Abstract

The utility model discloses a floating force releasing structure for deep substrate bottom plate, which is characterized by comprising an earthwork cloth layer, a broken stone inverse filter layer, a slurry insulation layer, a concrete protective layer and a waterproof layer which are paved from down to up in turn, wherein the earthwork cloth layer is paved above natural soil layer; a porous filter tube is provided in the broken stone inverse filter layer. The utility model can release and weaken the floating force of underground water on the bottom plate and improve the waterproof ability of the substrate bottom plate, thereby resolving the anti-floating and anti-filtration problems of the substrate bottom plate of underground engineering. The floating force releasing structure has simple and safety construction, reduced labor strength of workers, improved construction efficiency and reduced maintenance cost.

Description

Deep foundation base plate buoyancy releasing structure
Technical field
The utility model belongs to building underground engineering construction technical field, relates in particular to a kind of deep foundation base plate buoyancy releasing structure of constructing under the deep foundation base plate.
Background technology
The conventional construction of deep foundation base plate at present is a direct construction reinforced bar concrete structure base plate on basic concrete bed course.Shi Gong sole plate will directly bear phreatic buoyancy like this, to cause the structure floating distortion, problems such as crack appear in wallboard, beam column handing-over position, in addition, with regard to its construction itself, concrete in mass has complex process and organizes loaded down with trivial details construction characteristic, has certain potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of deep foundation base plate buoyancy releasing structure, strengthened the waterproof ability of sole plate when guarantee discharging, weakening underground water, solved underground construction sole plate anti-floating and impervious two hang-ups the buoyancy of base plate.
The technical scheme of the utility model technical solution problem is as follows:
A kind of deep foundation base plate buoyancy releasing structure; it is characterized in that; comprise from the bottom to top the geotechnological layer of cloth laid successively, rubble loaded filter, every slurry layer, concrete cover and waterproofing course, described geotechnological layer of cloth is laid on original state soil layer top, in the described rubble loaded filter porous water filtration pipe is set.
The utility model adopts the layering laying construction, and material layerings in certain sequence such as geotextiles, PVC filter pipe, rubble, sand are laid, and brings into play its function separately.Underground water is oozed to the buoyancy releasing structure last, and the continuous infiltration by geotextile, sandstone flows into collecting well along pipe again until filter pipe, with water pump underground water is extracted out at last, discharges the buoyancy of underground water to sole plate with this.
Its beneficial effect is as follows: buoyancy releasing structure work progress handy and safe, alleviate construction operation personnel's labour intensity, and improved construction efficiency; Draw materials conveniently, replace steel concrete in the past, make work progress obtain simplifying, and reduce spillage of material with materials such as geotextile, sandstones; In addition, the waterproof effect of buoyancy releasing structure has guaranteed the impervious function of underground engineering structure, has reduced to reprocess and has mended slurry work, has saved maintenance cost.
Description of drawings
Fig. 1 is the utility model section structure schematic diagram;
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, the utility model deep foundation base plate buoyancy releasing structure is arranged at sole plate 9 times, comprise that from the bottom to top the geotechnological layer of cloth 1 laid successively, rubble loaded filter 2, plastic sheeting are every slurry layer 3, concrete cover 4 and waterproofing course 5, described geotechnological layer of cloth 1 is laid on original state soil layer 6 tops, in the described rubble loaded filter 2 porous water filtration pipe 7 is set, the periphery of described porous water filtration pipe 7 is coated with geotextiles 71, and the outer ring of geotextiles 71 is provided with one deck coarse sands layer 8, and the thickness of coarse sands layer 8 is 5cm; Covered with plastic film on the described waterproofing course 5.The thickness of described rubble loaded filter 2 (containing french drain thickness) is 60~80cm, and the thickness of described concrete cover 4 is 7~10cm.
The concrete form of construction work of the utility model can be divided into french drain district construction (groove) and standard regions construction.As follows for french drain district its working procedure of constructing: as to dig the filter pipe → benefit of filling out rubble, sand → lay outsourcing geotextiles to trench bottom → laying geotextiles → shop and fill out rubble, the closely knit groove of sand; Construct for typical floor: dig to substrate → laying geotextiles → shop and fill out rubble, sand → laying plastic sheeting → concreting topping, to finish the construction of whole buoyancy releasing structure.
