During operation, the lifting position of the cutterhead can directly be observed by the graduation on the scale, and control of the planning-milling depth can be very flexible and convenient.

The invention relates to a construction method for wall anti-alkali reaction, which belongs to the technical field of building construction. The construction method includes the following steps: take the moisture-proof material and paint it on the wall surface, and form a moisture-proof layer after natural drying to obtain the wall surface of the moisture-proof layer; take the acidic material and add it to warm water at 60°C, stir and mix evenly to obtain a weak acid solution; Take weak acid solution, evenly brush on the wall surface of the moisture-proof layer, and let it dry naturally for at least three days to obtain a dry wall surface of the moisture-proof layer; take waterproof putty, and apply the waterproof putty evenly on the wall surface of the dry moisture-proof layer, after drying 1. Grinding and removing dust to form a putty layer to obtain the wall surface of the putty layer; take the anti-alkali sealing primer, and evenly paint the anti-alkali sealing primer on the wall surface of the putty layer; Na 2 SiO 3 solution and CaCl 2 , after 1‑2 days of natural placement, take concrete to close the hole. The beneficial effect of the construction method is that it can fundamentally solve the phenomenon of anti-alkali on the wall.

The invention discloses a long button reset circuit of a microprocessor for equipment and its compound function method. A charging and discharging circuit is added between the power key pin and the reset pin of the microprocessor, and the charging time is much longer than the discharging time. Features, through the judgment of the microprocessor, the multiple function multiplexing of the long button reset button is realized, which overcomes the problem that the traditional reset circuit set separately is prone to misoperation, and the reduced single reset button not only makes the device beautiful, but also facilitates the waterproofing of the device deal with. The present invention introduces the charging and discharging circuit into the solution, increases the reliability of reset, and avoids the influence of misoperation on the system. The present invention introduces the inverter chip into the scheme, which not only has high integration, but also adds the reminder function of loudspeaker and indicator light.
