本発明は、地下構造物用蓋の受枠を側塊上に設置するた
めの方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for installing a receiving frame of a cover for underground structures on a side mass.
地下構造物用蓋の受枠を設置する場合、受枠の上端面と
路面とに段差゛が生じないようにするために、受枠と側

常に何枚もの調整板を用意しておく必要がある。また、
調整板の厚み分だけの調整しかできないため、受枠の上
端面と路面とを正確に一致させることができない場合も
ある。When installing a receiving frame for the cover of an underground structure, in order to prevent a step from occurring between the upper end of the receiving frame and the road surface, adjusters made of iron plates, block pieces, etc. are installed at several locations between the receiving frame and the side blocks. The height and inclination of the receiving frame were adjusted by interposing an appropriate number of plates. However, when using this method,
It is necessary to always prepare several adjustment plates. Also,
Since adjustment can only be made by the thickness of the adjustment plate, it may not be possible to accurately align the upper end surface of the receiving frame with the road surface.
この高さ調節の問題を解消するものとして、実開昭５２
−７８９６６号公報では、第４図に示すマンホール蓋受
枠が提案されている。To solve this problem of height adjustment,
JP-A-78966 proposes a manhole cover frame shown in FIG. 4.

節する。この突出長さの調節により、傾斜した路面に対
しても、路面と一致した状態でマンホール蓋の受枠を設
置することができる。20 In the receiving frame, protrusions C are provided at several places on the seat of the receiving frame main body a, and a receiving seat d is provided at the lower end.
e is attached to this protrusion C. Then, the protrusion length of each adjustment pole (e) that protrudes below the seat is adjusted. By adjusting the protruding length, the manhole cover receiving frame can be installed in a state that is in line with the road surface even on an inclined road surface.
このようにして受枠を設置するとき側塊の内周形状が円
形であるのに対し、傾斜した状態で設置される受枠の内
周形状は楕円形になる。そのために、側塊と受枠との間
に生じる隙間を密閉する内型枠を現場合せによって作成
することは困難である。その結果、内型枠の間隙部から
モルタルが漏出しがちであった。加えて、通常のモルタ
ルにあっては、凝固時に収縮するため、空隙部を完全に
なくすことはできなかった。When the receiving frame is installed in this manner, the inner peripheral shape of the side block is circular, whereas the inner peripheral shape of the receiving frame installed in an inclined state is elliptical. Therefore, it is currently difficult to create an inner formwork that seals the gap between the side mass and the receiving frame. As a result, mortar tended to leak from the gaps between the inner forms. In addition, since ordinary mortar contracts during solidification, it has not been possible to completely eliminate voids.
したがって、車両等が通過する際にマンホール蓋に加わ

重として作用することになる。このため、長期間使用さ
れるときに側塊の上面が破壊され、受枠本体からのガタ
ッキが発生する欠点となる。Therefore, the load applied to the manhole cover when a vehicle or the like passes through it acts as a concentrated load on the upper surface of the side block via the adjustment bolt. For this reason, when used for a long period of time, the upper surface of the side block is destroyed, resulting in a drawback that looseness occurs from the receiving frame body.
このような問題のために、第４図に示した構造の受枠は
、はとんど実用されていないのが実情である。Because of these problems, the actual situation is that the receiving frame having the structure shown in FIG. 4 is hardly ever put into practical use.
そこで、本発明は、あらゆる傾斜の路面に対しても受枠
上端面を正確に一致させ、且つ受枠を側塊上に強固に設
置することにより、受枠本体からのガタッキが発生する
ことのない地下構造物用蓋受枠の設置方法を提供するこ
とを目的とする。Therefore, the present invention provides an underground structure in which the upper end surface of the receiving frame is accurately aligned with the road surface of any slope, and the receiving frame is firmly installed on the side mass, thereby preventing backlash from occurring from the receiving frame body. The purpose of this invention is to provide a method for installing a lid holder frame for objects.
本発明の地下構造物用蓋受枠の設置方法は、その目的を

下部との間に生じる空隙部分を弾性材料からなる環状内
型枠によって内側から密閉し、前記空隙部分に無収縮性
の急便性セメントを注入することを特徴とする。In order to achieve the objective, the method for installing a lid receiving frame for an underground structure of the present invention is such that level adjustment jigs are installed at multiple locations on the receiving frame of the underground structure lid installed on the side block. The level with the upper end surface is adjusted, and the gap created between the top surface of the side block and the lower part of the receiving frame is sealed from the inside with an annular inner form made of an elastic material, and a non-shrinkable expedient is applied to the gap. Characterized by injection of cement.

の設置後、早期に道路を開放することができる。As explained above, in the receiving frame installation method of the present invention, the level adjustment jig can be used to adjust the upper end surface of the receiving frame so that it is in alignment with any slope of the road surface. Moreover, since the expansion and contraction of the annular inner mold can be adjusted depending on the degree of air injection, the receiving frame can be installed quickly and leakage can be reliably prevented. Furthermore, since non-shrinkable quick release cement is injected into the void around the receiving frame, there is no shrinkage during hardening, and the load applied to the lid can be supported over the entire surface. Therefore, the upper surface of the side block does not break, and no looseness from the receiving frame body occurs. Furthermore, due to the quick delivery properties of cement, the road can be opened quickly after the installation of the cover frame for underground structures.
