Field of the Invention The present invention relates to a level adjusting method for a road expansion joint, and more specifically, for example, when a road in a submerged tunnel connected with a seam gap is unevenly submerged. The present invention relates to a level adjustment method for an expansion joint that is attached across a joint seam.

た違った効果を発揮することも出来るものである。2. Description of the Related Art Conventionally, it is known that an expansion / contraction device developed for expansion / contraction joints of a superstructure of a bridge which is a statically fixed structure is diverted to a seam gap of a road and used as a joint for a road bridge. (For example, the microfilm of Jitsukai Sho 59-61306). This conventional expansion and contraction device that is diverted as a road bridge joint softens the impact when the vehicle passes through the gap portion provided for buffering, improves running performance, and protects the structure. Effectively exerting the effect. Further, different effects can be exhibited due to the difference in the type and scale of the target structure, the type of displacement appearing in the gap, and the difference in size.

従って、上部構造の間隙の幅の変位と回転変位に対応す

は、若干の量には対応出来るものの、大きな変位には対
応できるようになっていない。By the way, the expansion / contraction device developed for the expansion joint of the bridge superstructure is premised on that horizontal shear displacement and vertical shear displacement with respect to the width of the gap of the bridge superstructure hardly occur. Is designed and
Therefore, although it is possible to deal with the displacement of the gap width of the superstructure and the rotational displacement, it is possible to deal with a large amount of displacement with respect to the vertical shear displacement, although it can handle a small amount. It's not.

路面の走行性の犠牲が前提となり、走行を回復するに
は、再度設置し直す必要がある。Also in the case of bridges, although there are cases in which shear displacement in the vertical direction occurs, it is a displacement due to live load and is normally recovered to a state where there is no displacement. As a countermeasure for this case, a structure that can follow up and down shear displacement, and that has strength that can withstand the impact caused by shear displacement even after shear displacement has generally been taken. It is a method. However, when such a telescopic device is applied to a road joint in a submerged tunnel,
It is necessary to re-install it to recover the running condition on the premise that the road performance is sacrificed.

A step is generated at the road connection due to vertical displacement. With respect to the vertical displacement of the road connecting portion, the end portions of the respective constituents are reinforced so as to withstand the impact due to the step.

We have replaced it with a new one. In other words, repair work is required relatively early after construction.
For this reason, there has been a problem that a lot of labor and time are required, and a new expansion joint device is required for re-installation, and a large amount of cost is required.

It is installed according to the road surface gradient (5%) of a, and the upper surface of the remaining fixed portion 6b is the submerged box side road 10a with almost no subsidence.
It is installed according to the road gradient (0.4%) (see FIGS. 2 and 3).

The road surface gradient of the load supporting portion 3 gradually shifts from the road surface gradient of the vertical shaft side road 10a to the road surface gradient of the submerged box side road 10a (see FIGS. 4 and 5). And
If it is predicted that the vertical shaft side subsidence will proceed further, as shown in FIGS. 6 and 7, from the fixing member 14a of the road 10a on the side of the large amount of ground subsidence to the fixing portion 6 of the expansion joint main body 1.
a is removed, a level adjusting member 17 made of a steel plate having a predetermined thickness is interposed below the fixing portion 6a of the expansion joint body 1, and then the fixing portion 6a of the expansion joint body 1 is fastened to the road fixing member 14a again. By tightening and fixing via the member 15, the level of the load support portion 3 is adjusted according to the slope of the road 10a on the vertical shaft side.

ずかで済むものである。At this time, repair work is carried out by adjusting the thickness of the pavement material 18 on the vertical shaft side so that it is at the same height as the road surface of the vertical shaft 10a. When the subsidence of the shaft 10a on the vertical shaft side further progresses, the displacement of the unequal subsidence is dealt with by replacing the level adjustment member 17 with a thicker one. Since the level of the expansion joint body 1 is adjusted by the method as described above, the slope of the road surface is only the slope on the vertical shaft side, the slope on the submerged box side, and the slope between them. It does not damage the
There is little impact on the expansion joint body 1 and the damage to the expansion joint body 1 or the structure in the vicinity thereof is not unnecessarily hastened. Further, since the correction after the vertical displacement progresses is easy, the period of traffic regulation for that is short and the cost is low.

The road in the submerged tunnel is a road whose slope on the vertical shaft side is larger than that on the submerged box side, and when the expansion joint body is first installed, the road slope on the vertical shaft side and the surface of the expansion joint body. The roads on the vertical shaft side are subsided, the level of the expansion joint is adjusted, and then the road surface on the vertical shaft side is raised according to the level of the expansion joint body. Level adjustment method for road expansion joints.
