Abstract
The utility model relates to a water dropping machine for well point which belongs to the construction dewatering installation. A motor (1) drives to a centrifugal pump (2) which is communicated with a circulating water tank (3) through a T joint, the circulating water tank (3) is communicated with an L-shaped standpipe (13), an ejector (4) inserts into the circulating water tank (3), and a suction hose (5) is communicated with the ejector (4); a plurality of well bore are drilled around a construction foundation area, each well bore is deep enough to go through the depth of foundation into an aquifer (11), a sieve tube (6) with sieve (10) is inserted into each well bore, and a collector pipe (7) on the ground (8) is communicated with each sieve tube (6) and then is communicated with the hose (5). A line pipe (9) arranged inside the funnel-shaped ejector (4) is wide on the upper part and narrow on the lower part. When the water dropping machine for well point is used during construction, ground water is pumped out and consequently the ground water level is lowered. Thus no water can bleed out in the construction area and no water can accumulate, thereby putting an end to collapse accidents. During operation, as the circulating water centrifugal pump can run normally and continuously, the motor can not be damaged.
Description
(1) technical field:
The utility model belongs to the well-points dewatering machine that reduction face of land water level is convenient to foundation construction.
(2) background technology:
In the building operations of low-lying location, underground construction often relates to the underground water of going up, and causes workman's work under bad environment, and constructional difficulties is such as ponding, landslide.Prior art is to extract clear water out with submersible pump, with slush pump water and mud is extracted out in the lump.Because water shortage can make submersible pump and slush pump idle running or change in midair so that frequent burn-out motor causes damage.Underground water is osmosis type gradually in the aquifer, and the water that penetrates continuously can cause landslide, and will to increase labor strength like this influence construction quality and duration.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem of depositing in the background technology, reduces the well-points dewatering machine that face of land water level is convenient to foundation construction and provide.
The invention for solving the technical problem can reach by following technical solution: the driven by motor centrifugal pump inserts cyclic water tank by threeway communication loop water tank, connection " L type " standpipe, ejector, is communicated with ejector with soft suction hose; The drilling well eye is some around the base area construction, and every well is crossed foundation depth deeply and entered the aquifer, and every well is lowered to the screen casing of band filter screen, on ground with header be communicated with each screen casing again with soft pipe connection.
In such scheme, as like bushing pipe being arranged in the ejector of funnel, it is upper coarse and lower fine.
The utility model is compared with background technology has following beneficial effect: the well-points dewatering machine uses in construction, and underground water is drawn out of, groundwater table reduces, and construction area is anhydrous to ooze out, and does not also just have seeping phenomenon, thereby also just can not produce landslide.In the course of the work, owing to there is the cyclic water tank centrifugal pump to run well continuously, motor can scaling loss yet.
(4) description of drawings:
Accompanying drawing 1 is that the well-points dewatering machine operation is installed schematic diagram; Accompanying drawing 2 is Fig. 1 UEJE 4 structure complete section figure.
(5) specific embodiment: below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
In conjunction with shown in Figure 2, motor 1 drives centrifugal pump 2 and inserts cyclic water tanks 3 by threeway 12 communication loop water tanks 3, connection " L type " standpipe 13, ejector 4, is communicated with ejectors 4 with soft suction hose 5 by Fig. 1; The drilling well eye is some around the base area construction, and every well is crossed foundation depth deeply and entered aquifer 11, and every well is lowered to the screen casing 6 of band filter screen 10, is communicated with each screen casing 6 with header 7 and is communicated with flexible pipe 5 on ground 8.In such scheme, 4 li bushing pipe 9 is being arranged as ejector like funnel, it is upper coarse and lower fine.Above-mentioned motor 1 centrifugal pump 2, water tank 3 are mounted on the basis 8.
Claims (2)
1, a kind of well-points dewatering machine that relates to, the soft suction hose (5) that contains motor (1) and the pump (2) that drives and be communicated with is characterized in that:
A, motor (1) drive centrifugal pump (2) and insert cyclic water tank (3) by threeway (12) communication loop water tank (3), connection " L " type standpipe (13), ejector (4), are communicated with ejector (4) with soft suction hose (5);
B, the drilling well eye is some around base area construction, every well is crossed foundation depth deeply and is entered aquifer (11), every well is lowered to the screen casing (6) of band filter screen (10), is communicated with each screen casing (6) with header (7) and is communicated with flexible pipe (5) on ground (8).
2, well-points dewatering machine according to claim 1 is characterized in that: as ejector (4) lining like funnel bushing pipe (9) is being arranged, it is upper coarse and lower fine.
