Description
Technical Field
The invention relates to the field of measurement, in particular to a horizontal inclined hole inclinometer platform.
Background
In horizontal channel projects (such as urban subway communication channel projects, subway tunnel portal reinforcement projects, TBM (tunnel boring machine) solving projects and the like) constructed or repaired by adopting a freezing method, nearly horizontal freezing holes are often required to be constructed, and most of the holes range from horizontal to 50 degrees in elevation. Whether the spacing of the horizontal freezing holes meets the design requirement is the key of success or failure of the freezing method construction. Therefore, the exact position of the freezing hole in the soil body needs to be known, and a lamp light inclinometry method is often adopted in engineering to measure the deflection of the actual position and the design position of the freezing hole.
The horizontal frozen hole deflection refers to the situation that the frozen hole forming track deviates from the designed track, the vertical deflection angle is expressed by deflection distance and deflection angle, the data can be directly read by a theodolite, and the measurement calculation of the horizontal deflection angle is shown in the attached figure 1.
AC is the length of a horizontal freezing hole, A is the position of an opening of a freezing pipe, A ' is the position of the opposite side of the same circular ring pipe piece and is the same, and according to the similar triangle theory, C horizontal offset can be similarly projected onto the pipe piece by using a theodolite front mirror and a theodolite back mirror (reverse 180 degrees), namely A ' B ', and alpha=arcsin (A ' B/AB), wherein the distance values of A ' B and AB can be directly measured in a tunnel. Thus, the final well horizontal offset of the frozen well AC can be shown as ac·sinα. And (3) when the construction of a certain horizontal freezing hole is finished, performing theodolite lamp light inclinometry on the hole. When in inclinometry, firstly, a lamplight (generally a flashlight can be used) is sent to the bottom of a freezing hole by using an inclinometer rod; and then placing the theodolite on a special frame or platform, leveling and finding the lamplight, and measuring and calculating the offset distance and the offset angle of the freezing hole by using a positive mirror and a reverse mirror according to the method shown in the figure.
The inclinometer platform in the current engineering is generally a simple fixing frame, and both the support arm and the support plate are fixed and immovable, and the leveling of the instrument is related to the efficiency of the hole measurement due to the large pitch angle of the hole. In engineering, leveling of an instrument is achieved by means of padding cushion blocks on a support plate and adjusting supporting legs of the instrument, the leveling difficulty is high, the instrument is not fixed on the support plate and is unstable, measurement is easily affected by external factors, and if the cushion blocks cannot be leveled to a certain extent, the leveling range of the supporting legs of the instrument is limited, so that the leveling time is long, and the construction period is affected.
