可能とする自走式の土質改良機械に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be used as a backfill material by improving excavated soil obtained by excavating a groove in pipe burying work for gas, water and sewage, etc. into a soil of good soil quality at the pipe construction site. A self-propelled soil improvement machine.
【０００２】[0002]
【従来の技術】ガス、上下水道等の管埋設工事は溝を掘
削し、その溝に管を敷設し、その後に溝を埋戻しするの
が一般的であり、その溝を掘削した掘削土が水分を多量
に含んでいたり、小石、岩片、コンクリート片等が混合
した劣悪な土質の場合には、その掘削土を溝の埋め戻し
材として使用できない。2. Description of the Related Art It is common practice to bury a pipe for burying gas, water and sewage, etc., lay a pipe in the trench, and then backfill the trench. If the soil contains a large amount of water or has poor soil quality such as pebbles, rock fragments, concrete fragments, etc., the excavated soil cannot be used as a backfill material for the trench.
【０００３】このように、掘削土が劣悪な土質の場合に
はトラック等で良好な土質の埋戻し材を運搬して溝を埋
戻し、その掘削土を残土として処分しているので、管理
設工事のコストが高くなるばかりか、施工時間が長くな
ってしまう。As described above, when the excavated soil has a poor soil quality, a backfill material having a good soil quality is transported by a truck or the like to backfill the trench and the excavated soil is disposed of as the remaining soil. Not only will the construction cost be high, but the construction time will be long.
【０００４】前述のように劣悪な土質の土砂を良好な土

２−３９８２７号公報に示すものが知られている。As a machine for improving the soil quality of the poor soil quality to the soil quality of the favorable soil quality as described above, for example, the actual construction method is 6
The one disclosed in Japanese Laid-Open Patent Publication No. 2-39827 is known.

のである。This soil improvement machine is equipped with a frame containing earth and sand hoppers, improvement material hoppers, mixers, earth and sand conveyor belt conveyors,
Install an improved material transport mechanism, etc., transport the sediment in the sediment hopper to the mixer by the sediment transport belt conveyor, and supply the improved material in the improved material hopper to the discharge section of the improved material transport mechanism to remove the soil and the improved material. It is agitated and mixed with a mixer to obtain good soil.

【発明が解決しようとする課題】前述の土質改良機械は
定置式であり、自走できないので管埋設工事現場に用い
る土質改良機械として好ましくない。The soil improvement machine described above is of a stationary type and cannot be self-propelled, so it is not preferable as a soil improvement machine used at a pipe burying construction site.
【０００７】なぜならば、管埋設工事は溝を順次連続し
て掘削しながら管を順次敷設して溝を埋戻しするので、
土質改良機械が定置式であると溝掘削場所と土質改良機
械との間の距離が順次長くなるから、掘削土を土質改良
機械の土砂ホッパまで運搬する作業が大変面倒となる。Because, in the pipe burying work, the pipes are sequentially laid and the trenches are backfilled while the trenches are continuously excavated.
If the soil improvement machine is a stationary type, the distance between the trench excavation site and the soil improvement machine will gradually increase, so that the work of transporting the excavated soil to the sediment hopper of the soil improvement machine becomes very troublesome.
【０００８】また、前述の土質改良機械は土砂ホッパ、
改良材ホッパ、混合機のフレームの長手方向に間隔を置
いて設置してあるので、それらの設置スペースが長くな
り、土質改良機械の全長が長いものとなる。The above-mentioned soil improvement machine is a soil hopper,
Since the improvement material hoppers and the mixer frames are installed at intervals in the longitudinal direction of the frame, the installation space for them is increased, and the soil improvement machine is increased in total length.
【０００９】また、土砂ホッパの下部と混合機の入口と

土砂ホッパ下部とフレームとの間に土砂搬送ベルトコン
ベヤが臨む上下方向の間隔があり、しかも土砂ホッパ下

から、その土砂ホッパ下部は土砂搬送ベルトコンベアの
幅と同一幅となるから土砂ホッパの容量を大きくすると
高さが高くなり、これらが相俟って土質改良機械の全高
が高いものとなる。Further, since the earth and sand conveyor belt conveyor is arranged over the lower part of the earth and sand hopper and the entrance of the mixer,
There is a vertical gap between the bottom of the sediment hopper and the frame that the conveyor belt conveys, and since the sediment is dropped from the bottom of the sediment hopper and supplied onto the conveyor belt conveyor, the bottom of the sediment hopper is Since the width is the same as the width, increasing the capacity of the earth and sand hopper will increase the height, and together these will increase the overall height of the soil improvement machine.
【００１０】一方、前述の管埋設工事は道路に沿って実
施されることが多く、土質改良機械の全長が長く、全高
が高い道路上を移動する際に道路と隣接する建物等の障
害物と接触することがあって小回り性が悪い。On the other hand, the above-mentioned pipe burial work is often carried out along the road, and the soil improvement machine has a long overall length, and when traveling on a road with a high overall height, it may cause obstacles such as buildings adjacent to the road. They may come into contact with each other and have a poor turning ability.

くない。Further, when the soil improvement machine has a high height, especially when the earth and sand hopper is high, the excavating and loading machine such as a hydraulic excavator which is used when the excavated soil is put into the earth and sand hopper becomes large, and is usually used in general pipe burying work. It is not preferable to use excavating soil in a small-sized hydraulic excavator because the excavated soil cannot be put into the sediment hopper.
【００１２】また、土質改良機械は長距離を移動する場

前述のように全長が長いと大型のトラックを必要とする
し、全高が高いとトラックの高さ制限を越えて特別な許
可を受けないと運搬できないことがある。Further, the soil improvement machine may be placed on a truck bed and transported when traveling a long distance,
As mentioned above, if the total length is long, a large truck is required, and if the total height is high, it may not be possible to carry it unless it exceeds the height limit of the truck and receives special permission.
【００１３】そこで、本発明は前述の課題を解消して管
埋設工事現場で使用するのに好適なる自走式の土質改良
機械を提供することを目的とする。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a self-propelled soil improvement machine suitable for use in a pipe burying construction site by solving the above-mentioned problems.

As shown in FIGS. 21 and 22, a cover body 150 is attached to the front wall 31a of the housing 31 of the disintegration mixer A. The cover body 150 has a box-like shape that opens downwards by an upper wall 150a, left and right vertical walls 150b, and a front wall 150c, and its lower opening edge is parallel to the upper surface of the belt 44 at a distance. This lower opening edge (left and right vertical walls 150b
A side cover 151 is attached to the lower edge), and the side cover 151 is a flexible plate such as a rubber plate and is in contact with both widthwise side portions of the upper surface of the belt 44. The upper surface of the belt 44 is substantially V-shaped.

As a result, rocks, large solids, etc., which have jumped out from the outlet 153 formed on the front wall 31a of the housing 31 collide with the chain 152 and fall onto the belt 44. Therefore, it is possible to prevent rocks, large soil, etc. from colliding with the belt 44 and damaging the belt 44.

As indicated by a phantom line in FIG. 1, the length is such that it protrudes downward from the upper surface of the belt 44, and when the belt 44 moves in contact with the upper surface of the belt 44, it makes circular contact. As a result, the lower edge portion of the cover body 150 and the belt 44 are airtight to some extent by the plurality of scattering prevention plates 154,
It is possible to prevent the improving material and the like blown out from the inside of the housing 31 of the disintegration mixer A from scattering around.

As a result, the modified earth and sand that have jumped out from the outlet 153 of the housing 31 are not covered by the rubber plate 15.
Since it collides with No. 8 and falls onto the upper surface of the belt 44, the improved earth and sand collides with the scattering prevention plate 154 and is not deformed. As a result, the lower part of the shatterproof plate 154 is attached to the belt 44.
Since it is not separated from the upper surface of the above, it is possible to reliably prevent the above-mentioned improved material from scattering.

For this reason, the earth and sand thrown into the housing 31 scatter toward the rear wall 31c by the disintegration mixer 33, but the earth and sand adhere to the adhesion prevention plate 170 and do not adhere to the inner surface of the rear wall 31c. Since the adhesion prevention plate 170 vibrates, the adhered earth and sand are peeled off and dropped, so that the adhered sediment does not adhere.
