【考案の詳細な説明】
この考案は、シールド本体の前部と後部とを区
画する隔壁をそなえたシールド掘進機において、
切羽土砂がわに水、泥水を注入する装置に関する
ものである。[Detailed description of the invention] This invention is a shield excavator equipped with a partition wall that separates the front and rear parts of the shield body.
This relates to a device for injecting water or mud into the face earth and sand.
密閉形のシールド掘進機においては、切羽土砂
がわに水、泥水等を注入させると、掘削抵抗が減
少し、あるいは粘着している土砂を除去できる場
合がある。 In a closed-type shield excavator, injecting water, mud, etc. into the face of the earth and sand may reduce excavation resistance or remove stuck earth and sand.
つぎに、シールド本体の前部と後部とを区画す
る隔壁に取付けた従来の注水装置を第１図により
説明する。 Next, a conventional water injection device attached to a partition wall that partitions a front part and a rear part of a shield body will be explained with reference to FIG.
シールド本体の前部と後部とを区画する隔壁１
には、一端を切羽土砂がわＦに開口させた円管体
２ａが固定されており、円管体２ａの他端には開
閉弁３が連結されており、開閉弁３には給水源

れている。切羽土砂がわＦへ注水をする時には開
閉弁３を開き、注水を停止させる時には開閉弁３
を閉じる。 Partition wall 1 that separates the front and rear parts of the shield body
A cylindrical body 2a with one end opened to the face earth and sand wall F is fixed to the cylindrical body 2a, and an on-off valve 3 is connected to the other end of the cylindrical body 2a. (not shown) is connected to the cylindrical body 2b. Open the on-off valve 3 when injecting water into the face earth and sand wall F, and open the on-off valve 3 when stopping water injection.
Close.
この注入装置では、円管体２ａの一端は常に切
羽土砂がわＦに開口しているので、往々にして円
管体２ａ内に土砂が侵入して詰つてしまい、開閉
弁３を開いても注水が行われなくなる。 In this injection device, since one end of the cylindrical body 2a is always open to the face earth and sand side F, the cylindrical body 2a often gets clogged with earth and sand, and even if the on-off valve 3 is opened, Water injection will no longer be performed.
この考案は、土砂の侵入を容易に防止すること
ができる注水装置を提供することを目的とするも
のである。 The purpose of this invention is to provide a water injection device that can easily prevent the intrusion of earth and sand.
以下、この考案の一実施態様を第２図および第
３図により説明する。 An embodiment of this invention will be described below with reference to FIGS. 2 and 3.

いる。 The bifurcated tubular body 4 consists of a water inlet tubular body 4a and a water guide tubular body 4b that intersects with the water inlet tubular body 4a,
The water injection tubular body 4a is fixed to the partition wall 1. The water guide tubular body 4b is connected to an on-off valve 3, and a water guide pipe 4c connected to a water supply source (not shown) is connected to the on-off valve 3. A piston 6 connected to one end of a rod 5 is slidably housed in the water injection tubular body 4a, and a grip 7 is attached to the other end of the rod 5. A lid 8 is fixed to the end of the water injection tubular body 4a opposite to the earth and sand face, and the lid 8 is provided with a hole through which the rod 5 passes, and a seal 9 for preventing water leakage is attached.
注水を行わない時には、第２図に示すように、
にぎり７を介してロツド５を押しこみ、ピストン
６を注水管状体４ａの開口部に位置させる。これ
により注水管状体４ａおよび導水管状体４ｂ内へ
の土砂の侵入が防止される。 When not injecting water, as shown in Figure 2,
Push the rod 5 through the grip 7 to position the piston 6 at the opening of the water injection tubular body 4a. This prevents earth and sand from entering into the water injection tubular body 4a and the water guide tubular body 4b.
注入を行う時には、第３図に示すように、ロツ
ド５を引き戻して、ピストン６を注水管状体４ａ
につらなる導水管状体４ｂの開口部よりも後方に
ピストン６を位置させる。したがつて、開閉弁３
を開けば、水または泥水が、注水管状体４ａの開
口から切羽土砂がわＦに注入させられる。 When performing injection, as shown in FIG. 3, the rod 5 is pulled back and the piston 6 is inserted into the water injection tubular body 4a.
The piston 6 is positioned behind the opening of the water guide tubular body 4b. Therefore, the on-off valve 3
When opened, water or muddy water is injected into the face earth and sand wall F from the opening of the water injection tubular body 4a.
なお、ピストン６の摺動はシリンダ等を介して
行うようにしてもよい。 Note that the piston 6 may be slid through a cylinder or the like.
以上説明したこの考案によれば、注水時以外は
注水管状体の開口部を閉塞して土砂の侵入を防止
し、注水時には確実に注水を行うことができる。 According to the invention described above, the opening of the water inlet tubular body is closed except when water is being injected to prevent the intrusion of earth and sand, and water can be reliably injected when injecting water.
