Problems solved by technology

[0005] After the high-pressure and large-flow groundwater is exposed, the plugging construction is carried out. Because the dynamic nature of the groundwater is not conducive to the condensation of the grout, the grouting is difficult and the effect is poor.

Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] figure 1 It is a flow chart of the groundwater sealing method provided by the embodiment of the present invention. see figure 1 , the example includes:

[0017] 101. Obtain the geological structure of the water gushing section and the water outlet characteristics of the water gushing point;

[0018] Specifically, in this embodiment, the preset range of water gushing points is investigated in combination with geophysical prospecting tests. According to the detection results, purposeful drilling exploration is carried out around the concentrated water gushing parts of karst pipelines to find the location and scale of each main permeable zone, so as to provide guide follow-up work.

[0019] 102. According to the obtained geolog...

Abstract

The invention discloses a method for blocking underground water, and belongs to the field of building operations. The method comprises the steps that geologic structures of water burst sections and water discharging characteristics of water burst points are obtained; according to the obtained geologic structures of the water burst sections and the obtained water discharging characteristics of the water burst points, split-flow pressure relief vents are distributed in the water discharging points of which the single points are greater than a first preset value; according to the obtained geologic structures of the water burst sections and the obtained water discharging characteristics of the water burst points, grouting and water blocking holes are distributed in the water discharging points of which the single points are smaller than a second preset value. By the adoption of the technology of reasonable design, simple process and easy construction, selective water blocking penetrating through high-pressure and large-flow rich water areas in tunnels and underground constructions can be achieved, and normal construction of the tunnels and the underground constructions is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a groundwater sealing method. Background technique [0002] Groundwater is an important part of water resources. Due to the stable water quantity and good water quality, it is one of the important water sources for agricultural irrigation, industrial mining and cities. However, under certain conditions, changes in groundwater can also cause unfavorable natural phenomena such as swamps, salinization, landslides, and land subsidence. In the construction of tunnels and underground projects in deep-buried water-rich mountainous areas, when the groundwater is in a static or relatively static state before being exposed, the use of advanced grouting technology can effectively concrete stones and form a water-stop curtain with good leakage resistance together with surrounding rocks , but the construction period of advanced grouting is long, and it can only be used when the...
