Embodiment Construction
[0023] 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.
[0024] see Figure 1 to Figure 6A construction method for a water well passing through an underground cave is carried out through, but not limited to, a limiting device for partially filling the underground cave, and the limiting device for partially filling the 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...

The invention relates to a construction method of a water well penetrating through an underground cave. The construction method comprises the following steps that A, an upper vertical hole section communicating with a to-be-filled area of the cave is dug from the ground; B, a limiting fence is installed in a guiding cave through the upper vertical hole section; C, filling materials are thrown into a space defined by the limiting fences through the upper vertical holes till the filling materials are connected with the top wall of the cave to form artificial surrounding rock; and D, a lower vertical hole section is dug below the upper vertical hole section, the water well is formed by the lower vertical hole section and the upper vertical hole section, and the lower vertical hole section penetrates through the artificial surrounding rock so that the artificial surrounding rock can form a leakage-proof blocking ring for separating the inner space of the water well and the cave. According to the construction method for the water well penetrating through the underground cave, the cave is filled in a local filling mode, and the construction method is used for solving the problems that when water well construction is conducted in a full filling mode, the construction period can be prolonged, and the filling materials and labor are wasted.
Description
technical field [0001] The invention belongs to the technical field of construction, in particular to a construction method for a water well passing through an underground cave. Background technique [0002] In the process of drilling a well on a foundation with an underground cave, the situation that the water well passes through the underground cave (such as a cave) may be encountered. In order to ensure that the water in the drilled well can emerge and not flow away from the cave, the cave needs to be filled. 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 filled to form artificial surrounding rock, and finally drill holes in the obtained artificial surrounding rock to form water wells. ...
