Foundation pit high-temperature bedrock crack water drainage and plugging structure and method

Abstract

The invention discloses a foundation pit high-temperature bedrock crack water drainage and plugging structure, and relates to the field of constructional engineering. The foundation pit high-temperature bedrock crack water drainage and plugging structure comprises a spring opening and a water collecting pit, the spring opening and the water collecting pit are connected through a drainage ditch, and two water collecting wells distributed side by side are arranged at the pit bottom of the water collecting pit. The invention further discloses a foundation pit high-temperature bedrock crack water drainage and plugging method. The following parts are included: A, a spring opening part; B, a drainage ditch part; C, a water collecting well part and D, plugging of a water outlet point; the blocking structure is formed through cooperation of the graded broken stone, the reinforced concrete, the non-woven fabric, the finished iron drum and the waterproof air bag, and the water outlet position can be rapidly and perfectly blocked. The spring openings, the drainage ditches and the water collecting pit are blocked through cooperation of the collected broken stone, the non-woven fabric and the reinforced concrete, then the water collecting well is formed through cooperation of the finished iron drum and the concrete, the water collecting well is blocked through the rubber water stop air bag, the reinforced concrete and the steel plate layer, and the blocking efficiency of the device is improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a water drainage and sealing structure and method for high-temperature bedrock cracks in foundation pits. Background technique [0002] The usual method of basement floor construction is 10 cm concrete cushion, laying waterproof membrane, tying the bottom plate reinforcement, and pouring concrete, which will easily cause groundwater leakage on the floor surface. Due to the excessive groundwater pressure, even if there is a waterproof layer, leakage will occur. [0003] In the prior art, grouting and foaming agent are routinely used. This water-stopping method is labor-intensive, time-consuming, and costly, and affects the subsequent construction and delivery of floor paint for the completed basement. Therefore, it is necessary to invent a structure and method for water drainage and plugging of high-temperature bedrock cracks in foundation pits to solve the above problems....
