Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a track type liquid solidified soil slurry preparation device and its construction method. BACKGROUND

[0002] Filling of the trench is to ensure that the structure and soil are densely connected. Filling of the trench helps to ensure the lateral restraint of the basement, which is crucial for the structural embedded end. If the trench backfill is not dense, it will not meet this assumption, thereby affecting the stability and safety of the structure. Filling of the trench has a significant impact on the seismic and overturning resistance of high-rise buildings. By enhancing the integrity and stability of the structure, filling of the trench helps to reduce structural deformation under the action of earthquakes or wind loads. Currently, liquid solidified soil backfilling is used to meet the above requirements, which helps to prevent water and prevent underground structures from being submerged or deformed due to immersion, and also reduces the connected water head formed by the surface water infiltrating through the filling soil of the trench to the basement and the surface due to the non-compliance of the filling soil density and waterproof measures construction quality, thereby preventing the basement from floating.

[0003] The reasons for the difficulty in preparing liquid solidified soil slurry at present are as follows:

[0004] Most of the slurry preparation needs to be prepared in a processing plant, which cannot be prepared on site. On-site slurry preparation occupies a large area, and most project sites are small and do not have a slurry preparation site. Off-site slurry preparation consumes a large amount of water resources;

[0005] However, on-site liquid solidified soil slurry preparation has the following problems:

[0006] The construction project site is small, and the structure construction phase does not have slurry preparation conditions. Small slurry preparation equipment cannot meet the slurry demand and the filling demand of the trench. Off-site slurry preparation has difficulty in water supply, and cannot utilize the underground water during the excavation of the foundation pit, resulting in waste of water resources. SUMMARY

[0007] In order to overcome the defects of the prior art, a track type liquid solidified soil slurry preparation device and its construction method are provided to solve the problem of large site occupation of the existing on-site liquid solidified slurry preparation for foundation pit trench filling.

[0008] To achieve the above purpose, a track type liquid solidified soil slurry preparation device is provided, which comprises:

[0009] A mud pool template is formed by enclosing a pool;

[0010] Two rails are respectively arranged on the opposite sides of the slot opening of the pool;

[0011] A moving crossbeam is arranged above the groove, and two walking wheels are arranged at the two ends of the moving crossbeam respectively, and the track is supported by the walking wheels;

[0012] A mixer is arranged on the moving crossbeam, and the stirring blades of the mixer extend into the pool groove.

[0013] Further, a rack is arranged on the track, and the walking wheels are gears, which are rotatably arranged at the ends of the moving crossbeam, and the gears are engaged with the rack.

[0014] Further, the track is arranged along the length direction of the pool groove, and the rack is arranged along the length direction of the track.

[0015] Further, a driving motor is arranged on the moving crossbeam, and the driving motor is drivingly connected with the walking wheels.

[0016] Further, the ends of the moving crossbeam are respectively connected with two inclined beams, and driven wheels are arranged on the inclined beams, and the track is supported by the driven wheels.

[0017] Further, a length-adjustable connecting beam is arranged between the ends of the two tracks.

[0018] Further, the connecting beam comprises:

[0019] Two beam segments are coaxially arranged, and the ends of the two beam segments are respectively connected with the ends of the two tracks.

[0020] Two socket sleeves are movably arranged at the other ends of the two beam segments respectively.

[0021] Locking members for locking the beam segments are arranged on the socket sleeves.

[0022] The present application provides a construction method of a track type liquid solidified soil mud preparation device, which comprises the following steps:

[0023] A pool template is arranged in a foundation pit or a trench;

[0024] Two tracks are arranged on the opposite sides of the groove of the pool respectively;

[0025] A moving crossbeam is arranged above the groove, and two walking wheels are arranged at the two ends of the moving crossbeam respectively, and the track is supported by the walking wheels;

[0026] A mixer is arranged on the moving crossbeam, and the stirring blades of the mixer extend into the pool groove.

[0027] Soil and underground water of the foundation pit are added into the pool groove.

[0028] The mixer is turned on and the moving beam is moved along the length of the track, so that the soil and the groundwater are mixed evenly to form liquid solidified soil.

[0029] When the mud pit template is installed in the foundation pit, the liquid solidified soil is transported to the fertilizer tank for backfilling. When the mud pit template is installed in the fertilizer tank, the mud pit template is transferred to the next section of the fertilizer tank, so that the liquid solidified soil fills the current section.

[0030] The beneficial effects of this invention are as follows: the track-mounted liquid-solidified soil slurry preparation device can prepare slurry within the foundation pit, without occupying on-site construction space. This device allows for on-site soil extraction within the foundation pit, reducing soil transportation distances. The prepared slurry is pumped out using a slurry pump, further reducing the amount of soil transported off-site and protecting the ecological environment. This device can increase slurry production output to meet construction needs, and slurry preparation within the foundation pit reduces pollution to the site. Furthermore, this device can utilize groundwater from foundation pit dewatering as a slurry preparation water source, reducing groundwater discharge issues and minimizing water waste and cost.
