Description
Technical field
the utility model relates to a kind of draining side device, particularly relates to a kind of deep foundation ditch french drain collecting well and falls dewatering installation, belongs to the construction drainage technical field.
Background technology
along with domestic each metropolis building density is increasing, each new building periphery all round all kinds ofly build, structure.New building construction period can supply to utilize site area also more and more littler, then large quantities of building foundation pit supporting all by there being the angle supporting to change vertical supporting into, foundation ditch retaining wall and outer wall of basement vertical distance are more and more littler.All below the groundwater table of place, during outer wall of basement and basement bottom board and the bearing platform construction, deep foundation ditch french drain collecting well falls most of basement bottom board absolute altitudes, drainage has become an important engineering measure during the deep foundation pit construction.
Summary of the invention
The purpose of
the utility model is; Provide a kind of do not need the later stage remove, fall draining economy, convenience and practical, also can effectively reduce the ater-casting cleaning and base plate early stage anti-floating pressure deep foundation ditch french drain collecting well dewatering installation falls, thereby overcome the deficiency of prior art.
The technical scheme of
the utility model: dewatering installation falls in a kind of deep foundation ditch french drain collecting well of the utility model, comprises being located between outer wall of basement and the pattern foundation pit supporting structure catchwater is set, and is provided with the french drain pipe below the catchwater; Comprise being located at and the french drain pipe is set below the inboard base plate of outer wall of basement; Be provided with the french drain pipe of french drain pipe below the inboard base plate of outer wall of basement below the catchwater and be communicated with, the french drain pipe inboard at outer wall of basement is provided with interim collecting well with the position that overlaps of basement post-pouring zone; On basement post-pouring zone, be provided with more than one spilled water hole.
In
aforementioned means, said french drain pipe comprises the gutter that is located in the trench, and gutter is provided with the infiltration hole; The gutter bottom is provided with rubble packed layer, fine-stone concrete bed course and back fill course from top to bottom successively; The gutter top is provided with rubble packed layer, geotextiles separation layer and fine-stone concrete bed course from the bottom to top successively.
compared with prior art, the utility model construction is simple, moulding is quick.In effective dewatering; The actual conditions that the basement periphery can't dewatering construction have also been solved; And solved the work that draining falls in later stage unnecessary water body to a great extent; Be convenient to the construction of outer wall of basement ater-casting, solved the problem that traditional handicraft ater-casting construction ponding can't be handled.Realize base plate cushion construction in advance, avoided the various matching program work holdup phenomenons that cause the multiple operation intersection to bring because of simultaneous construction.The difficulty of construction of basement bottom board reduces; The engineering time of base plate is shortened dramatically, saved construction and construction cost, what is more important; Guaranteed the safety of foundation ditch retaining wall; The shortening in basement construction cycle when guaranteeing whole foundation ditch safety, has also guaranteed neighboring buildings and safety of environment.
