Description

[0002] During various types of construction, the inclination of buildings often needs to be measured and monitored. The inclination of the cofferdam also needs to be monitored during the cofferdam bottom sealing process, especially when the cofferdam is constructed above water during bridge foundation construction. The existing method for monitoring the inclination of steel cofferdams is mainly to have surveyors use a total station or a level to measure the elevation of the four corners of the cofferdam to obtain the height difference relative to the initial elevation, and to install an inclinometer tube on the inner wall of the steel cofferdam (the inclinometer tube is equipped with an inclinometer, such as a guide wheel fixed inclinometer) to measure the distance to the cofferdam. The inclination direction of the cofferdam can be obtained based on the positive or negative value of the height difference, and the ratio of the height difference to the distance to the cofferdam is the ratio of the height difference to the distance to the cofferdam.

[0034] Please see attached Figures 2 to 6 In one embodiment of the utility model, an inclinometer tube structure for a steel cofferdam comprises an inclinometer tube body 10 and a plurality of connection mechanisms 20 arranged at intervals along the length direction of the inclinometer tube body 10; wherein the inclinometer tube body 10 is in a square tube shape, and the inner wall of the inclinometer tube body 10 is provided with a longitudinal guide groove 110 for installing a guide wheel type fixed inclinometer 40; each of the connection mechanisms 20 is arranged on the outer wall of the inclinometer tube body 10, and the connection mechanism 20 is used to fix the inclinometer tube body 10 on the inner wall of a steel cofferdam (not shown).

[0035] It is worth noting that the inclinometer tube body 10 of the present application adopts a square tube form, rather than a round tube form as in the prior art. The inclinometer tube body 10 can be fixed to the inner wall of the steel cofferdam through a connecting mechanism 20, so that the inclinometer tube body 10 will not shake on the inner wall of the steel cofferdam. At the same time, since the square tube form is adopted, the rolling or misalignment of the round tube and the inner wall of the steel cofferdam can be avoided, thereby ensuring the measurement accuracy of the inclinometer. The present application has a simple structure and is stable to use.

[0036] As a preferred embodiment of the utility model, each of the connecting mechanisms 20 includes a first connecting member 210, a second connecting member 220, a third connecting member 230 and a fourth connecting member 240; the first connecting member 210 and the third connecting member 230 are respectively arranged on the outer walls of both sides of the inclinometer tube body 10, the second connecting member 220 is connected between the first connecting member 210 and the third connecting member 230, and is arranged on the outer wall of the inclinometer tube body 10 close to the steel cofferdam; the fourth connecting member 240 is arranged on the outer wall of the inclinometer tube body 10 away from the steel cofferdam; wherein,

Then, the fourth connecting member 240 is lowered and the overlapping end 242 of the fourth connecting member 240 is overlapped on the top of the clamping end 232 of the third connecting member 230 (at the same time in the overlapping space). Subsequently, the screw 250 can be tightened so that the screw 250 is pressed against the fourth connecting member 240 to hold the fourth connecting member 240 against the outer wall of the inclinometer tube body 10. In this way, the connecting mechanism 20 can firmly hold the inclinometer tube body 10, and then the second connecting member 220 can be welded to the inner wall of the steel cofferdam, so that the inclinometer tube body 10 can be fixed on the inner wall of the steel cofferdam without shaking, thereby ensuring the stability and accuracy of the measurement results of the guide wheel fixed inclinometer 40 in the inclinometer tube body 10.

In other embodiments, the number of the longitudinal guide grooves 110 can also be two, or a multiple of 2, to match the guide wheels on both sides of the guide wheel type fixed inclinometer 40.
