(10) 1276734 壓力感測器1 7乃被構成可對上述電腦1 8能輸入上述 盾後部空隙1 2內之壓力。 因此，在實施例1中，可由地面37之電腦18在推進用 千斤頂5之壓力推進速度，加上了盾後部空隙1 2內之壓力 ，而算出應導出於盾後部空隙內之最適宜之滑材量。 換言之，由於實施例1可一面校對對於盾後部空隙1 2 內之滑材導出狀態，並依據推進用千斤頂5之推動速度而 使滑材成爲適宜之量，所以可以實現更順暢之掘削體3及 管構件之推進。 在於管構件4之外周部，突沒（突出·沒入）自如地 設有銷體1 3。 在實施例1中，銷體1 3是可自由突沒地設置於管構件 4A、4B的外周部。 管構件4 A之銷體13係設於轉動環材14。據此，一方 面使轉動環材14旋轉一方面由滑材導出口 7對於盾尾部 空隙1 2內導出滑材，因此在管構件4之全外周部形成滑材 及土壤之混合層，可更順暢地推進掘削體3及管構件4。（ 管周混合工法） 第2圖係表示介置於第5圖所示之管構件4D之間之管 構件4A。該管構件4A上，設有可相對於該管構件4A自由 轉動的轉動環材1 4。該轉動環材1 4上，鑽設有環狀的滑材 導出口 7，並且設有可突沒（突出·沒入）之銷體13。換言 之’轉動環材14係被設置成可連設於環構4A之其他管構 件自由轉動。 -13- (11) 1276734 又，在第2圖至第1 ο圖中，有關於將滑材導出於管構 件4外之機構係省略其圖示。 第6圖、第7圖係圖示了銷體1 3之突沒機構之動作 原理，採用螺栓桿做爲銷體1 3，該螺栓桿係形成螺合於設 於管構件4之內面之母螺牙部1 5的構造。 第8圖、第9圖、第1〇圖，係圖示轉動環材14之迴 旋機構及突沒機構之動作原理（上述第6圖、第7圖之銷 體1 3之突沒機構係別之突沒機構）。 在於管構件4D之內面固著了安裝構件20，而在於此安 裝構件20之先端（第8圖之上端）之軸承21嵌入固定軸 22 ° 在該安裝構件20之中途，設置第1驅動馬達23，而在 此第1驅動馬達23之驅動軸，設置小齒輪24。 轉動環材14可相對於管構件4Α自由轉動地形成嵌合 ，而被嵌合於上述軸22之擺動體25之下端固著於轉動環材 14 ° 在於擺動體25之中途固著了形成有齒條齒之呈半圓狀 、剖面L字狀之齒條齒體26，此齒條齒體26與上述小齒輪 24形成嚙合。 又，擺動體25被設置於第8圖中左側的安裝構件27， 在此安裝構件27內擺動自如地設有銷體1 3，銷體13之先 端係從鑽設於轉動環材14之孔38而突出於轉動環材14之 外側。在此銷體13之基端（第10圖中上側）固著有斜齒輪 28，又在安裝構件27設有嚙合於此斜齒輪28之斜齒輪29 (12) 1276734 之第2驅動馬達30。 又在於銷體13之基端（第10圖中上側）連設有氣缸裝 置3 1之推桿3厂。 符號32係可以將推桿31'之滑動傳遞於銷體13，惟不 會將銷體1 3之轉動傳遞於推桿3厂之卡合部。 圖示於該第8圖、第9圖、第10圖之轉動環材14的轉 動機構及銷體1 3之突沒機構，是由上述所構成，一旦第1 驅動馬達23動作將使小齒輪24轉動，且齒條齒體26擺動 將同時使體25產生擺動，於是轉動環材1 4係可相對於管構 件4A轉動，（惟轉動環材14只相對於管構件4A轉動到 1 80°爲止）。 又，一旦第2驅動馬達30動作，將使斜齒輪29轉動， 因爲斜齒輪28轉動而使銷體1 3也轉動，甚至因汽缸裝置 3 1之推桿3 1'的滑動而使銷體1 3產生滑動，以銷體1 3由轉 動環材1 4之外面而做突出·沒入。 使用上述之第2圖〜第10圖之各構件或各機構，可藉由 鑽設如第1 1圖所圖示之橫坑2，實施良好之管構件4之配 設。 依據第11圖具體的做說明。在使用第6圖、第7圖之 構造之銷體1 3時，將該銷體1 3適當量地突出而將管構件4 推入於橫坑。由於該銷體Π會破壞管構件4之周圍之泥砂 (坑壁16)。所以減輕了管構件4所承受之土壓，又達成周 邊之天然硬土層（坑壁1 6)之泥沙與滑材之混合所以管構 件4等之推進可以良好的進行。 -15- (13) 1276734 再者，使用第8圖、第9圖、第10圖之構造之銷體13 時，除了與上述第6圖、第7圖同樣之方法之外，如在管 構件4之推進中推進情形變差時，即由滑材導出口 7導出 滑材，同時藉氣缸裝置3 1而使銷體1 3連續地突沒且以第2 驅動馬達使銷體1 3轉動，又以第1驅動馬達使轉動環材1 4 轉動，，而使銷體1 3對於管構件4 A而轉動。於是由滑材 而使管構件4之推進變爲良好，同時由銷體1 3、及轉動環 材14之該作用而會破壞管構件4之周圍之坑壁16 (泥砂） 而降低管構件4之外周之坑壁16 (泥砂）的密度，可減輕 管構件4所接受之土壓，所以管構件4等之推進得於良好 的進行。換言之，可藉由銷體13、轉動環材14之作用，使 滑材與管構件4之周圍之坑壁1 6之泥砂被混合，而在管構 件4之外周形成規定厚度之滑材與坑壁1 6 (泥砂）之混合層 ，該混合層係空隙多（鬆散）、土壓小之層，且由於滑材之 存在而成爲與管構件4間之摩擦力小的層，所以管構件4 等之良好之推進得於達成。 再者，由於滑材與坑壁1 6之泥砂形成混合，所以可 防止該滑材被地下水所稀釋、或滑劑擴散至土中之空隙。 結果而言，藉由銷體1 3之存在、銷體1 3之突出·沒 入動作及轉動環材14之轉動而可以達成管構件4之周圍之 坑壁16之泥砂與滑材之混合，於是可以達成釋放由坑壁16 (泥砂）對管構件4之挾緊之壓力、及阻止由滑材之對應部 份（混合層）的流出（散逸）。 再者，由於銷體1 3之存在，可以防止以銷體1 3之突出 -16- (14) 1276734 量爲厚度之管構件4之表面之泥砂，與管構件4成一體地 隨著管構4之推進一齊移動之情形。此時，由於可以調整 銷體1 3由管構件4突出的突出量，更能對應管構件4周圍 之坑壁1 6 (泥沙）的狀態，確實地阻止泥沙隨著管構件4 的推進所產生的移動。 再者，氣缸裝置3 1之動作，並非當管構件4之推進情 形呈不良時才形成動作，亦可隔一定時間地形成間歇性動作 〇 當管構件4被配設成長距離時，亦可透過不實施滑材 之導出之管構件4設置複數個實施滑材之導出之管構件4。 又，在上述狀態下，亦可設置複數個壓力感測器1 7。或亦 可連續地設置實施滑材之導出之管構件。 藉此，即使管構件4之配設距離成爲長距離時，藉由 推進用千斤頂5之壓接推進速度、及以壓力感測器1 7所感 知之壓力的兩個條件來設定位於橫坑2之管構件4外周部 規定位置之最適合的導出量並導出滑材，可以順暢地推進該 管構件4等。 又，各管構件4之任意之滑材導出口 7可同時並列地 控制滑材量。 圖中符號3 4，係表示用來測定由供給泵1 9朝管構件4 內供給之滑材之流量的流量計，符號3 5係表示用於控制供 給泵1 9之動作旋轉數用之變頻器。 ，由電腦1 8所算出之滑材導出量可藉由該電腦丨8對變 頻器35指示，並藉由變更該變頻器35之頻數而改變馬達旋 -17- (15) 1276734 轉數，由供給泵1 9適時地供給適量之滑材。換言之，供給 泵1 9的作動也由電腦1 8所控制，而由滑材導出口 7導出適 當量之滑材。 此時，由設置於滑材供給路徑8 (滑材供給管8)之流 量計3 4所計測之滑材之流量係輸入於電腦1 8。並且將輸入 之滑材的流量予以積算（相加）而做爲資料來蓄積。 如所測出之滑材之流量過大時，將調查滑材供給路8或 分配路經10 (分配管10)等有無漏洩。此時，當滑材之流 量超出限度而過多時將停止滑材之供給。 所測出之滑材之流量過小時，調查在於滑材供給路經8 (滑材供給管8)或分配路徑10 (分配管10)等有無阻塞。 此時如果滑材之流量超過限度而過小時也將停止滑材之供給 〇 又，藉由測定滑材之流量，可調查電動閥9是否正常 地的做動作。 下面依據第1圖說明實施例1之作用。 首先，以推進用千斤頂5推進管構件4時，以速度感 測器36測定該推進用千斤頂5之推動速度，而將該速度輸 入於電腦1 8。 此時，以設於管構件4B之壓力感測器17測定盾後部 空隙1 2內之壓力，並同時將該壓力也輸入於電腦1 8。 依據輸入之推進用千斤頂5的推進速度、及盾後部空 隙12內之壓力，可由電腦18算出滑材導出口 7應導出之 最適宜之滑材量。此滑材之導出量’乃被設定爲’可順暢 -18- (16) 1276734 地由推進用千斤頂5之動作推進掘削體3及管構件4之量 〇 一旦設定應由滑材導出口 7所導出之滑材量，將由電 腦1 8對電動閥9送出訊號，並依據該訊號開閉電動閥9， ' 而由該滑材導出口 7導出上述設定之導出量的滑材。 例如，推進用千斤頂5之推動速度呈一定，而盾後部 空隙1 2之壓力減低時，由於顯示朝盾後部空隙1 2之滑材 的導出量不足，於是將增加該滑材之導出量。 鲁 又，推進用千斤頂5之推動速度一定而盾尾部空隙之 壓力1 2之壓力增加時，由於顯示朝盾尾部空隙丨2之滑材 _ 的導出量過剩，所以減少該滑材之導出量。 又’盾尾部空隙12壓力急上昇，而限界壓力上昇時 _ ，如再進行滑材之導出的話，可能致使滑材供給路經8 ( 滑材供給管8)或分配路徑10 (分配管1〇)等破損，因此 停止滑材之導出。此時，停止滑材之導出步驟後，如盾尾 部空隙之壓力降到一定壓力時即再開始滑材之導出。 ® 由於實施例1係採取上述之構成及方式，所以並非只 依據滑材之壓力來控制滑材之導出量，而因應於使管構件 等推進之推進用千斤頂的壓接推進速度而將適當量之滑材 導出於坑壁1 6與管構件4之間’所以即使例如在將掘削 體及管構件推進入坑壁之中途，發生坑壁崩塌等致導出於 該坑壁與管構件之間之滑材的壓力變化，仍然不會發生該 滑材之導出量之不足而導致管構件等不能推進之事態’據 此，可以實現順暢之管構件4之推進。 -19 - (17) 1276734 再者，在實施滑材之導入之管構件4上，由於將複數 個滑材導出口 7設置環狀，所以可完整地將滑材導出至管 構件4之外周部（即盾尾部空隙1 2)全體。 又，由於以電腦1 8之指示來控制電動閥9進由滑材導 出口 7導出滑材，所以可適宜的由該滑材導出口 7導出滑材 〇 換言之’由於電腦1 8而可以最適宜之狀態實施電動閥 9之開閉之定時（時序）及開口度、動作順序、開口時間， 因此可在最適宜之時序（定時）確實的操作電動閥9，而對 盾尾部空隙12內導出最適宜之量之滑材。 又，雖然電動閥9之開閉可對應個別而產生動作，但亦 可全部一起動作。又雖然電動閥9係設置於每個滑材導出口 7的分配路經10 (分配管10)，但亦可設置於分配管10正 前方之滑材供給路徑8 (分配管8)，有就是指滑材供給路徑 8 (滑材供給管8 )與分配路徑10之分歧部位。 又，由於可藉由壓力感測器17 —面測定盾尾部12內 之壓力一面導出滑材，因此可防止因對管構件4之外周部 有施加過度之壓力而導致管構件4等的破損情形產生。 又，由於可一面測定盾尾部空隙1 2內之壓力一面實施 滑材之導出，所以可避免例如連結於供給泵1 9之軟管發生 破裂之事態等。 再者，如果將壓力感測器17設置於管構件4(：之滑材 導出口 7時，可利用既有之滑材導出口 7,據此，由於不需 設置壓力感測器的孔，故可降低該部分的成本。 -20- (18) 1276734 又，由於壓力感測器1 7可在管構件4之配設方向上設 置複數個，因而可以測出正確之盾尾部空隙1 2的壓力。 再者，在於管構件4之外周部可自由突出/降下地設置 銷體1 3，再加上管構件4A上設置了可相對於該管構件4A 自由轉動的轉動環材1 4，所以可確實的均等化該導出於管 構件4A之外周部之滑材，因此可以確實地實現管構件4等 之順暢的推進。 又，在於掘削體3之後方連設有多數（長距離）的管 構件4時，如上述所述地配設複數個實施滑材之導出之管 構件4，可在管構件4之外周部均等地良好地配設滑材，並 實現順暢確實之推進。 又，做爲管構件4而採用連接箍（接頭箍：特別是鋼 製箍也可以）。換言之，設於實施例1之管構件4的導出 滑材用之機構，亦可直接設置於連接箍。 在上述的狀態下，可提供一種由電腦1 8之控制而朝盾 尾部空隙1 2導出滑材之導出機構的簡便裝置。此外，即使 在推進過程中或完竣之後也能直接活用鋼製箍。 又，在實施例1中，雖然係例示了在實施滑材之導出之 管構件4的後方，連設了不實施滑材之導出之管構件4之 構成’但亦可採用連設實施滑材之導出之管構件4之方式 。此時，例如亦可在管構件4A之後方連設管構件4B，或 交互地連設管構件4A及管構件4B。 [實施例2] -21 - (19) 1276734 依據附圖說明本發明之實施例2。 實施例2如第12圖所示地，是將推進用千斤頂5之壓 接推進速度及壓力感測器1 7所測定之盾尾部空隙1 2之壓 力之輸入於電腦1 8，由該電腦1 8所算出之規定之滑材導出 量，並非以電動閥9而是藉由設置於管構件4內之注入泵 11之控制來導出，而使管構件4等順暢地推進之方法（中 央控制）。 換言之，實施例2係在實施滑材之導出之管構件4的 滑材導出口 7設置有注入泵11。 具體的說，注入泵11係設置於由做爲主管之滑材供給 路經8 (滑材供給管8)分歧而對各滑材導出口 7供給的分 配路經（分配管10)。 於實施例2中，在各滑材導出口 7分別設有注入泵11 〇 該注入泵11，係由速度感測器36將推進用千斤頂5之 推進速度輸入電腦1 8，並依據電腦3 8所算出之訊號而實 施規定動作，藉此，形成可調整由滑材導出口 7導出滑材之 導出量的結構。又，所謂由上述電腦1 8所算出之訊號係 ，與實施例1同樣，都是可在管構件44之外周部導出最適 當量之滑材之訊號。 換言之，，注入泵1 1係依據來自電腦1 8之訊號，分別 控制每個注入泵1 1的動作及停止、馬達旋轉數、動作順序 、及動作時間。 在實施例2中，與實施例1同樣，以推進用千斤頂5之 -22- (20) 1276734 壓接推進速度加上盾尾部空隙內之壓力’而由地面3 7之電 腦1 8將導出於盾尾部空隙1 2內之滑材之量設定爲最適當之 量。 藉此，由於可以一面檢驗對於盾尾部空隙1 2內之滑材 之導出狀態，一面依據推進用千斤頂5之壓接推進速度導 出滑材之適量之量，所以可以實現更順暢之管構件4等之 推進。再者，當盾尾部空隙1 2內之壓力降低時滑材的導出 量則設成較多。 又，符號3 3是在管構件4內暫時地貯存一定量之滑材 之貯留槽。 實施例2中雖配設了貯留槽3 3，但亦可不使用該貯留 槽3 3而直接連結於滑材供給路徑8 (滑材供給管8)來供給 滑材。 又其他的部分即與實施例1相同。 實施例2係採用上述之構成，所以可依據盾尾部空隙 12之壓力及推進管構件4等之推進用千斤頂5之壓接推進速 度，由電腦1 8僅控制可良好推進之管構件4等的適宜量之 滑材，並藉由控制注入泵1 1就可以確實的導出於盾尾部空 隙1 2內，所以可以實現管構件4等之順暢圓滑之推進。 [實施例3] 依據附圖說明本發明之實施例3。 實施例3係有關於如第13圖所示，設有可以使電動閥9實 現指定動作之動作控制裝置39，由此動作控制裝置39之控制 -23- (21) 1276734 來實施電動閥9之開閉控制，同時依據推進用千斤頂5之推 進速度來控制供給泵1 9，調整管構件4內之滑材之供給量， 調整由滑材導出口滑材之導出量，由而使管構件4等順暢地 推進之推進工法。 換言之，實施例3乃並非來自電腦18之訊號來實施電腦 閥9之開閉控制，而是由來自動作控制裝置39之訊號來動作 控制設於滑材之導出之管構件4之滑材導出口 7之電動閥9(分 散控制）。 動作控制裝置39係採用定序器39。 該定序器39係設定爲電動閥9得以規定之定序、動作順 序、開口度、開口時間等實施開閉控制。 具體的說，由定序器39來規定各個之滑材導出口 7之開 口時間（秒單位），由而控制電動閥9依序注入滑材。 換言之，實施例3乃藉由依據推進用千斤頂5之壓接推 進速度來控制供給泵1 9由而將適當量之滑材供給於管構件4 內，同時以定序器39而以規定開閉控制電動閥9，由而對於 管構件4之外周部可以導出適當量之滑材地被構成者。 又，實施例3除了不設置壓力感測器1 7之點以外，係與 實施例1相同。又，如實施例1、2般地’亦可在於管構件4D 設置壓力感測器1 7，而依據該壓力感測器1 7所感知之壓力 及速度感測器3 6所感知之千斤頂速度的雙方條件’而將規定 量之滑材供給於管構件4內’而以定序器3 9來導出控制所供 給之滑材來構成。 由於實施例3係採取如上述之構成’所以可依據推進用 千斤頂5之壓接推進速度來動作控制供給泵1 9，而對於管構 -24- 1276734 (22) 件4內供給規定量之滑材，並由於依據來自定序器39之訊號 來開閉控制電動閥9，而由滑材導出口 7導出可使管構件4良 好地推進之規定量之滑材，故成爲可順暢地推進管構件4等 之劃時代的減輕管周摩擦之推進工法。 再者，本發明並非侷限於實施例1至實施例3，各構成要 件之具體的構成係可適當地設計變更。 【圖式簡單說明〕 第1圖表示實施例1之整構成（中央控制）之說明圖。 第2圖表示實施實施例1之滑材之導出之管構件之說明 斜視圖。 第3圖表示與實施例1之第2圖之管材不同之別的滑材之 導出之管構件之說明斜視圖。 第4圖表示不實施實施例1之滑材之導出之管構件之說 明斜視圖。 第5圖表示不實施實施例1之第4圖之管材不同之滑材之 導出之管構件之說明斜視圖。 第6圖表示實施例1之銷體之動作原理之說明圖。 第7圖表示實施例1之銷體之動作原理之放大說明剖面圖 〇 第8圖表示實施例1之轉動環材之迴旋機構及銷體之突沒 機構之動作原理之說明剖面圖。 第9圖表示實施例1之轉動環材之迴旋機構及銷體之突 沒機構之動作原理之說明剖面圖。 第1 0圖表示實施例1之轉動環材之迴旋機構及銷體之 -25- 1276734 (23) 突沒機構之動作原理之說明剖面圖。 第1 1圖表示實施例1之管周混合工法之實施形態之說 明圖。 第12圖表示實施例2之整體構成（中央控制）之說明· 圖。 第13圖表示實施例3之整體構成（分散控制）之說明 圖。 (符號說明） 1 工作井 2 橫坑 3 掘削件 4 管構件 4A 管構件 5 推進用千斤頂 7 滑材導出口 8 滑材供給路徑 9 閥 11 注入泵 12 盾尾部空隙 13 銷體 1 4 轉動環材 1 5 母螺牙部 16 坑壁（夭然硬土層） 17 壓力感測器 -26- (24)1276734 18 電 腦 19 供 給 泵 20 安 裝 構 件 2 1 軸 承 22 1 軸 23 第 1 驅 動 馬 達 24 小 齒 輪 25 擺 動 體 26 齒 條 髀 27 安 裝 構 件 28 針 齒 輪 29 針 齒 輪 30 第 2 驅 動 馬 達 3 1 活 塞 裝 置 3 1 f 推 桿 32 卡合部 3 3 貯 留 槽 34 流 量 計 35 變 頻 器 36 速 度 感 測 器 37 地 面 3 8 孔 39 定 序 器(2) 1276734 However, when the sliding material is led into the gap of the tail of the shield, if the collapse of the pit wall occurs, or the arrangement of the pressure sensor is blocked, the pressure sensed in the gap of the shield tail occurs. If the change is made, the derivation may be stopped in a state in which the sliding material of the shield tail gap is insufficient, and the pipe member may not be smoothly pushed in some cases. Therefore, the previous example cannot be said that the pipe member can be well disposed. Inside the pit. The present invention provides a method for smoothly and smoothly advancing a cutting device even if the fluid pressure in the gap of the shield tail is changed due to the collapse of the pit wall or the like, and the optimum amount of the sliding material can be led out into the gap of the shield tail portion. Or the propulsion method of the pipe component. (Means for Solving the Problem) The gist of the present invention will be described below with reference to the drawings. 1 The propulsion method method for reducing the friction of the pipe peripheral wall of the present invention, firstly drilling a working well (1), and introducing the excavation body (3) and the pipe member from the peripheral wall of the working well (1) by advancing the jack (5) 4) a drilling method for implementing the horizontal pit (2) and a propulsion method for arranging the tubular member (4) for the horizontal pit (2), characterized in that: when the tubular member (4) is advanced, the sliding material is led to the pit wall (16) A propulsion method for controlling the friction of the pipe wall between the outer peripheral portion of the pipe member (4) and the pushing amount of the sliding member based on the pushing speed of the pushing jack (5). Moreover, the propulsion method for reducing the friction of the peripheral wall of the pipe as described in the first paragraph of the patent application 'where the pipe member (4) is adopted: the implementation of the derivation of the sliding material (5) 1276734 [Embodiment] Referring briefly to the drawings The embodiments of the present invention and the effects thereof will be appropriately described. For example, when the jack 5 advances the pipe member 4 at a rapid crimping advancement speed, the pipe member 4 will advance rapidly. At this time, if the amount of the sliding material that is led between the pit wall and the outer peripheral portion of the pipe member 4 is insufficient, that is, when the leading speed of the sliding material does not match the pushing speed of the pipe member 4, the sliding material may not be sufficient. It is introduced between the pit wall 16 and the outer peripheral portion of the pipe member 4. Therefore, the frictional resistance cannot be alleviated, so that the excavation body 3 and the pipe member 4 cannot be smoothly advanced. In view of the above, the present invention can control the amount of the sliding material to be controlled into a larger amount when the pushing speed of the pushing jack 5 is fast, and the speed is adjusted to be less when the pushing speed is slow. the amount. According to this, since the amount of the sliding material that is led between the pit wall 16 and the outer peripheral surface of the pipe member 4 is appropriately controlled based on the press-advancing speed of the pushing jack 5 as a reference, the sliding material can be used. The action of the excavation body 3 and the pipe member 4 is smoothly advanced. Since the present invention adopts the above configuration, for example, during the advancement of the excavation body 3 and the pipe member 4 to the pit wall 16, even if the pit wall 16 is collapsed or the like, it is led to be led between the pit wall 16 and the pipe member 4. The pressure of the sliding material changes, and the smooth advancement of the pipe member 4 or the like can still be achieved. [Embodiment 1] Embodiment 1 of the present invention will be described with reference to the drawings. -8- (6) 1276734 In the first embodiment, a working well (vertical pit) 1 is drilled first, and a horizontal hole 2 is drilled after the excavation body 3 and the pipe member 4 are introduced from the peripheral wall of the working well 1 by the push jack 5; The propulsion method of the pipe member 4 is disposed in the horizontal pit 2, and the sliding material is led between the pit wall 16 and the outer peripheral portion of the pipe member 4 during the advancement of the pipe member 4 (hereinafter referred to as "the shield tail gap 1 2 ”), and the amount of the sliding material is controlled by using the pushing speed of the pushing jack 5 as a reference. Further, in the first embodiment, an implementation method (central control) for controlling the amount of discharge of the sliding material by pushing the pushing speed of the jack 5 as a reference is performed by a computer. That is, as shown in Fig. 1, a speed sensor 36 for measuring the press-pushing speed (stroke) of the push jack 5 is provided at the push jack 5 disposed in the vertical pit 1, and The operation of the jack 5 is connected to the pipe member 4 of the excavation body 3 disposed in the horizontal pit 2, and a sliding material supply path 8 for supplying the sliding material to the pipe member 4 is provided, and is disposed on the floor 37. The computer 18 that leads to the amount of slip material exported to the shield tail space 1 2 is set in accordance with the pressure advancement speed of the push jack 5 measured by the speed sensor 36. Further, a supply pump 19 for supplying the sliding material to the pipe member 4 through the slip material supply path 8 is provided on the floor 37. The supply pump 19 is controlled by the computer 18 as will be described later. The rake machine 3 is, for example, a shield machine or the like. The pipe member 4 connected to the excavator 3 is driven by the action of the push jack 5 described above, and the pipe member 4 is sequentially pushed in the rear portion of the pipe member 4. The pipe member 4 is a pipe member that is used to perform the discharge of the sliding material. 4, or false - 9 - (7) 1276734 The sliding member of the tube member 4. The pipe member 4 for implementing the sliding material is a pipe member 4A having a rotating ring member 14, and a pipe member 4B having no rotating ring member 14. That is, a plurality of sliding material outlets 7 for guiding the sliding material out of the pipe member 4 are provided in the pipe members 4A, 4B. Specifically, in the pipe members 4A and 4B, as shown in Figs. 2 and 3, the sliding material outlet 7 is formed in a plurality of rings. The reason why the sliding material outlet port 7 is provided in a ring shape is to completely guide the sliding material to the outer periphery of the pipe member 4. In other words, since the sliding material is disposed in a ring-shaped sliding material outlet port 7 so that the sliding material is uniformly filled on the entire outer circumference of the pipe member 4, the pipe member 4 can be favorably advanced. The pipe member 4 which is not subjected to the discharge of the sliding material is a pipe member 4C (see Fig. 4) provided with the sliding material outlet port 7 and a pipe member 4D (see Fig. 5) in which the sliding material outlet port 7 is not provided. As shown in Fig. 4, the pipe member 4C is provided with a sliding material outlet port 7 at two places in the longitudinal direction of the pipe member 4C. Further, the sliding member outlet 7 of the pipe member 4C may be provided in one place or in two or more places. In other words, the pipe member 4C is used in a state where the sliding material is not led out by the sliding material outlet port 7. Further, the discharge of the sliding material from the sliding material outlet port 7 of the pipe member 4 C can be carried out as needed. In other words, the pipe member 4C can also be applied to the pipe member 4 as the above-mentioned sliding material. In the first embodiment, as shown in Fig. 1, a pipe member 4d (or 4 C) which does not lead to the sliding material is connected to the rear side of the pipe member 4A (or the pipe member 4B) from which the sliding material is led. -10- (8) 1276734 Pipe fittings 4 are exhaust pipes, ducted pipes (ducUle P1pe), follow-up pipes, special pipes for the export of sliding materials, and so on. Further, as long as the sliding material can be led out of the pipe member 4, the pipe member 4 which is a solid or a sliding material can be used as the pipe other than the exhaust pipe, for example, a connection collar can also be used. use. Further, the number of the sliding material outlets 7 of the pipe members 4A, 4B, and 4C is appropriately set depending on the size of the pipe member 4 or the soil quality of the pit wall 16. The sliding material outlet 7 of the pipe member 4 for carrying out the sliding material is provided with a valve 9, by which the amount of discharge of the sliding material led out by the sliding material outlet 7 can be adjusted. Further, in the present embodiment, the illustration of the valve 9 is omitted in the second and subsequent drawings. In the first embodiment, the valve 9 is an electric valve 9 that is operated by energization. Further, in the first embodiment, the electric valve 9 is used as the valve 9, but an electromagnetic valve may be employed. Further, a valve that is activated by air such as a cylinder valve or a hydraulic valve that operates with oil pressure may be used. The electric valve 9 is disposed in a distribution path (distribution pipe 10) for supplying the sliding material to each of the sliding material outlets 7 by the main material sliding material supply path 8 (sliding material supply pipe 8). Further, the sliding material supply path 8 and the distribution path 10 are constituted by piping, a hose, or the like. The electric valve 9 is configured such that the speed sensor 36 feeds the crimping advance speed of the push jack 5 to the computer 8 and performs a predetermined operation based on the signal calculated by the computer 18 to adjust the slip from the sliding material outlet. 7 The amount of slip material exported. 1276734 Ο) In other words, the electric valve 9 is based on the signal from the computer 18, and performs switching control such as timing, operation sequence, opening degree, opening time, and the like. Further, in the first drawing, in order to make the drawing easier to understand, the connection line (signal line) of the connection computer 18 and the electric valve 9 is disposed outside the tube, but is actually disposed in the tube member 4. . The pipe member 4 which is not subjected to the discharge of the sliding material is provided with a pressure sensor 17 for measuring the pressure in the gap 12 of the rear portion of the shield. In other words, in the case where the pressure sensor 17 is provided in the pipe member 4C, the pressure sensor side 17 is provided in the sliding material outlet 7 previously provided in the pipe member 4C. Therefore, since the pressure sensor 17 is provided by using the provided hole, it is not necessary to additionally drill a hole for mounting the pressure sensor, and the cost of the portion can be reduced. Further, in the case where the pressure sensor 17 is to be provided on the pipe member 4D which is not provided with the sliding material outlet port 7, the hole for the pressure sensor 17 is drilled, and the pressure sensor 17 is provided in the hole. In other words, a pressure sensor is provided for a pipe member having a hole (a perforated pipe) by using the hole. For a pipe member (non-porous pipe) that does not have a hole, a hole is drilled and a pressure sensor is provided in the hole. Further, the pressure sensor 17 may be provided not on the sliding material outlet 7 of the pipe member 4 but on the outer circumferential surface of the pipe member 4. In other words, for example, the pressure sensor 17 may be provided in the outer periphery of the pipe member 4D which does not have the slide material outlet port 7. The connection (wire, etc.) that causes the pressure sensor to function at this time can also be guided by the connection collar. -12 - (10) 1276734 The pressure sensor 17 is constructed to allow the above-mentioned computer 18 to be input into the pressure in the rear gap 1 2 of the shield. Therefore, in the first embodiment, the pressure of the pushing jack 5 can be increased by the computer 18 of the floor 37, and the pressure in the rear gap of the shield is added to calculate the optimum slip which should be derived in the rear space of the shield. Material quantity. In other words, since the first embodiment can correct the sliding material in the gap 1 2 in the rear of the shield and make the sliding material suitable according to the pushing speed of the pushing jack 5, a smoother body 3 can be realized. The advancement of the pipe member. In the outer peripheral portion of the pipe member 4, the pin body 13 is provided freely (projected and immersed). In the first embodiment, the pin body 13 is provided at the outer peripheral portion of the pipe members 4A, 4B so as to be freely projecting. The pin body 13 of the pipe member 4A is provided to the rotating ring member 14. According to this, on the one hand, the rotating ring material 14 is rotated, and on the one hand, the sliding material is led out from the sliding material outlet port 7 in the gap portion 12 of the shield tail portion, so that a mixed layer of the sliding material and the soil is formed on the entire outer peripheral portion of the pipe member 4, and The excavation body 3 and the pipe member 4 are smoothly advanced. (Circumferential Mixing Method) Fig. 2 shows the pipe member 4A interposed between the pipe members 4D shown in Fig. 5. The pipe member 4A is provided with a rotating ring member 14 which is freely rotatable relative to the pipe member 4A. The rotating ring member 14 is drilled with an annular sliding material outlet 7 and is provided with a pin body 13 which can be protruded (projected and immersed). In other words, the rotating ring 14 is arranged to be freely rotatable by other tube members that can be attached to the ring structure 4A. -13- (11) 1276734 Further, in the drawings from Fig. 2 to Fig. 1, the mechanism for guiding the sliding material out of the pipe member 4 is omitted. Fig. 6 and Fig. 7 are diagrams showing the principle of operation of the protruding mechanism of the pin body 13. The bolt rod is used as the pin body 13 and the bolt rod is screwed to the inner surface of the pipe member 4. The structure of the female screw portion 15. Fig. 8, Fig. 9, and Fig. 1 are diagrams showing the operation principle of the turning mechanism and the protruding mechanism of the rotating ring member 14 (the protruding mechanism of the pin body 13 of Fig. 6 and Fig. 7 described above) The sudden organization). The mounting member 20 is fixed to the inner surface of the pipe member 4D, and the bearing 21 at the tip end (the upper end of Fig. 8) of the mounting member 20 is fitted into the fixed shaft 22°. In the middle of the mounting member 20, the first driving motor is disposed. 23, and the pinion gear 24 is provided on the drive shaft of the first drive motor 23. The rotating ring material 14 is rotatably formed with respect to the pipe member 4, and is fixed to the rotating ring material 14 at the lower end of the rocking body 25 fitted to the shaft 22, and is fixed in the middle of the rocking body 25. The rack teeth are semi-circular and L-shaped rack teeth 26, and the rack teeth 26 are engaged with the pinion 24. Further, the rocking body 25 is provided on the mounting member 27 on the left side in Fig. 8, and the pin body 13 is swingably provided in the mounting member 27, and the tip end of the pin body 13 is drilled from the hole drilled in the rotating ring material 14. 38 protrudes from the outer side of the rotating ring material 14. At the base end (upper side in Fig. 10) of the pin body 13, a helical gear 28 is fixed, and the mounting member 27 is provided with a second drive motor 30 that meshes with the helical gear 29 (12) 1276734 of the helical gear 28. Further, at the base end of the pin body 13 (upper side in Fig. 10), a pusher 3 factory of the cylinder device 31 is connected. Reference numeral 32 is that the sliding of the push rod 31' can be transmitted to the pin body 13, but the rotation of the pin body 13 is transmitted to the engaging portion of the push rod factory. The rotation mechanism of the rotating ring material 14 and the protruding mechanism of the pin body 13 shown in Figs. 8, 9, and 10 are configured as described above, and the first driving motor 23 is operated to cause the pinion gear. 24 rotation, and the rack tooth 26 swings to simultaneously oscillate the body 25, so that the rotating ring 14 is rotatable relative to the tube member 4A (but only the rotating ring 14 is rotated to 180° with respect to the tube member 4A). until). Further, when the second drive motor 30 operates, the helical gear 29 is rotated, because the helical gear 28 rotates, the pin body 13 also rotates, and even the pin body 1 is caused by the sliding of the push rod 3 1' of the cylinder device 3 1 . 3, the sliding is generated, so that the pin body 13 is protruded and immersed by the outer surface of the rotating ring material 14. With the members or mechanisms of Figs. 2 to 10 described above, the arrangement of the pipe member 4 can be carried out by drilling the lateral pit 2 as shown in Fig. 1 . Explain in detail according to Figure 11. When the pin body 13 having the structure of Fig. 6 and Fig. 7 is used, the pin body 13 is appropriately protruded to push the pipe member 4 into the horizontal pit. Since the pin body collapses the mud sand (pit wall 16) around the pipe member 4. Therefore, the earth pressure received by the pipe member 4 is alleviated, and the mixing of the sand and the sliding material of the natural hard soil layer (pit wall 16) is achieved, so that the advancement of the pipe member 4 and the like can be performed well. -15- (13) 1276734 In addition, when using the pin body 13 of the structure of Fig. 8, Fig. 9, and Fig. 10, except for the method similar to the above Fig. 6 and Fig. 7, for example, in the pipe member When the propulsion situation in the propulsion is deteriorated, the sliding material is led out by the sliding material outlet 7, and the pin body 13 is continuously protruded by the cylinder device 31, and the pin body 13 is rotated by the second driving motor. Further, the rotating ring member 14 is rotated by the first drive motor, and the pin body 1 3 is rotated about the pipe member 4A. Then, the advancement of the pipe member 4 is made good by the sliding material, and at the same time, the pin body 16 (mud sand) around the pipe member 4 is broken by the action of the pin body 13 and the rotating ring member 14, and the pipe member 4 is lowered. The density of the pit wall 16 (mud sand) in the outer circumference can reduce the earth pressure received by the pipe member 4, so that the advancement of the pipe member 4 or the like is well performed. In other words, by the action of the pin body 13 and the rotating ring member 14, the sliding material can be mixed with the mud sand of the pit wall 16 around the pipe member 4, and the sliding material and the pit of a predetermined thickness can be formed on the outer periphery of the pipe member 4. a mixed layer of walls 16 (mud sand) which is a layer having a large number of voids (loose) and a small earth pressure, and a layer having a small frictional force with the pipe member 4 due to the presence of the sliding material, so that the pipe member 4 Good progress can be achieved. Further, since the sliding material is mixed with the muddy sand of the pit wall 16, it is possible to prevent the sliding material from being diluted by the groundwater or the lubricant to diffuse into the void in the soil. As a result, by the presence of the pin body 13 , the protrusion/intrusion action of the pin body 13 , and the rotation of the rotating ring material 14 , the mixing of the mud sand and the sliding material around the pit wall 16 of the pipe member 4 can be achieved. Thus, it is possible to release the pressure which is tightened by the pit wall 16 (mud sand) against the pipe member 4, and to prevent the outflow (dissipation) of the corresponding portion (mixed layer) of the sliding material. Furthermore, due to the presence of the pin body 13, it is possible to prevent the mud sand on the surface of the pipe member 4 having the thickness of the pin body 13 from the protrusion -16 - (14) 1276734, and the tube member 4 integrally with the pipe structure 4 The situation of moving forward together. At this time, since the amount of protrusion of the pin body 13 by the pipe member 4 can be adjusted, it is possible to more reliably correspond to the state of the pit wall 16 (sand) around the pipe member 4, and surely prevent the sediment from propelling along with the pipe member 4. The resulting movement. Further, the operation of the cylinder device 31 does not form an operation when the advancement of the pipe member 4 is defective, and an intermittent operation may be formed for a certain period of time. When the pipe member 4 is disposed at a long distance, it is also transparent. The pipe member 4, which does not perform the derivation of the sliding material, is provided with a plurality of pipe members 4 for performing the derivation of the sliding material. Further, in the above state, a plurality of pressure sensors 17 may be provided. Alternatively, the tube member for carrying out the export of the sliding material may be continuously provided. Thereby, even if the arrangement distance of the pipe member 4 becomes a long distance, the setting is located in the horizontal pit 2 by the two conditions of the pressure pushing advancement speed of the jack 5 and the pressure perceived by the pressure sensor 17. The most appropriate amount of the predetermined position of the outer peripheral portion of the pipe member 4 is derived and the sliding material is led out, so that the pipe member 4 or the like can be smoothly advanced. Further, any of the sliding material outlets 7 of the respective pipe members 4 can simultaneously control the amount of the sliding material in parallel. In the figure, reference numeral 4 4 denotes a flow meter for measuring the flow rate of the sliding material supplied from the supply pump 19 to the pipe member 4, and reference numeral 35 denotes a frequency conversion for controlling the number of rotations of the supply pump 19. Device. The amount of sliding material calculated by the computer 18 can be indicated by the computer 丨8 to the inverter 35, and the motor rotation -17-(15) 1276734 number of revolutions is changed by changing the frequency of the frequency converter 35, The supply pump 19 supplies an appropriate amount of the sliding material in a timely manner. In other words, the operation of the supply pump 19 is also controlled by the computer 18, and the appropriate amount of the sliding material is led out by the sliding material outlet 7. At this time, the flow rate of the sliding material measured by the flow meter 34 provided in the slip material supply path 8 (sliding material supply pipe 8) is input to the computer 18. Further, the flow rate of the input sliding material is integrated (added) and accumulated as data. If the measured flow rate of the sliding material is too large, it is investigated whether or not the sliding material supply path 8 or the distribution path 10 (distribution pipe 10) is leaked. At this time, the supply of the sliding material is stopped when the flow rate of the sliding material exceeds the limit and is excessive. When the measured flow rate of the sliding material was too small, the investigation was made as to whether or not the sliding material supply path 8 (sliding material supply pipe 8) or the distribution path 10 (distribution pipe 10) was blocked. At this time, if the flow rate of the sliding material exceeds the limit and the temperature is too small, the supply of the sliding material is stopped. 〇 Further, by measuring the flow rate of the sliding material, it is possible to investigate whether or not the electric valve 9 is normally operated. Next, the action of Embodiment 1 will be described based on Fig. 1. First, when the pipe member 4 is propelled by the push jack 5, the speed sensor 37 measures the pushing speed of the pushing jack 5, and the speed is input to the computer 18. At this time, the pressure in the rear gap 1 2 of the shield is measured by the pressure sensor 17 provided in the pipe member 4B, and the pressure is also input to the computer 18 at the same time. Based on the advancement speed of the input jack 5 and the pressure in the rear gap 12 of the shield, the computer 18 can calculate the optimum amount of slip material to be derived from the slip guide 7 . The amount of the slip material is set to 'smoothly -18- (16) 1276734. The amount of the excavation body 3 and the pipe member 4 is promoted by the action of the push jack 5. Once set, the slip material outlet 7 should be set. The amount of the slip material to be exported is sent to the electric valve 9 by the computer 18, and the electric valve 9 is opened and closed according to the signal, and the slip material of the above-mentioned set amount is derived from the sliding material outlet port 7. For example, when the pushing speed of the pushing jack 5 is constant, and the pressure of the rear gap 1 2 of the shield is reduced, since the amount of the sliding material showing the gap 1 2 toward the rear of the shield is insufficient, the amount of the sliding material is increased. Lu, when the pushing speed of the jack 5 is constant and the pressure of the pressure of the tail of the shield is increased by 12, the amount of the sliding material _ which is displayed in the gap 丨2 of the shield is excessive, so that the amount of the sliding material is reduced. In addition, the 'shield gap 12 pressure rises sharply, and when the limit pressure rises _, if the sliding material is further exported, the sliding material supply path 8 (sliding material supply pipe 8) or the distribution path 10 (distribution pipe 1〇) may be caused. The damage is broken, so the export of the sliding material is stopped. At this time, after the step of deriving the sliding material is stopped, if the pressure of the gap in the tail of the shield drops to a certain pressure, the derivation of the sliding material is started. Since the first embodiment adopts the above-described configuration and method, the amount of the sliding material is not controlled by the pressure of the sliding material alone, and the appropriate amount is applied in accordance with the pressure pushing speed of the pushing jack for advancing the pipe member or the like. The sliding material is led between the pit wall 16 and the pipe member 4, so even if, for example, the excavation body and the pipe member are pushed into the pit wall, the collapse of the pit wall or the like is caused between the pit wall and the pipe member. When the pressure of the sliding material changes, the shortage of the amount of the sliding material is not caused, and the pipe member or the like cannot be pushed forward. According to this, the smoothing of the pipe member 4 can be achieved. -19 - (17) 1276734 Further, in the pipe member 4 for introducing the sliding material, since a plurality of sliding material outlets 7 are provided in a ring shape, the sliding material can be completely guided to the outer peripheral portion of the pipe member 4. (ie, the shield tail gap 1 2) all. Moreover, since the electric valve 9 is controlled by the instruction of the computer 18 to guide the sliding material from the sliding material outlet 7, the sliding material can be appropriately exported from the sliding material outlet 7 in other words, which is optimal for the computer 18. In the state in which the timing (time) of opening and closing of the electric valve 9 and the opening degree, the operation sequence, and the opening time are performed, the electric valve 9 can be reliably operated at the optimum timing (timing), and the outlet of the shield tail portion 12 is optimal. The amount of sliding material. Further, although the opening and closing of the electric valve 9 can be performed in response to an individual, all of them can be operated together. Further, although the electric valve 9 is provided in the distribution path 10 (distribution pipe 10) of each of the sliding material outlets 7, it may be provided in the sliding material supply path 8 (distribution pipe 8) directly in front of the distribution pipe 10, and there is It refers to a branching portion of the sliding material supply path 8 (sliding material supply pipe 8) and the distribution path 10. Further, since the sliding material can be guided while measuring the pressure in the shield tail portion 12 by the pressure sensor 17, it is possible to prevent the pipe member 4 and the like from being damaged due to excessive pressure applied to the outer peripheral portion of the pipe member 4. produce. Further, since the sliding material can be guided while measuring the pressure in the gap 12 of the shield tail portion, it is possible to avoid a situation in which the hose connected to the supply pump 19 is broken. Furthermore, if the pressure sensor 17 is disposed on the sliding member outlet 7 of the pipe member 4, the existing sliding material outlet port 7 can be utilized, whereby the hole of the pressure sensor is not required, Therefore, the cost of the portion can be reduced. -20- (18) 1276734 Further, since the pressure sensor 17 can be provided in a plurality of directions in the arrangement direction of the pipe member 4, the correct shield tail gap 1 2 can be measured. Further, the pin body 13 is provided so that the outer peripheral portion of the pipe member 4 can be freely projected/lowered, and the pipe member 4A is provided with a rotating ring member 14 which is freely rotatable relative to the pipe member 4A. Since the sliding material which is guided to the outer peripheral portion of the pipe member 4A can be surely equalized, the smooth advancement of the pipe member 4 and the like can be surely achieved. Further, a plurality of (long-distance) pipes are connected after the excavation body 3 In the case of the member 4, a plurality of pipe members 4 for guiding the sliding material are disposed as described above, so that the sliding material can be uniformly disposed on the outer peripheral portion of the pipe member 4, and smooth and reliable advancement can be achieved. Connection hoop for pipe member 4 (joint hoop: especially steel hoop In other words, the mechanism for guiding the sliding material provided in the pipe member 4 of the embodiment 1 may be directly disposed on the connecting hoop. In the above state, a gap may be provided which is controlled by the computer 18 toward the tail of the shield. 1 2 A simple device for deriving the mechanism for guiding the sliding material. Further, the steel hoop can be directly used even during or after the pushing. Further, in the first embodiment, the tube for deriving the sliding material is exemplified. The rear side of the member 4 is connected to the configuration of the pipe member 4 which does not perform the derivation of the sliding material. However, the pipe member 4 for guiding the discharge of the sliding material may be connected. In this case, for example, after the pipe member 4A The pipe member 4B is connected, or the pipe member 4A and the pipe member 4B are alternately connected. [Embodiment 2] - 21 - (19) 1276734 Embodiment 2 of the present invention will be described with reference to the drawings. Illustrated is the pressure of the push-pull advancement speed of the push jack 5 and the pressure of the shield tail gap 12 measured by the pressure sensor 17.

The amount of material exported is not set by the electric valve 9 but by The method of smoothly pushing the pipe member 4 or the like by the control of the injection pump 11 in the member 4 (central control). In other words, the second embodiment is the sliding material outlet 7 of the pipe member 4 for implementing the discharge of the sliding material. The injection pump 11 is provided. Specifically, the injection pump 11 is provided in a distribution path that is supplied to each of the sliding material outlets 7 by the sliding material supply path 8 (sliding material supply pipe 8) as the main pipe. In the second embodiment, the injection pump 11 is provided in each of the sliding material outlets 7, and the injection pump 11 is input to the computer 18 by the speed sensor 36.

Further, the signal system calculated by the computer 18 is a signal which can extract an optimum amount of the sliding material in the outer periphery of the pipe member 44 as in the first embodiment. In other words, the injection pump 1 1 controls the operation and stop of each of the injection pumps 1 1 , the number of motor rotations, the sequence of operations, and the operation time, respectively, based on the signals from the computer 18. In the second embodiment, as in the first embodiment, the push-pull speed of the push-up jack 5 - 22 - 1276734 plus the pressure in the gap of the shield tail is derived from the computer 13 of the ground 3 7 The amount of the sliding material in the gap 12 of the shield tail is set to the most appropriate amount. In this way, since it is possible to inspect the amount of the sliding material in the gap between the shield tails and the outer side of the shield, the amount of the sliding material can be derived in accordance with the pressure advancement speed of the push jack 5, so that a smoother pipe member 4 can be realized. Advance. Further, when the pressure in the gap 12 of the shield tail is lowered, the amount of the sliding material is set to be larger. Further, reference numeral 3 3 is a storage tank for temporarily storing a certain amount of the sliding material in the pipe member 4. In the second embodiment, the storage tank 33 is disposed, but the slip material may be directly connected to the slip material supply path 8 (sliding material supply pipe 8) without using the storage tank 33. The other parts are the same as in the first embodiment. In the second embodiment, the above-described configuration is adopted. Therefore, the pressure of the shield tail portion 12 and the pressure advancement speed of the push jack 5 for the propulsion pipe member 4 and the like can be controlled by the computer 18 to control only the pipe member 4 which can be favorably advanced. A suitable amount of the sliding material can be surely guided into the shield tail space 1 2 by controlling the injection pump 1 1 , so that smooth and smooth advancement of the pipe member 4 and the like can be achieved. [Embodiment 3] Embodiment 3 of the present invention will be described with reference to the drawings.

Promote the construction method smoothly. In other words, in the third embodiment, the signal from the computer 18 is not used to implement the opening and closing control of the computer valve 9, but the signal from the motion control device 39 is used to control the sliding material outlet 7 of the pipe member 4 disposed at the sliding material. Electric valve 9 (distributed control). The motion control device 39 employs a sequencer 39. The sequencer 39 is set such that the electric valve 9 is subjected to opening and closing control in a predetermined order, operation order, opening degree, opening time, and the like. Specifically, the opening time (seconds) of each of the sliding material outlets 7 is specified by the sequencer 39, whereby the electric valve 9 is controlled to sequentially inject the sliding material.
