1, centralized point-like arrangement, generally arranged under the column;
Advantages: can make full use of the vertical force transmitted from the superstructure to balance off part of the water buoyancy; due to the centralized arrangement of mining anchors, it is also more convenient for the construction of external waterproofing under the basement floor; for the case of insufficient bearing capacity of the individual mining anchors, there is strong resistance due to the sharing of a larger number of mining anchors.
Disadvantages: the requirement of anchoring in hard rock, not applicable to soft rock and soil, the damage is often the damage of the anchored rock; due to the local mining anchors are denser, mining anchor construction is not convenient; basement floor beams and plates with larger reinforcement.
2,Centralized linear arrangement, generally arranged under the basement floor beam;
Advantages: due to the relatively centralized arrangement of mining anchors, it is also more convenient for the construction of external waterproofing under the basement floor;
For the case of insufficient bearing capacity of individual mining anchors, due to the sharing of a larger number of mining anchors, there is a stronger resistance.
Disadvantages: can not make full use of the vertical force transmitted from the superstructure to balance out part of the water buoyancy, requires anchoring in the harder rock, not applicable to soft rock and soil; basement floor plate plate reinforcement.
3, face uniform arrangement, uniform arrangement under the basement slab;
Advantages: applicable to all soils and rocks; basement slab beams and plates with smaller reinforcement.
Disadvantages: can not make full use of the vertical force transmitted from the superstructure to balance out part of the water buoyancy; for the individual mining anchor bearing capacity is insufficient, due to the share of the mining anchor is less, this case of resistance is poor; due to the relatively decentralized arrangement of mining anchors, for the basement floor under the external waterproofing construction is more troublesome.
4,Centralized point arrangement is recommended for hard rock; centralized line arrangement is recommended for hard rock and harder rock; face uniform arrangement is recommended for all cases.
