Double-fluid grouting bag type rapid hole sealing device

Abstract

The invention discloses a double-fluid grouting bag type rapid hole sealing device. The double-fluid grouting bag type rapid hole sealing device is characterized in that the double-fluid grouting bag type rapid hole sealing device mainly comprises a grouting pipe I, a grouting pipe II and a grouting bag; the grouting pipe I and the grouting pipe II are two independent pipelines, and a cement mortar solution and a water glass solution are delivered in the grouting pipe I and the grouting pipe II correspondingly; and the grouting bag is a cloth bag. The double-fluid grouting bag type rapid hole sealing device has the beneficial effects that by means of the characteristic that a mixture of cement mortar and water glass is easy to coagulate, a hole sealing material with a required size can be formed in the bag rapidly, and then an opening is blocked by the bag through water pressure; operation is easy and convenient, and the structure is simple; a hole in a basement base plate can be effectively sealed, and the situation that a large amount of silt and underground water gushes is prevented; the hole sealing effect is good, the structure is safe and reliable, and the applicability of the device is high; and the problem that cement mortar cannot be directly used for hole sealing under the condition that a large amount of water gushes can be solved rapidly.

Description

Technical field [0001] The invention relates to the technical field of rapid sealing, in particular to a double-liquid grouting bag type rapid sealing device. Background technique [0002] With the continuous development of urban underground space development and the continuous deepening of the basement depth, the difficulties encountered in the construction of underground space have also increased. In the event of a sudden rise in the groundwater level, or even higher than the ground surface, the basement floor is likely to be broken by water pressure due to the sudden increase in the buoyancy of the basement floor, and a large amount of sand and groundwater will gush out, and the broken holes on the floor cannot Cement mortar is used for direct and effective plugging. Even if the traditional construction method uses multiple drainage equipment to pump water at the same time, it can only achieve the relief effect and cannot quickly plug the hole to control the water inrush.

Problems solved by technology

[0003] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a double-liquid grouting bag-type rapid hole sealing device, which can not only effectively seal the holes in the basement floor, prevent a large amount of sediment and groundwater from gushing out, but also seal The fast setting speed of the plugging material can quickly solve the problem that cement mortar cannot be used to seal holes in the case of a large amount of water gushing. The process adopted by this device is simple, economical, environmentally friendly, safe and reliable
