従来複合注入方式の地盤改良工法に適用される装置として既に種々の構成のも のが提案されているが、例えば吐出の切換えを薬液の流速、圧力を利用して行う 方式のものは確実性に欠ける上に狭い管内に複雑な装置を設けなければならず必 然的に故障も多くなり、またボールを用いる方式のものは、送液を一度止め管内 にボールを入れなければならず手間がかかる上に再び吐出口を開くことができな いなどの問題点があった。また本出願人が先に提案した2重管ロッド方式による 複合注入装置(実公平3−3630号公報)によれば、上記従来装置の問題点を 一掃できるが、吐出口を切換えるために、駆動装置の作動をして内、外管のうち の内管を駆動しなければならず、装置面並びに操作面において、尚満足すべきも のでなかった。 Conventionally, various structures have been proposed as devices applied to the ground improvement method of the composite injection method, but for example, the method of switching the discharge by using the flow velocity and pressure of the chemical solution is more reliable. In addition, it is necessary to install a complicated device in a narrow pipe, which is inevitably chipped, and inevitably causes many failures.In the system using balls, it is necessary to stop the liquid supply once and put the balls in the pipe, which is troublesome. There was a problem that the discharge port could not be opened again. Further, according to the composite injection device by the double pipe rod method proposed by the present applicant (Japanese Utility Model Publication No. 3630/1990), the problems of the above-mentioned conventional device can be eliminated, but in order to switch the discharge port, driving The device had to be operated to drive the inner pipe of the inner and outer pipes, which was still unsatisfactory in terms of the equipment and operation.
【0003】 本考案はこのような従来の問題点を一掃することを目的としてなされたもので ある。The present invention has been made for the purpose of eliminating such conventional problems.

The convex joint portion 30 having the same structure and size as the side convex joint portion 30 is formed, and the joint portion 30 has communication passages 31a to 31d communicating with the tip liquid passages 5a to 5d formed in the plug body 3. Are formed.
【0036】 また中間部材1Bの基端側を凸ジョイント部30に於て、基端部材1Cの先端 側に接続するために、基端部材1Cの先端側に、中間部材1Bの凹ジョイント部 38と同一構造、同一寸法の凹ジョイント部38が形成され、凹ジョイント部3 8に設置されたジョイント金具29の4本の管状部34a〜34dの上部は、基 端部材1Cに形成された基端通液路20a〜20dの拡径部に挿着されている。 ジョイント金具29の抜脱防止のため止め輪37が適用されている。Further, in order to connect the base end side of the intermediate member 1B to the tip end side of the base end member 1C in the convex joint portion 30, the concave joint portion 38 of the intermediate member 1B is attached to the tip end side of the base end member 1C. A concave joint portion 38 having the same structure and size as the above is formed, and the upper portions of the four tubular portions 34a to 34d of the joint fitting 29 installed in the concave joint portion 38 are the base end formed in the base end member 1C. It is inserted and attached to the enlarged diameter portion of the liquid passages 20a to 20d. A retaining ring 37 is applied to prevent the joint fitting 29 from coming off.
【0037】 上記の構成により、中間部材1B、1B同士を接続する場合と同様に、中間部 材1Bと先端部材1A及び基端部材1Cをも、凹凸ジョイント部38、30を利 用して容易に接続することができる。With the above configuration, similarly to the case where the intermediate members 1B and 1B are connected to each other, the intermediate member 1B, the distal end member 1A and the proximal end member 1C can be easily formed by using the concave and convex joint parts 38 and 30. Can be connected to.
【0038】 凹凸ジョイント部38、30には、これを嵌合状態に拘束するために、図9に 示すように結合ピン39とピン穴40とからなる結合手段が備えられている。The concavo-convex joint portions 38, 30 are provided with a coupling means composed of a coupling pin 39 and a pin hole 40 as shown in FIG.
【0039】 ピン穴40は、凹ジョイント部38の外周壁38aと、凹ジョイント部38内 に嵌合している凸ジョイント部30との間に跨って横方向且つ直線状に形成され 、図9には180°の間隔で2個所に平行して形成した場合が示されている。こ のピン穴40にピン39を挿着することにより、凹凸ジョイント部38、30を 抜け止め且つ回止め下に拘束できる。The pin hole 40 is formed in a lateral and linear shape across the outer peripheral wall 38 a of the concave joint portion 38 and the convex joint portion 30 fitted in the concave joint portion 38. Shows a case where they are formed parallel to each other at 180 ° intervals. By inserting the pin 39 into the pin hole 40, the concavo-convex joint portions 38 and 30 can be prevented from coming off and restrained under the rotation stop.
【0040】 一方、ピン39を抜き出すことにより凹凸ジョイント部の嵌合を容易に解くこ とができる。On the other hand, by pulling out the pin 39, the fitting of the concavo-convex joint portion can be easily released.
【0041】 各段のジョイント部に於て、ピン穴40と連絡通路31a〜31dとの平面位 置関係は同一とせられている。これにより、凹凸ジョイント部38、30を嵌合 後、凹ジョイント側の穴部40aと凸ジョイント側の穴部40bとを位置合せし てピン穴40を形成すると、各段のジョイント部に於て、連絡通路31a〜31 dは自動的に上下に一致する。従って上記連絡通路31a〜31dにジョイント 金具29の管状部34a〜34dを介し連絡されている各段の通液路もまた自動 的に上下に一致する。而して先端部材1A、中間部材1B及び基端部材1Cを順 次接続して軸筒1を構成するに際し、連絡通路と通液路との位置合せ操作は特に 必要としない。In the joint portion of each step, the pin hole 40 and the communication passages 31a to 31d have the same planar positional relationship. As a result, after the concave-convex joint portions 38 and 30 are fitted, the concave joint-side hole portion 40a and the convex joint-side hole portion 40b are aligned to form the pin holes 40. , The communication passages 31a to 31d are automatically aligned vertically. Therefore, the liquid passages at the respective stages, which are connected to the communication passages 31a to 31d through the tubular portions 34a to 34d of the joint fitting 29, also automatically coincide with each other in the vertical direction. Thus, when the tip member 1A, the intermediate member 1B, and the base member 1C are sequentially connected to form the barrel 1, the operation of aligning the communication passage and the liquid passage is not particularly necessary.
【0042】 凹ジョイント側の穴部40aと凸ジョイント側の穴部40bとを自動的に位置 合せするために、各段のジョイント部に於て、凹ジョイント部38の外周壁38 aの下端面と、これに突き合せられる凸ジョイント部30側の外周部上端面との 間に、位置合せ用の凹凸部41a、41bが形成されている。而して凹凸部41 a、41bを嵌合すれば、穴部40a、40bが自動的に一致しピン穴40が形 成される。In order to automatically align the concave joint side hole 40a and the convex joint side hole 40b, the lower end surface of the outer peripheral wall 38a of the concave joint portion 38 at each step joint portion And the concave-convex portions 41a and 41b for alignment are formed between the upper end surface of the outer peripheral portion on the side of the convex joint portion 30 that is abutted against this. When the concavo-convex portions 41a and 41b are fitted with each other, the hole portions 40a and 40b are automatically aligned and the pin hole 40 is formed.
【0043】 本実施例によれば、凹凸ジョイント38、30の嵌合と、嵌合状態に於けるピ ン穴40へのピン39の挿着により、先端部材1A、中間部材1B、1B、…及 び基端部材1Cとを順次接続できるので接続操作が容易になると共に、ジョイン ト部の構造も簡素となる。さらに中間部材1Bの構成要素のうち、内管部分が一 本物のプラスチック製内管28から構成されているので、軽量となり、また材料 費が安いので、製造コストを低減できる。According to the present embodiment, the tip end member 1A, the intermediate members 1B, 1B, ...

Further, since the base end member 1C can be sequentially connected, the connection operation becomes easy and the structure of the joint portion becomes simple. Further, among the constituent elements of the intermediate member 1B, the inner pipe portion is composed of a single plastic inner pipe 28, and therefore the weight is light and the material cost is low, so that the manufacturing cost can be reduced.
【0044】 本実施例は、中間部材1Bの内管の部分が、一本物のプラスチック製内管から 構成される点、各部材1A、1B及び1Cの接続が凹凸ジョイント部の嵌合によ り行なわれている点及び凹凸ジョイント部の結合一体化が、ピンとピン穴との結 合手段の適用により行なわれる点を除き、図1に示す実施例のものと実質的に異 なる所がない。In this embodiment, the inner tube portion of the intermediate member 1B is made of a single plastic inner tube, and the connection of the members 1A, 1B and 1C is achieved by fitting the concave and convex joint portions. Except for the fact that it is performed and the connection and integration of the concavo-convex joint portion is performed by applying a connecting means of a pin and a pin hole, there is substantially no difference from the embodiment shown in FIG.
