Abstract
The utility model relates to an auxiliary device for water drainage of a deep foundation pit, which comprises a reinforcing cage, a screen mesh and a cross beam, wherein the reinforcing cage is in a cylinder structure of which the top is opened, the screen mesh is arranged on the surface of the reinforcing cage, the cross beam is arranged at the top of the reinforcing cage, and the reinforcing cage and the cross beam are made of steel bars. Compared with the prior art, the device provided by the utility model has a simple structure, is convenient to use, can enable the water drainage operation of the deep foundation pit to be carried out smoothly and safely, has low cost and is simple and convenient to manufacture, thereby ensuring the operation safety of the deep foundation pit and improving the working efficiency.
Description
Technical field
The utility model relates to the realm of building construction, particularly is used for the servicing unit of deep foundation ditch draining.
Background technology
In the work progress of deep foundation ditch, whether the deep foundation ditch draining is smooth and easy is the essential condition that guarantees deep foundation ditch safety, and according to the job specfication requirement, groundwater table must drop under the substrate more than the 500mm in the deep foundation ditch.Traditional deep foundation ditch internal drainage job practices is that a sump that is deeper than about substrate 1m is dug in the appropriate location in foundation ditch, and spreading thickness in the bottom of sump is the gravel about 100mm, then submersible pump is put into sump and carries out central drainage.Because deep foundation ditch underground construction amount is bigger, long construction period, sump is easy to cave in through long period of soaking, buries submersible pump, causes basic underground water not discharge smoothly, and the safe construction of deep foundation ditch is difficult to guarantee.
Therefore, the draining of deep foundation ditch needs a kind of cost low, simple in structure, easy to use, can be smooth and easy, the servicing unit of safe draining.
Summary of the invention
The purpose of the utility model provides deep foundation ditch draining servicing unit, and this apparatus structure is simple, easy to use, can make smooth and easy, safe the carrying out of draining of deep foundation ditch, and with low cost, simple for production.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
Deep foundation ditch draining servicing unit comprises reinforcing cage, screen cloth, crossbeam, and described reinforcing cage is the cylindrical structure of top end opening, and the surface of reinforcing cage is provided with screen cloth; The top is provided with crossbeam.
Described reinforcing cage and crossbeam all adopt reinforcing bar to process.
Compared with prior art; The utility model has the advantages that: this apparatus structure is simple, easy to use, can make smooth and easy, safe the carrying out of draining of deep foundation ditch, and with low cost, simple for production; And then guaranteed the safety of deep foundation ditch operation to have improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic top plan view of the utility model.
Among the figure: the 2-reinforcing cage 3-crossbeam 4-nylon rope 5-screen cloth 6-gutter 7-gravel 8-water pump of 1-deep foundation ditch bottom surface
The specific embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
See Fig. 1, Fig. 2, deep foundation ditch draining servicing unit comprises reinforcing cage 2, screen cloth 5, crossbeam 3, and described reinforcing cage 2 is the cylindrical structure of top end opening, and the surface of reinforcing cage 2 is provided with screen cloth 5; The top is provided with crossbeam 3, and reinforcing cage 2 all adopts reinforcing bar to process with crossbeam 3.
The method for using of this device is: after deep foundation ditch dug, a sump that is deeper than deep foundation ditch bottom surface 1 was dug in the appropriate location in deep foundation ditch, and the sump bottom is adopted and completely spread greater than the thick gravel of 100mm; Vertically be installed to manufactured reinforcing cage 2 in the sump again; Closely knit around the reinforcing cage in the sump with gravel 7 even backfills, adopt nylon rope 4 to be hung on the crossbeam 3 on reinforcing cage 2 tops on submersible pump 8, adjust the distance of submersible pump 8 apart from the bottom surface; Water in the sump just can be discharged from gutter 6 smoothly; Guaranteed that the operation of deep foundation ditch internal drainage is smooth and easy, and effectively prevented the cave-in accident generation, safe and reliable.
