Abstract
The invention relates to a pulp concentration pool underground base structure with an anti-floating function, which comprise a pulp concentration pool, a pipeline corridor and a bottom flow pump station. The pulp concentration pool underground base structure is characterized in that a water seepage passage with good water permeability, composed of metalling layers, is paved under a backfill soil layer at the periphery of the base angle of the pulp concentration pool; the water seepage passage is communicated with a water seepage well which is composed of a well cylinder embedded in the water seepage passage of the metalling layers, and a water pump arranged in the well cylinder; and the water pump is connected with a drain pipe. By using the structure, the anti-floating requirements are satisfied, and at the same time, not only the project investment is reduced, and the construction period of a project is reduced, but also underground water can be effectively utilized.
Description
Technical field
The invention belongs to the underground structure technical field of ore dressing concentration basin underground foundation structure, particularly is a kind of ore pulp concentration basin underground foundation structure with anti-floating function.
Background technology
According to " Design Code of Reinforced Concrete " regulation, in carrying out underground foundation structure building design process, must consider the buoyancy influence factor of underground water to underground structure.By traditional in the past design experiences, the form of structure of often taking to increase structure counterweights such as concentration basin, core pool in carrying out underground foundation structured design processes such as ore pulp concentration basin, core pool is offset phreatic buoyancy effect, thereby slurry in emptying the pond such as concentration basin, core pool is overhauled under this least favorable state, and the underground pipeline vestibule that underground foundation structures such as assurance and concentration basin, core pool are attached thereto, production pipeline etc. is not destroyed.The form of structure of taking to increase the structure counterweight is offset phreatic buoyancy, must increase the concrete amount of structure.Therefore, in the structure work progress, shared place is big, long construction period, engineering one-time investment height, groundwater resources can not well utilize.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can offset phreatic buoyancy effectively, reduce the concrete engineering construction amount of ore pulp concentration basin underground foundation structure building counterweight part, reduce construction investment, the ore pulp concentration basin underground foundation structure that underground water is got effective use of production with anti-floating function.
The objective of the invention is to realize by following technical proposals:
Ore pulp concentration basin underground foundation structure with anti-floating function of the present invention, comprise the ore pulp concentration basin, pipeline vestibule, underflow pumping plant, it is characterized in that: below the back fill course of base angle, ore pulp concentration basin basis periphery, lay the penetrating passage that the macadam by good water permeability constitutes, this penetrating passage is connected with negative well, described negative well is by the pit shaft of imbedding in the macadam penetrating passage, and the water pump that is located in the pit shaft is formed, and this water pump is connected with gutter.
The thickness of described macadam is 500-1500mm, and width is 1000-2000mm.
The pit shaft of described negative well is made of steel pipe or precast concrete pipe, and permeable hole is evenly arranged on the pit shaft whole body, and the pit shaft appearance is wrapped up with the good geotextiles of water permeability.
The wellbore bottom of described negative well is imbedded 200--400mm in the macadam penetrating passage,, upper wellbore 400-600mm above ground level.
The invention has the beneficial effects as follows:
Because the present invention has adopted and laid the penetrating passage that the macadam by good water permeability constitutes below the back fill course of base angle, ore pulp concentration basin basis periphery, and penetrating passage is connected with negative well, the infiltration of on-site underground piping system, natural rainwater, original underground water etc. converge long-pending, be drained into the ring grid by water pump in penetrating passage and the negative well, when satisfying the requirement of anti-floating power, both reduced construction investment, reduced the construction period of engineering, underground water is got effective use of production.
Description of drawings
Fig. 1 arranges the structure chart of penetrating passage and negative well for ore pulp concentration basin of the present invention.
Fig. 2 is Figure 1A-A sectional view.
Fig. 3 is Figure 1B-B penetrating passage and pit shaft sectional drawing.
Fig. 4 is the sectional drawing of pit shaft.
The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
As shown in Figure 1, 2, ore pulp concentration basin underground foundation structure with anti-floating function of the present invention, comprise ore pulp concentration basin 2, pipeline vestibule 5, underflow pumping plant 4, it is characterized in that: below the back fill course 7 of ore pulp concentration basin 2 basic 6 base angle peripheries, lay the penetrating passage that the macadam 1 by good water permeability constitutes, this penetrating passage is connected with negative well 3, described negative well 3 is by the pit shaft of imbedding in macadam 1 penetrating passage 9, the water pump 8 that is located in the pit shaft 9 is formed, and this water pump 8 is connected with gutter.The pit shaft 9 of negative well of the present invention is made of steel pipe or precast concrete pipe, and permeable hole 10 is evenly arranged on the pit shaft whole body, and pit shaft 9 appearances are with the good geotextiles parcel of water permeability, in order to avoid stop up.The degree of depth that pit shaft 9 bottoms of its negative well are imbedded in macadam 1 penetrating passage is preferably in 200--400mm, uses backfill 7 landfills then, and upper wellbore is wanted 400-600mm above ground level during landfill, draws water to make things convenient for water pump, as shown in Figure 3, Figure 4.
The present invention is provided with penetrating passage and negative well outside concentration basin underground foundation structure in design process, in negative well, also install by pulsating pump, the water pump that this water pump adopts liquid level control to start, its liquid level control height can overcome buoyancy force of underground water with concentration basin body deadweight under the state of emptying and guarantee that safe handling is as the criterion, and produces use by the underground water that water pump is extracted out through the recirculated water pipe network that gutter is drained into plant area.Both reduced construction investment, reduced the construction period of engineering, underground water is got effective use of production.
The present invention is in order to satisfy the anti-floating power requirement of concentration basin, and it preferably builds up 500-1500mm with the thickness of the macadam of penetrating passage, and width is 1000-2000mm.The macadam of its penetrating passage adopts the FIX CHARGE RATE ABOUT THE WASTE ROCK rubble, and not only cost is less, and can save the concrete of a large amount of counterweight part, has reduced the one-time investment of engineering.
The present invention is not only applicable to ore pulp concentration basin underground foundation structure, but also is suitable for the construction of underground foundation structure such as core pool, reservoir.
