Abstract
Pipeline excavates groove well-points dewatering device, it is mainly used for pipeline and excavates the sedimentation of groove water level, it includes suction pump, it is characterized in that suction pump connects water main, water main is connected with some vertical drinking-water pipes, the water inlet of vertical drinking-water pipe is equipped with filter screen, and vertical drinking-water pipe is inserted into underground and positioned at the lower section of ground groove.The water level on groove periphery quickly can be down to beneath trenches by the utility model, not only increased pipeline and excavated groove construction speed, and improve the construction operation environment of worker.
Description
Technical field
The utility model is mainly used for pipeline and excavates the sedimentation of groove water level, and in particular to pipeline excavates groove well-points dewatering dress
Put.
Background technology
During municipal administration, chemical building or installation, buried pipeline such as runs into level of ground water height and is sand grains soil again
The place that matter and big machinery construction equipment can not construct, can bring very big difficulty to construction enterprises.
Such as：The Yantai east line being responsible for undertaking the construction of by Zhong Huaerjian groups, western line steam pipe network engineering, total length 10Km, due to
It is municipal works, engineering starting point is Yantai Power Plant, and power plant is coastal cities, Urban Landform or mound just in city
Mound hill features, underground water are more.
When pipeline buries progress channel excavation construction, the sandy soil on groove both sides are easily toward flowing down, and groove internal water accumulation is deeper, nothing
Method carries out excavation construction.
The content of the invention
In order to which the water level on grooving periphery is down to beneath trenches, to facilitate channel excavation to construct, this practicality is new
Type provides well-points dewatering device.
Pipeline excavates groove well-points dewatering device, including suction pump, it is characterized in that suction pump connects water main, water main connects
Some vertical drinking-water pipes are connected to, the water inlet of vertical drinking-water pipe is equipped with filter screen, and vertical drinking-water pipe is inserted into underground and positioned at ground
The lower section of groove.
Connected between water main and vertical drinking-water pipe by bent union, bent union is L-shaped pipe, and bent union is equipped with valve.
The application method of the utility model：Vertical drinking-water pipe is inserted into underground, starts suction pump, passes through water in well casing
Vertical drinking-water pipe is pumped into water main and is discharged at a distance by suction pump；Suction pump speed of drawing water is more than recharge of ground water speed, ground
Level of ground water can be reduced to below bottom of trench absolute altitude around groove, pipe trench both sides is in anhydrous state, in order to construction into
OK.
The water level on groove periphery quickly can be down to beneath trenches by the utility model, not only increased pipeline and excavated groove
Construction speed, and improve the construction operation environment of worker.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
1st, suction pump, 2, water main, 3, drinking-water pipe, 4, filter screen, 5, bent union, 6, valve, 7, trench trough rim line.
Embodiment
Shown in Fig. 1, pipeline excavates groove well-points dewatering device, including suction pump 1, it is characterized in that suction pump 1 connects main water
Pipe 2, water main 2 are connected with some vertical drinking-water pipes 3, and the water inlet of vertical drinking-water pipe is equipped with filter screen 4, vertical drinking-water pipe insertion
To underground and positioned at the lower section of ground groove.
Connected between water main 2 and vertical drinking-water pipe 3 by bent union 5, bent union 5 is L-shaped pipe, and bent union 5 is equipped with
Valve 6.
Water main 2 bends to U-shaped, the two ends sealing of water main 2.
The U-shaped bottom position of water main 2 is connected with 3 drinking-water pipes, and two edge positions are respectively connected with 4 drinking-water pipes.
The caliber of water main 2 is 120mm, and the caliber of drinking-water pipe 3 is 25mm ~ 50mm.
Explanation：The filter screen of the utility model can be replaced by chimney filter.
