Embodiment Construction
[0038] Reference figure 1 As well as figure 2 As well as Figure 4 , The first side wall of the first container 21 is opened on the side wall of the storage tank 29, from the alcohol solution sprayed from the nozzle 41 from the bottom wall of the first tolerance tank 21 and finally inflow into the storage waste tank 29 within 29It was collected by the storage waste tank 29. In this embodiment, the exit outlet with 29 connecting the storage tank 29 is opened on the bottom wall of the support board 2.In the cover, the staff separates the cover from the outlet, and then the waste liquid in the waste tank 29 flows out of the outlet to discharge the alcohol solution in the storage waste tank 29.
[0039] Reference Figure 4 There is an interval between the bottom wall of the bottom of the first capacity slot 21 and the board body 3. The staff can temporarily place the Mark pen in the interval between the bottom wall of the first capacity slot 21 and the board body 3, which is both conven...

The invention discloses an engineering project cost risk management device which comprises a supporting frame and a supporting plate, a first containing groove is formed in the supporting plate, a plate body is arranged on the first containing groove, a fixing groove is formed in the first containing groove, a cleaning assembly is arranged on the supporting plate and comprises a spray head and a rolling brush, the spray head is arranged in the fixing groove, and the rolling brush is arranged in the fixing groove. A water pump and a liquid storage tank are arranged in the supporting plate, the water pump is connected with the liquid storage tank and the spray head, a sliding groove is formed in the first containing groove, a sliding seat is arranged on the supporting plate, a first screw is rotationally arranged in the sliding groove, the sliding seat is in threaded connection with the first screw, a first driving source is arranged on the supporting plate, and the rolling brush is rotationally connected with the sliding seat. And a second driving source is arranged on the sliding seat, and when the board body is cleaned, handwriting on the board body is cleaned under the synergistic effect of the rolling brush and the alcohol solution, so that data is effectively prevented from remaining on the board body, and the privacy of the board body is improved.
Description
Technical field [0001] This application involves technical fields involving engineering costs, especially an engineering project cost risk management device. Background technique [0002] Project Costs (PC) refers to the construction cost that constitutes the estimated or actual expenditure of the engineering project at the construction period.The construction of engineering projects needs to be budget to the total cost of the construction before construction, and at every stage of the construction period, the total cost of the construction of the building must be recorded and verified.The actual cost and budget compare and check. [0003] At present, engineering costs generally use whiteboards to record the total construction cost and the cost of each stage of construction. The whiteboard includes the support frame and the plate body, and then the Mark pen is used to record on the plate body. [0004] In response to the above related technologies, the inventor found that there i...
