Description

本発明は、スライム処理用サンドポンプに関し、特に現場築造杭や連続地下壁等を構築するために掘削した孔の底に貯留したスライムを有効に吸い込むスライム処理用サンドポンプに関する。   The present invention relates to a sand pump for slime treatment, and more particularly to a sand pump for slime treatment that effectively sucks slime stored in the bottom of a hole excavated to construct a site-built pile or a continuous underground wall.

従来のスライム処理用サンドポンプについて図３〜図５を参照して説明する。   A conventional slime processing sand pump will be described with reference to FIGS.

まず、スライム処理用サンドポンプを現場築造杭を構築するための堀削孔の内部で使用するときの状況の概要について、図３の模式図を参照して説明する。   First, the outline of the situation when the sand pump for slime treatment is used inside the excavation hole for constructing the site construction pile will be described with reference to the schematic diagram of FIG.

スライム処理用サンドポンプは、サンドポンプ１１とスライム処理機２１とを後述する数本のボルトによって連結して構成される。サンドポンプ１１の駆動回転軸１２は、下方に延長されて、その下端にスライム処理機２１のスクリュー２２が固定される。サンドポンプ１１の上部には、排水管１４が設けられ、また、電線１５（図４参照）が接続されている。   The slime processing sand pump is configured by connecting the sand pump 11 and the slime processing machine 21 with several bolts described later. The driving rotary shaft 12 of the sand pump 11 extends downward, and the screw 22 of the slime processing machine 21 is fixed to the lower end thereof. A drain pipe 14 is provided on the top of the sand pump 11 and an electric wire 15 (see FIG. 4) is connected thereto.

スライム処理用サンドポンプが挿入されている堀削孔３１の直径すなわち現場築造杭の直径はＤであり、堀削孔３１の底部付近にはスライム３２が貯留する。堀削孔３１の掘削に先立って建込まれたケーシング３３には、ベントナイト安定液等３４を堀削孔３１に注入するための供給管３５の一端部が挿入され、また、排水管１４の上端部とこれに連結される排出管３６の一端部が挿入される。排出管３６の他端部は、受ベッセル３７に挿入される。電線１５は、ケーシング３３を通過してキャップタイヤに接続され、電力がサンドポンプ１１の駆動源となるモータに給送される。なお、排水管１４の上部は、ワイヤ３８を介してクレーンから吊り下げられる。   The diameter of the excavation hole 31 into which the slime processing sand pump is inserted, that is, the diameter of the on-site construction pile is D, and the slime 32 is stored near the bottom of the excavation hole 31. One end of a supply pipe 35 for injecting bentonite stabilizing liquid 34 or the like into the excavation hole 31 is inserted into the casing 33 built prior to excavation of the excavation hole 31, and the upper end of the drain pipe 14. And one end of a discharge pipe 36 connected thereto. The other end of the discharge pipe 36 is inserted into the receiving vessel 37. The electric wire 15 passes through the casing 33 and is connected to the cap tire, and electric power is supplied to a motor that is a driving source of the sand pump 11. The upper part of the drain pipe 14 is suspended from the crane via the wire 38.

サンドポンプ１１が起動すると、スライム処理機２１のスクリュー２２が回転する。すると、堀削孔３１の底部付近に貯留するスライム３２は、撹拌されると共に浮上し、サンドポンプ１１に水と共に吸い込まれ、排水管１４と排出管３６を経て受ベッセル３７に排出される。   When the sand pump 11 is activated, the screw 22 of the slime processing machine 21 rotates. Then, the slime 32 stored in the vicinity of the bottom of the excavation hole 31 is agitated and floated, sucked into the sand pump 11 together with water, and discharged to the receiving vessel 37 through the drain pipe 14 and the discharge pipe 36.

スライム処理用サンドポンプを堀削孔３１から取り出した後に、ベントナイト安定液等３４を供給管３５から堀削孔３１の内部に注入し、以後現場築造杭を構築する作業を続行する。   After the sand pump for slime treatment is taken out from the excavation hole 31, the bentonite stabilizing liquid 34 is injected into the excavation hole 31 from the supply pipe 35, and the work for constructing the on-site built pile is continued thereafter.

次に、スライム処理用サンドポンプの構造と作用について図４と図５を参照して詳細に説明する。   Next, the structure and operation of the slime processing sand pump will be described in detail with reference to FIGS. 4 and 5. FIG.

サンドポンプ１１の下部には、サンドポンプ１１がスライム３２が混入した水を吸い込むことができる程度の距離を隔てて、上部取付用円板２４が数本のボルト１３によって取付けられている。   The upper mounting disk 24 is attached to the lower part of the sand pump 11 with several bolts 13 at a distance that allows the sand pump 11 to suck in water mixed with the slime 32.

スライム処理機２１は、円筒形状の上部水流方向制限板２３と、上部水流方向制限板２３の中央に配設され、かつ、サンドポンプ１１の駆動回転軸１２の下端に固定されたスクリュー２２と、上部水流方向制限板２３の上部に固定され、かつ、サンドポンプ１１の駆動回転軸１２の貫通孔２４Ａを中央に開けられた上部取付用円板２４と、スクリュー２２の下部に配設され、かつ、凹曲面２５Ａを有する中空円錐体形状の下部水流方向ガイド板２５と、上部取付用円板２４と下部水流方向ガイド板２５とを連結する数本の吊ボルト２６と、各吊ボルト２６の下部に固定された水流方向ガイド垂直板２７とから構成される。下部水流方向ガイド板２５の頂部と凹曲面２５Ａには、合計数箇所に水流吐出孔２５Ｂが開けられ、また、上部水流方向制限板２３の周囲には、数箇所に水流吸込孔２３Ａが開けられる。   The slime processing machine 21 includes a cylindrical upper water flow direction restriction plate 23, a screw 22 disposed at the center of the upper water flow direction restriction plate 23, and fixed to the lower end of the driving rotary shaft 12 of the sand pump 11, An upper mounting disk 24 fixed to the upper part of the upper water flow direction restricting plate 23 and having a through hole 24A of the driving rotary shaft 12 of the sand pump 11 formed in the center; and a lower part of the screw 22; A hollow cone-shaped lower water flow direction guide plate 25 having a concave curved surface 25A, several suspension bolts 26 connecting the upper mounting disk 24 and the lower water flow direction guide plate 25, and a lower portion of each suspension bolt 26 The water flow direction guide vertical plate 27 is fixed to the water flow direction guide. A total of several water discharge holes 25B are formed in the top of the lower water flow direction guide plate 25 and the concave curved surface 25A, and water flow suction holes 23A are formed in several places around the upper water flow direction restriction plate 23. .

サンドポンプ１１が起動すると、その回転軸１２を介してスライム処理機２１のスクリュー２２が回転する。すると、スクリュー２２は、その付近の水を矢印の方向に、すなわち、下部水流方向ガイド板２５の凹曲面２５Ａに沿って水平な放射方向と、下部水流方向ガイド板２５の数個の水流吐出孔２５Ｂを貫通して垂直下方向とに圧送する。この際、上部水流方向制限板２３には、その数個の水流吸込孔２３Ａから水が吸込まれる。したがって、堀削孔３１の底部付近に貯留するスライム３２は、撹拌されると共に浮上し、サンドポンプ１１に水と共に吸い込まれ、排水管１４と排出管３６を経て受ベッセル３７に排出される。   When the sand pump 11 is activated, the screw 22 of the slime processing machine 21 rotates through the rotating shaft 12. Then, the screw 22 makes the water in the vicinity thereof in the direction of the arrow, that is, the horizontal radial direction along the concave curved surface 25A of the lower water flow direction guide plate 25, and several water flow discharge holes of the lower water flow direction guide plate 25. It feeds vertically downward through 25B. At this time, water is sucked into the upper water flow direction restricting plate 23 from the several water flow suction holes 23A. Therefore, the slime 32 stored near the bottom of the excavation hole 31 is agitated and floated, sucked into the sand pump 11 together with water, and discharged to the receiving vessel 37 through the drain pipe 14 and the discharge pipe 36.

下部水流方向ガイド板２５は、中央円錐体形状であるが、単純な角錐体形状に設計変更することができる。また、上部水流方向制限板２３と上部取付用円板２４とは別体であるが、一体に構成するように設計変更することができる。更に、上部取付用円板２４の中央には、サンドポンプ１１の駆動回転軸１２の貫通孔２４Ａが開けられているが、一層大きい孔を開けて、上部取付用円板２４を孔開き円板に設計変更することができる。   The lower water flow direction guide plate 25 has a central cone shape, but the design can be changed to a simple pyramid shape. The upper water flow direction restricting plate 23 and the upper mounting disk 24 are separate bodies, but the design can be changed so as to be integrated. Further, a through hole 24A of the drive rotary shaft 12 of the sand pump 11 is formed in the center of the upper mounting disk 24. However, a larger hole is formed so that the upper mounting disk 24 is opened. The design can be changed.

以下に、本発明のスライム処理用サンドポンプの処理の増大方法及び装置の実施の形態について、詳細に説明する。   The embodiment of the method and apparatus for increasing the processing of the slime processing sand pump of the present invention will be described in detail below.

本発明の実施例１に係るスライム処理用サンドポンプの処理の増大方法及び装置について、図１を参照して説明する。本発明については、従来の技術と同様な点の説明を省略し、相違する点の説明を行う。   A method and apparatus for increasing the processing of the sand pump for slime processing according to the first embodiment of the present invention will be described with reference to FIG.
