両の偏荷重には十分対処できない。2. Description of the Related Art As a method of adjusting a manhole frame mounting foundation, a method of fixing a manhole frame to a rough adjusting material with a plurality of fixing bolts is known.
Since the manhole frame is supported in a dot shape, a stable installation state cannot be obtained, and an unbalanced load of the traveling vehicle on the manhole frame cannot be sufficiently dealt with.

A technique for laying fine adjustment materials made of fan-shaped resin spacers of various thicknesses on rough adjustment materials made of brick blocks, fan-shaped concrete blocks, etc. is disclosed.By this technology, an installation foundation close to a flat surface can be obtained. Therefore, the manhole frame can be installed relatively stably.

らに必要とする。However, the above-mentioned prior art requires a certain amount of skill and a lot of working time in order to optimally combine the fan-shaped resin spacers of various thicknesses in order to obtain a predetermined mounting base, and it is obtained thereby. Since the mounting base also includes steps, although it is minute, further application of resin material and filling work are required to obtain a truly planar mounting base.

を提供することにある。The problems to be solved by the present invention are as follows.
An object of the present invention is to provide a manhole frame mounting foundation adjusting method capable of constructing a planar mounting foundation precisely and with good workability according to a road gradient.

に際して、前記粗調整材及び微調整材の内の少なくとも
微調整材を、筒状基台上に配置した型枠内に硬化性材料
を打ち込むことにより形成することを特徴としている。A manhole frame installation foundation adjusting method according to the present invention is a rough adjusting member for installing a manhole frame at a predetermined position on a cylindrical base through a coarse adjusting member and a fine adjusting member. Further, at least the fine adjustment material among the fine adjustment materials is formed by driving a curable material into a mold arranged on a cylindrical base.

その場合、拡縮可能な弾性環状帯体からなる内型枠及び
外型枠を粗調整材の内周及び外周に各々圧接固定させて
もよい。In the above, for example, an annular rough adjusting material is formed on a cylindrical base, and an annular form made up of an inner mold and an outer mold is placed on the rough adjusting material and cured in the mold. The fine adjustment material may be formed by driving a conductive material.
In that case, an inner mold and an outer mold made of elastic annular strips that can be expanded and contracted may be fixed by pressure contact to the inner circumference and the outer circumference of the rough adjusting material.

きる。The manhole frame may be a metal frame in a handhole, a valve chamber, etc., as well as a normal circular manhole. Further, as the curable material, those made of epoxy-based or other resin mortar or resin concrete, which has a shorter curing time than ordinary concrete, can be suitably used.

【作用】筒状基台上において型枠を使用することによ
り、道路勾配に応じたマンホール枠据え付け基礎が筒状
基台上に平面状に構築され、その上に面状支持で据え付
けられたマンホール枠の上面は道路表面と整合する。[Operation] By using the formwork on the tubular base, the manhole frame installation foundation according to the road gradient is constructed in a planar manner on the tubular base, and the manhole is installed by planar support on it. The upper surface of the frame is aligned with the road surface.
【００１０】なお、据え付け基礎の基準となる道路勾配
については、走行車両からの衝撃荷重を可能な限り軽減
させる必要上から、通常は横断勾配よりも縦断勾配を優
先的に基準とすることが好ましい。With respect to the road gradient that serves as the basis for the installation foundation, it is usually preferable to preferentially refer to the longitudinal gradient rather than the transverse gradient because it is necessary to reduce the impact load from the traveling vehicle as much as possible. .

An inner mold 3 and an outer mold 4 each made of an elastic annular band that can be expanded and contracted are pressed and fixed to the inner circumference and the outer circumference, and an annular mold 5 is formed on the rough adjusting material 2. The inner mold 3 and the outer mold 4 can be expanded or contracted in a circumferential expansion or contraction direction by a known turnbuckle or a tightening device (not shown).

安定したものとなる。Then, after the primer 6 is applied to the upper surface of the rough adjusting material 2, the epoxy resin concrete is driven into the mold 5 and the fine adjusting material 7 is formed on the rough adjusting material 2. The installation foundation 9 according to the gradient of the road 8 is built directly on the tubular base 1. Since the mounting base 9 is composed of the ring-shaped stable rough adjusting material 2 and the rough adjusting material 2 integrally formed thereon in a planar shape, it becomes extremely stable.

After the primer 11 is applied to the lower surface, the manhole frame 10 is installed on the fine adjustment material 7 and the manhole frame 10 is filled with the paving material 12 according to a conventional method.
