層之地盤狀況亦異。對於此種地盤進行藥液注入時，雖未 圖示，以往乃將注入管單獨、或多數支隔著間隔予以插入 於地盤中，透過該等注入管將注入材料隨著注入台之移上 或移下依序進行注入。 -8 - (2) 【發明內容】 發明應解決之課題 惟，藥液注入時之最大課題卻在對於透水系數小之細 碎砂層的浸透，或對於不同土層所成地盤之均勻浸透。 ' 細碎砂層之透水性，通常爲10_ 3〜1(T 4cm /秒， > 對於如此土層欲避免發生地盤破壞予以進行藥液注入時， 浸透理論上，則非以每分鐘1公升以下〜數公升之低吐出 量進行低壓注入不可。 鲁 然，上述眾知注入工法，係每支注入管各使用一組注 入泵。此種注入方式，由於希望儘量縮短工程期間之經濟 性的面，以及泵浦之性能界限的面，致非將吐出量設定爲 每分鐘10〜20公升不可，故注入壓較高容易引起地盤破 壞。於是，地盤會隆起，或易發生細碎土層之浸透固結不 充分。 又，在對於土層相異地盤之注入，而土層變化時，欲 對應該土層變化予以改變注入速度或控制注入量，實用上 ® 頗佳困難，因此會有某一層之注入液多量擴散，或某一層 僅稍些浸透而已之情況等，在如此注入狀態，易發生無法 獲得鄰接固結體互相之連接性的問題。 · 又，本發明人以前案曾提出特開平12 - 45259號公報 ， 之申請。依據該案，乃在地盤中配置多數注入管，透過該 等多數注入管將地盤改良材料自各自之吐出口予以注入地 盤中時，藉將一套裝備中所具多數單元泵由一驅動源加以 作動之多連裝泵浦將上述改良材料壓入於各注入管，自吐 -9- (3) (3)591161 出口注入於地盤中。 上述眾知技術，由於注入細管自泵浦裝備至注入孔需 要較長距離，致必需使用低粘度且凝固時間較長之注入液 。惟，凝固時間較長之注入液一旦開始脫逸至地表面，或 地盤中粗糙層時，由此無法縮短凝固化時間致不得不中止 注入，而有灌漿在其期間凝固於注入細管等之不妥的問題 又，以一台驅動源同時驅動構成多連裝泵浦之多數單 元泵，且各個吐出口之地盤條件相異，致最適宜注入條件 亦各異，則將所有單元泵以相同條件予以驅動，故對於各 吐出口均欲進行最適宜注入卻不可能。 於是，本發明之目的即如上述所示，在於提供一種可 活用以往所開發對於廣闊地盤之低壓浸透注入灌漿的多點 注入泵之優點，並對應各灌漿注入管之注入狀況，能任意 管理各單元泵之注入速度、注入壓、注入中止或再開、凝 固化時間等，且同時管理多數單元泵之作動以把握管理注 入狀況全體，而將上述眾知技術之缺點予以改良之多點地 盤注入工法及裝置。 本發明之其他目的，乃在於當一次注入之粗糙注入時 ，或注入中凝固化時間較長灌漿開始脫逸時，可注入凝固 化時間較短灌漿加以防止之，而飛躍性的促使多連裝注入 裝置之多點注入的實用性發展。 本發明之其他目的，亦在於提供一種對於透水性較少 細碎土層，或地盤狀況各層不同之地盤，不僅藉吐出量1 公升以下〜數公升/分之可變吐出量可同時或選擇性地達 -10- (4) (4)591161 成最適宜注入，又能進行地盤中之縱向、橫向的立體性注 入’因此，提升對於細碎土層之浸透注入的信賴性，且由 於急速施工亦達成注入工期之縮短，而將上述眾知技術所 存在缺點予以改良之多點地盤注入工法及裝置。 本發明之其他目的，尙在於提供一種不僅可使用溶液 型注入材料，亦能使用懸浮液型注入材料，且藉此可選擇 對應於各注入地點之地盤狀況的任何注入，而將上述眾知 技術所存在缺點予以改良之多點地盤注入工法及裝置。 解決課題之手段 爲達成上述目的，依據本發明之多點地盤注入工法， 係爲將具吐出口之多數支注入管埋設於地盤之多數注入地 點，將地盤改良材料透過該等注入管自多數吐出口同時予 以多點注入之地盤注入工法，其特徵爲：利用由分別獨立 之驅動源所作動且具有由集中管理裝置所控制多數單元泵 之多連裝注入裝置，藉透過導管連接於多數注入管之上述 多數單元泵的作動，將地盤改良材料自多數吐出口透過地 盤中之多數注入地點而進行多點注入。 且，爲達成上述目的，依據本發明之多點地盤注入裝 置，其特徵爲：具有地盤改良材料儲藏槽，與在一套裝備 中由各自獨立之驅動源予以作動且具有由集中管理裝置所 控制多數單元泵並連接於上述儲藏槽之多連裝注入裝置， 與埋設於地盤之多數注入地點，分別透過導管與上述各單 元泵連接之具吐出口的多數支注入管，又上述獨立之多數 -11 - (5) (5)591161 單元泵分別具有由集中管理裝置控制之轉數變速機，上述 導管亦具有流量壓力檢測器所成，而藉此將流量壓力檢測 器之流量及/或壓力資料信號發送至集中管理裝置，且由 各單元泵之作動將儲藏槽中之地盤改良材料以任意的注入 速度、注入壓力或注入量壓送至各注入管，自多數吐出口 同時對地盤予以進行多點注入。 上述轉數變速機則由集中管理裝置加以整批控制。因 此，多數單元泵一方面具有能獨立對於各注入地點進行最 適宜注入之功能，另方面可構成將多數注入地點之注入以 整體加以整批管理的一組注入裝置。 【實施方式】 發明之實施形態 以下，利用所添附圖示詳述本發明。 圖1爲顯示本發明有關裝置之原理圖的說明圖。圖2 爲習知一般所用之活塞泵原理圖。圖3爲將柱塞泵使用爲 單元泵之原理圖。圖4爲將柱塞泵使用爲單元泵之具體例 剖面圖。圖5爲使用爲本發明單元泵之隔膜泵剖面圖。圖 6爲使用爲本發明單元泵之擠壓泵剖面圖，（a)〜（d) 爲顯示各操作狀態之工程圖。圖7爲使用爲本發明單元泵 之蛇形泵剖面圖。圖8爲本發明有關裝置之一具體例流程 圖。圖9爲本發明有關裝置之其他具體例流程圖。圖10 爲本發明有關裝置之更其他具體例流程圖。圖U爲集中 管理裝置之注入監視盤所顯示一具體例圖。圖1 2爲以注 -12- (6) (6)591161 入管使用多少細管之本發明裝置的更其他具體例流程圖。 圖1 3爲本發明有關裝置之更其他具體例流程圖。 圖1所示本發明有關多點地盤注入裝置A，係具有地 盤改良材料儲藏槽2，與在一套裝備中分別由馬達等之獨 立驅動源4所作動且具有集中管理裝置26所連接予以控 制的多數單元泵3,3· · ·3並透過各導管9，9· · ·9 連接於儲藏槽2之多連裝注入裝置5，與埋設於地盤1中 之注入地點6所配置，分別透過導管10，1 〇 ··· 10與 各單元泵3，3· · ·3連接之具吐出口 7, 7· · .7的多 數支注入管8 , 8 · · · 8。 而，上述獨立之多數單元泵3，3· · ·3又具有連接 於集中管理裝置26並受控制之反相器67等轉數變速機 25，25 · · · 25，況且，將單元泵3, 3 · · · 3與注入管 8，8· · ·8連接之導管1〇，1〇· · ·ΐ〇尙具有如同上述 分別連接於集中管理裝置26並受控制之流量壓力檢測器 27，27 · · · 27。注入管8，8 · · · 8卻例如使用Υ形管 桿。 藉上述構成，本發明乃將流量壓力檢測器27之流量 及/或壓力資料信號發送至集中管理裝置26，藉各單元 泵3，3 · ·· 3之作動將儲藏槽2之地盤改良材料以任意 注入速度、注入壓力及注入量壓送至各注入管8，8· · · 8，自多數吐出口 7，7· · .7同時向地盤1中之注入地 點6，6 · · · 6進行多點注入，以形成注入領域34。 本發明所用之單元泵3則可舉活塞泵、柱塞泵、隔膜 -13- (7) (7)591161 泵、擠壓泵、蛇形泵等。該等泵浦除了活塞泵以外，均爲 小型且構造簡單又不易發生故障，因此’不僅溶液型亦可 使用懸浮型灌漿，適於本發明之單元泵。尤其圖3〜圖7 所示各種泵浦爲小型、輕量、低吐出量，且脈動少、構造 簡單又不易發生故障，是故，不僅溶液型改良材料，亦可 使用懸浮型灌漿，是適於本發明之單元泵。 圖2爲活塞泵68之原理圖，活塞泵68係由柱塞12 與介活塞桿13及曲柄軸14連接於該柱塞12而與旋轉軸 1 5 —起轉動之曲柄1 6所構成，如上述，雖高壓且吐出量 大，但脈動大，大型並重量亦重。 圖3爲使用柱塞泵11之本發明有關單元泵3的原理 圖。在圖3，柱塞泵11之柱塞12部分乃往復運動自如地 被內藏於塡充有壓蓋封墊17之缸筒18中，介連桿19連 接於與旋轉軸1 5 —起轉動之曲柄1 6。缸筒1 8介導管20 在柱塞12下方連接於吸引軟管21及輸出軟管22。 且，柱塞泵1 1運轉時，首先，曲柄16與旋轉軸15 一起轉動將柱塞1 2推上往之方向、即上方。此時，圖1 所示地盤改良材料儲藏槽2之地盤改良材料則透過圖3之 吸引軟管21被吸引，並推開球閥23被吸入柱塞12移動 量之相當量。接著，曲柄1 6更與旋轉軸1 5 —起轉動將柱 塞12押下復之方向、即下方。此時，被吸引之地盤改良 材料卻受擠壓關閉球閥23同時推開球閥24，而被送出輸 出軟管22，復介圖1之導管被壓送至注入管8，注入 於地盤1中之注入地點6, 6 · · · 6。 -14 - (8) (8)591161 圖4爲使用柱塞泵11之本發明有關單元泵3的具體 實施例剖面圖，與圖3同樣，柱塞泵1 1之柱塞12部分乃 往復運動自如地被內藏於塡充有壓蓋封墊17之缸筒18中 ，介連桿1 9連接於與旋轉軸1 5 —起轉動之曲柄1 6。缸 筒18介導管20在柱塞12下方連接於吸引軟管21及輸出 軟管22。 在圖4，35爲吸引軟管側之保液槽，由蓋體36予以 覆蓋著。37爲保液槽，與上述同樣被蓋體38所覆蓋著。 39爲蓋體36，38之壓制片。 且，在柱塞泵11運轉時，如上述圖3同樣，首先， 曲柄1 6與旋轉軸1 5 —起轉動將柱塞1 2推上往之方向、 即上方。此時，圖1所示地盤改良材料儲藏槽2中之地盤 改良材料則透過圖3之吸引軟管21被吸引，並推開球閥 23被吸入相當於柱塞12移動量之量，而被保存於保液槽 35。接著，曲柄16更與旋轉軸15 —起轉動將柱塞12押 下復之方向、即下方。此時，被吸引之保液槽3 5中地盤 改良材料卻受擠壓關閉球閥23同時推開球閥24，透過導 管20a，20b繼之保液槽35而被送出輸出軟管22，復介圖 1之導管10被壓送至注入管8，注入於地盤1中之注入地 點 6，6 · · · 6 〇 圖5爲本發明所用之隔膜泵剖面圖，該隔膜泵係具有 以偏心狀裝設於轉軸49，並與轉軸49 一起轉動之搖板50 ，與一端接觸於搖板50之板面50a，另端具有隔膜51且 藉彈簧52之爆發力作動的活塞53，與形成於活塞53之 -15- (9) (9)591161 隔膜51側，而含地盤改良材料之導入口 54及排出口 55 的空間56所構成。 如上述構成之隔膜泵，其構造簡單且小型，當運轉時 ，乃藉轉軸49之轉動致搖板50亦轉動。由於搖板50以 偏心狀裝設於轉軸49，故其板面50a卻斜向轉動。一端接 觸於該板面50a之活塞53即隨著板面50a之斜向轉動， 藉彈簧52之爆發力而左右搖動。此時，活塞53另端之隔 膜51亦呈左右膨縮搖動，藉其搖動力自導入口 54透過閥 體57將地盤改良材料經由閥體58排出至排出口 55，並 反覆該導入及排出作動。又，閥體57，58皆爲單向閥。 圖6爲本發明所用擠壓泵之說明圖。該擠壓泵沿筒體 40內面內藏有泵管41。泵管41內側之泵室44則配置有 以旋轉軸45爲中心轉動自如的兩端具泵滾42，42之轉子 43 ° 且，操作時自泵管41之入口 46向箭頭方向送入地盤 改良材料同時，自圖6 ( a )之狀態藉旋轉軸45之轉動促 使轉子43轉動。此時，如圖6 ( b )所示，轉子43兩端 之泵滾42，42如同擠壓牙膏管子地擠壓泵管41，如圖6 (c )及圖6 ( d )所示將地盤改良材料送出吐出口 47，沿 箭頭方向予以排出。已無改良材料之泵管41卻由橡膠本 身之恢復力回復爲原來之狀態。此時，所達到之吸引力爲 真空度740 mmHg，最大吐出壓力亦呈30 kgf/cm2。此種 擠壓泵能壓送含高粘度、高濃度、固結物之泥漿或泥狀物 -16- (10) (10)591161 圖7爲本發明所用蛇形泵之說明圖，該蛇形泵係由具 兩條螺紋之內螺絲的定子59，與接觸於該定子5內面被 轉動自如予以裝設，並具有其一半螺距之一條螺紋的轉子 60，與容納該等定子59及轉子60之殼體61，與將地盤改 · 良材料自殼體61之一端63導入於定子59及轉子60間的 . 注入口 62，與將該地盤改良材料自殼體61之另一端64 予以排出之排出口 65所構成。 即，圖7之泵浦，基本上由固定於殻體61之定子59 φ 及蛇形狀之轉子60所構成。定子59有兩端以特殊雙重陰 螺紋狀被切割呈半圓形短溝，而單重陽螺紋狀轉子60在 其內側保持偏心距離e mm自轉，且擬轉動於定子59中心 周圍。惟，定子59由短溝形成牆壁，致在〇。地點進行上 下運動，在定子59之90°地點變爲左右運動。亦即，自 正面觀看轉子60，如促使沿左轉進行兩旋轉時，地盤改 良材料則在定子59內之空隙66前進，透過導管10被導 入於未圖示之注入管。 · 定子59與轉子60之關係，卻是每一階段無論在何種 轉動位置均能有效地封鎖自入口至出口（排出口 65 )之 流動，且能順暢地進行連續作用。如此，由於螺紋面完全 · 咬合，致轉子60轉動時，猶如活塞在無限之缸筒沿單向 緩慢地進行擠出並無脈動，又取定子59之任何剖面液量 亦均等，吐出量對應轉動速度經常呈一定。亦即，蛇形栗 之優點爲，（1)呈連續壓送構造，肅靜又無脈動，（2) 對應轉數能確保所定容量之吐出，（3 )無閥體機構，因 -17- (11) (11)591161 此高粘度、高濃度之地盤改良材料混入氣泡，亦能予以移 送。（4 )由於能瞬間正轉、停止、逆轉，故能與自動控 制裝置作連動。（5 )定子59與轉子60之更換簡單等。 上述所示單元泵，通常將5〜100台爲一組以構成多 連裝注入裝置，在一組中，將該等單元泵以縱、橫或立體 予以排列。該等單元泵皆分別由馬達等之驅動源加以作動 。且，各驅動源藉集中管理裝置所控制之反相器等轉數變 速機而作動。因此，一套裝備中之多連裝注入裝置，將獨 立之多數單元泵爲避免由於各自驅動源之作動而產生搖動 、變形或彎曲地，以台座、框體等支承體支撐予以配置， 或予以集成至爲需要。 在本發明，例如將30cmx30cmx0.2cmm之單元栗3， 以橫向4個、長向4個、垂直方向3個，由框體等支承體 支撐予以配置或予以集成時，乃能將48個單元泵3形成 爲最小1.2m xl.2mx 0.9m體積之多連裝注入裝置5。因此 ，本發明之連裝注入裝置能由48個單元泵構成，則將全 體匯集爲容量小，又簡潔的一體化之一組注入裝置。於是 一組多連裝注入裝置如以單元泵使用柱塞泵時，卻呈吐出 壓力於50HZ爲4〜7 Mpa，吐出量於50HZ爲1〜7公升/ 分鐘，體積爲 30cmx 30cmx 20cm之小型。且，由中央集 中管理室之指示促使單元泵自吐出口 7以吐出量1〜7公 升/分鐘，藉反相器對於所定注入地點保持最適宜注入速 度、注入壓力，更由集中管理室將自多數吐出口（例如50 個吐出口）之全體注入，整批管理其全吐出量處於（1〜7 -18- (12) (12)591161 )x 50=50〜350公升/分鐘之範圍，而可進行低吐出量 之粒子間浸透，況且能由於急速施工以致縮短工期。 圖8爲使用保持有A液吸排部3a與B液吸排部3b之 單元泵3，3 ··· 3的本發明裝置流程圖。在圖8，除了 以地盤改良材料儲藏槽2使用A液用槽2a及B液用槽2b ，以單元泵3使用具有介導管9連結於A液用槽2a之A 液吸排部3a及介導管9連結於B液用槽2b之B液吸排部 3a之外，其餘與圖1相同。且促使單元泵3之自A液吸 排部3a與B液吸排部3b的A液、B液呈所定比率及所定 流量，而各A液、B液共用之驅動源4與轉數變速機25 即作動。 使用上述本發明裝置，透過注入管8之吐出口 7將地 盤改良材料多點注入於地盤1之多數注入地點6 , 6 · · • 6時，係將自槽2a之A液及自槽2b之B液分別透過多 連裝注入裝置5之各單元泵3，3· · ·3，個別予以導入 注入管8，8 ··· 8使其合流，同時擠壓注入於地盤1之 多數注入地點6，6 · · · 6。 圖9及圖1 0分別爲本發明有關裝置之其他具體例流 程圖，基本上具有地盤改良材料儲藏槽2、多連裝注入裝 置5、多數注入管8。地盤改良材料儲藏槽2由Α液用槽 2a及B液用槽2b所成，且呈將該等槽中之A液及B液分 別導入注入管8，加以合流之構造。又，針對圖9，在導 管1 〇合流A液及B液後，將合流液壓送至注入管8，自 吐出口 7注入於注入地點，圖10卻在地盤1之注入地點 -19- (13) (13)591161 6配設兩支注入管8，8，對該等兩支注入管8，8分別壓 送A液及B液，由吐出口 7注入於注入地點後，促使在 地盤1中合流反應，或將不同型式改良材料同時或以時間 差予以注入，而兩者相異。此時，將兩支注入管8，8分 別設於距離隔開之個別注入地點6，由各自之吐出口 7向 地盤1中注入A液、B液，使該等在地盤1中合流，予以 反應亦可。 多連裝注入裝置5在一套裝備中具有多數獨立之單元 栗3, 3· · ·3同時，將該等單元栗3, 3· · .3分別由 馬達等獨立驅動源4以一組注入裝置藉一集中管理裝置 26加以一起作動，且介導管9 , 9 ··· 9予以連接於A 液用槽2a及B液用槽2b。該等單元泵3，3· · ·3雖5 組以上如圖9及圖10所示以橫排被多連裝，惟沿未圖示 之縱排予以排列亦可。又，以該等單元泵3，3 · · · 3之 具體例，可使用圖3及圖4所示柱塞泵1 1或圖5之隔膜 栗、圖6之濟壓栗、圖7之蛇形栗等。 注入管8之前端具有吐出口 7，且在地盤1之多數注 入地點6，6 · · · 6埋設多數支，分別連接於通至Α液用 槽2a之單元泵3, 3· · ·3及通至B液用槽2b之單元泵 3 , 3 · · · 3 〇 況且，上述獨立之多數單元泵3，3· · ·3分別具有 轉數變速機25, 25· · ·25。該等轉數變速機25，25· • · 25分別連接於集中管理裝置26 (圖中以點線表示） 並受其控制。其結果，Α液用槽2a及Β液用槽2b中之地 -20 -

The injection of the injection pipe is simultaneously injected through most of the injection pipes. Therefore, the reliability of the infiltration injection of the finely divided soil and layers can be improved, and the multi-site site injection method and device can be shortened due to the rapid construction. . Here, the so-called site improvement materials are injection materials for consolidation of the site that can strengthen or even stop weak water sites, industrial waste, etc., injection materials for the consolidation of pollution substances, which can prevent leakage of harmful substances from pollution substances. Consolidation materials for water layer formation, injecting medicinal materials containing chemical substances required for pollution-free substances, or heavy metal fixing materials required for chemical passivation of heavy metals. φ [Prior art] Through hanging, due to the different water permeability coefficients or porosity of each layer of the site, the conditions of the site of each-layer are also different. When injecting liquid medicine into this kind of site, although not shown, conventionally, the injection pipe was inserted into the site alone or in large numbers at intervals, and the injection material was moved along with the injection table through these injection pipes or Move down and inject sequentially. -8-(2) [Summary of the Invention] Problems to be Solved by the Invention However, the biggest problem when injecting a medicinal solution is the permeation of a fine sand layer with a small water permeability coefficient, or uniform permeation of a site formed by different soil layers. 'The water permeability of the finely divided sand layer is usually 10_ 3 ~ 1 (T 4cm / sec, > For the soil layer to avoid the destruction of the site and inject the liquid medicine, in theory, the penetration is not more than 1 liter per minute ~ It is not possible to perform low-pressure injection with a low output of several liters. Lu Ran, the well-known injection method described above uses a set of injection pumps for each injection pipe. This injection method is intended to shorten the economical aspect of the project as much as possible, and The performance limit of the pump must not be set to 10 to 20 liters per minute, so high injection pressure is likely to cause damage to the site. Therefore, the site will bulge, or it will be prone to infiltration and consolidation of fine soil layers. In addition, when the soil layer is injected differently, and the soil layer changes, it is difficult to change the injection speed or control the injection volume in response to the soil layer change. Practically, it is very difficult, so there will be a certain layer of injection liquid. A large amount of diffusion, or a case where only one layer is slightly penetrated, etc. In such an injection state, a problem that the connectivity between adjacent solid bodies cannot be obtained easily occurs. In the previous case, Japanese Patent Application Laid-Open No. 12-45259 was filed. According to this case, the majority of injection pipes are arranged in the site, and the site improvement materials are injected into the site through the majority of the injection pipes from the respective outlets. The above-mentioned improved material is pressed into each injection pipe by a plurality of tandem pumps in which most unit pumps in a set are operated by a driving source, and the spout is injected into the site at the outlet of -9- (3) (3) 591161. The above-mentioned known technique requires a long distance from the injection equipment to the injection hole for the injection tube, so it is necessary to use an injection solution with a low viscosity and a long coagulation time. However, once the injection solution with a long coagulation time starts to escape to the ground When the surface or the rough layer in the ground is unable to shorten the solidification time, it is necessary to stop the injection, and there is an inconvenience that the grout is solidified in the injection tube during the period. Most unit pumps equipped with pumps have different site conditions at the respective outlets, resulting in different optimal injection conditions. Therefore, all unit pumps are driven under the same conditions. It is impossible to perform the optimal injection at the discharge port. Therefore, the object of the present invention is to provide the advantages of a multi-point injection pump which can utilize the low-pressure infiltration injection grouting developed in the past for a wide area, as shown above, and correspondingly. The injection status of each grout injection pipe can arbitrarily manage the injection speed, injection pressure, injection suspension or reopening, coagulation time, etc. of each unit pump, and at the same time manage the actions of most unit pumps to grasp the management of the injection situation as a whole. The disadvantages of the known technology are to improve the multi-point site injection method and device. The other purpose of the present invention is to inject the solidification time when the rough injection of one injection, or when the solidification time during the injection is longer, and the grouting starts to escape. Short grouting is used to prevent this, and the practicability has promoted the practical development of multi-point injection of multiple continuous injection devices. Another object of the present invention is also to provide a layer of finely divided soil with less water permeability or different layers on the site. On the construction site, not only can the variable output volume be less than 1 liter to several liters per minute, it can be used simultaneously or Selectively reaches -10- (4) (4) 591161 into the most suitable injection, and can be vertical and horizontal three-dimensional injection in the site ', therefore, to improve the reliability of infiltration injection of finely divided soil layers, and due to the rapid The construction also shortened the injection period, and the site injection method and device that improved the shortcomings of the well-known technology mentioned above. It is another object of the present invention to provide a well-known technology that can use not only a solution-type injection material but also a suspension-type injection material, and thereby can select any injection corresponding to the site conditions of each injection site. There are many disadvantages to improve the site injection method and device. Means to solve the problem In order to achieve the above-mentioned object, according to the multi-point site injection method of the present invention, a plurality of injection pipes with a spit outlet are buried in a majority of injection sites on the site. The site injection method for multiple points of injection at the same time at the outlet is characterized by the use of multiple connected injection devices operated by separate drive sources and having multiple unit pumps controlled by a centralized management device, which are connected to most injection pipes through conduits The above-mentioned operation of most unit pumps injects the site improvement material from the majority of the outlets through the majority of injection sites in the site to perform multi-point injection. And, in order to achieve the above-mentioned object, the multi-point site injection device according to the present invention is characterized by having a site improved material storage tank, and being operated by independent driving sources in a set of equipment, and having a majority controlled by a centralized management device. The unit pumps are connected to the multiple connected injection devices of the storage tank, and most of the injection sites buried in the construction site are connected to each of the unit pumps through a conduit to connect the majority of the injection pipes with outlets, and the independent majority of the above-11 -(5) (5) 591161 Unit pumps each have a speed changer controlled by a centralized management device, and the above-mentioned conduit also has a flow pressure detector, so as to signal the flow and / or pressure data of the flow pressure detector It is sent to the centralized management device, and the site improvement materials in the storage tank are sent to each injection pipe at any injection speed, injection pressure, or injection volume by the operation of each unit pump. injection. The above-mentioned speed change transmissions are controlled in a batch by a centralized management device. Therefore, most unit pumps on the one hand have the function of independently performing the most suitable injection for each injection site, and on the other hand, they can constitute a group of injection devices that manage the injection of most injection sites as a whole.

In particular, the various pumps shown in Figures 3 to 7 are small, lightweight, and low-volume. They have less pulsation, simple structure, and are less prone to failure. Therefore, not only solution-type improvement materials, but also suspension type grouting are suitable Unit pump in the present invention. FIG. 2 is a schematic diagram of the piston pump 68. The piston pump 68 is composed of a plunger 12 and a piston rod 13 and a crank shaft 14 connected to the plunger 12 and a crank 16 that rotates together with the rotating shaft 15, such as As mentioned above, although the pressure is high and the output is large, the pulsation is large, large and heavy. FIG. 3 is a schematic diagram of a unit pump 3 according to the present invention using a plunger pump 11. As shown in FIG. In FIG. 3, the plunger 12 portion of the plunger pump 11 is reciprocally contained in the cylinder 18 filled with the gland packing 17 and the connecting rod 19 is connected to rotate with the rotating shaft 15 Of the crank 1 6. The cylinder tube 1 8 is connected to the suction hose 21 and the output hose 22 below the plunger 12. When the plunger pump 11 is in operation, first, the crank 16 is rotated together with the rotation shaft 15 to push the plunger 12 upward, that is, upward. At this time, the site improvement material of the site improvement material storage tank 2 shown in Fig. 1 is sucked through the suction hose 21 of Fig. 3, and the ball valve 23 is pushed open and a considerable amount of the plunger 12 is moved. Then, the crank 16 is rotated together with the rotation shaft 15 to push the plunger 12 in a direction, that is, downward. At this time, the attracted site improvement material is squeezed to close the ball valve 23 and simultaneously open the ball valve 24, and is sent out of the output hose 22. The conduit shown in FIG. 1 is pressure-fed to the injection pipe 8 and injected into the site 1. Injection points 6, 6 · · · 6. -14-(8) (8) 591161 FIG. 4 is a sectional view of a specific embodiment of the unit pump 3 of the present invention using a plunger pump 11. As in FIG. 3, the plunger 12 portion of the plunger pump 11 is reciprocated It is freely contained in the cylinder tube 18 filled with the gland packing 17 and the intermediate link 19 is connected to the crank 16 which rotates together with the rotation shaft 15. The cylinder tube 18 and the medium tube 20 are connected to the suction hose 21 and the output hose 22 below the plunger 12. In Fig. 4, 35 is a liquid holding tank on the suction hose side, which is covered by a cover 36. 37 is a liquid holding tank, and is covered with the cover body 38 similarly to the above. 39 is a pressed tablet of the covers 36 and 38. When the plunger pump 11 is operating, as in FIG. 3 described above, first, the crank 16 and the rotating shaft 15 are rotated together to push the plunger 12 in the upward direction, that is, upward. At this time, the site improvement material in the site improvement material storage tank 2 shown in FIG. 1 is sucked through the suction hose 21 of FIG. 3, and the ball valve 23 is pushed open and sucked in an amount equivalent to the movement amount of the plunger 12 and stored.于 保 液槽 35. Next, the crank 16 is rotated together with the rotation shaft 15 to press the plunger 12 in the opposite direction, that is, downward. At this time, the improved material in the suction fluid holding tank 35 was squeezed to close the ball valve 23 and push the ball valve 24 open. The pipes 20a and 20b were followed by the liquid holding tank 35 and sent out of the output hose 22. The conduit 10 of 1 is pressure-fed to the injection pipe 8 and injected into the injection site 6, 6 in the construction site 1. Fig. 5 is a sectional view of a diaphragm pump used in the present invention. The diaphragm pump has an eccentric installation. On the rotating shaft 49, the rocking plate 50 rotating with the rotating shaft 49 contacts one end of the rocking surface 50a of the rocking plate 50, the other end has a piston 51 with a diaphragm 51 and is actuated by the explosive force of the spring 52, and formed in the piston 53- 15- (9) (9) 591161 The side of the diaphragm 51 is formed by a space 56 including an introduction port 54 and a discharge port 55 of the site improvement material. The diaphragm pump configured as described above has a simple and small structure. When in operation, the rocking plate 50 is also rotated by the rotation of the rotating shaft 49. Since the rocking plate 50 is eccentrically mounted on the rotating shaft 49, the plate surface 50a thereof rotates obliquely. The piston 53 whose one end is in contact with the plate surface 50a rotates obliquely with the plate surface 50a, and swings left and right by the explosive force of the spring 52. At this time, the diaphragm 51 at the other end of the piston 53 also swells left and right. By its rocking force, the site improvement material is discharged from the introduction port 54 through the valve body 57 to the discharge port 55 through the valve body 58, and the introduction and discharge actions are repeated. . The valve bodies 57 and 58 are both check valves. Fig. 6 is an explanatory view of a squeeze pump used in the present invention. The squeeze pump has a pump tube 41 hidden along the inner surface of the cylinder 40. The pump chamber 44 inside the pump tube 41 is provided with a rotor 43 with pump rollers 42 and 42 at both ends which can rotate freely around the rotation shaft 45. The rotor 46 is pumped from the inlet 46 of the pump tube 41 to the site for improvement during operation. At the same time, the rotor 43 is caused to rotate by the rotation of the rotation shaft 45 from the state of FIG. 6 (a). At this time, as shown in FIG. 6 (b), the pump rollers 42, 42 at both ends of the rotor 43 squeeze the pump tube 41 as if they were pressing a toothpaste tube. As shown in FIGS. 6 (c) and 6 (d), The improved material is discharged from the discharge port 47 and discharged in the direction of the arrow. The pump tube 41, which has no improved material, is restored to its original state by the restoring force of the rubber itself. At this time, the attractive force reached was a vacuum of 740 mmHg and a maximum discharge pressure of 30 kgf / cm2. This kind of squeeze pump can feed mud or mud with high viscosity, high concentration and solids. 16- (10) (10) 591161 Figure 7 is an illustration of a snake-shaped pump used in the present invention. The pump is composed of a stator 59 with two internal screws and a rotor 60 that is free to rotate in contact with the inner surface of the stator 5 and has one thread with a half pitch, and the stator 59 and the rotor 60 are accommodated. The casing 61 is used to introduce the construction site modification material from one end 63 of the casing 61 between the stator 59 and the rotor 60. The inlet 62 is used to discharge the construction site improvement material from the other end 64 of the casing 61. The discharge port 65 is formed. That is, the pump of FIG. 7 is basically composed of a stator 59 φ fixed to the casing 61 and a serpentine rotor 60. The stator 59 has both ends cut into a semi-circular short groove with a special double female screw shape, and the single double male screw-shaped rotor 60 rotates at an eccentric distance e mm on its inner side and intends to rotate around the center of the stator 59. However, the wall of the stator 59 is formed by a short groove, so that it is zero. The position is moved up and down, and it becomes left and right motion at the 90 ° position of the stator 59. That is, when the rotor 60 is viewed from the front, if the two rotations are made to make a left turn, the ground improvement material advances through the gap 66 in the stator 59, and is guided through the duct 10 to an injection pipe (not shown). · The relationship between the stator 59 and the rotor 60 can effectively block the flow from the inlet to the outlet (the outlet 65) at each stage regardless of the rotation position, and can smoothly perform continuous operations. In this way, because the thread surface is completely engaged, the rotor 60 rotates as if the piston is slowly extruded in an infinite cylinder in one direction without pulsation, and the liquid volume in any section of the stator 59 is also equal, and the discharge amount corresponds to the rotation. The speed is often constant. That is, the advantages of the snake-shaped chestnut are: (1) continuous pressure feeding structure, quiet and no pulsation, (2) the corresponding number of revolutions can ensure the discharge of a predetermined capacity, (3) no valve body mechanism, because -17- ( 11) (11) 591161 This high-viscosity, high-concentration site improvement material is mixed with air bubbles and can also be transferred. (4) Because it can rotate forward, stop, and reverse in an instant, it can interlock with the automatic control device. (5) The replacement of the stator 59 and the rotor 60 is simple and the like. The unit pumps shown above usually consist of 5 to 100 units to form a multi-tank injection device. In a group, the unit pumps are arranged vertically, horizontally, or three-dimensionally. These unit pumps are each driven by a drive source such as a motor. In addition, each drive source is operated by a speed controller such as an inverter controlled by a centralized management device. Therefore, a plurality of continuous injection devices in a set of equipment are configured or integrated by supporting a plurality of independent unit pumps in order to avoid shaking, deformation or bending due to the action of their respective driving sources, such as a pedestal and a frame. Most needed. In the present invention, for example, when the unit chestnut 3 of 30cmx30cmx0.2cmm is arranged in four horizontal directions, four longitudinal directions, and three vertical directions, and is supported or supported by a support such as a frame, 48 unit pumps can be pumped. 3 is formed as a continuous injection device 5 with a minimum volume of 1.2m x 1.2mx 0.9m. Therefore, the continuous injection device of the present invention can be composed of 48 unit pumps, and the whole is assembled into a small and simple integrated injection device. Therefore, when using a plunger pump as a unit pump, a set of multi-injection devices has a small discharge pressure of 50 ~ 7 4 Mpa, a discharge volume of 50 ~ 1 1/7 liters / min, and a small size of 30 cmx 30 cm x 20 cm. In addition, the instructions of the central centralized management room urged the unit pump to discharge from the outlet 7 with an output of 1 to 7 liters / minute. The inverter was used to maintain the optimal injection speed and injection pressure for the given injection location. Most injection outlets (for example, 50 outlets) are injected in their entirety, and the overall output is managed in a batch of (1 ~ 7 -18- (12) (12) 591161) x 50 = 50 ~ 350 liters / minute, and Low particle discharge can be carried out, and the construction period can be shortened due to rapid construction.

At this time, the two injection pipes 8 and 8 are respectively set at separate injection sites 6 separated by a distance, and the liquid A and B are injected into the site 1 from the respective outlets 7 so that the two merge in the site 1 The response is also possible.

In FIG. 13, the flow rate and / or pressure data signal of the site improvement material detected by the flow pressure detector 27 of most of the catheters 10, 10, ··· 10 is sent to the centralized management device 26, and the data records and screen information are borrowed. It displays and monitors the injection status and performs injection management. Generally, because the alluvium is deposited horizontally, the water permeability coefficient in the horizontal direction is larger than the water permeability coefficient in the vertical direction. Therefore, in Fig. 13, the soil layer in the first stage has a slightly similar water permeability coefficient near any outlet, and the example is medium sand. In addition, the soil layer in section η also shows a slightly similar water permeability coefficient near any outlet. An example is fine sand. When injecting, firstly, the first stage is injected simultaneously using η injection pipes T 1 1 to T 1 η, and then from the second stage to the η stage. In Figure 13, after the injection is completed in the first injection area, move to the second injection area. The injection condition of the η branch in the i-th stage is shown in Fig. 1 丨. It is managed by injection into the monitoring disk, and the optimal injection for each injection tube is controlled. Also, the present invention is to drive each unit pump by an independent motor and other driving sources, and use a centralized management device to control the number of revolutions of the inverter 67 and the like, so that the integrated unit pump can be provided in a group as many as possible. Install the injection device in series to operate. In addition, the multi-tank injection device can arbitrarily manage the injection of each injection tube corresponding to the injection conditions of a plurality of injection tubes. That is, the multi-tank injection device is not only a device that manages the entire injection of a plurality of (n) injection tubes, but also a device that can optimally manage the injection of each injection tube. In the device of the present invention, at the time of injection, the output volume of each unit is 0 to 5 liters / minute. Multiple units of the injection device are connected to 0 to 5 liters. Χη = 0 to 5χη liters / minute. The number of unit pumps η = 30 Danger 5. η = 150 liters / minute. The effect of the invention is as described above. The multi-point site injection method of the present invention uses a multi-unit injection device with independent unit pumps, so that for sites with different levels of site conditions, it is possible to achieve the optimal injection for each layer simultaneously or selectively It can also implement vertical and horizontal three-dimensional injection in the site. In addition, the multi-point site injection device of the present invention is a device with multiple continuous injection devices, and is constructed as described above with most unit pumps. Therefore, any site improvement material can be simultaneously or in any amount and at any speed. Selective injection, for sites with different levels of site conditions, can implement the most appropriate injection for each layer and reduce the injection period. Moreover, the present invention can, for example, dispense at a low discharge speed of less than 1 liter to several liters / minute at various points, in particular, a variable discharge of 1 to 7 liters / minute. -25- (19) (19) 591161, to avoid damage to the site The ground is infiltrated and injected into the finely divided soil layer to improve the reliability of the infiltrated and injected into the finely divided soil layer. At the same time, it can also use the rapid construction of 50 ~ 350 liters per minute to shorten the construction period. In addition, by injecting the A liquid and the B liquid together, by changing the discharge amount of the A liquid and the B liquid during the injection, the cementing time can be arbitrarily set for each outlet, and the injection can be stopped only when it escapes. Pipe, and continue to maintain the injection operation of most other injection pipes. In addition, if all the injection pipes are set in the construction site, since the optional discharge port can be used for secondary injection at other discharge ports, it is possible to perform uniform low-pressure infiltration injection into all the construction sites from all the φ injection pipes according to the design.
