Problems solved by technology

[0002] When a new building is constructed with earth-extruding piles, and there are multi-storey existing buildings with natural foundations around the site, the piles will push the foundation and form a large earth-extruding stress, which will damage the existing buildings function, form safety hazards, and cause civil disputes

Embodiment

[0020] Example, combined with figure 1 As shown in the figure, a method for relieving the stress of soil extrusion is to dig a soil extrusion stress relief ditch 1 with a width of 0.5m and a depth of 0.5m lower than the depth of the foundation bottom of the existing building. 2, the other side of the soil-squeezing stress relief ditch 1 is provided with a soil-squeezing pile 3.

[0021] A construction method for squeezing soil stress relief ditch, comprising the following steps:

[0022] Step 1: Excavating a soil-extruded stress relief ditch 1 with a depth of 0.5m and a width of 0.5m at a depth of 3 m from the existing building 2;

[0023] Step 2: Slope excavation is not required during excavation of soil compaction stress relief ditch 1;

[0024] Step 3: The excavated soil cannot be piled on the side of the stress relief ditch 1;

[0025] Step 4: During the construction of the soil-squeezing pile 3, ensure that the soil-squeezing stress relief ditch 1 is not filled.

Abstract

The invention relates to a soil squeezing stress eliminating method. A soil squeezing stress eliminating ditch with the width of 0.5m-1m and the depth of 0.5m lower than the depth of the bottom of a foundation of an existing building is dug, the distance between one side of the soil squeezing stress eliminating ditch and the existing building is 1.5m-3 m, and a soil squeezing pile is arranged on the other side of the soil squeezing stress eliminating ditch. In the piling process, due to the soil squeezing effect of the soil squeezing pile, large soil squeezing stress is generated on soil on the side of the soil squeezing pile, when the soil squeezing stress of upper-layer soil is transmitted to the ditch edge of the soil squeezing stress eliminating ditch, the soil squeezing stress cannotcross the soil squeezing stress eliminating ditch to generate the damage effect on the existing building, and therefore the upper-layer soil squeezing stress naturally disappears. Meanwhile, althoughsoil squeezing below 0.5m of the bottom of the foundation of the existing building generates certain deformation, the damage effect on the existing building cannot be generated, and therefore the damage effect on the multi-layer existing building adopting the natural foundation during soil squeezing pile construction is eliminated. The method is simple, practical and convenient to construct, and has the great popularization prospect.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for eliminating soil squeezing stress and the construction steps of soil squeezing stress eliminating ditch. Background technique [0002] When a new building is constructed with earth-extruding piles, and there are multi-storey existing buildings with natural foundations around the site, the piles will push the foundation and form a large earth-extruding stress, which will damage the existing buildings role, forming a safety hazard and causing civil disputes. [0003] Therefore, it is very important to invent a method that can eliminate the stress of soil extrusion and is easy to operate. Contents of the invention [0004] The object of the present invention is to provide a method for eliminating soil-extruding stress and the construction steps of the excavating soil-extruding stress ditch which is simple in construction and effectively eliminates the pushing effect of ne...
