Rockery is a kind of technology for producing stacked caves. In order to bear the weight of the upper layer, the foundation must be used in the construction of rockery. Must pay attention to more top, column, wall in the shape of the choice of rockery. The filler in the wall must have a precise global center of gravity and be hard enough. The joint between the inner wall and the stone pillar should be dense, and the mould and bracket can not be removed when the concrete and the bonding material are not strong enough.
The false cave consists of the following parts:
Cave Foundation and Foundation Stone: The rockery foundation stone is also called footstone. The artificial cave itself bears a great weight and has the function of touring. Therefore, its foundation must have enough bearing capacity, and the cave column and cave wall need to be the foundation. Artificial caves generally use wooden or stone piles as the foundation, while modern artificial caves mostly use reinforced concrete as the foundation. If the holes are piled up on the ground and in water, the foundation stones should start at the bottom of the pool, which will make the holes stronger.
Cave wall and pillar: Cave wall refers to the support of the whole cave. On the plane, it is a combination of points, lines and planes. The column is a point, the wall is a line and the hole is a plane. Cave walls are divided into two empty and one-sided supporting. For two empty cave walls, it is more complex in stacking. It is necessary to consider not only the load-bearing relationship of the structure, but also the requirements of view and lighting locations inside and outside the cave. Therefore, this kind of wall must pay attention to lightness and certain permeability when starting, and has higher requirements for stacking technology, and it is difficult to grasp. The treatment of single side wall retaining stone is simple, and thin feet should be paid attention to. Starting from the middle step by step, when the cantilever is different from the ordinary rocks, choose the hard stone without dark cracks, and fully consider the tension and pressure of the stone cover to ensure that the stone wall has enough reaction thrust of the cave wall. In morphology, the morphological characteristics of cave mother rocks should be considered.
Because of the limitation of span and length, the support method of pillar roof is usually used in the rockery cave. Columns refer to small, arch-shaped stone pillars piled on large stones, which are in the form of single, double and three pillars. The pillars are separated by a pile of stones, leaving one or two spaces as openings. The height of cave columns and walls should be considered in conjunction with the need to lift wool and tie the roof. In addition, the functional requirements of visitors entering caves should also be considered.
