2. Compared with the existing supporting type, the utility model discloses required construction space is less, and the structure is no longer than the land used red line.
3. Compare with current diagonal casting bracing structure, utility model construction completion back, the foundation ditch does not have bearing structure member, and the earthwork can adopt the big formula of digging to clear away in the pit, and the bracing bottom earthwork need not clear away, has practiced thrift the earthwork volume of digging, and the bracing need not pass underground structure.
4. Compare with cement soil gravity type barricade, the utility model discloses the front portion adopts the batter pile, and the vertical direction has perpendicular anchor, and bracing bottom earthwork does not excavate, is favorable to the slope earthwork to be stable, erects the anchor and can applys prestressing force, and envelope lateral deformation can obtain effective control, and the foundation ditch excavation can reduce to the minimum to the influence of all ring edge borders.
5. Compare with traditional envelope, the utility model discloses will be greater than traditional envelope to the saving of time limit for a project and cost.
