compared with prior art, indoor drainage open drain of the present invention by water string through indoor leak detection pipe trench furrow bank be located at the gutter of hunting leak in pipe trench and be connected, leak detection pipe trench is provided with cover plate, cover plate top earthing, well solves the draining in indoor drainage open drain and antifreeze problem.Both met the requirement of " Code for building construction in collapsible loess zone ", gutter also can be avoided to block because freezing, and the entrance of gutter is provided with grid screen, solves the foreign material blocking drainage pipe in the ditch of open drain.It is simple that the present invention not only has structure, advantage easy for installation, and design ingenious, safe and reliable, practical, the advantages such as convenience of drawing materials.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
being labeled as in accompanying drawing: 1-indoor drainage open drain, the indoor leak detection pipe trench of 2-, the furrow bank of the indoor leak detection pipe trench of 3-, 4-building foundation, the outdoor leak detection pipe trench of 5-, 6-gutter, 7-water string, 8-grid screen.
Detailed description of the invention
below in conjunction with accompanying drawing, the present invention is described in further detail, but not as any limitation of the invention.
the water discharge method in indoor drainage open drain, Collapsible Loess District, as shown in Figure 1.The method utilizes the leak detection pipe trench of existing passing through building foundation bottom by outside the water discharge chamber in indoor drainage open drain; Specific practice is: be located at by the indoor drainage open drain port of export outside the furrow bank of existing indoor leak detection pipe trench, and a gutter is set up in existing leak detection pipe trench, then indoor leak detection pipe trench furrow bank on open the circular hole that a bore is greater than gutter external diameter, embedded section water string in circular hole, gutter from water string through stretching into indoor drainage open drain; Water in indoor drainage open drain drains into the catch pit away from building by gutter.Circular hole on indoor leak detection pipe trench furrow bank is positioned at the bottom in indoor drainage open drain, and the bottom of trench in the water string on circular hole and indoor drainage open drain is tangent; So that the water in indoor drainage open drain flows into outside gutter discharge chamber smoothly.The water inlet of gutter to be provided with in grid screen interception indoor drainage open drain foreign material with anti-blocking drain pipe.
discharge structure according to the indoor drainage open drain, of the present invention a kind of Collapsible Loess District of said method formation is that as shown in Figure 1, this structure comprises existing indoor leak detection pipe trench 2 and outdoor leak detection pipe trench 5 to the schematic diagram of this structure; It is characterized in that: have indoor drainage open drain 1 at furrow bank 3 peripheral hardware of indoor leak detection pipe trench, the indoor leak detection pipe trench furrow bank 3 of end, indoor drainage open drain 1 is provided with circular hole, is provided with gutter 6 in circular hole, and gutter 6 cylindrical is tightly connected through water string 7 and circular hole.Circular hole on indoor leak detection pipe trench furrow bank 3 is positioned at the bottom in indoor drainage open drain 1, and the water string 7 on circular hole is tangent with the bottom of trench in indoor drainage open drain 1.The water inlet of gutter 6 is provided with grid screen 8.The leak detection pipe trench that indoor leak detection pipe trench 2 and outdoor leak detection pipe trench 5 are formed passes through building foundation 4 and extends to outdoor, and gutter 6 is arranged along leak detection pipe trench.
embodiment:
when carrying out the design in indoor drainage open drain 1, indoor drainage open drain 1 being located at outside existing indoor leak detection pipe trench furrow bank 3, then in existing indoor leak detection pipe trench 2 and outdoor leak detection pipe trench 5, laying a gutter 6.Then on indoor leak detection pipe trench furrow bank 3, open a circular hole, pre-embedded water-proof sleeve tube 7 on circular hole, water string 7 is made with flexible waterproof material, and water proof rubber can be adopted to make.Water string 7 on circular hole is tangent with the bottom of trench in indoor drainage open drain 1.After the concrete consolidation of pre-embedded water-proof sleeve tube, the mouth of pipe of gutter 6 is stretched into indoor drainage open drain 1 by water string 7, the water in indoor drainage open drain 1 drains into outdoor catch pit by gutter 6.
above-mentioned indoor leak detection pipe trench 2 and outdoor leak detection pipe trench 5 are a part for existing leak detection pipe trench, existing leak detection pipe trench passes through building foundation 4 and is connected with outdoor, the water supply and sewerage pipeline (not shown in FIG.) of whole building building is equipped with in leak detection pipe trench, the present invention be set up in existing leak detection pipe trench one aim at indoor drainage open drain 1 arrange gutter 6, gutter 6 when not affecting existing supplying drainage by leak detection pipe trench move towards arrange.The emphasis of construction is the sealing carrying out gutter 6 mouth of pipe place, prevents the water in indoor drainage open drain 1 from flowing into leak detection pipe trench.In order to prevent gutter 6 from resulting in blockage, be provided with grid screen 8 at gutter 6, grid screen adopts φ 5 reinforcing bar to be welded on the mouth of pipe by spacing 15mm, to tackle in indoor drainage open drain foreign material with anti-blocking drain pipe by grid screen 8.Existing leak detection pipe trench comprises indoor leak detection pipe trench 2 and outdoor leak detection pipe trench 5, and indoor leak detection pipe trench 2 and outdoor leak detection pipe trench 5 are equipped with cover plate, and outdoor cover plate is covered with a thick layer of loess.Because gutter 6 is entered underground by deep, when cold weather, the water in gutter 6 can not be frozen.The present invention well solves the drainage problem in indoor drainage open drain.Both met the requirement of " Code for building construction in collapsible loess zone ", gutter also can be avoided to block because freezing, and the entrance of gutter is provided with grid screen, solves the foreign material blocking drainage pipe in the ditch of open drain.It is simple that the present invention not only has structure, advantage easy for installation, and design ingenious, safe and reliable, practical, the advantages such as convenience of drawing materials.
