線域12は後にコンクリートを打設すために所定深さま
でくまなく掘削排土することが必要で、そのために第2
図に示すような掘削機14を用いて溝孔16の掘削が行
なわれる。First, referring to Fig. 1, the shaded areas 12 between the guide members 10 buried at intervals in the ground during the construction process of the diaphragm wall are completely covered to a predetermined depth for later concrete pouring. It is necessary to excavate and remove soil, and for that purpose a second
A trench hole 16 is excavated using an excavator 14 as shown in the figure.
この掘削は通常泥水を満たして孔壁の崩壊を防止しなが
ら行なわれる。This excavation is usually carried out while filling the hole with mud to prevent collapse of the hole wall.
図示のタイプの掘削機14は開閉可能のシェル18を備
えたパケット方式のものであるが、本考案の趣旨に照ら
して掘削機の方式はパケット方式であると否とを問わな
い。Although the illustrated type of excavator 14 is of a packet type with a shell 18 that can be opened and closed, it does not matter whether the type of excavator is a packet type or not in light of the spirit of the present invention.
掘削機14は、その相対する両側部、図示の例ではケー
シング20の相対する両側部のそれぞれに設けられた上
方の案内手段22および下方の案内手段24を備える。The excavator 14 comprises an upper guide means 22 and a lower guide means 24 provided on opposite sides thereof, in the example shown, on opposite sides of the casing 20 .
掘削時、掘削機14はその側部すなわちケーシング20
の側部が案内部材10に向い合うように該案内部材間に
位置決められる。When excavating, the excavator 14 uses its side or casing 20
is positioned between the guide members such that the sides thereof face the guide members 10.
案内手段22.24は互いに上下の関係にあり、上方の
案内手段22はもっばら案内部材10に対して掘削機1
4の本体をその運動時に案内する役割をもち、また下方
の案内手段24は掘削機本体の案内および案内部材10
と掘削機14との間のシェル18が及ばない区域の掘削
という2つの役割をもつ。The guide means 22 , 24 are in a one-on-one relationship with each other, the upper guide means 22 being the most direct of the excavator 1 relative to the guide member 10 .
The lower guide means 24 has the role of guiding the main body of the excavator 4 during its movement, and the lower guide means 24 serves as a guide for the excavator main body and guide member 10.
It has a dual role of excavating the area between the shell 18 and the excavator 14 that cannot be reached.
まず、上方の案内手段22は、第2,3図に示すように

ベースに回転可能に取り付けられた一対の案内ローラ2
8と、該案内ローラの下側にあってベース26に取り付
けられたブラケットに回転可能に支承の案内ローラ30
とから成る。First, as shown in FIGS. 2 and 3, the upper guide means 22 includes a base 26 attached to the casing 20 and a pair of guide rollers 2 rotatably attached to the base.
8, and a guide roller 30 rotatably supported on a bracket attached to the base 26 and below the guide roller.
It consists of
一対の案内ローラ28はいずれもケーシング20の側部
から外方へ伸びる回転軸線を有し、案内ローラ30は案
内ローラ28の回転軸線と直角の方向へ伸びる回転軸線
を備える。Each of the pair of guide rollers 28 has a rotation axis extending outward from the side of the casing 20, and the guide roller 30 has a rotation axis extending in a direction perpendicular to the rotation axis of the guide roller 28.
案内手段22を構成する複数の案内ローラは案内部材1
0の形状に従って種々の配置を取ることができる。A plurality of guide rollers constituting the guide means 22 are the guide member 1
Various arrangements can be taken according to the shape of 0.
図示の例は、案内部材10をH型鋼とした場合に適合す

の回転軸線上に案内ローラを設けることにより、案内部
材各部と案内ローラとの接触および回転によって一層安
定的に掘削機14を昇降案内することができる。The illustrated example is suitable for the case where the guide member 10 is made of H-shaped steel, and depending on the shape of the guide member, guide rollers may be provided on the axis of rotation in other directions to connect each part of the guide member to the guide roller. By contacting and rotating the excavator 14, the excavator 14 can be guided up and down more stably.
上方の案内手段22はもっばら掘削機14の昇降案内の
役割をも、つことから、ローラによらない非回転の案内
子(図示せず)をもって構成することもできる。Since the upper guide means 22 mainly serves to guide the excavator 14 up and down, it can also be configured with a non-rotating guide (not shown) that does not rely on rollers.
下方の案内手段24はケーシング20に取り付けられた
鋼製の案内子32からなり、該案内子の外側端には複数
の爪34が取り付けられている。The lower guide means 24 consists of a steel guide 32 attached to the casing 20, with a plurality of pawls 34 attached to the outer end of the guide.
爪34は、第2,3図から明らかなように先端が下向き
となるように配置され、案内子に押え板36により固定
されている。As is clear from FIGS. 2 and 3, the claws 34 are arranged with their tips facing downward, and are fixed to the guide by a presser plate 36.
下方の案内手段は案内作用および案内部材近傍の土砂を
削り落す作用を担う。The lower guide means has a guiding function and a function of scraping off earth and sand near the guide member.
従って、案内子に支承された爪34は、その外縁部が第
1の案内手段を構成する案内ローラの外縁部の直下にあ
って、これらが掘削機14の最大幅寸法を規定するよう
に配置されている。Therefore, the claws 34 supported by the guide are arranged so that their outer edges are directly below the outer edges of the guide rollers constituting the first guide means, and these define the maximum width dimension of the excavator 14. has been done.
掘削時に爪側に削られた土砂が円滑に落下すすように、
案内子32の下側にはバッフル37が取り付けられてい
る。So that the earth and sand scraped by the claw side during excavation will fall smoothly.
A baffle 37 is attached to the lower side of the guide 32.
このバッフル37は第2図でみて爪34の近傍に尖端3
8が位置するようにケーシング側および爪側から傾斜す
る側面形状と、第3図でみて案内子32の下側のほぼ中
央に尖端38が位置するように傾斜する正面形状とを有
する。This baffle 37 has a pointed end 3 near the claw 34 as seen in FIG.
It has a side surface shape that slopes from the casing side and the claw side so that 8 is located, and a front surface shape that slopes so that the tip 38 is located approximately in the center of the lower side of the guide element 32 as seen in FIG.
このバッフル37によれば爪34によって削られた案内
部材近傍の土砂はケーシング側よりむしろ爪側で下向き
の落下を強制され、削土の円滑化が図られる。With this baffle 37, the earth and sand in the vicinity of the guide member scraped by the pawl 34 is forced to fall downward on the pawl side rather than on the casing side, thereby making earth removal smoother.
