を使った送風時に風管５０内での抵抗を生じることがない。
図３及び図４に示すように、倒立式ダンパー４１は、風管開口部２０を開放状態とした時には、倒立式ダンパー４１によって風管５０を下方から支える。本実施例によれば、倒立式ダンパー４１によって風管５０を下方から支えるため、送風時に風管５０の躍りを防止でき、風管５０が風管開口部２０によって損傷することを防ぐことができる。
図５及び図６に示すように、倒立式ダンパー４１は、他端（自由端）４１ｂを上方へ引き上げることで風管開口部２０を閉塞状態とする。
The inverted damper 41 is provided outside the wind pipe 50 with one end 41a being rotatably provided on the movable tunnel soundproof wall 10 and the other end 41b being a free end. As in the present embodiment, the inverted damper 41 that closes the wind tube opening 20 is disposed outside the wind tube 50, so that resistance in the wind tube 50 does not occur when the wind tube 50 is blown. .
As shown in FIGS. 3 and 4, the inverted damper 41 supports the wind pipe 50 from below when the wind pipe opening 20 is opened. According to the present embodiment, since the wind pipe 50 is supported from below by the inverted damper 41, the wind pipe 50 can be prevented from jumping during blowing, and the wind pipe 50 can be prevented from being damaged by the wind pipe opening 20. .
As shown in FIGS. 5 and 6, the inverted damper 41 brings the other end (free end) 41 b upward to close the wind tube opening 20.
図４及び図６に示すように、倒立式ダンパー４１は、自由端４１ｂに凹部４１ｃが形成され、風管開口部２０を閉塞状態とした時には、凹部４１ｃに風管５０を収容する。また、自由端４１ｂの凹部４１ｃの両側端は、凹部４１ｃに向けて傾斜させている。なお、凹部４１ｃは、自由端４１ｂの全幅に渡って形成してもよい。また、凹部４１ｃは、図示のように開口側が広い台形状であることが好ましい。また、凹部４１ｃを形成する内周端には、ローラのような摺動部材４１ｄを設けることが好ましい。
本実施例によれば、風管５０を凹部４１ｃに収容できるので、移動式トンネル防音壁１０の移動時やトンネル発破時に、風管５０を切断したり、取り外す必要が無いため、工事費の大幅な低減を図れる。なお、倒立式ダンパー４１の上方への引き上げに伴い、風管５０は凹部４１ｃの両側端の傾斜によって凹部４１ｃに導かれ、凹部４１ｃ内に収容される。凹部４１ｃを開口側が広い台形状とし、又は摺動部材４１ｄを設けることで、風管５０はスムーズに凹部４１ｃに導かれる。
図３及び図４に示すように、倒立式ダンパー４１の自由端４１ｂには、ワイヤー４３の一端が接続されている。
ワイヤー４３の他端は、図３及び図５に示すウインチ４４に接続されている。
ウインチ４４によってワイヤー４３を巻き取ることで、倒立式ダンパー４１は閉塞状態となり、ウインチ４４によってワイヤー４３を緩めることで、倒立式ダンパー４１は開放状態となる。
As shown in FIGS. 4 and 6, the inverted damper 41 has a recess 41 c formed in the free end 41 b and accommodates the wind tube 50 in the recess 41 c when the wind tube opening 20 is closed. Further, both side ends of the recess 41c of the free end 41b are inclined toward the recess 41c. In addition, you may form the recessed part 41c over the full width of the free end 41b. Moreover, it is preferable that the recessed part 41c is trapezoid shape with a wide opening side like illustration. Moreover, it is preferable to provide the sliding member 41d like a roller in the inner peripheral end which forms the recessed part 41c.
According to the present embodiment, since the wind pipe 50 can be accommodated in the recess 41c, there is no need to cut or remove the wind pipe 50 when the mobile tunnel soundproof wall 10 is moved or when the tunnel is blasted. Reduction can be achieved. As the inverted damper 41 is pulled upward, the wind pipe 50 is guided to the recess 41c by the inclination of both side ends of the recess 41c and is accommodated in the recess 41c. By making the concave portion 41c trapezoidal on the opening side or by providing the sliding member 41d, the wind pipe 50 is smoothly guided to the concave portion 41c.
As shown in FIGS. 3 and 4, one end of a wire 43 is connected to the free end 41 b of the inverted damper 41.
The other end of the wire 43 is connected to a winch 44 shown in FIGS.
By winding the wire 43 with the winch 44, the inverted damper 41 is closed, and by loosening the wire 43 with the winch 44, the inverted damper 41 is opened.
ダンパー受け部材４２は、少なくとも天板４２ａと一対の側板４２ｂとによって開口部４２ｃを形成し、開口部４２ｃに倒立式ダンパー４１を当接させて風管開口部２０を閉塞状態とする。本実施例によれば、閉塞時にダンパー受け部材４２と倒立式ダンパー４１との間に空間が形成されるため、この空間に風管５０を収めることができ、またこの空間に風管５０を収めることでトンネル発破時に発生する圧力が風管開口部２０から外に伝わることを防止できる。 The damper receiving member 42 forms an opening 42c by at least the top plate 42a and the pair of side plates 42b, and the inverted damper 41 is brought into contact with the opening 42c so that the wind tube opening 20 is closed. According to the present embodiment, since a space is formed between the damper receiving member 42 and the inverted damper 41 when closed, the wind tube 50 can be accommodated in this space, and the wind tube 50 is accommodated in this space. Thus, it is possible to prevent the pressure generated at the time of tunnel blasting from being transmitted from the wind tube opening 20 to the outside.
ダンパー機構４０は、開放状態にある倒立式ダンパー４１を支える保持部材４５を有している。保持部材４５は、それぞれの側板４２ｂに一端を接合した一対の第１保持部材４５ａと、移動式トンネル防音壁１０に一端を接合して移動式トンネル防音壁１０から延出させた一対の第２保持部材４５ｂと、一対の第１保持部材４５ａのそれぞれの他端、及び一対の第２保持部材４５ｂのそれぞれの他端に接合される第３保持部材４５ｃとで構成している。
開放状態にある倒立式ダンパー４１は、第２保持部材４５ｂと第３保持部材４５ｃとによって保持される。
風管５０は、倒立式ダンパー４１の上面で保持されるとともに、一対の側板４２ｂ及び一対の第１保持部材４５ａによって水平方向の動きを規制される。
The damper mechanism 40 includes a holding member 45 that supports the inverted damper 41 in an open state. The holding member 45 has a pair of first holding members 45a whose one ends are joined to the respective side plates 42b, and a pair of second holding members whose one ends are joined to the mobile tunnel soundproof wall 10 and extended from the mobile tunnel soundproof wall 10. The holding member 45b includes a third holding member 45c joined to the other end of each of the pair of first holding members 45a and the other end of the pair of second holding members 45b.
The inverted damper 41 in the open state is held by the second holding member 45b and the third holding member 45c.
The wind pipe 50 is held on the upper surface of the inverted damper 41, and the horizontal movement is restricted by the pair of side plates 42b and the pair of first holding members 45a.
