Abstract
The utility model discloses a semicircular drainage ditch for a building foundation pit. The semicircular drainage ditch comprises a plain concrete layer formed in the ground, wherein at least one semicircular drainage pipe is arranged in the plain concrete layer; the outer side of the drainage pipe is tightly combined with the plain concrete layer; the diameter of the drainage pipe is 100-400 millimeters; adjacent drainage pipes are overlapped in sequence into a whole; both sides of each drainage pipe are coated with the plain concrete layer. By adopting the semicircular drainage pipes in the technical scheme, sundry internal corners are eliminated. The semicircular drainage ditch is simple in structure and low in manufacturing cost, water is drained effectively, and the drainage smoothness can be ensured.
Description
Technical field
The utility model relates to construction foundation working field, is specifically related to a kind of building foundation pit and uses semicircle gutter.
Background technology
When foundation pit construction, for effective draining, tend to arrange gutter inside and outside foundation ditch, organized by the water discharge in foundation ditch, prevent from cheating outer water simultaneously and flow in hole.Conventionally gutter adopts the brick gutter of rectangle, but brick gutter conventionally will pass through the steps such as foundation pad, gutter two brick on edge, brick surface brush cement mortar and just can complete, and construction bothers, and after falling into foreign material in gutter, difficulty is swept.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of building foundation pit simple and reasonable for structure to use semicircle gutter, can effectively solve and in gutter, fall into that inner corner trim difficulty after foreign material is swept, brick gutter cost is high and the problem of construction trouble, and draining effectively, the patency of assurance draining.
For achieving the above object, the utility model provides following technical scheme: a kind of building foundation pit is used semicircle gutter, comprise the plain concrete layer being arranged in ground, in described plain concrete layer, be at least provided with a semicircular gutter, combine closely with plain concrete layer in described gutter outside, the diameter of described gutter is 100mm-400mm, and it is in aggregates that adjacent drainage channel pipe overlaps structure successively, and wrap up by plain concrete layer every gutter both sides.
By adopting technique scheme, adopt semicircular gutter no-sundries inner corner trim, simple in structure, low cost of manufacture, and draining effectively, can guarantee the patency of draining.
The utility model is further set to: on the plain concrete layer near the gutter left and right sides, be provided with draw-in groove, described gutter top is provided with screen pack, the edge downward bending of this screen pack, and bending edges and draw-in groove clamping.By this setting, can filter the foreign material that volume is larger, make gutter draining patency better.
The utility model is also further set to: the ground of the described gutter left and right sides faces the downward-sloping setting of gutter, and the gradient is 0.5%.By this setting, drainage works is more reliable.
The utility model is also further set to: described gutter is hard PVC pipe or bellows.By this setting, drain structure is simple, and cost is low, easy for installation.
The utility model is further set to: described plain concrete layer longitudinal section is inverted trapezoidal structure.By this setting, the utility model work is more reliable.
Below in conjunction with specification drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the enlarged drawing of I portion in Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of building foundation pit that the utility model provides is used semicircle gutter, comprise the plain concrete layer 2 being arranged in ground 1, in described plain concrete layer 2, be at least provided with a semicircular gutter 3, described gutter 3 outsides and plain concrete layer 2 are combined closely, the diameter of described gutter 3 is 100mm-400mm, and it is in aggregates that adjacent drainage channel pipe 3 overlaps structure successively, and wrap up by plain concrete layer 2 every gutter 3 both sides.On plain concrete layer 2 near gutter 3 left and right sides, be provided with draw-in groove 21, described gutter 3 tops are provided with screen pack 4, the edge downward bending of this screen pack 4, and bending edges and draw-in groove 21 clampings.
For making the utility model draining more smooth and easy, as preferably, the ground of gutter 3 left and right sides faces the downward-sloping setting of gutter 3 described in the present embodiment, and the gradient is 0.5%.
Described gutter 3 is plastic pipe, can adopt hard PVC pipe, bellows etc., and 3 of adjacent drainage channel pipes adopt concrete to wrap, with anti-seep water.
Described plain concrete layer 2 longitudinal section are inverted trapezoidal structure.
The utility model adopts semicircular gutter 3 drainings, and gutter 3 size design are reasonable, gutter 3 gap is around filled full by plain concrete, adopt semicircular gutter 3 no-sundries inner corner trims, simple in structure, low cost of manufacture, and draining effectively, can guarantee the patency of draining.
Above-described embodiment is to specific descriptions of the present utility model; only for the utility model is further described; can not be interpreted as the restriction to the utility model protection domain, the technician of this area according to the content of above-mentioned utility model to the utility model make some nonessential improvement and adjust all fall into protection domain of the present utility model within.
