Referring to fig. 1 to 5, the preferred embodiment of the present invention is shown.

The utility model provides a foundation ditch monitoring prism protection box, as shown in fig. 1, fig. 3, this foundation ditch monitoring prism protection box includes total powerstation A, box body 1, lid 2 and prism 3, total powerstation A and 3 mutual reflections of prism and received light, and measure the horizontal direction of foundation ditch and the displacement of vertical direction. Prism 3 locates inside box body 1, box body 1 is equipped with the hole 4 that sees through light of corresponding prism 3, and the positive reflection of corresponding prism 3 of box body 1 or the hole 4 of receiving light are regular shape or irregular shape, the shape structure of hole 4 includes square or circular at least. One side surface provided with the hole 4 is the front surface of the box body 1, and the box cover 2 is connected to the side edge of the front surface of the box body 1. The automatic box cover opening and closing device further comprises a starting mechanism for opening or closing the box cover 2, and the starting mechanism is a manual device or an automatic device.

Referring to fig. 5, in order to judge the safety of the supporting structure in the middle and later stages of the foundation pit construction, the horizontal or vertical displacement of the foundation pit needs to be monitored, the foundation pit can be planned according to a rectangular shape or other needed shapes, reference piers B for erecting a total station a are arranged at four internal corners of the foundation pit, the prisms 3 are installed in the box body 1, and the box body 1 for installing the prisms 3 is arranged outside the four surrounding fences at the top of the foundation pit or on the inner wall of a crown beam. Specifically, the box body 1 provided with the prism 3 is arranged at a certain distance around the outline C of the foundation pit, so that the total station A can perform light reflection and reception with the prism 3 without obstacles, according to the observation principle, the total station A utilizes the distance meter to emit laser to the prism 3, and the prism 3 reflects the received laser to the total station A, thereby measuring data.

In actual operation, reference piers B for erecting the total station A are arranged at four internal corners of a foundation pit (taking a rectangular foundation pit as an example), horizontal and vertical displacements of the top of the foundation pit are monitored, and when the automatic total station A monitors the horizontal and vertical displacements of the top of the foundation pit, the total station A is arranged at the reference piers B. When observing the monitoring points, the observation sight lines are dispersed and not overlapped due to the close distance, and the coordinates can be effectively measured. However, when the monitoring points with longer measurement distance are used, the observation sight lines of the monitoring points are almost overlapped due to the longer distance, and the phenomenon is more obvious when the distance is longer. Even when a remote monitoring point is observed, a plurality of monitoring points can be seen in the telescope A of the total station at the same time. The observation principle of the total station a is that the distance meter emits laser to the prism 3, and the prism 3 reflects the received laser to the total station a, thereby measuring data. However, in the case of a long distance and a short distance, the total station a emits laser once and can receive the laser reflected by the prisms 3 at the same time, which results in no recognition or an error in measurement and calculation. Thus, the cover 2, or prism 3, is selectively opened or closed as required for monitoring use by using the actuating mechanism. The problem of gathering of observation sight lines of remote monitoring points can be avoided. Specifically, when observing the monitoring point No. four, the box cover 2 of the monitoring point No. five and No. sixty can be closed through the starting mechanism, when observing the monitoring point No. five, the box cover 2 of the monitoring point No. four and No. sixty can be closed, when observing the monitoring point No. sixty, the box cover 2 of the monitoring point No. four and No. sixty can be closed, and thus the problem of observation line gathering can be effectively solved.
