Abstract
The utility model relates to a water level measurement device for a foundation pit dewatering well. The water level measurement device is characterized by comprising a multimeter, two wires, probes for the multimeter and a counter weight, wherein both ends of each wire are respectively connected with a probe for the multimeter, and the probe for the multimeter at one end of each wire is used for contacting with the water level in the well, while the probe for the multimeter at the other end is inserted into a probe jack of the multimeter; and the two probes for the multimeter at the end in contact with the water level in the well are fixed on the counter weight through an insulating water-proof adhesive tape. Compared with the prior art, the water level measurement device has the obvious advantages of accurate and reliable measurement data, simple equipment material, extremely lower equipment cost, convenience in repair, frequent use, and the like.
Description
Technical field
The utility model relates to a kind of base pit dewatering well measurements water level device.
Background technology
In deep foundation pit construction processes such as building foundation pit, subway station, generally all need carry out base pit dewatering, and the accurate direct relation excavation of foundation pit safety whether of the measurement of water level.Because excavation of foundation pit to the water level data requirement in time, accurately, so the water level measuring frequency ratio is higher, conventional artificial lining rope amount method leans on people's subjective judgement often to cause the waterlevel data deviation very big, has very big potential safety hazard.And present on the market limnograph; It is bigger to pop one's head in; Cost of equipment is very high, and the ring flange that it is managed in measuring the precipitation well, in regular meeting tangles well, drawing water during dynamic water level causes instrument damage; And in a single day damage the equipment that just must more renew again, so it is unfavorable for measuring the water level in the precipitation well.
Summary of the invention
In order to solve the shortcoming of prior art, the utility model technology provides a kind of base pit dewatering well measurements water level device that accurately, can frequently use.
The utility model solves the technical scheme that relevant issues adopted: base pit dewatering well measurements water level device, and its difference is: it comprises that multimeter, 2 wires, multimeter are with probe, counterweight; The two ends of every wire all are connected with multimeter with probe, wherein the multimeter of electric wire one end with probe be used for well in the water surface contact, the multimeter of an other end is with the probe insertion of probe insertion multimeter; Contact with the water surface in the well end 2 multimeters with the probe be fixed on the counterweight through the insulative water-proof adhesive tape.
With prior art relatively the utlity model has measurement data accurately, reliable, equipment and materials is simple, equipment cost is extremely low, it is convenient to repair, and remarkable advantage such as can frequently use.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment base pit dewatering well measurements water level device.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further.
As shown in Figure 1, the utility model embodiment base pit dewatering well measurements water level device, it comprises that multimeter 4,2 wires 2, multimeter are with probe 3, counterweight 1; The two ends of every wire 2 all are connected with multimeter with probe 3, wherein the multimeter of electric wire 2 one ends with probe 3 be used for well in the water surface contact, the multimeter of an other end is with the probe insertion of probe 3 insertion multimeters 4; 2 multimeters of an end of contacting with the water surface in the well are fixed on the counterweight 1 through the insulative water-proof adhesive tape with probe 3, and counterweight 1 can adopt the 10cm reinforcing bar first-class, but notices guaranteeing that multimeter is with probe and steel bar end insulation.
The method of application of the utility model embodiment base pit dewatering well measurements water level device is: when measuring water level; Open multimeter to ohms range; Insert multimeter to the multimeter of 2 wires, one end wherein with probe, slowly put into precipitation well after being fixed on the reinforcing bar counterweight with popping one's head in to the multimeter of the other end of 2 wires, this process is wanted the observation multimeter panel board pointer while putting; If pointer one is beated; Stop to put into, mark and take out length mark or the direct wire length of putting into of measuring that number of reinforcing bar counterweight performs in advance, measure water level depth at once.
Above content is the further explain that combines concrete embodiment that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
