Description
Technical Field
The invention relates to the technical field of civil engineering, in particular to an underground box type combined wall structure and an implementation method thereof.
Background
The utility model provides a cylinder does not have medium plate underground shaft structure, its structure wall is vertical cylinder and arranges, except the bottom plate, inside does not have other medium plates, has great inner space, and this kind of structure wide application is in the work well in deep buried tunnel, fields such as large-scale petrochemical storage tank. In a soft soil region, when the depth of an underground shaft is deep, a circular underground diaphragm wall 2 is generally adopted as a foundation pit supporting structure. In the prior art, the arrangement relation between the main structure wall of the basement and the foundation pit supporting underground continuous wall 2 mainly comprises three types of 'wall-separating type outer wall', 'composite wall' and 'overlapping wall':
(1) A fertilizer groove is formed between the main structure wall of the wall-separating type outer wall and the underground continuous wall 2, and waterproof materials can be paved on the water facing side of the main structure wall, so that the waterproof effect is good. However, the underground diaphragm wall 2 of the "off-wall type outer wall" is used only as a temporary support structure, and does not share the load in the permanent use stage, which is entirely borne by the main structure wall. For the cylindrical underground shaft structure without a middle plate, the main structure wall is in a cantilever state from above the bottom plate due to the missing middle floor, and the thickness of the wall is generally larger. If the underground diaphragm wall 2 is not used as a permanent structure, the construction cost of the main structure wall is greatly increased. Therefore, the construction cost of the "off-wall exterior wall" is also highest.
(2) The underground diaphragm wall 2 of the composite wall and the laminated wall can bear partial load in the permanent use stage, but because the main structure wall is closely attached to the underground diaphragm wall 2, the flexible waterproof material cannot be laid on the water facing side of the main structure wall (namely, cannot be waterproof), and the flexible waterproof material can only be laid on the back water side of the underground diaphragm wall 2 (namely, can only be waterproof in a reverse way) during construction, so that the effect of the waterproof material is greatly weakened. In addition, the main structural walls of the "composite wall" and the "superimposed wall" are not free to shrink during maintenance because the outer wall body side is restrained by the underground diaphragm wall 2, and structural wall cracks often occur. Therefore, the waterproof effect of the composite wall and the overlapped wall is generally inferior to that of the wall-separating type outer wall.
In combination with the above analysis, the "off-wall type outer wall" has reliable waterproof quality but high construction cost, while the "composite wall" and the "superimposed wall" have low construction cost but poor waterproof effect. Therefore, the invention provides an underground box type combined wall structure which is suitable for a cylindrical underground structure without a middle plate, can save the manufacturing cost by utilizing the underground wall as a permanent structure, can strengthen the waterproof effect of the structural wall, and simultaneously improves the horizontal earthquake resistance of the wall.
