Abstract
The utility model discloses a kind of pipe well well-points dewatering and transfer the device of sand concrete free pipe, it comprises wooden round tray, pallet thickness is 30mm-50mm, pallet diameter is identical with sand concrete free pipe diameter, in center line both sides, the bottom surface of pallet, a batten is respectively set, batten height is greater than wirerope diameter, and the spacing between two battens is greater than wirerope diameter.Adopt this device simple to operate, due to can be prefabricated in advance, simple installation, improves pipe well well-points dewatering and transfers the deficiency of sand concrete free Manifold technology, saves material and the energy, and cost saving, shortens the construction period.
Description
Technical field
The utility model relates to dewatering well and places sand-free concrete tube device.
Background technology
Along with the large-scale development construction of Chinese society market economy, the construction scope expanding day of the each department of our country, base pit engineering also becomes the important composition content of construction work, makes its development more and more extensively with more deep.In each large-engineering and all kinds of ground, basis, foundation pit construction all need to reduce underground water, the safety of guarantee foundation pit construction and high efficiency.Pipe well well-points dewatering technology is exactly to arrange well point around at foundation ditch, and then the work of drawing water in well, thereby the groundwater table in reduction foundation ditch, effectively prevent that the present situation that drift sand, piping and bottom heave lost efficacy from appearring in foundation ditch, be conducive to create solely thick condition for foundation pit construction, increase work efficiency.
Current common employing device is to place without sandpipe by hoist engine, and cost is high, operating condition is restricted.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of and can economize on resources, saves the duration, can be mass, and the device of sand concrete free pipe is transferred in pipe well well-points dewatering easy and simple to handle.
In order to achieve the above object, the technical solution adopted in the utility model is:
The device of sand concrete free pipe is transferred in a kind of pipe well well-points dewatering of the present utility model, it comprises wooden round tray, pallet thickness is 30mm-50mm, pallet diameter is identical with sand concrete free pipe diameter, in center line both sides, the bottom surface of pallet, a batten is respectively set, batten height is greater than wirerope diameter, and the spacing between two battens is greater than wirerope diameter.
The beneficial effects of the utility model are: simple to operate.Due to can be prefabricated in advance, simple installation, improves pipe well well-points dewatering and transfers the deficiency of sand concrete free Manifold technology, saves material and the energy, and cost saving, shortens the construction period.
Accompanying drawing explanation
Fig. 1 is the plan view that the device of sand concrete free pipe is transferred in a kind of pipe well well-points dewatering of the present utility model;
Fig. 2 is the sectional drawing of the device shown in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
The device of sand concrete free pipe is transferred in a kind of pipe well well-points dewatering of the present utility model as shown in drawings, it comprises wooden round tray 1, pallet thickness h is 30mm-50mm, pallet diameter d is identical with sand concrete free pipe diameter, in center line both sides, the bottom surface of pallet, a batten 2 is respectively set, batten height is greater than wirerope diameter, and the spacing between two battens is greater than wirerope diameter.
The installation and application of this device is:
Step 1: after dewatering well pore-forming, at wellhole place, place and be with four steel pipes the job platform that # font welds together, again by the slideway between two battens of the pallet in steel wire penetrating the utility model device, wire rope two ends are wound around on job platform steel pipe, can reduce like this power being produced by the deadweight of sand concrete free pipe, every end will have a workman to hold wire rope, one people holds pallet, and then on pallet, place first segment sand concrete free pipe, first segment sand concrete free pipe and pallet are fixed, can be avoided so lower pipe process pallet slippage and conversely;
Step 2: transfer wire rope, sand concrete free pipe falls with pallet, treats that first segment sand concrete free pipe roof fall, to exceeding wellhole 300mm, places the second pipe joint on the first pipe joint, according to step 1, transfers the second pipe joint, and so circulation, until sand concrete free pipe is covered with in dewatering well.
