Description

【０００１】
【発明の属する技術分野】
本発明は、地下構造物の築造工事において使用される、長距離推進を可能とする推進管から、混合した時化学変化によりゲル状の滑材となる二液性滑材を別々に供給する推進工法用ヒューム管に関する。
【０００２】
【従来技術】
滑材注入作業の良否は、推進速度や距離に係わるだけでなく、地盤沈下、偏土圧、蛇行等にまで影響を及ぼすものである。
従来は、地山と推進管の摩擦抵抗が大きくなると、ジャッキ推力により管端が破損し推進不能となる。
そこで、地山と推進管の摩擦抵抗を減らすために、図２３に示したように、推進管路ｄには、滑材注出機構Ｃを装備した掘削機Ａを推進方向最先頭に配置し、この滑材注出機構Ｃから滑材を推進管Ｂと土ｇとの隙間に注出して、地盤と推進管Ｂとの摩擦抵抗値を下げながら推進している。
また、接続管ごとに注入孔ｈの位置を回転して接合し、それぞれの注入孔hより滑材を注入し、３６０度全周に滑材を行き渡らせる工法（図２４参照）がある。
また、管全周に複数個の注入孔hを設け、複数個の注入孔hから滑材を供給して滑材を全周に滑材を行き渡らせる工法（図２５）があるが、いずれも一液性の滑材を供給するシステムであった。
【０００３】
【発明が解決しようとする課題】
しかし、前記従来の技術では、以下のような問題点がある。
(1)人が中に入って作業し難い小口径の推進管Ｂの場合にも長距離推進が求められるが、小口径の推進管の中に滑材ホースを取り付けて滑材を供給できないために滑材注出機能Ｃは先頭の掘削機にしか取り付けることができず、途中の管路に取付けることができない。従って、滑材を注出する注出機構は先頭の掘削機だけしか装備することができず、滑材の効果を長く持続させるためにゲル化する二液性の滑材が用いられるようになった。
しかし、滑材注出機構は管路の先頭の掘削機にただ１箇所設けられているため、推進管の側壁の土砂の状態によって、せっかく注出した滑材は地中に浸透して、滑材としての効果がなくなり、推進管に大きな推進力が働く。従って、該推進管は破裂し、途中で工事を中断することになるという問題点がある。
(2)また、地山への浸透を避けるためゲルタイムを早くすると、排出孔付近にしか滑材が行き渡らず、滑材の効果が十分発揮されないため、推進管に大きな推進力が働く。従って、該推進管は破裂し、途中で工事を中断することになるという問題点がある。
(3)上記図24の場合は、接合する管ごとに注入孔の配置位置が変わるため、施工時に管の回転作業が必要であり、各々離れて設けられたそれぞれの注入孔から滑材を注入する必要があり作業が面倒であるという問題点がある。
(4)上記図25の場合は、効果を高めるためには、管体により多数の注入孔を設けることとなるが、このことによって管体強度が弱くなるという問題点がある。また、離れて配置されたそれぞれの注入孔から滑材を注入する必要があり、作業が面倒である。
(5)一液性の滑材を供給した場合は、滑材の粘度が柔らかいため、供給された滑材は管外周部の地中に浸透してしまい滑材の効果がなくなる。そして、推進管に大きな推進力が働き管が破損したりして途中で工事を中断してしまうという問題点がある。また、供給された滑材は管外周部の地中に浸透してしまうため多くの滑材を必要と、その結果工事のコストが高くなっていた。
(6)二液性の滑材を予め混合し、1系統の配送管（管路）で配送しようとした場合は、配送中にゲル化してしまい配送不能となってしまうという問題点がある。
本発明は上記問題点を解決するために発明されたもので、二液性滑材を別々の２系統の管路で供給し、両液を排出口で排出させて地山へ滑材を有効に注入し、その地山と推進用ヒューム管の摩擦抵抗を減少させて推進力の増加を防止し、かつ推進速度を加速化可能とし、又地盤沈下、偏土圧、推進蛇行等の影響を極力少なくして設計通りの推進し得る推進工法用ヒューム管の提供を目的としている。

【０００８】
【作用】
二液性滑材を別々の２系統の管路で供給し、両液を排出口で排出させかつ反応させて地山へ有効に注入し得る。そして、その地山と推進用ヒューム管の摩擦抵抗を減少させて推進力の増加を防止し、かつ推進速度を加速化可能とし、又地盤沈下、偏土圧、推進蛇行等の影響を極力少なくして推進し得る。
【０００９】
また、円周方向等間隔に設けた4箇所の第１から第４の排出口５１,５２,５３,５４から第１液6と第２液61が別々に二系統の管路３から排出される。
【００１０】
更に、円周方向等間隔に設けた5箇所の排出口51,42,43,54,55から第１液6と第２液６1が別々に二系統の管路3から排出される。
【００１１】
また、排出口5を円周方向環状に形成した場合は、各排出孔を円周方向に複数箇所等間隔で一つ置きに配置したため、第１液6と第２液６1が別々に二系統の管路3から排出される。
【００１２】
更に、各排出孔A、A１、A２、A３、A４、A５、Ｂ、Ｂ1、Ｂ2、Ｂ34、Ｂ5の外面には、第１液６又は第２液６１が噴出する時のみ噴射力で開く逆止弁4ａを取り付け、各排出孔が二液性滑材で閉塞されるのを防止している。
【００１３】
なお、二液性滑材はゲルタイムが決っていて、予め混合して搬送することは出来ないので、排出孔からの排出後直ちに混合して反応させる。
【００１４】
また、二液性滑材供給のための注入口は２箇所であるから、二液性滑材は移動作業の必要がなく１ヵ所で簡単に注入できる。何れかの管路の１本が詰まる等の事故が発生しても他の管路には影響せずに、推進用ヒューム管全周から万遍なく排出される。
【００１５】
そして、二液性滑材が推進用ヒューム管全周に供給されると、地山と推進用ヒューム管の摩擦抵抗を減少させて推進力の増加を防止し、かつ推進速度を加速化できる。また、二液性滑材の有効な働きにより、地盤沈下、偏土圧、推進蛇行等の影響を極力少なくして設計通りの推進工法が得られる。
【００１６】
更に、カーブ推進への対応性も高めることが可能となり、二液性滑材注入時においては滑材の供給が確実になるから、止水性及び路面沈下に有効に機能できる。
【００１７】

【００３１】
この管路体4の第2実施例は、図7のように、排出口５を円周方向全周に環状に設けた推進工法用ヒューム管1にも実施される。
【００３２】
図8〜図９により管路体４の第３実施例を説明する。

【００３３】
管路体取付溝2には、各排出孔A、A１、A２、A３、A４、Ｂ、Ｂ1、Ｂ2、Ｂ3、Ｂ4、Ｂ5を円周方向に複数箇所等間隔で一つ置きに配置するため、一方端部に排出孔Alを推進方向と逆方向に設けた第１液6を排出する第1の管路31と、両端部に排出孔B 1と排出孔B2を推進方向と逆方向に設けた第２液６１を排出する第2の管路32と、両端部に排出孔A2と排出孔A3を推進方向と逆方向に設けた第１液６を排出する第3の管路33と、両端部に排出孔B3と排出孔B4を推進方向と逆方向に設けた第２液６１を排出する第4の管路34と、一方端部に排出孔A4を推進方向と逆方向に設けた第１液６を排出する第5の管路35とを順に並列させて連結した管路体4が配設されている。

【００３６】
【発明の効果】
本発明は上述の通り構成されているので、次に記載する効果を奏する。
(1)二液性滑材を各管路から別々に２系統で供給し、この二液性滑材を排出口に配置した管路の別々の注出孔より、排出口で同時に排出させて反応させる構成としているため、二液性滑材の第1液と第2液が排出され混合するとゲル状になる。従って、滑材は従来の一液性滑材のようには管外周部の地中には浸透し難い。
また、土質にもよるが、一液性滑材は一般に地山に吸収されやすい。しかし、排出口に設けた別々の噴射口より排出された二液性滑材の第1液と第2液は、排出口で化学反応してゲル状に硬化し、推進管の外周部に満遍なく行渡らせることができる。また、滑材の使用量は少なくできるため、工事のコストを安くできる。
【００３７】
(2)推進管路の最先端に取り付けられた滑材供給管より、一液性の滑材を供給しても、滑材の粘度がやわらかいため、供給された滑材は管外周部の地中に浸透してしまうため、最先端の滑材供給管から数本後方に、再度滑材供給管をセットしていた工法は不要となり、その分工事が安くできる。
【００３８】
(3)排出口を円周方向複数箇所に設けた場合は、二液性滑材の排出孔を同じ排出口に配置し、さらに、円周方向に複数個配置したため二液性滑材は排出時に混合し易くなると同時に、円周方向にまんべんなく充填ができるので、滑材の効果を最大限引き出すことができる。
【００３９】
(4)推進管路に礫層等の固い地盤が存在していた時は、最先端の滑材供給管から数本後方に、再度滑材供給管をセットすることによって、より効果的な長距離推進ができる．
【００４０】
(5)二液性滑材を供給するための注入口は2箇所であるから、滑材は移動作業の必要がなく１ヵ所で簡単に注入できる。また、何れかの管路の１本が目詰り等の事故が発生しても他の管路には影響しないので、二液性滑材は推進用ヒューム管全周から満遍なく排出される。
【００４１】
(6)２つの注出口から二液性滑材の第1液と第2液を搬送することにより、一箇所で滑材を注入でき、排出孔からは二液性滑材が全周に満遍なく供給できるため、推進工法での築造作業中に推進用ヒューム管外周面に均等に滑材を排出して供給できる。
【００４２】
(7) 二液性滑材が推進用ヒューム管全周に供給されると、地山と推進用ヒューム管の摩擦抵抗を減少させて推進力の増加を防止し、かつ推進速度を加速化できる。
【００４３】
(8) 二液性滑材の有効な働きにより、地盤沈下、偏土圧、推進蛇行等の影響を極力少なくして設計通りの推進工法が得られる。
【００４４】
(9) 二液性滑材注入時においては滑材の供給が確実になるから、止水性及び路面沈下に有効に機能できる。
【００４５】
(10)作業中に地山の土壌が排出口に侵入して該排出口を埋めるのを防止でき、二液性滑材を均等に排出できる。

BACKGROUND OF THE INVENTION
The present invention is a propulsion pipe that is used in construction work of underground structures and that separately supplies a two-component lubricant that becomes a gel-like lubricant when mixed by a propulsion pipe that enables long-distance propulsion. It relates to a fume pipe for construction methods.
[0002]
[Prior art]
The quality of the lubricant injection work not only affects the propulsion speed and distance, but also affects land subsidence, uneven earth pressure, and meandering.
Conventionally, when the frictional resistance between the natural ground and the propulsion pipe is increased, the jack end is damaged by the jack thrust and cannot be propelled.
Therefore, in order to reduce the frictional resistance between the natural ground and the propulsion pipe, as shown in FIG. 23, the excavator A equipped with the sliding material pouring mechanism C is arranged at the forefront of the propulsion direction in the propulsion pipe d. The lubricant is poured from the sliding material dispensing mechanism C into the gap between the propelling pipe B and the soil g, and propelled while lowering the frictional resistance value between the ground and the propelling pipe B.
Further, there is a construction method (see FIG. 24) in which the position of the injection hole h is rotated and joined for each connection pipe, the lubricant is injected from each injection hole h, and the lubricant is distributed all around 360 degrees.
In addition, there is a construction method (FIG. 25) in which a plurality of injection holes h are provided around the entire circumference of the pipe, and the lubricant is supplied from the plurality of injection holes h so that the lubricant is distributed all around the circumference. This was a system for supplying a one-component lubricant.
[0003]
[Problems to be solved by the invention]
However, the conventional technique has the following problems.
(1) Long-distance propulsion is also required for small-diameter propulsion pipes B that are difficult for humans to enter, but because it is not possible to supply the lubricant by installing a lubricant hose in the small-diameter propulsion pipe In addition, the sliding material extraction function C can be attached only to the head excavator, and cannot be attached to a pipeline on the way. Therefore, only the leading excavator can be equipped with the dispensing mechanism that dispenses the lubricant, and a two-component lubricant that gels is used to maintain the effect of the lubricant for a long time. It was.
However, since only one excavator is installed in the excavator at the head of the pipeline, the extracted lubricant penetrates into the ground depending on the state of the sand on the side wall of the propulsion pipe, and the The effect as a material is lost, and a large driving force works on the propulsion pipe. Accordingly, there is a problem that the propulsion pipe is ruptured and the construction is interrupted on the way.
(2) In addition, if the gel time is increased in order to avoid infiltration into the natural ground, the lubricant will spread only near the discharge hole, and the effect of the lubricant will not be fully exerted, so a large thrust acts on the propulsion pipe. Accordingly, there is a problem that the propulsion pipe is ruptured and the construction is interrupted on the way.
(3) In the case of FIG. 24 above, the position of the injection hole changes for each pipe to be joined, so it is necessary to rotate the pipe at the time of construction, and the lubricant is injected from the respective injection holes provided separately. There is a problem that the work is troublesome.
(4) In the case of FIG. 25 described above, in order to enhance the effect, a large number of injection holes are provided in the tubular body, which causes a problem that the tubular body strength is weakened. In addition, it is necessary to inject the lubricant from the respective injection holes arranged apart from each other, which is troublesome.
(5) When a one-component lubricant is supplied, the viscosity of the lubricant is soft, so that the supplied lubricant penetrates into the outer periphery of the tube and the effect of the lubricant is lost. In addition, there is a problem in that a large propulsive force is applied to the propulsion pipe and the pipe is damaged, so that the construction is interrupted on the way. Moreover, since the supplied lubricating material penetrate | infiltrated into the underground of a pipe outer peripheral part, many lubricating materials are required, As a result, the cost of construction was high.
(6) When a two-component lubricant is mixed in advance and an attempt is made to deliver it with a single delivery pipe (pipe), there is a problem that it becomes gelled during delivery and becomes undeliverable.
The present invention was invented to solve the above-mentioned problems. Two-component lubricant is supplied through two separate pipelines, and both fluids are discharged at the outlet to effectively use the lubricant to the natural ground. To reduce the frictional resistance of the ground and the propulsion fume pipe to prevent an increase in propulsive force and to accelerate the propulsion speed, and to prevent the effects of ground subsidence, uneven earth pressure, propulsion meandering, etc. The purpose is to provide a fume pipe for propulsion method that can be promoted as designed with as little as possible.

【The invention's effect】
Since this invention is comprised as mentioned above, there exists an effect described below.
(1) Two-component lubricant is supplied separately from each pipeline in two systems, and this two-component lubricant is discharged at the same time from the separate outlets of the pipeline located at the outlet. Since it is made into the structure made to react, when the 1st liquid and 2nd liquid of a two-component lubricant are discharged | emitted and mixed, it will become a gel form. Therefore, the lubricant is unlikely to penetrate into the outer periphery of the pipe like the conventional one-component lubricant.
In addition, although it depends on the soil, the one-component lubricant is generally easily absorbed by natural ground. However, the first and second liquids of the two-component lubricant discharged from separate injection ports provided at the discharge port are chemically reacted at the discharge port and hardened into a gel, and evenly around the outer periphery of the propulsion tube Can be crossed. Also, since the amount of lubricant used can be reduced, the construction cost can be reduced.
[00 37 ]
(2) Even if a one-component lubricant is supplied from the lubricant supply pipe installed at the forefront of the propulsion pipeline, the viscosity of the lubricant is soft. Since it penetrates into the inside, there is no need for a construction method in which the lubricant supply pipe is set again several times behind the state-of-the-art lubricant supply pipe.
[00 38 ]
(3) When there are multiple outlets in the circumferential direction, the two-component lubricant discharge holes are arranged at the same outlet, and moreover, the two-component lubricant is discharged in the circumferential direction. Sometimes it becomes easy to mix, and at the same time, it can be filled evenly in the circumferential direction, so that the effect of the lubricant can be maximized.
[00 39 ]
(4) When hard ground such as gravel layer exists in the propulsion pipe, it is more effective to set the lubricant supply pipe again several times behind the most advanced lubricant supply pipe. Distance propulsion is possible.
[00 40 ]
(5) Since there are two inlets for supplying the two-component lubricant, the lubricant can be easily injected at one place without the need for moving work. Also, even if an accident such as clogging occurs in any one of the pipes, the other pipes are not affected, so that the two-component lubricant is evenly discharged from the entire circumference of the propulsion fume pipe.
[00 41 ]
(6) By transporting the first and second liquids of the two-component lubricant from the two outlets, the lubricant can be injected at one location, and the two-component lubricant is evenly distributed all around the discharge hole. Since it can be supplied, the lubricant can be evenly discharged and supplied to the outer peripheral surface of the propulsion fume pipe during the construction work by the propulsion method.
[00 42 ]
(7) When the two-component lubricant is supplied to the entire circumference of the propulsion fume pipe, the frictional resistance between the ground and the propulsion fume pipe can be reduced to prevent an increase in the propulsive force and to accelerate the propulsion speed. .
[00 43 ]
(8) Due to the effective function of the two-part lubricant, the propulsion method as designed can be obtained with as little influence as possible, such as land subsidence, uneven earth pressure and propulsion meandering.
[00 44 ]
(9) Since the supply of the lubricant is ensured when the two-component lubricant is injected, it can function effectively for water stoppage and road surface settlement.
[00 45 ]
(10) It is possible to prevent soil in the natural ground from entering the discharge port and filling the discharge port during work, and the two-component lubricant can be discharged evenly.
