Abstract
The utility model discloses an underground water level surface relative elevation simple measuring device inside a foundation pit dewatering well. The underground water level surface relative elevation simple measuring device comprises a plurality of supports fixed to the side wall of the dewatering well through supporting rods, wherein the supports are vertically arranged in parallel at intervals. A circular ring is installed at the end of each support. The centers of all the circular rings are arranged concentrically. A vertical hollow vertical rod arranged in the vertical direction penetrates through the circular rings and can freely slide inside the circular rings. A floating ball is installed at the bottom of the vertical hollow vertical rod. A vertically-arranged water level gauge is installed on the supporting rods located at the upper portion of a well moth. The water level gauge is opposite to the vertical hollow vertical rod. Relative elevation scales within the dewatering depth range are arranged on the water level gauge. A pointer is perpendicularly fixed to the upper portion of the vertical hollow vertical rod and horizontally points to the scales of the water level gauge within the upper and lower limit range of scale reading of the water level gauge. The underground water level surface relative elevation simple measuring device is easy to manufacture and high in measuring precision and facilitates data reading.
Description
Technical field
The utility model relates to relative altitude Simple measurement device, and the utility model relates in particular to underground water table surface relative altitude Simple measurement device in base pit dewatering well.
Background technology
In the time that in foundation ditch, underground water table surface is positioned at foundation platform depth range, when foundation ditch entirety heavy excavation, underground water table does not affect construction, but in the time that foundation platform excavates, just needs precipitation could construct to reasonable depth.When construction, often adopt the mode that some dewatering wells are set between the cushion cap that does not affect construction in foundation ditch to reach the object of lowering of watertable, convenient and economical.This kind of method is simply effective, but weak point is the elevation that Precipitation Process underground water table is concrete and cannot measures, follow-up cushion cap excavation work cannot be determined concrete digging time, carry out in advance water level and do not drop to the degree of depth, hysteresis affects the duration, can only after starting, precipitation adopt the mode that digs interim observation hole to observe at foundation ditch unique point position, if also need to dig larger area observation hole when the cushion cap degree of depth is larger, after finishing, observation also wants secondary backfill, will consume a large amount of manpowers and mech time.While directly measurement in dewatering well, again without better measuring method and survey instrument can ensure measuring accuracy.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of and makes simply, and measuring accuracy is high, and data read the interior underground water table of a kind of base pit dewatering well surface relative altitude Simple measurement device easily.
In order to achieve the above object, the technical solution adopted in the utility model is:
Underground water table surface relative altitude Simple measurement device in a kind of base pit dewatering well of the present utility model, it comprises the support that is fixed on the multiple upper and lower parallel interval setting on dewatering well sidewall by support bar, an annulus is installed in the end of each support, all centres settings of annulus, a vertical hollow vertical rod vertically arranging is passed multiple annulus and can slide and arrange at multiple annulus internal freedoms, bottom in described vertical hollow vertical rod is provided with ball float, the gauge of vertical setting is installed on the described support bar that is positioned at well head top, described gauge and vertical hollow vertical rod are oppositely arranged, on described gauge, be provided with relative altitude scale within the scope of precipitation depth, the top of vertical hollow vertical rod that what pointer was vertical be fixed on and level are pointed to gauge scale place and on gauge scale reading, in lower range.
The beneficial effects of the utility model are: make simply, measuring accuracy is high, and data read conveniently, and device high strength and deformation is affected by environment little, can the long period for monitoring the situation of change of underground water table, cost is low, can have enough to meet the need use.Can not adopt mode artificial or mechanical equivalent of light excavation observation hole to reach the object of grasping underground water table, facilitate feasiblely, save and drop into, remarkable in economical benefits.Can effectively ensure the duration, for procedure arrangement provides authentic data.
Brief description of the drawings
Accompanying drawing is the structural representation of underground water table surface relative altitude Simple measurement device in a kind of base pit dewatering well of the present utility model.
Embodiment
Underground water table surface relative altitude Simple measurement device in a kind of base pit dewatering well of the present utility model as shown in drawings, it comprises the support 6 that is fixed on the multiple upper and lower parallel interval setting on dewatering well sidewall 4 by support bar, an annulus is installed in the end of each support 6, all centres settings of annulus, a vertical hollow vertical rod vertically arranging 3 is passed multiple annulus and can slide and arrange at multiple annulus internal freedoms, in the bottom of described vertical hollow vertical rod 3, ball float 7 is installed, the gauge of vertical setting is installed on the described support bar that is positioned at well head top, described gauge and vertical hollow vertical rod 3 are oppositely arranged, on described gauge 2, be provided with relative altitude scale within the scope of precipitation depth, the top of vertical hollow vertical rod 3 that what pointer 1 was vertical be fixed on and level are pointed to gauge 2 scale places and on gauge 2 scale readings, in lower range.
The installation and application of this device is as follows:
1. first support 6 is required to be fixed on dewatering well sidewall 4 according to precipitation depth, the annulus size of end is slided and does not shake and be advisable at internal freedom with vertical hollow vertical rod 3, and the center of all support 6 annulus requires with one heart.Support 6 installation before 4 constructions of dewatering well sidewall;
Gauge 2 dewatering well sidewall 4 constructed and fix after install, require straight up, and with the vertical hollow vertical rod 3 corresponding settings in position;
3. vertical hollow vertical rod 3(ball float 7 wouldn't be inflated) from top to bottom successively through the annulus on support 6, above ball float 7 is probably positioned at water level 8 when close together, make ball float 7 float over water level surface from hollow vertical rod 3 upper end inflations, 3 tops of shutoff vertical rod afterwards prevent gas leakage;
4. vertical hollow vertical rod 3 top pointers 1 are firmly installed, pointer 1 and level vertical with vertical hollow vertical rod 3 pointed to gauge 2 data places of well head place, and within the scope of gauge 2 scale reading upper and lower limits, pointer scope of activities should be within precipitation depth variation range, and has certain abundant amount.Determine that pointer 1 is to length between water level 8 surfaces, provide basis for calculating water level relative altitude.
