Embodiment 1

[0014] A method for repairing external force fractures of silty soft soil solidified base, which includes the following process steps:

[0015] 1) Digging a strip groove along the fracture position of the muddy soft soil solidified base, the width and depth of the strip groove are greater than the width and depth of the fracture position of the muddy soft soil solidified base;

[0016] 2) Use silt-solidified soil and curing agent to prepare the filled soft soil, the performance of the silt-solidified soil and the curing agent used to prepare the filled soft soil is consistent with the performance of the silt-solidified soil and the curing agent that constitute the silt soft soil solidified base;

[0017] 3) heat-treating the filled soft soil in step 2);

[0018] 4) Inject the heated filling soft soil in step 3) into the strip groove in step 1) through the grouting equipment, and vibrate the filling soft soil in the strip groove with a vibrator;

[0019] 5) Cover the strip gro...

Embodiment 2

[0022] As an improvement of the present invention, in the step 3), the heating temperature of the filling soft soil is 60 to 70°C, which can make the filling soft soil and the silty soft soil solidified base in the strip groove form a While maintaining a good bonding effect, avoid damage to its performance due to excessive heating during the heating process.

[0023] The remaining features and advantages of this embodiment are the same as those of Embodiment 1.

Abstract

The invention discloses a sullage soft soil solidifying base layer external force fracturing repairing method. According to the sullage soft soil solidifying base layer external force fracturing repairing method, in the repairing method, good connecting and fusion effects are formed between sullage soft soil used for filling and a sullage soft soil solidifying base layer by arranging a strip-shaped slot, so that the integrality of the repaired sullage soft soil solidifying base layer is higher, and the integral strength of the repaired sullage soft soil solidifying base layer is also be improved; and meanwhile, modulating is conducted on the sullage soft soil based on the volume of the strip-shaped slot, a lot of overflowing phenomena can be avoided in the repairing process of the sullage soft soil, and the sullage soft soil can be in full reaction and mesh with the sullage soft soil solidifying base layer better through heating processing on filler.

Description

technical field [0001] The invention relates to the field of geological engineering, in particular to a method for repairing external force fractures of silty soft soil solidified bases. Background technique [0002] With the prolongation of the service life, the solidified base of muddy soft soil often breaks due to the intervention of external force during actual use; the long-term existence of cracks on the solidified base of muddy soft soil not only affects its aesthetic effect, but also is easy to As a result, the structural strength of the base is affected; the existing treatment methods for the fracture of the solidified base of the above-mentioned silt soft soil are often directly repaired by grouting in the cracks. However, due to the inconsistent size and shape of the cracks, the actual repair During the process, it often occurs that the materials used for repairing and filling cannot be uniformly combined with the original silty soft soil solidified base, which le...
