A plurality of loading holes are pre-embedded in the reaction wall concrete structure, and the loading holes are arranged in a matrix and used for fixing test instrument equipment. The pre-buried loading hole installation positioning, verticality and loading hole end plate flatness index accuracy requirement is extremely high (designed to be millimeter level), so that the accurate installation of equipment and the accurate test data can be ensured.
The installation of the embedded part of the loading hole of the reaction wall adopts the on-site positioning installation of the loading hole monomer or the on-site integral assembly positioning installation of the loading hole factory assembly module for finish machining. The pitch between the measuring loading holes (loading hole modules) must be adjusted at the construction and installation site to meet the design requirements.
Usually, in the process of installing the loading holes, the distance between the loading holes is measured by adopting a common steel tape measure, or a four-hole or nine-hole distance sizing fixture. Because the loading hole has no solid circle, the steel tape has no fixed measuring point, and only the distance from the side edge of the loading hole pipe to the side edge can be measured, and the accuracy is poor. And the four-hole or nine-hole pitch sizing fixture is used for measuring the pitch of the loading holes, although the precision is high, the fixture is large in size, heavy and inconvenient to operate.

The end part of the steel tape is fixedly connected with the upper end surface of the first positioning plug through a bolt and a pressing plate.
The first positioning plug and the second positioning plug are both stepped cylinders, the diameter of the upper end of each stepped cylinder is larger than that of the lower end of each stepped cylinder, and the diameter of the lower end of each stepped cylinder is equal to the inner diameter of the loading hole.
The center of the circle of the upper end face of the second positioning plug is provided with a conical tip.
The working principle of the utility model is as follows:
and inserting the first positioning plug into the loading hole to be measured as a measurement starting end, inserting the second positioning plug into the other loading hole to be measured as a measurement terminal, pulling out a graduated scale of the steel tape to a conical tip of the circle center of the second positioning plug, wherein the value of the conical tip corresponding to the graduated scale is the hole distance of the two loading holes.
The steel tape is a 5m steel tape sold on the market. The positioning plug is 30mm in height, 80mm in diameter at the lower part, 20mm in height, 90mm in diameter at the upper part and 10mm in height.
The measuring tool for the hole pitch of the loading hole of the reaction wall is suitable for measuring the diameter of the loading hole by 80mm and the longitudinal and transverse spacing of the loading hole by 500mm (1000 mm). If the conditions of loading holes of different specifications of other models and the like are measured, the corresponding sizes of the steel tape are adjusted, but the steel tape device is not changed.
The utility model has the advantages that:
the utility model provides a measuring tool for the hole pitch of a loading hole of a counterforce wall, when the loading hole of the counterforce wall is installed, the measuring tool is simple, convenient and accurate in measuring the hole pitch of the loading hole and high in efficiency, overcomes the defects that a common steel tape is poor in measuring accuracy, a sizing fixture is large in measuring volume, heavy and inconvenient to operate, and the like, and provides a new measuring tool for high-accuracy installation construction of the loading hole of the counterforce wall.
