The utility model has the characteristics of construction convenience, operation are simple and easy, with low costs, can improve the security of foundation ditch engineering operation greatly.
Description
Technical field
The utility model belongs to building engineering field, relates generally to a kind of simple observation device of Water Level in Foundation Pit.
Background technology
With the growing tension of urban land area, various high-rise, super high rise buildings are rised sheer from level ground, especially economic hair
It reaching, the low flat Pearl River Delta area of topography, most of ground is that littoral facies and river and lake interact the weak cohesive soil of deposition, engineering
Matter and hydrogeologic condition are all complex, and problem of groundwater is very prominent, and larger impact is produced to engineering construction, are easy to draw
Send out engineering accident.
Deep foundation pit precipitation is the quite crucial process of base pit engineering one, and whether deep foundation pit precipitation is successfully directly related to
The whether successful conditionality factor of deep pit digging.The monitoring of precipitation is also to be directly related to deep pit monitor, periphery construction
Build object safety and construction safety.
When higher or there is the location of abundant ground backwater to carry out base pit engineering earth excavation and foundation construction to level of ground water
When, the phenomenon that water-bearing layer is cut-off, and earth's surface and underground water largely invade can be often encountered, therefore not only earth excavation is difficult, work efficiency
Very low, side slope is easy to cave in, and impregnates be easy to causeing, destroys the phenomenon that foundation soil and foundation bearing capacity reduction, to
Engineering can be caused to build up rear building and generate a large amount of differential settlements, works is made to crack or destroy.Or occur piping, quicksand,
Bottom heave cheats phenomena such as outer stratum excessive deformation, causes to destroy stability of slope, influence neighbouring buildings or structures it is safe to use with
Engineering is smoothed out.
Therefore, the precipitation of foundation pit is often the important technical project that must be solved first before excavation, foundation pit water
Position monitoring is also just particularly important.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a kind of Water Level in Foundation Pit and simply observe dress
It sets, which has the characteristics that easy for construction, operation is simple, at low cost, substantially increases the safety of base pit engineering operation.
As above conceive, technical solution is used by the utility model：A kind of simple observation device of Water Level in Foundation Pit, feature
It is：Including infiltration floral tube, float, weight and hand-held laser rangefinder；Float, bottom end installation weight built in the infiltration floral tube
Hammer, top extend transversely through reinforcing bar.
A diameter of 50mm of above-mentioned infiltration floral tube.
Above-mentioned float is circle, a diameter of 30mm.
The length of above-mentioned reinforcing bar is more than dewatering well diameter 200mm.
Weight >=2Kg of above-mentioned weight.
The utility model has the following advantages and good effect：
1, the utility model floral tube that will seep water is fixed on the borehole wall, and the water in dewatering well is by the hole seeped water on floral tube into infiltrating
In spray pipe, you can ensure that pipe well is consistent with water level in infiltration floral tube.
2, float built in the infiltration floral tube of the utility model, buoys float water surface inside infiltration floral tube, is swashed with hand-held
Optar is vertically beaten can show real-time deep basal pit water level and infiltration floral tube elevation on float, therefore can observe in real time
Precipitation water level elevation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below by specific embodiment, the utility model is described in further detail, following embodiment be it is descriptive, no
It is restrictive, protection scope of the present invention cannot be limited with this.
As shown in the figure：A kind of simple observation device of Water Level in Foundation Pit, including PVC infiltrations floral tube 2, float 3, weight 4 and hand-held
Formula laser range finder 7.Float 3, bottom end installation weight 4, top extend transversely through reinforcing bar 1 and are oozed built in the PVC infiltrations floral tube
Spray pipe verticality adjusts and carries out integral reinforcing.A diameter of 50mm of above-mentioned PVC infiltrations floral tube.Above-mentioned float is round
The low float of light transmittance, a diameter of 30mm.The length of above-mentioned reinforcing bar is more than dewatering well diameter 200mm.The weight of above-mentioned weight
≥2Kg。
The utility model carries out easy device installation when precipitation well construction finishes and starts draining, and construction procedure is：
1,4m mono- is saved the solid rope in the infiltration floral tube lower parts Φ 50PVC passes through the binding of pvc pipe hole not less than 2Kg weights
Hammer, inside are put into the lower float (diameter 30mm) of light transmittance, and then tube bottom is blocked, and prevents water level too low, float is blown out
PVC infiltration floral tubes.
2, by tie up weight, install float PVC infiltration floral tube be slowly sent to 6 bottom of dewatering well along pipe well wall, because often section manage
Length is limited, need to be attached with PVC casings in nozzle position between two section floral tubes, and PVC infiltration floral tubes are transferred to bottom weight and drop
Stop when well 6 bottom drainage layer, 5 spacing 50cm, ensures that PVC infiltration floral tubes are higher by well head 30cm.
3, PVC infiltration floral tube pores are passed through with 14 reinforcing bars 1 of Φ, allows infiltration flower to naturally droop, rides over dewatering well well head, well head
Absolute altitude is unsatisfactory for corresponding measure being taken to be adjusted when reinforcing bar is set up, and pipe well both sides are grown not less than 20cm respectively, and are carried out
It reinforces.
4, laser can be got on float at the top of PVC infiltration floral tubes with hand-held laser rangefinder 7 in work progress
Level measuring is carried out, to carry out the observation of Water Level in Foundation Pit.
The utility model simple structure, easy to operate, general technical staff can operate, convenient observation in real time.
