Abstract
The utility model relates to an crowded native stress diffusion structure, the interval is provided with the pile foundation on the ground, has bored the crowded native stress diffusion hole that avoids the stake position in the within range of pile foundation, the aperture in crowded native stress diffusion hole is 400mm, and the degree of depth in crowded native stress diffusion hole corresponds the half of stake length, and crowded native stress diffusion hole intussuseption is full of the sand. In the pile is squeezed into the pile foundation, the stake extrudees the soil of ground to make the stake bury the ground smoothly, because the stake is squeezing into the ground process, the stake is constantly squeezing soil, leads to the soil of pile foundation below toward outer extrusion, the utility model discloses a bore the crowded soil stress diffusion hole that avoids the stake position at the within range of pile foundation, the soil of pile foundation below toward outer extrusion get into crowded soil stress diffusion downthehole, thereby unload the extrusion force, can not cause and produce the destruction to existing building, municipal pipe network, railway, bridge, also can avoid the foundation ditch excavation uninstallation back simultaneously, because the crowded soil stress that crowded soil stake produced makes the basement uplift, have popularization prospect.
Description
Technical Field
The utility model relates to a building field, in particular to crowded soil stress diffusion structure.
Background
The existing newly-built building generally adopts the construction of crowded soil stake, because there are multilayer or high-rise existing building, municipal pipe network, railway and bridge around the place, the stake produces the pushing effect to the soil body of ground in the construction, forms very big crowded soil stress, can produce the destruction effect to existing building, municipal pipe network, railway, bridge, forms the potential safety hazard, causes civil dispute, simultaneously, after the uninstallation of foundation ditch excavation, often because crowded soil stress that crowded soil stake produced makes the basement uplift, causes very big potential safety hazard and economic loss.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can not avoid the basement uplift of foundation ditch to the building production destruction on the ground, will squeeze a crowded soil stress diffusion structure of soil stress diffusion.
The purpose of the utility model is realized like this:
the utility model provides a crowded native stress diffusion structure, the interval is provided with the pile foundation on the ground, has bored crowded native stress diffusion hole that avoids the pile position in the scope of pile foundation, crowded native stress diffusion hole's aperture is 400mm, and the degree of depth of crowded native stress diffusion hole corresponds one-half of pile length, and crowded native stress diffusion hole intussuseption is full of sand.
In the pile is squeezed into the pile foundation, the stake extrudees the soil of ground to make the stake bury the ground smoothly, because the stake is squeezing into the ground process, the stake is constantly squeezing soil, leads to the soil of pile foundation below toward outer extrusion, the utility model discloses a bore the crowded soil stress diffusion hole that avoids the stake position at the within range of pile foundation, the soil of pile foundation below toward outer extrusion get into crowded soil stress diffusion downthehole, thereby unload the extrusion force, can not cause and produce the destruction to existing building, municipal pipe network, railway, bridge, also can avoid the foundation ditch excavation uninstallation back simultaneously, because the crowded soil stress that crowded soil stake produced makes the basement uplift, have fine popularization prospect.
The purpose of the utility model can also adopt the following technical measures to solve:
as a more specific aspect, every 20 mm2To 30mm2The four corners of the foundation are drilled with soil-squeezing stress diffusion holes.
As a more specific scheme, the sand filled in the soil-squeezing stress diffusion holes is fine sand.
The utility model has the advantages as follows:
the utility model discloses a pile is squeezed into in the pile foundation, and the pile extrudees the soil of ground to make the pile bury smoothly in the ground, because the pile is squeezing into the ground process, the pile constantly extrudees soil, leads to the soil of pile foundation below toward the extrusion outward, the utility model discloses a bore the crowded soil stress diffusion hole of avoiding the pile position in the within range of pile foundation, the soil of pile foundation below toward the extrusion outward get into crowded soil stress diffusion downthehole, thereby unload the extrusion force, can not cause and produce the destruction to existing building, municipal pipe network, railway, bridge, also can avoid the back of foundation ditch excavation uninstallation simultaneously, because crowded soil stress that crowded soil pile produced makes the basement uplift, have fine popularization prospect.
Drawings
Fig. 1 is a schematic view of the soil-squeezing stress diffusion structure of the present invention.
Fig. 2 is a schematic view of the soil-squeezing stress diffusion holes of the soil-squeezing stress diffusion structure of the present invention.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
in the embodiment, as shown in fig. 1 to 2, the soil-squeezing stress diffusion structure is characterized in that pile foundations are arranged on a foundation 1 at intervals, piles with the depth of 6m are adopted, and soil-squeezing stress diffusion holes 2 avoiding pile positions are drilled in the range of the pile foundations.
The aperture of the soil squeezing stress diffusion hole 2 is 400mm, the depth of the soil squeezing stress diffusion hole 2 corresponds to one half of the length of the pile (namely, the depth of the soil squeezing stress diffusion hole 2 is 3 m), sand 3 is filled in the soil squeezing stress diffusion hole 2, and the sand 3 is fine sand.
The area of the foundation 1 of this embodiment is 30mm2Soil-squeezing stress diffusion holes 2 are drilled at four corners of the foundation 1.
The working principle is as follows:
the method comprises the steps of firstly arranging pile foundations on a foundation 1 at intervals, adopting piles with the depth of 6m, drilling soil extrusion stress diffusion holes 2 avoiding pile positions in the range of the pile foundations, digging out soil in the soil extrusion stress diffusion holes 2 at four corners of the foundation 1, and filling fine sand in the soil extrusion stress diffusion holes 2.
At last, the pile is being squeezed into ground 1, because the pile is squeezed into ground 1 process, the pile constantly extrudees soil, results in the soil of pile foundation below to extrude toward the outside, the utility model discloses a bore crowded soil stress diffusion hole 2 that avoids the stake position at the within range of pile foundation, the soil of pile foundation below is toward extruding outside and gets into crowded soil stress diffusion hole 2 in, thereby unload the extrusion force, can not cause and produce the destruction to existing building, municipal pipe network, railway, bridge, also can avoid the foundation ditch excavation uninstallation back simultaneously, because crowded soil stress that crowded soil pile produced makes the basement uplift, has fine popularization prospect.
