Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, to specific embodiment, structure, feature and its effect is proposed according to the present invention, detailed description is as follows.
Referring to Figure 1 to Fig. 4, temporary drainage ditch construction method under the conditions of the subgrade of first embodiment of the invention, comprising:
A, according to live gutter design section size or digging machine bucket excavation width, 1 length and width dimensions of prefabricated components are determined.
Prefabricated components 1 include prefabricated panel 1a and prefabricated side plate 1b, prefabricated panel 1a and prefabricated side plate 1b can in-situ precast or factory batch
It measures prefabricated, makes the prefabricated panel 1a and prefabricated side plate 1b, prefabricated panel 1a and the prefabricated side plate 1b of temporary drain respectively
It is respectively equipped with hoisting ring 3；Hoisting ring 3 moves back 100mm in prefabricated panel 1a and the prefabricated every side edge of side plate 1b, and hoisting ring 3 is adopted
It is bent with the hoisting ring 3 of 8mm diameter.
B, excavate temporary drain, stay set drainage grade as required, and clear up substrate and side wall, hoisting prefabricated bottom plate 1a and
Prefabricated side plate 1b,；
C, attachment beam 5 is installed, which connect with the top prefabricated side plate 1b of the two sides prefabricated panel 1a respectively,
The top prefabricated side plate 1b has connection ring 4 corresponding with the attachment beam 5, and connection ring 4 can also be used as lifting and use；
D, using junction, prefabricated panel 1a and the prefabricated panel of cement mortar sealing prefabricated panel 1a and prefabricated side plate 1b
The junction of 1a, prefabricated side plate 1b and prefabricated side plate 1b junction.
Preferred method further includes after step D:
E, the connection for cutting cement mortar, releasing attachment beam 5 and connection ring 4；
F, prefabricated panel 1a and prefabricated side plate 1b is removed in lifting.
It is preferred that step B include: between adjacent prefabricated panel 1a and prefabricated panel 1a or adjacent prefabricated side plate 1b and pre-
There is the lap of splice between side plate 1b processed.
The length of prefabricated panel 1a or prefabricated side plate 1b are between 1.0m~1.5m, and width is between 0.6m~1.0m, in advance
Bottom plate 1a processed or prefabricated side plate 1b with a thickness of between 35mm~45mm, preferred thickness uses 40mm.
The interior of prefabricated panel 1a or prefabricated side plate 1b is equipped with single-layer bidirectional steel mesh 2.Single-layer bidirectional steel mesh 2 is by spacing
The reinforcing bar of 150mm diameter 8mm rearranges in length and breadth.Single-layer bidirectional steel mesh 2 is preferably rearranged using grade III steel in length and breadth.
Connection ring 4 and hoisting ring 3 are welded and fixed with single-layer bidirectional steel mesh 2.Prefabricated panel 1a or prefabricated side plate 1b are by thin
Stone concrete is made.It is preferred that using C20 or more pea gravel concreten.In the present invention, it serial pre-fabrication or factory can manufacture at the scene
Prefabricated panel 1a with the hoisting ring 3 and prefabricated side plate 1b, after excavating temporary drain on-site assembly prefabricated panel 1a with
The prefabricated side plate 1b, without plastering, interval is conserved, and speed of application is fast, and prefabricated panel 1a and the prefabricated side plate 1b be not by software shadow
It rings.
Prefabricated panel 1a of the invention and prefabricated side plate 1b has light weight, thickness thin, and intensity height etc. a little, is not needing
When gutter, it can directly be hung, be reused by hoisting ring 3.More save material in gutter more brick than tradition.
Under the conditions of subgrade, southern summer, rainy season can Quick drainage using the present invention.The present invention is in settlement of foundation
Afterwards, ditch body deforms, and passes through hoisting prefabricated bottom plate 1a and prefabricated side plate 1b；Temporary drain can be repaired, maintenance cost is low.
Under the conditions of subgrade, after gutter is excavated, it is laid with bottom and side wall with this component in time, bottom plate and side plate use
Cement mortar sits slurry connection, prevents wall deformation from caving in, and substrate is soaked to wait adverse effect.Bottom plate is identical as component used in side wall,
Adjacent panels overlap 100mm when laying, guarantee that, when gutter bottom or side wall deform, ditch body is still able to maintain completely.Side
The soil body tilts 10~20 degree to plate outward, then fixed with attachment beam 5.
This component uses C20 or more concrete grade, interior to match 8@of φ, 150 single-layer bidirectional reinforcing bar, and 100mm setting is moved back in edge
Two 8 reinforcing bar hoisting rings 3 of φ, intensity and rigidity of above design based on 1, guarantee material, because of the moisture absorption of GRC concrete
Property, so the present invention is prefabricated using normal concrete；2,100mm setting hoisting ring 3 is moved back in edge, and for a, sedimentation and deformation occurs
When needing to modify gutter, convenient in carrying；B, it is used as inner support positioning and fixing；C, it is positioned when as side plate with bottom plate assembly
And it is fixed use, do not allow in side plate and move or sidesway；D, in the case where no outside soil body can be with fixed side panel, hoisting ring 3 can be made
For binding and fixing use, fixed point is beaten in draining furrow rim, with iron wire and 3 drawknot of hoisting ring, 3 drawknot of opposite hoisting ring of inside two.
3, bottom plate and side plate are sat slurry using cement mortar and are connected, and can guarantee the overall stiffness in gutter, and guarantee that gutter is water-tight.
More than, it is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, although this
Invention has been disclosed in a preferred embodiment above, and however, it is not intended to limit the invention, any person skilled in the art,
It does not depart within the scope of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent
The equivalent embodiment of variation, but without departing from the technical solutions of the present invention, according to the technical essence of the invention to the above reality
Any simple modification, equivalent variations and modification made by example are applied, all of which are still within the scope of the technical scheme of the invention.
