Abstract
The utility model discloses an underground structure with an internal counterweight, which is at least made of an underground structure bottom plate and an underground structure side wall arranged on the underground structure bottom plate; the underground structure bottom plate is provided with a counterweight filling material layer, and the counterweight filling material layer is provided with an underground structure bottom plate surface layer. The utility model discloses the higher regional underground structures anti problem of floating of groundwater level of having solved more economical has characteristics such as simple structure, construction convenience, construction quality easily control, efficiency of construction is high, the cost is low.
Description
Technical Field
The utility model relates to an underground structure (basement), specifically be an interior counter weight underground structure.
Background
Underground structures such as underground pools, underground receiving tanks and the like and basements exist in large quantities in industrial buildings and civil buildings, and the anti-floating problem of the underground structures and the basements in regions with high underground water level is a problem to be solved. The prior art generally solves the anti-floating problem by the following methods: 1. increasing the thickness of the bottom plate and the side wall of the underground structure; 2. carrying out cantilever on a bottom plate of the underground structure, and carrying out soil loading on the base plate for increasing a balance weight; 3. arranging an anti-pulling pile or an anti-pulling anchor rod; 4. and adding a counterweight outside the underground structure. The prior art suffers from the following different disadvantages: the prior art 1 has high manufacturing cost; the prior art 2 is suitable for underground structures with small areas, and the method 2 can only solve the problem of integral anti-floating and can not solve the problem of local anti-floating when the underground structures have large areas and no upright columns are arranged in the middle of a bottom plate; in the prior art 3, the construction cost of the uplift pile is high, the construction cost of the uplift anchor rod is high, and the construction quality is not guaranteed; in the prior art 4, the counterweight is added on the outer side of the bottom plate, the counterweight material is a cementing material such as concrete, and a tie bar needs to be arranged between the counterweight material and the bottom plate, so that the manufacturing cost is high.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides an inner counterweight underground structure with simple structure and low cost.
In order to achieve the purpose, the underground structure with the internal counterweight is at least made of an underground structure bottom plate and an underground structure side wall arranged on the underground structure bottom plate; the underground structure bottom plate is provided with a counterweight filling material layer, and the counterweight filling material layer is provided with an underground structure bottom plate surface layer.
Furthermore, the underground structure counterweight filler is made of harmless, stable, self-weight and low-price materials such as plain soil, broken stone and/or slag, so that the manufacturing cost is reduced.
In order to achieve the purpose, the utility model discloses a construction method of interior counter weight underground structure, the method be: and after the construction of the bottom plate and the side wall of the underground structure is finished, filling a counterweight filler in the underground structure, and constructing a bottom plate surface layer of the underground structure after the construction of the counterweight filler by layering and compacting is finished. The underground structure counterweight filler can be plain soil, broken stone and slag.
The utility model discloses interior counter weight underground structures has harmless, from interior counter weight filler such as plain soil, rubble, slay that heavy, the low price characteristics of having through setting up inside underground structures to solve the higher regional underground structures anti problem of floating of groundwater level, have good practicality and economic nature.
Drawings
FIG. 1 is a schematic view of an internally weighted underground structure;
the underground structure comprises an underground structure bottom plate 1, an underground structure side wall 2, an underground structure counterweight filler 3, an underground structure bottom plate surface layer 4, a terrace A and an underground water level B.
Detailed Description
The invention is further described with reference to the accompanying drawings.
Example one
As shown in fig. 1, the inner-weighted underground structure of the present embodiment includes an underground structure bottom plate 1, an underground structure side wall 2, an underground structure weighting filler 3, and an underground structure bottom plate surface layer 4. Wherein, the terrace A and the ground water level B are both higher than the bottom plate surface layer 4 of the underground structure.
Wherein, the underground structure counterweight filler 3 adopts broken stone and slag.
Example two
The inner counterweight underground structure comprises an underground structure bottom plate 1, an underground structure side wall 2, an underground structure counterweight filling material 3 and an underground structure bottom plate surface layer 4.
Wherein, the underground structure counterweight filler 3 adopts plain soil, broken stone and slag.
In conclusion, the utility model aims at solving the anti-floating problem of underground structures in regions with higher underground water level by arranging the inner counterweight filler such as plain soil, gravels and slag which have the characteristics of harmlessness, self-weight and low price in the underground structures, and has good practicability and economy. The thickness of the underground structure counterweight filler 3 can be determined by calculation according to the buried depth of the underground structure and the underground water level elevation.
The utility model discloses building method of interior counter weight underground structure, the method be: and after the construction of the bottom plate and the side wall of the underground structure is finished, filling a counterweight filler in the underground structure, and constructing a bottom plate surface layer of the underground structure after the construction of the counterweight filler by layering and compacting is finished.
The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
