Problems solved by technology
[0003] The method of full filling is easy to implement for small caves, but for large spaces or caves with unpredictable types, the construction method of overall filling is often unrealistic, and only the part through which underground piles pass is used for filling (hereinafter referred to as It is an ideal construction method to treat caves with the construction method of local filling), but due to the special conditions of underground caves, the local filling range is in an unpredictable and uncontrollable state. If the scope and volume of cave filling are too small, the The formed artificial surrounding rock cannot protect the underground piles or wells. If the cave filling area is too large, the construction period will be prolonged, and it will also cause waste of filling materials, labor and equipment. Therefore, how to realize the underground Partial filling construction of caves is a problem to be solved urgently in the construction field

Embodiment Construction
[0022] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] see Figure 1 to Figure 5, a method for partially filling an underground cave, which is carried out by, but not limited to, a limiting device for partially filling an underground cave. The limiting device for partially filling an underground cave includes a recycling frame and a limiting fence. The recycling rack comprises an upper circular frame 1, a lower circular frame 2 and several vertical air pipes 3 distributed along the circumferential direction of the upper circular fra...

The invention relates to an underground cave local filling method. The filling method comprises the following steps: A, an upper vertical hole section communicating with a to-be-filled area of a cave is dug from the ground; B, limiting fences are installed in a guiding cave through the upper vertical hole section; and C, a filler is thrown into the space defined by the limiting fences through upper vertical holes till the filler is connected with the top wall of the cave to form the artificial surrounding rock. The underground cave local filling method is provided and used for achieving local filling of the underground cave.
Description
technical field [0001] The invention belongs to the technical field of construction, in particular to a method for partially filling an underground cave. Background technique [0002] In the process of constructing buildings on the foundation with underground caves and carrying out underground pile construction or in the process of drilling water wells, the situation that underground piles pass through underground caves (such as karst caves) will be encountered. In order to ensure the construction quality of the underground piles and the water that is driven out can emerge without flowing away from the cave, it is necessary to fill the cave. The traditional method is to fill the underground cave as a whole. These filling materials are poured into the cave by pouring. The filling material is not subject to any restraint during the landing process, and is lowered to the cave in a loose manner by its own gravity. Subside and gradually accumulate until the cave is completely fi...
