Building foundation pit is the below ground space that the construction for carrying out building foundation or underground structure is excavated.Under normal circumstances, the design elevation of on-the-spot groundwater table at the bottom of higher than Foundation Pit, when excavation of foundation pit, water can flow to foundation ditch, causes and cannot continue construction, also cannot guarantee workmanship simultaneously, therefore needs to carry out foundation ditch and falls draining.Existing foundation ditch falls drainage pattern and is mostly in dewatering well bottom water pump and attached circuit are set, and by water pump, water in dewatering well is upwards pumped.Aforesaid way very easily causes water pump to damage, and, cannot effectively control precipitation water level, also need multiple water pumps manually to supervise wasting manpower and material resources; Especially in the time that basic raft board concrete is built, also need this position to carry out specially treated, be unfavorable for basic raft board concrete waterproof.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of foundation ditch to fall draining automatic control system, and it can be realized foundation ditch and automatically fall draining, easy construction, automaticity is high, and efficiency is high, and basic raft board concrete can one-time-concreting moulding, is beneficial to base plate waterproof.
The utility model solves its technical problem and takes following technical scheme to realize:
Draining automatic control system falls in a kind of foundation ditch, it is characterized in that: mainly formed by suction pump, control cabinet, drinking-water pipe, detector tube, water level elevation probe and filter cage, drinking-water pipe and detector tube are longitudinally plugged in the dewatering well of below, basis, the bottom of drinking-water pipe is installed and is connected filter cage, the upper end that drinking-water pipe stretches out dewatering well is connected with suction pump, in detector tube, be fitted with water level elevation probe, this water level elevation probe is connected to the circuit control unit in control cabinet, completes by circuit control unit control suction pump the action of drawing water.
And described water level elevation probe comprises low water stage probe, middle water level probe and high water level probe, this low water stage probe, middle water level probe and high water level probe are connected to respectively the liquid level relay of circuit control unit.
And described filter cage is made up of support frame outer wrap gauze wire cloth.
And, on described drinking-water pipe and detector tube, welding sealing steel loop, this water-stopping steel ring position is at the basic raft board concrete middle part on dewatering well top.
Advantage of the present utility model and good effect are:
1, draining automatic control system falls in this foundation ditch, when the groundwater table in dewatering well rises to desired location, while rising to high water level, suction pump starts automatically, starts precipitation, in the time that water level drops to lower than desired location, suction pump stops automatically, thereby realizes foundation ditch and fall the automatic control of draining.
2, draining automatic control system falls in this foundation ditch, and suction pump is arranged to the basic top of construction, is not only convenient to management compared with the mode of suction pump being put into dewatering well of transmission, and, use manpower and material resources sparingly.
3, draining automatic control system falls in this foundation ditch, is connected and installed with filter cage in the bottom of drinking-water pipe, thereby the foreign material in underground water are effectively filtered, and prevents that drinking-water pipe from stopping up, and guarantees to fall safe, the efficiently construction of draining.
4, draining automatic control system falls in this foundation ditch, dewatering construction to water level drop to bottom land with upper/lower positions after, carry out foundation pad construction, carrying out before foundation pad construction, first will in dewatering well well casing, be filled to bottom land absolute altitude with cun stone, and on drinking-water pipe and detector tube, weld sealing steel loop, then the basic raft board concrete of constructing, water-stopping steel ring position is at basic raft board concrete middle part, carry out after foundation pad construction, this falls drainage system and still can work on, in waterproof and basic raft board concrete work progress from now on, this position needn't be considered separately, directly construction.
5, the utility model scientific structure design is reasonable, can realize foundation ditch and fall the automatic control of draining, and guaranteed water level is 50cm under foundation ditch, automaticity is high, uses manpower and material resources sparingly, and falls drainage efficiency high, safe, be that draining automatic control system falls in a kind of foundation ditch with higher innovation.

The specific embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
Draining automatic control system falls in a kind of foundation ditch, and it is mainly made up of suction pump 1, control cabinet 3, drinking-water pipe 7, detector tube 4, water level elevation probe 9 and filter cage.Drinking-water pipe and detector tube are longitudinally plugged in the dewatering well 10 of below, basis.The bottom of drinking-water pipe is installed and is connected filter cage, and filter cage is made up of support frame 12 outer wrap gauze wire cloths 11.The upper end that drinking-water pipe stretches out dewatering well is connected with suction pump, is fitted with water level elevation probe in detector tube, and this water level elevation probe is connected to the circuit control unit in control cabinet, completes by circuit control unit control suction pump the action of drawing water.Drinking-water pipe upper end is fixedly mounted with horizontal stand 6, this horizontal stand and suction pump support 2 and control cabinet fixed installation.Between drinking-water pipe and detector tube, be also fixed with horizontal shore 8.On drinking-water pipe and detector tube, weld sealing steel loop 13, this water-stopping steel ring position is at basic raft board concrete 5 middle parts.
