Adopting such scheme, outer support part and ground in use, are fixedly connected, it is possible to positioned in advance by casing, facilitate the installation of fixture simultaneously by keeper；Keeper hammers into ground, can also arrive the effect of vibrations and the pre-protection cylinder displacement reducing casing simultaneously.
As preferably, described keeper is that array is uniformly arranged.
Adopting such scheme, the keeper stress being uniformly arranged is more average, and casing better realizes stable effect.
As preferably, described keeper is provided with guide surface, and described guide surface is inwardly arranged from outer support part to ground inclination.
Adopting such scheme, guide surface facilitates fixture to insert in ground, more laborsaving time fixing, and guide surface has guiding function, corrects the direction of insertion of fixture.
As preferably, some described support members are in uniformly circumferentially arranging.
Adopt such scheme, circumferentially disposed can make being more uniformly stressed of support member, make casing entirety more stable, reduce vibrations.
In sum, this utility model has the advantages that
1, reducing the vibrations to casing, pre-protection cylinder is sunk, and plays the effect of mortar leakage prevention；
2, convenient disassembly, easy to maintenance；
3, convenient transport, has certain auxiliary to install the effect of casing.
