Embodiment 1
[0033] see now figure 1 , figure 1 It is a schematic diagram of the waterproof structure of the porous wall of the vaulted basement according to the embodiment of the present invention. As shown, high pressure injector 20 is located within vault 12 . Described high-pressure pulse injector 20 comprises nozzle pipe 21, and nozzle pipe is connected to cylinder 22, and described cylinder 22 comprises piston 23, and described piston 23 is positioned at piston chamber 27, and described piston chamber 27 is connected by gas pipe 24,25, so The air pipe is connected to the high-pressure gas source 22 through a switch 26. The nozzle 21 is provided with a retractable nozzle 31 , and the nozzle 31 is configured to spray liquid in a circular discharge pattern with the nozzle 21 as the axis and toward the nozzle 21 .

The invention provides a waterproof treatment method for a vault basement porous wall. The waterproof treatment method is characterized by comprising the following steps that a, a plurality of holes are drilled in the porous wall with soil lower than the ground plane; b, steel pipes are inserted into the holes; c, a high-pressure pulse jetting device is started; d, the step b and the step c are repeated, liquid injection operation is conducted, and a complete resin coating is formed through the step b, the step c and the step d; e, resin is triggered to be cured; f, the step a, the step b, thestep c and the step e are repeated, and grouting operation is conducted; and g, all the drilled holes in the wall are blocked, and waterproof treatment of the vault basement porous wall is completed.The waterproof treatment method for the vault basement porous wall has the advantages that the inner layer and the outer layer of the wall, an organic silicon resin barrier, cement and a water glasscured object are simple in structure and convenient to construct, the waterproof effect of a totally-closed buffer structure is safe and reliable, the method is economical and reasonable, and the engineering cost is reduced.
Description
technical field [0001] The invention relates to a method for making the basement wall of porous concrete or masonry building impermeable, in particular to a method for waterproofing the porous wall of a vaulted basement. Background technique [0002] Concrete and masonry foundations, such as those found in basements of buildings or in subterranean vaults (such as utility power plants including aggregates in electrical distribution systems) are permeable and are constantly subject to water seepage unless in An impermeable barrier must be built on the inside or outside of the wall to stop water seepage. [0003] Seepage into basements or vaults is often caused by foundation settlement. The foundation rests on the soil and supports the weight of the entire superstructure. Some parts of the foundation may be weaker than others, and the result is an uneven weight distribution that often puts pressure on the wall causing it to crack, creating a wet entrance. Poor wall or founda...
