Abstract

The invention relates to the technical field of pumping equipment. In order to solve the problem that the lift of the pumping equipment is too small, the pumping equipment for hole drilling pumping tests is provided. According to the technical scheme, the pumping equipment comprises a mounting bracket, a main rotating member rotating around the horizontal direction, a conveyor belt wrapping on themain rotating member and a main driving member for driving the main rotating member to rotate; the conveyor belt comprises a waterproof layer abutting against the main rotating member and a water absorbing layer located on the side, away from the main rotating member, of the waterproof layer, the mounting bracket is provided with an extruding assembly for extruding the conveyor belt, the extruding assembly comprises an auxiliary rotating member and a guiding member matched with the auxiliary rotating member to extrude the conveyor belt, and the mounting bracket is further provided with an auxiliary driving member for driving the auxiliary rotating member and the main rotating member to rotate in the same direction. Underground water is absorbed through the water absorbing layer of the conveyor belt and is transported to the extruding assembly, the water absorbing layer is extruded to extrude out the underground water absorbed in the water absorbing layer, the guiding member is used for flow guide and collection to bring out underground water in a deep drilled hole so as to conduct the hole drilling pumping tests.

Description

technical field [0001] The invention relates to the technical field of engineering survey, more specifically, it relates to a support device for an engineering survey level. Background technique [0002] Under the background of rapid social and economic development, land resources are becoming more and more scarce, which has led to an increasing intensity of underground space development. In recent years, the construction of transportation infrastructure has advanced rapidly, and more and more transportation infrastructure projects have been carried out in mountainous areas. Due to the advantages of "wide range of uses, little damage to the environment, and all-weather operation", tunnel engineering is favored by people and is gradually developing in the direction of "long, deep, and large". [0003] Practice has shown that complex geological conditions, difficult construction and poor construction environment are important factors affecting the construction progress of tun...
