Abstract
The utility model discloses a kind of water burst drainage system for closed deep foundation ditch exploratory hole, comprise connect successively from top to bottom outflow tube, valve, tube connector, accommodation and drainage tube, the bottom of described drainage tube is inserted in exploratory hole, water blockoff structure is provided with at the top periphery of described drainage tube, described water blockoff structure comprises the expansion water-stop ring be arranged on described drainage tube and the pit be formed in around described drainage tube, in described pit, be formed with plugging structure.The utility model can realize the functional in organized water drainage of exploratory hole water outlet, compared with the modes such as, benefit stifled with traditional, stop the phenomenon of underground water slabbing inorganization trickling, solve and affect the problem of bearing capacity of foundation soil because ground bottom land is immersed in water for a long time, and draw materials conveniently, assemble simple, economical and practical.
Description
Technical field
The utility model relates to Foundation Pit Excavation Technique field, particularly a kind of water burst drainage system for closed deep foundation ditch exploratory hole.
Background technology
Along with Chinese national economy and urban construction fast development, urbanization enters a new developing period.High-altitude and Underground Space Resource are more and more developed simultaneously, make corresponding base pit engineering to larger darker trend development, become one of focus of geotechnical engineering circle concern, in a large amount of bridges, track traffic, super highrise building engineering practice, the Foundation Design of China obtains fast development, excavation of foundation pit be basis and underground engineering construction in a traditional subject.The content that it relates to is more, it is a complicated Geologic Problems in key, both self-strength and the stability of foundation ditch had been related to, contain again the problem of geological environment and social influence, therefore in the construct and design planning stage of object of construction production, the mode of holing can be taked to carry out geologic prospect planning to build place, to find out, to analyze, to evaluate the palegeology environmental characteristic and geotechnical engineering condition of building place.And after pit earthwork is excavated to substrate, in the exploratory hole that early stage stays because of geologic prospect, have a large amount of press water to gush out, bring larger difficulty to foundation construction operation.To the on-the-spot conventional way of this type of exploratory hole water burst be: adopt certain material to carry out shutoff process, but this way is on the one hand because hydraulic pressure in hole causes more greatly shutoff difficulty, has current unavoidably and oozes out; On the other hand, specific plugging material is adopted can to cause the increase of cost.
Summary of the invention
The utility model provides a kind of water burst drainage system for closed deep foundation ditch exploratory hole for solving in known technology the technical problem that exists, and this device can effectively control current, stops the phenomenon that current in exploratory hole ooze out, and easy for installation, and cost is low.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: a kind of water burst drainage system for closed deep foundation ditch exploratory hole, comprise connect successively from top to bottom outflow tube, valve, tube connector, accommodation and drainage tube, the bottom of described drainage tube is inserted in exploratory hole, water blockoff structure is provided with at the top periphery of described drainage tube, described water blockoff structure comprises the expansion water-stop ring be arranged on described drainage tube and the pit be formed in around described drainage tube, in described pit, be formed with plugging structure.
The bottom of described drainage tube is coated with and is brushed with antirusting paint layer.
The bottom of described drainage tube is wound with flax silk.
Described valve adopts ball valve.
The advantage that the utility model has and good effect are: the unordered water flowed out by exploratory hole in an organized way can be discharged, can ensure the drying bottom foundation ditch, conveniently carry out the construction of follow-up bed course and waterproof; Regulate drain discharge by ball valve, effectively can control current, the current in exploratory hole can not only be drawn, can also the water of drawing be recycled; When the later stage builds raft foundation, cap holes simple to operate, only needs temporary close ball valve and concreting carries out closing rapidly, and closed after respond well leakproof phenomenon.And the utility model is drawn materials conveniently, it is simple, economical and practical to assemble.In sum, the utility model can realize the functional in organized water drainage of exploratory hole water outlet, compared with the modes such as, benefit stifled with traditional, stop the phenomenon of underground water slabbing inorganization trickling, solved and affect the problem of bearing capacity of foundation soil because ground bottom land is immersed in water for a long time.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is drainage portion structural representation of the present utility model.
In figure: 1, outflow tube; 2, valve; 3, tube connector; 4, flexible; 5, drainage tube; 6, exploratory hole; 7, expansion water-stop ring; 8, plugging structure; 9, bed course.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of water burst drainage system for closed deep foundation ditch exploratory hole, comprise the outflow tube 1, valve 2, the tube connector 3, flexible 4 and drainage tube 5 that connect successively from top to bottom, the bottom of described drainage tube 5 is inserted in exploratory hole 6, water blockoff structure is provided with at the top periphery of described drainage tube 5, described water blockoff structure comprises the expansion water-stop ring 7 be arranged on described drainage tube 5 and the pit be formed in around described drainage tube 5, is formed with plugging structure 8 in described pit.
In the present embodiment, described drainage tube adopts galvanized pipe, causes corrosion to damage for avoiding galvanized pipe long soaking time in water, is coated with and is brushed with antirusting paint layer, thus improve the application life of whole drainage system in the bottom of described drainage tube.In order to increase galvanized pipe exterior rugosity, be wound with flax silk in the bottom of described drainage tube, make in galvanized pipe patchhole more firm, compactness is better.In the present embodiment, plugging structure 8 adopts water glass to admix cement formation or adopts sealing agent blending cement to be formed.Described valve 2 adopts ball valve.
The utility model adopts valve as the gauge tap of drawing-off water and flow regulator, connect a plastic flexible pipe (length can be determined according to on-site actual situations) in the upper end of drainage system simultaneously, just the current of drawing can be discharged in a organized way, or carry out collection recycling.Usually, the ball valve of drainage system and outflow tube mouth should be made to expose bed course 9 when bed course, waterproof and topping are constructed, so that the tissue of current and discharge when bed course 9 is constructed.Build after near drainage system at raft board concrete, ball valve is closed, and the plastic flexible pipe be arranged on outflow tube is removed, under utilizing concrete rapidly whole device to be enclosed in raft plate.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
