New patent of high pressure jet grouting anchor cable

Firstly, consider whether the construction of high-pressure jet grouting pile meets the design requirements. If so, we can simply consider the construction of prestressed anchor cable. We can abandon the collapsed hole section first and carry out construction in other parts to check whether the collapsed hole is single or all. Adjust according to the situation. If there is no other good way, we have to fill in the collapsed hole section first, and then carry out the lower construction.
