Abstract
The utility model provides a hydraulic quick tamping foundation, which comprises a lower lying layer, a cushion layer and a top sealing layer; in the utility model, the setting of the cushion layer is that the cushion layer is the building residue soil or the gravel soil containing coarse particle materials, compared with the single lime soil adopted as the cushion layer, the bearing capacity of the underlying layer is improved, and the building wastes are fully utilized to fill the cushion layer, thereby shortening the construction time, reducing the construction cost, avoiding the phenomenon of dust raising during the construction, and meeting the environmental protection requirement; the setting of top seal, the top seal is consolidated the bed course, and inside the top seal prevented that water from permeating the ground, eliminated the inside collapsible volume of ground, improved the bearing capacity of ground.
Description
Technical Field
The utility model belongs to the technical field of tamp the ground, especially, relate to a hydraulic pressure tamps ground fast.
Background
Collapsible loess is a soil layer with thinner thickness, the collapsible grade of a collapsible loess foundation is generally a non-self-weight collapsible field, when the lower lying layer is collapsible loess, the foundation needs to be quickly tamped, and when multi-storey buildings, underground garages and the like meet the collapsible loess foundation in the prior art, because the requirement on the bearing capacity of the foundation is not high, a common treatment method is to change and fill an ash soil cushion layer, and the ash soil changing method has the defects of long construction period, high construction cost, easy generation of dust during construction and environmental pollution.
In the prior art, when a multi-storey building, an underground garage and the like meet a collapsible loess foundation, as the requirement on the bearing capacity of the foundation is not high, a common treatment method is to change and fill a lime soil cushion layer, and the lime soil replacement method has the defects of long construction period, high construction cost, easy dust raising during construction and environmental pollution.
Therefore, it is necessary to invent a hydraulic quick tamping foundation.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a ground is tamped fast to hydraulic pressure to solve prior art when encountering collapsible loess foundation when multi-storey building, underground garage etc. because the foundation bearing capacity requirement is not high, general processing method is to change and fill the lime soil bed course, and the shortcoming that the lime soil changed and filled the method is that the period of construction is long, engineering cost is very high, and the construction easily produces the raise dust moreover, causes environmental pollution's problem. A hydraulic quick tamping foundation comprises a lower lying layer, a cushion layer and a top sealing layer, wherein the cushion layer is arranged above the lower lying layer; the top sealing layer is arranged above the cushion layer.
Preferably, the thickness of the cushion layer is 0.5-2 m, the cushion layer is used for improving the bearing capacity of the underlying layer, and the cushion layer is building muck or gravel soil containing coarse particle materials.
Preferably, the thickness of the top sealing layer is 300-500 mm, the top sealing layer is used for reinforcing the cushion layer, and the top sealing layer is used for preventing water from permeating into the foundation.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the utility model discloses a setting of bed course, bed course are for containing coarse grain material's building dregs or rubble, compare and adopt single lime-soil as the bed course, improve the bearing capacity on bed layer, and make full use of building waste carries out the packing of bed course, shorten the engineering cost, reduce the phenomenon of raise dust when avoiding the construction, accord with the environmental protection requirement.
The utility model discloses a top seal's setting, top seal consolidate the bed course, and inside the top seal prevented water infiltration ground, eliminated the inside collapsible volume of ground, improved the bearing capacity of ground.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure:
1-a lower lying layer, 2-a cushion layer and 3-a top sealing layer.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
example (b):
as shown in figure 1
The utility model provides a hydraulic quick tamping foundation, which comprises a lower lying layer 1, a cushion layer 2 and a top sealing layer 3, wherein the cushion layer 2 is arranged above the lower lying layer 1; the top sealing layer 3 is disposed above the cushion layer 2.
In this embodiment, it is specific, the thickness of bed course 2 is 0.5 ~ 2m, and bed course 2 is used for improving the bearing capacity of bed course 1, bed course 2 is the building dregs or the hack soil that contains coarse grain material, compares and adopts single lime-soil as bed course 2, improves the bearing capacity of bed course 1, and make full use of building waste carries out the packing of bed course 2, shortens the engineering time, reduces engineering cost, the phenomenon of raise dust appears when avoiding the construction, accord with the environmental protection requirement.
In this embodiment, it is specific, the thickness of top seal 3 is 300 ~ 500mm, and top seal 3 is used for consolidating bed course 2, and inside this top seal 3 was used for preventing water infiltration ground, top seal 3 consolidated bed course 2, and inside top seal 3 prevented water infiltration ground, eliminated the inside collapsibility of ground, improved the bearing capacity of ground.
The utility model discloses, during the use, bed course 2 is the building dregs or the hack soil that contain coarse grain material, compare and adopt single lime-soil as bed course 2, improve the bearing capacity of bed course 1, and make full use of building waste carries out the packing of bed course 2, shorten the engineering time, reduce engineering cost, the phenomenon of raise dust appears when avoiding constructing, accord with the environmental protection requirement, top seal 3 consolidates bed course 2, inside top seal 3 prevents water infiltration ground, eliminate the inside wet sinking of ground, improve the bearing capacity of ground.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
