Background technology
With the quickening of urbanization process and the needs of urban construction and development, the underground space is developed, passes through space shape
Vertically optimization overcomes "urban disease" to state, it has also become the important layout principle and development trend of urban development.The underground space can be effective
Expansion space supply, improve Urban Efficiency, reduce ground occupancy, protection ground landscape and environment, being made that significant contribution.For
For building unit, for the underground space because it is in underground, engineering geological condition is often more complicated, not only soil layer, sand ovum
Layer is more, and the engineering project underground water having is very abundant, thereby increases and it is possible to also has dark creek, underground river etc., therefore, building unit
In addition to underground exterior-protected structure to be constructed, often there are deep foundation pit precipitation engineering, and level of ground water in dewatering project dewatering well
The measurement of level of ground water elevation in the definitely too busy to get away water level well of change observation.
At present, traditional measuring method is that survey crew estimates with sensation or uses professional limnimeter, estimates and causes survey
The amount degree of accuracy substantially reduces, professional limnimeter it is expensive, maintenance cost is high, is easily damaged.

Embodiment
For features described above and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing,
It is described in detail below.
As shown in Fig. 1 ~ 5, a kind of auxiliary Simple measurement device for surveying water level well level of ground water, including steel tape 1 fill with internal
Be filled with the plastic bottle 2 of some sandstones 15, water, be connected between the steel tape and plastic bottle through iron wire 3, one end of the iron wire with
The bottle cap of plastic bottle is connected, and the other end of the iron wire bends to the crotch 4 for catching on steel tape hook.
In the utility model embodiment, the center of bottle cap 5 of the plastic bottle offers a hole 6, and the one of the iron wire
Closure inside is stretched into end along hole, and the iron wire for stretching into closure inside is bent at the scrobicular ring 7 of round and embedded bottle cap inner top;System
When making, spudded in hole with quincunx screwdriver at the bottle cap center of plastic bottle, one section of No. 18 iron wire is cut with pincers knife(Should not be too
It is long, 10cm~20cm)Through after hole, one end that iron wire stretches into bottle cap is converted into round insertion bottle cap screwing internal thread by hand
In scrobicular ring at after screw bottle cap, while by the iron wire other end through being also converted into hook solid firmly hook by hand after the hook of steel tape
Firmly.
In the utility model embodiment, the length of steel tape can be selected according to measurement demand, and sandstone can topple over water
Go out or increase to be adjusted, so that the plastic bottle average weight, the chi bar that can float on water surface and can traction steel tape is kept
Naturally hang.
In the utility model embodiment, one end of the iron wire and the bottle cap of plastic bottle are intertwined and connected, and iron wire is No. 18
Iron wire.
In the utility model embodiment, the bottle cap of the plastic bottle include end face 8 and with end face is fixed is integrated
Circumferential side wall 9, the inwall of the circumferential side wall are provided with the internal thread being spirally connected with bottleneck, the inner surface of the end face be installed with
The coaxial circumference convex portion 10 of circumferential side wall, scrobicular ring is formed between the circumference convex portion and circumferential side wall;Stretched into along hole in bottle cap
The iron wire in portion can circumferentially convex portion lower edge insertion scrobicular ring, a resigning through hole can also be opened up in all portions of circumference convex portion
16, iron wire enters scrobicular ring along resigning through hole.
In the utility model embodiment, the plastic bottle is mineral water bottle, and bottle cap is mineral water bottle cap.
A kind of application method of the auxiliary Simple measurement device for surveying water level well level of ground water, is carried out according to the following steps:
(1)Draft h1 is determined:By inside be filled with some sandstones, the plastic bottle of water be positioned over dress water bucket in,
Weight by testing and adjusting sandstone in bottle makes plastic bottle vertically not float on the water surface obliquely, now determines plastic bottle sinking
Depth below the water surface is draft h1;
(2)The initial elevation H1 measure of well head 11 of water level well 13:According to the bench mark at building engineering construction scene, water is used
Quasi- instrument measures the initial elevation H1 for the water level well well head for needing to measure;
(3)The hook of steel tape(At zeromark)Catch on the iron wire being connected with plastic bottle, the portable steel tape of a people, control
The speed and depth of decentralization are adjusted, another people holds the lowering velocity and depth of the control plastic bottle of leather strap 14 of steel tape;
(4)When plastic bottle touches groundwater level 12 and reaches draft, leather strap is become by vertical exceptionally straight shape before
Fluffy is bent, survey crew should stop transferring leather strap, and plastic bottle touches groundwater level and can also sent out when reaching draft
Go out larger underwater sound resonant and echo;
(5)Record water level depth h:Reach step(4)Shi Jilu now steel tape leather strap correspond to pithead position at
Scale reading h2, along with the length h3 at bottom of bottle to the hook of steel tape of plastic bottle, then draft h1 is subtracted, be this
Water level depth h of the groundwater level apart from the initial elevation of well head in Shi Shuiwei wells;
(6)By step(2)The initial elevation H1 obtained subtracts step(5)The water level depth h of acquisition, obtain tested underground water
Water level elevation H2, H2=H1-h=H1- in face(h2+h3-h1).
In the utility model embodiment, in step(4)In, after plastic bottle reaches draft, survey crew should
Stop decentralization leather strap, now pin at the leather strap scale concordant with well head face, while lifting leather strap observes leather strap several times repeatedly
Vertical exceptionally straight degree is confirmed.
The auxiliary Simple measurement device for surveying water level well level of ground water construction particularly underground construction suitable for needing
Want the level of ground water in subsidiary water level well and during without professional level measuring instrument, especially level of ground water is buried in deep water level well
Easier, practical and more aobvious advantage under conditions of the relatively depth of Tibetan, device overall structure is simple, and manual simple to install is convenient, cost
It is cheap to have saved cost, and energy repetitive cycling uses, and can meet the difference of different levels of ground water by the selection of steel tape length
Measurement demand, efficiency high few by external interference factor, measurement result are accurate.
The utility model is not limited to above-mentioned preferred forms, and anyone can obtain under enlightenment of the present utility model
Go out other various forms of auxiliary Simple measurement devices for surveying water level well level of ground water.It is all according to present utility model application the scope of the claims institute
