Description

本発明は、油圧ハンマ等の杭打機による鋼管杭などの既製杭の杭打ちに用いられる杭打機用防音装置に関し、杭の打設時に発生する打撃音を効果的に低減できるようにしたものである。   The present invention relates to a soundproofing device for a pile driving machine that is used for pile driving of a prefabricated pile such as a steel pipe pile by a pile driving machine such as a hydraulic hammer, and is capable of effectively reducing the impact sound generated when the pile is driven. Is.

一般に、油圧ハンマ等の杭打機によって鋼管杭などの既製杭を打撃して地中に打設する杭は、大きな騒音や振動を伴うため法規制により現在市街地ではほとんど実施されていない。   In general, piles that are made by hitting off-the-shelf piles such as steel pipe piles with a pile driver such as a hydraulic hammer are placed in the ground due to large noises and vibrations, and are rarely implemented in urban areas due to legal regulations.

しかし、杭打機による杭打ちは施工速度が速く、効率的かつ経済的に杭打ちを行うことができ、また、支持層への貫入、支持力の推定が容易などのメリットがあるため、近年見直されている。   However, pile driving with a pile driver is fast in construction speed, can be piled up efficiently and economically, and has advantages such as easy penetration into the support layer and estimation of support force. It has been reviewed.

ところで、杭打機による杭打ちには、通常、杭打ちに伴う打撃音を低減するための防音カバーが用いられる。例えば、特許文献１には、杭(12)の頭部と当該杭頭部に落とされた杭打機(14)が衝突する部分の外周を筒状に覆う筒状カバー(16)と、当該筒状カバー(16)の内側に設置され、筒状カバー(16)と杭(12)間の隙間を塞いで筒状カバー(16)の下部開口からの打撃音の音漏れを防止する吸音材からなる傘状の下面カバー(20)とを備えた杭打機用防音装置の発明が開示されている。   By the way, the soundproof cover for reducing the striking sound accompanying the pile driving is usually used for the pile driving by the pile driving machine. For example, Patent Document 1 discloses a cylindrical cover (16) that covers the outer periphery of a portion where a head of a pile (12) and a pile driver (14) dropped on the pile head collide with each other, A sound-absorbing material that is installed inside the cylindrical cover (16) and closes the gap between the cylindrical cover (16) and the pile (12) to prevent sound leakage from the lower opening of the cylindrical cover (16) An invention of a soundproofing device for a pile driver provided with an umbrella-shaped lower surface cover (20) made of

また、特許文献２には、長尺の筒状に形成した防音シート(1)の胴部に大リング(2)と小リング(3)を交互に固定して伸縮可能な蛇腹状となし、この防音シート(1)の最上部を杭打機の下部に接続固定し得るようにした杭打機の防音カバーの発明が開示されている。   Patent Document 2 discloses a bellows shape that can be expanded and contracted by alternately fixing a large ring (2) and a small ring (3) to the body of a soundproof sheet (1) formed in a long cylindrical shape, An invention of a soundproof cover for a pile driving machine is disclosed in which the uppermost part of the soundproof sheet (1) can be connected and fixed to the lower part of the pile driving machine.

しかし、特許文献１の杭打機用防音装置および特許文献２の防音カバーは、いずれも杭の頭部または全体を単に防音材で覆って打撃音が周囲に漏れないようにするものであり、防音効果はもっぱら防音材の吸音と遮音によるものであるため自ずと限界があった。   However, the soundproofing device for the pile driving machine of Patent Document 1 and the soundproofing cover of Patent Document 2 are all designed to prevent the impact sound from leaking to the surroundings by simply covering the head or the whole of the pile with a soundproofing material, Since the soundproofing effect is solely due to the sound absorption and sound insulation of the soundproofing material, there was a limit naturally.

本発明は、以上の課題を開発するためになされたもので、油圧ハンマ等の杭打機による杭の打設時に発生する打撃音を効率的に低減できるようにした杭打機用防音装置を提供することを目的とするものである。   The present invention has been made in order to develop the above-described problem, and provides a soundproofing device for a pile driving machine that can efficiently reduce the impact sound generated when a pile is driven by a pile driving machine such as a hydraulic hammer. It is intended to provide.

本発明は、杭打機による杭の打設時に発生する杭の打撃音をきわめて効果的に低減できるようにした杭打機用防音装置の発明であり、前記杭の頭部と前記杭打機との当接面(杭頭部と杭打機との接触面)の外周を含む前記杭の外周を前記杭の材軸方向の一定範囲に亘って覆う筒状の上部防音室と、当該上部防音室の下側に位置し、前記杭の前記上部防音室より下方部分の外周を覆う下部防音室とを備え、前記下部防音室は前記上部防音室と連続する空間をなし、かつ前記杭の側方に急拡大して断面が前記上部防音室より広くなっていることを特徴とするものである。   The present invention is an invention of a soundproofing device for a pile driving machine capable of extremely effectively reducing a hammering sound generated when a pile is driven by a pile driving machine, the head of the pile and the pile driving machine A cylindrical upper soundproof chamber that covers the outer periphery of the pile including the outer periphery of the contact surface (contact surface between the pile head and the pile driver) over a certain range in the material axis direction of the pile, and the upper part A lower soundproofing chamber located on the lower side of the soundproofing chamber and covering an outer periphery of a portion below the upper soundproofing room of the pile, the lower soundproofing room forming a space continuous with the upper soundproofing room, and It is characterized in that it expands rapidly to the side and the cross section becomes wider than the upper soundproof room.

前記下部防音室を前記上部防音室と連続する空間とし、かつ前記杭の側方に急激に拡大させて前記上部防音室より広くすることで、杭の頭部と杭打機との当接面(杭頭部と杭打機との接触面)で発生した打撃音は、上部防音室内を伝わって下部防音室内で急激に拡散されることにより音エネルギーが減衰されるため、杭の打撃音は低減される。   The lower soundproofing chamber is a space that is continuous with the upper soundproofing chamber, and is abruptly expanded to the side of the pile so as to be wider than the upper soundproofing chamber, so that the contact surface between the pile head and the pile driver The striking sound generated at (the contact surface between the pile head and the pile driver) travels through the upper soundproof chamber and is diffused rapidly in the lower soundproof chamber. Reduced.

また、下部防音室で低減された音エネルギーは、下部防音室の内周に設置された発泡ウレタン等からなる吸音材に吸収され、さらに吸音材を透過した音エネルギーは吸音材の外側に設置された鋼板などからなる遮音材によって遮音されるため、杭の打撃音はさらに低減される。   In addition, the sound energy reduced in the lower soundproof room is absorbed by the sound absorbing material made of urethane foam or the like installed on the inner periphery of the lower soundproof room, and the sound energy that has passed through the sound absorbing material is installed outside the sound absorbing material. Since the sound is insulated by a sound insulating material such as a steel plate, the impact sound of the pile is further reduced.

なお、上部防音室および下部防音室の形状は特に限定されるものではないが、上部防音室は円筒形状、下部防音室は直方体形状とするのが構造的に優れている。   The shapes of the upper soundproof room and the lower soundproof room are not particularly limited, but it is structurally superior that the upper soundproof room has a cylindrical shape and the lower soundproof room has a rectangular parallelepiped shape.

さらに、前記下部防音室を前記上部防音室より前記杭の径方向に大きく構成することにより、装置全体の重心が低くなり安定性が高められる。なお、下部防音室の内法高(天井高)は、下部防音室で杭の打止め管理などの杭打ちに伴う作業があることから、下部防音室でこれらの作業を円滑に行える高さが確保されていることが望ましい。   Furthermore, by constructing the lower soundproof room larger than the upper soundproof room in the radial direction of the pile, the center of gravity of the entire apparatus is lowered and the stability is improved. The internal height (ceiling height) of the lower soundproof room is high enough to perform these work smoothly in the lower soundproof room because there are work related to pile driving such as pile stop management in the lower soundproof room. It is desirable that it is secured.

また、前記上部防音室と前記下部防音室を分割可能に構成し、さらに前記下部防音室を複数に分割可能に構成することにより運搬や保管等に際して取り扱いが容易になる。   In addition, the upper soundproof room and the lower soundproof room are configured to be separable, and the lower soundproof room is configured to be separable into a plurality of parts, thereby facilitating handling during transportation and storage.

なお、上部防音室も必要に応じて軸方向に複数に分割可能に構成することにより杭の長さに合わせて高さを変更することができる。   Note that the height of the upper soundproof room can be changed according to the length of the pile by configuring the upper soundproof room so as to be divided into a plurality of parts in the axial direction as necessary.

本発明は、特に下部防音室がその上側に位置する上部防音室と連続する空間に構成され、かつ杭の側方に急拡大して前記上部防音室より広く構成されていることで、杭の頭部と杭打機との当接面(杭頭部と杭打機との接触面)で発生した打撃音は、上部防音室内を伝わって下部防音室内で急激に拡散することにより音エネルギーが減衰されることにより杭の打撃音を低減することができる。   The present invention is particularly configured such that the lower soundproofing room is configured in a space continuous with the upper soundproofing room located on the upper side thereof, and is expanded to the side of the pile so as to be wider than the upper soundproofing room. The striking sound generated on the contact surface between the head and the pile driver (the contact surface between the pile head and the pile driver) travels through the upper soundproof room and rapidly diffuses in the lower soundproof room, resulting in sound energy. Damping sound of the pile can be reduced by being attenuated.

さらに、下部防音室で減衰された音エネルギーは、下部防音室の内周に設置された発泡ウレタン等からなる吸音材に吸収され、さらに吸音材を透過した音エネルギーは吸音材の外側に設置された鋼板などからなる遮音材によって遮音されるため、杭の打撃音をさらに低減することができる。   Furthermore, the sound energy attenuated in the lower soundproof room is absorbed by a sound absorbing material made of foamed urethane or the like installed on the inner periphery of the lower soundproof room, and the sound energy transmitted through the sound absorbing material is installed outside the sound absorbing material. Since the sound is insulated by a sound insulating material such as a steel plate, the impact sound of the pile can be further reduced.

また、下部防音室を上部防音室より杭の側方向に大きく構成されているため、装置全体の重心が低く安定性に優れている。また、上部防音室と下部防音室が分割可能に構成され、さらに下部防音室が複数に分割可能に構成されているため、運搬や保管等に際して取扱いがきわめて容易である。   Moreover, since the lower soundproof room is larger than the upper soundproof room in the side of the pile, the center of gravity of the entire apparatus is low and the stability is excellent. Further, since the upper soundproof room and the lower soundproof room are configured to be separable and the lower soundproof room is configured to be separable into a plurality of parts, handling is extremely easy during transportation and storage.

図１〜図５は、本発明の一実施形態を図示したものであり、図において、杭打機用防音装置１は、上部防音室２および当該上部防音室２の下側に位置する下部防音室３の地表面から出ている杭Ａの全長を覆うことが可能な大きさに構成されている(図２参照)。   1 to 5 illustrate an embodiment of the present invention. In the figure, a soundproofing device 1 for a pile driver is represented by an upper soundproofing chamber 2 and a lower soundproofing located below the upper soundproofing chamber 2. It is comprised in the magnitude | size which can cover the full length of the pile A which has come out from the ground surface of the chamber 3 (refer FIG. 2).

上部防音室２は、杭打機Ｂによる打撃時の杭Ａの頭部と杭打機Ｂとの当接面(杭頭部と杭打機との接触面)の外周を含む杭Ａの外周を杭Ａの軸方向の一定範囲に亘って覆う円筒形状に構成されている。   The upper soundproof room 2 has an outer periphery of the pile A including the outer periphery of the contact surface (the contact surface between the pile head and the pile driver) between the head of the pile A and the pile driver B when hit by the pile driver B. Is formed in a cylindrical shape that covers a certain range in the axial direction of the pile A.

また、コルゲートパイプやライナープレート等からなる遮音材2aと当該遮音材2aの内側に設置された発泡ウレタン等からなる吸音材2bとから二重に構成されている(図５参照)。   Further, the sound insulating material 2a made of a corrugated pipe, a liner plate or the like and the sound absorbing material 2b made of foamed urethane or the like installed inside the sound insulating material 2a are doubled (see FIG. 5).

また、上部防音室２は、下部防音室３の上端部のほぼ中央に立設され、かつ下部防音室３の上端部にアングル材と連結ボルト等からなる複数の接続用金具４によって脱着可能に固定されている。   Further, the upper soundproof chamber 2 is erected substantially at the center of the upper end portion of the lower soundproof chamber 3 and can be attached to and detached from the upper end portion of the lower soundproof chamber 3 by a plurality of connection fittings 4 made of angle members, connecting bolts, and the like. It is fixed.

また、上部防音室２の上端部と下部防音室３の各コーナ部との間に転倒防止ワイヤー14が架設され、各転倒防止ワイヤー14の下端部14aは後述する吊受け及び転倒防止受け13の結束孔13aに結束されている。なお、接続用金具４は上部防音室２の周方向に一定間隔おきに取り付けられている。   Further, a fall prevention wire 14 is installed between the upper end portion of the upper soundproof chamber 2 and each corner portion of the lower soundproof chamber 3, and the lower end portion 14 a of each fall prevention wire 14 is a suspension receiver and a fall prevention receiver 13 described later. It is bound in the binding hole 13a. The connecting metal fittings 4 are attached at regular intervals in the circumferential direction of the upper soundproof chamber 2.

下部防音室３は、上部防音室２の下端面より下方の、杭Ａの外周を覆う直方体の箱状に構成され、また、上部防音室２より杭Ａの側方向(直径方向)に大きく構成され、これにより重心が低くなり安定性が図られている。   The lower soundproof room 3 is configured in a rectangular parallelepiped box shape covering the outer periphery of the pile A below the lower end surface of the upper soundproof room 2, and is configured to be larger in the side direction (diameter direction) of the pile A than the upper soundproof room 2. As a result, the center of gravity is lowered and stability is achieved.

さらに、下部防音室３内は上部防音室２内より杭Ａの側方向に広く、かつ内法高(天井高)は、下部防音室３内で杭の打止め管理などの杭打ちに伴う作業があることから、下部防音室内でこれらの作業に可能な高さが確保されている。   Furthermore, the interior of the lower soundproof room 3 is wider in the lateral direction of the pile A than the upper soundproof room 2, and the inner height (ceiling height) is the work associated with pile driving, such as pile management in the lower soundproof room 3. Therefore, the height possible for these operations is secured in the lower soundproof room.

また、下部防音室３は、Ｈ形鋼などからなる複数の軸組材５より直方体の箱状に構成され、その側面と上面に発泡ウレタン等からなる吸音材６、その外側に鋼板からなる側面遮音材7aと上面遮音材7bがそれぞれ取り付けられ、さらに下面には鋼板からなる床板８が取り付けられている。なお、側面遮音材7aには厚さ４ｍｍ程度の鉄板が用いられ、上面遮音材7bと床板８には厚さ25ｍｍ程度の鉄板が用いられている。   Further, the lower soundproof chamber 3 is formed in a rectangular parallelepiped box shape from a plurality of shaft assemblies 5 made of H-shaped steel or the like, the sound absorbing material 6 made of foamed urethane or the like on its side surface and upper surface, and the side surface made of steel plate on the outside A sound insulating material 7a and an upper surface sound insulating material 7b are respectively attached, and a floor plate 8 made of a steel plate is attached to the lower surface. Note that an iron plate having a thickness of about 4 mm is used for the side surface sound insulating material 7 a, and an iron plate having a thickness of about 25 mm is used for the upper surface sound insulating material 7 b and the floor plate 8.

また、下部防音室３の上端面および下端面の中央に、杭Ａが貫通可能な貫通孔９と10がそれぞれ形成され、貫通孔９を介して下部防音室３内と上部防音室２内は、連続するひとつの空間に連通している。また、貫通孔９の周縁部に鋼板からなる補強プレート11が貫通孔９の周方向にリング状に連続して取り付けられている。   In addition, through holes 9 and 10 through which the pile A can pass are respectively formed in the center of the upper end surface and the lower end surface of the lower soundproof chamber 3, and the inside of the lower soundproof chamber 3 and the upper soundproof chamber 2 are formed through the through holes 9. , It communicates with one continuous space. In addition, a reinforcing plate 11 made of a steel plate is continuously attached in a ring shape in the circumferential direction of the through-hole 9 at the peripheral portion of the through-hole 9.

なお、符号12は下部防音室３の側面に設けられた出入口であり、出入口12には防音構造の扉が取り付けられている。また、符号13は転倒防止ワイヤー14の下端部14aを結束し、また、本装置１をクレーン等で吊る際に、吊りワイヤー15の端部15aを結束するための吊り受け及び転倒防止受けであり、各ワイヤー14,15の端部14a,15aをそれぞれ結束するための結束孔13a,13bを有し、かつ下部防音室３の各コーナ部の上端部に取り付けられている。   Reference numeral 12 denotes an entrance / exit provided on a side surface of the lower soundproof chamber 3, and a door having a soundproof structure is attached to the entrance / exit 12. Reference numeral 13 denotes a suspension receiver and a tipping prevention receiver for binding the lower end portion 14a of the fall prevention wire 14 and for binding the end portion 15a of the suspension wire 15 when the apparatus 1 is suspended by a crane or the like. In addition, bundling holes 13a and 13b for bundling the end portions 14a and 15a of the wires 14 and 15 are provided and attached to the upper end portions of the corner portions of the lower soundproof chamber 3.

このように構成された杭打機用防音装置１は、地上に立設された杭Ａの上にクレーン等で吊って真上から被せられる。そして、杭Ａの上端部を杭打機Ｂによって繰り返し打撃することにより杭Ａを地盤中に打ち込むことができる。   The soundproofing device 1 for a pile driving machine configured in this way is hung with a crane or the like on a pile A erected on the ground and covered from directly above. The pile A can be driven into the ground by repeatedly hitting the upper end of the pile A with the pile driving machine B.

また、杭打機Ｂによる打撃音は、杭Ａの頭部と杭打機Ｂとの当接面で最も大きく発生し、上部防音室２と杭Ａとの間を下方に伝わり、下部防音室３内で急激に拡散することにより音エネルギーが減衰され、打撃音が低減される。   Moreover, the impact sound by the pile driving machine B is generated most at the contact surface between the head of the pile A and the pile driving machine B, is transmitted downward between the upper soundproof room 2 and the pile A, and the lower soundproof room. The sound energy is attenuated by abrupt diffusion within 3, and the hitting sound is reduced.

また、下部防音室３で低減された音エネルギーは、下部防音室３の内周に設置された発泡ウレタン等からなる吸音材６に吸収され、さらに吸音材６を透過した音エネルギーは吸音材６の外側に設置された鋼板などからなる遮音材７によって遮音されるため、杭の打撃音はさらに低減される。   The sound energy reduced in the lower soundproof room 3 is absorbed by the sound absorbing material 6 made of urethane foam or the like installed on the inner periphery of the lower soundproof room 3, and the sound energy transmitted through the sound absorbing material 6 is further absorbed. Since the sound insulation is made by the sound insulation material 7 made of a steel plate or the like installed outside the pile, the sound of hitting the pile is further reduced.

本発明は、油圧ハンマ等の杭打機による鋼管杭などの既製杭の打設時に発生する打撃音を効果的に低減することができる。   INDUSTRIAL APPLICABILITY The present invention can effectively reduce a striking sound generated when a ready-made pile such as a steel pipe pile is driven by a pile hammer such as a hydraulic hammer.
