Description
Technical field
Underground construction dewatering device is the utility model is related to, more particularly to a kind of precipitation well construction.
Background technology
In building foundation pit work progress, because foundation ditch constantly extends to underground, the underground water in water-bearing layer, which returns, pours in base
Hole, cause water burst, gush the husky or prominent accident such as gush.In order to prevent the generation of accident, precipitation operation often is carried out to foundation ditch, i.e., in base
The multiple dewatering well lowerings of watertable of arrangement in hole.Traditional construction method is used without sand drain pipe as dewatering well borehole wall material
Material, water body is filtered by the water penetration filtrate filled on the outside of the borehole wall between the soil body.Because the intensity without sand drain pipe is very low,
In dewatering construction is carried out, the drinking-water pipe of suction pump is stretched into downcast well pipe, and drinking-water pipe is constantly swung, and easily downcast well pipe is touched
It is bad, so that soil enters dewatering well, dewatering well and suction pump are silted up, cause dewatering well and suction pump to scrap, it has to weight
Dewatering well newly is set, great trouble is brought to construction.
Authorization Notice No. is that CN202247918U Chinese utility model discloses a kind of downcast well pipe, including by pvc pipe
Manufactured inner tube, inner tube periphery and water inlet set steel wire, install outer tube outside inner tube, steel wire between the inner and outer pipe sections,
Outer tube is used without sandpipe.Dewatering well tubing in the market is as the material of the downcast well pipe, mainly using pvc pipe, but
Pvc pipe intensity is relatively low, is easily destroyed in work progress.
Utility model content
The purpose of this utility model is to provide a kind of precipitation well construction so that the intensity of dewatering well is guaranteed, and improves
Dewatering effect.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of precipitation well construction, including
Well, the hypomere ecto-entad of well are sequentially provided with galvanized wire filter screen, twine silk, pad muscle, PPR water pipe, galvanized wire filter screen
Mesh number is 60 ~ 100 mesh, and PPR water pipe side wall is provided with permeable hole, is filled with mineral granule between PPR water pipe and pad muscle, in well epimere
Cohesive soil is filled between wall and PPR water pipe, PPR water pipe bottom is provided with sealing part.
By using above-mentioned technical proposal, pvc pipe is replaced with the PPR pipe of high intensity, to strengthen the intensity of water pipe, makes it not
It is fragile, extend the service life of dewatering well；Simultaneously on the one hand galvanized wire filter screen can play a role in filtering, the corrosion-resistant, longevity
Life length, the structural strength of dewatering well on the other hand can also be improved as intermediate.Such a precipitation well construction, structural strength is high, together
When there is preferable water penetration and anti-bottom permeability performance.
Preferably, the outer wall of PPR water pipe is provided with along its circumferential equally distributed vertical reinforced.
By using above-mentioned technical proposal, vertical reinforced is set in the outer wall of PPR water pipe, on the one hand can strengthen water pipe
Intensity, reduces its impaired probability, on the other hand can play the vertical guide functions to current, improves dewatering effect.
Preferably, sealing part is steel plate for sealing water.
By using above-mentioned technical proposal, sealing part plays a part of sealing PPR pipe bottom, in case PPR pipe bottom intakes
Bring impurity particle into and block water pipe, influence the service life of dewatering well；Steel plate for sealing water is simple and convenient as sealing part, while steel
Plate good corrosion resistance.
Preferably, steel plate for sealing water is provided with the neck of annular, and neck agrees with PPR water pipe.
By using above-mentioned technical proposal, annular slot is set to fix PPR water to a certain extent on steel plate for sealing water
Pipe, PPR water pipe, which is connected in neck, is not susceptible to relative motion, therefore sealing improves.
Preferably, the both sides of neck are provided with spacing rib.
By using above-mentioned technical proposal, spacing rib is added in the both sides of neck, can further be improved to PPR water pipe
Spacing fixation, reduce the possibility of infiltration.
Preferably, jacket pipe untill sealing part, water-baffling sleeve pipe sleeve be located at PPR water pipe bottom and the mouth of pipe upward, PPR water pipe
The mouth of pipe is enclosed with two layers of gauze, and gauze is wrapped with two layers of nylon net cloth, and gauze is folded in PPR water pipe and sealing with nylon net cloth
Between sleeve pipe.
By using above-mentioned technical proposal, sealing part uses sealing sleeve pipe, and sealing is high and simple in construction, can quickly pacify
Assembly and disassembly are unloaded；Gauze and nylon net cloth are set between PPR water pipe and sealing sleeve pipe, in order to avoid during the sealing function forfeiture of sealing sleeve pipe,
The large particulate matters such as silt enter in PPR water pipe, and PPR water pipe is blocked.
Preferably, the mesh number of gauze is 120 mesh, and the mesh number of nylon net cloth is 80 mesh.
By using above-mentioned technical proposal, the effect of gauze and nylon net cloth is after sealing casing damage cracking two
Person can play a part of filtering large particulate matter, in case bulky grain enters oral siphon and blocked.
