Positioning equipment <br>after preparations are completed, the shift to the construction area flapper machine, the alignment plate alignment mark the sleeve. After the interposer is in place, perform leveling, centering, and adjust the verticality of the pile driver to ensure that the casing should be consistent with the pile position, the deviation should be within 30mm, and the verticality error of the drill hole is less than 1.5%. Commission the equipment before installation, and prepare for the construction of the drainage board after commissioning. <br>4.3.3.5 drainage board mounting <br>approach device after installation is completed, depending on the depth requirements of the card design, will be a good length of the cannula. The drain plate is pulled into the inside of the sleeve from the spigot of the sleeve and fixed on the pin at the bottom of the sleeve. At the same time, the drain plate is tightened and connected together by the friction force between the drain plate and the pin. With the end of the drainage plate drawn out, the casing is raised, and the drainage plate is left in the foundation by the pressure of the soil side.

Implement positioning <br>After the preparation is complete, the inserter shifts to the construction area so that the casing is aligned to the plate level marking. After the plate machine is in place, the leveling, alignment, adjusting the verticality of the pile machine, to ensure that the casing should be consistent with the pile level, the deviation should be within 30mm, drilling pertization error is less than 1.5%. Pre-set commissioning equipment, commissioning is ready to carry out drainage plate construction.<br>4.3.3.5 Installing the drainboard <br>After the installation and commissioning of the entry equipment is completed, the length of the intubation is set according to the depth requirements of the design insert. Draining plate from the intab of the casing into the casing, fixed on the bottom of the casing pin, while tightening the drainage plate, relying on the friction between the drainboard and the pin connected together, the upper lifting pin from the casing port and the end of the drainboard pulled out, the casing proposed, the drainboard on the soil side pressure left in the foundation.

Machine location<br>After the preparation, the board inserting machine shall be moved to the construction area to align the casing with the plate position mark. After the board inserting machine is in place, it shall be leveled and aligned, and the verticality of the pile machine shall be adjusted to ensure that the casing pipe is consistent with the pile position, the deviation shall be within 30mm, and the drilling verticality error shall be less than 1.5%. Pre commissioning equipment is set up, and drainage board construction is ready after commissioning.<br>4.3.3.5 installation of drain board<br>After the installation and commissioning of the mobilization equipment is completed, the length of the intubation tube shall be determined according to the depth requirements of the design plug plate. The drainage plate is pulled into the casing from the spigot of the casing, fixed on the pin at the bottom of the casing, and the drainage plate is tightened at the same time. It is connected by the friction between the drainage plate and the pin. When lifting up, the pin is pulled out from the casing mouth and the end of the drainage plate. The casing is raised, and the drainage plate is left in the foundation by the pressure of the soil side.<br>
