Description

Technical Field

[0001] The utility model belongs to the technical field of construction surveying, and particularly relates to a project measurement device for earthwork excavation. Background Technique

[0002] Construction surveying refers to the surveying work such as control, lofting and completion acceptance for construction; earthwork excavation belongs to the category of construction surveying. Earthwork excavation is a key process in construction engineering, involving the work of loosening, breaking, excavating and transporting soil and rock. Before carrying out earthwork excavation, it is necessary to operate a project measurement device to measure the earthwork and carry out the earthwork excavation project more accurately.

[0003] After retrieval, a project measurement device for earthwork excavation is disclosed in the patent document with the patent publication number of CN213576593U, which includes a bottom plate. Both ends of the outer wall of the bottom of the bottom plate are hinged with support plates, and both ends of the outer wall of the bottom of the two support plates are hinged with fixing mechanisms. The fixing mechanism includes a telescopic rod, and a conical block is welded to the bottom of the telescopic rod. A fixing block is welded to the outer wall of one side of the conical block, and a fixing port is opened on the outer wall of the top of the fixing block. It can fold the support plates inwards for storage, then fold the telescopic rods outwards and fix them on the outer wall of the support plates through a limiting mechanism. After folding and storing, the device is convenient to carry and transport, making it more convenient for outdoor measurement. After the device is unfolded and fixed on the ground, the height of both ends of the mounting plate can be finely adjusted through an adjusting mechanism. By observing the bubble level, the mounting plate is in a horizontal position, making the measured data more accurate.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. For the above-mentioned project measurement device for earthwork excavation, both ends of the outer wall of the bottom of the bottom plate are hinged with support plates, and both ends of the outer wall of the bottom of the two support plates are hinged with fixing mechanisms. The fixing mechanism includes a telescopic rod, and a conical block is welded to the bottom of the telescopic rod. The support plates can be folded inwards for storage, and then the telescopic rods can be folded outwards and fixed on the outer wall of the support plates through a limiting mechanism. After folding and storing, the device is convenient to carry and transport. However, the above-mentioned project measurement device for earthwork excavation cannot hide and protect the project measurement instrument, resulting in poor protection effect of the project measurement instrument and even reducing the service life of the project measurement instrument;

[0006] 2. For the above-described earthwork excavation engineering quantity measurement device, two support plates are provided on the lower surface of the base plate, and two fixing mechanisms are provided on the lower surface of each support plate. Each fixing mechanism includes a telescopic rod, a cone block, and a locking bolt. By loosening the locking bolt and adjusting the length of the telescopic rod, the height of the above-described earthwork excavation engineering quantity measurement device can be adjusted. However, the large number of telescopic rods increases the workload of the staff.

[0007] Therefore, we provide an earthwork excavation engineering quantity measurement device to solve the problems described above. Utility Model Content
