Abstract
The invention discloses a plugging structure. The plugging structure comprises a cement sand-free pipe, wherein a steel sleeve is arranged on the cement sand-free pipe; the steel sleeve is positioned on the middle part of the cement sand-free pipe; the top of the steel sleeve is connected with the cement sand-free pipe; the bottom of the steel sleeve is positioned on a cushion; the cushion is hermetically connected with the cement sand-free pipe; the cushion is transversely arranged on the lower surface of the cement sand-free pipe; flanges are arranged on the two side faces of the cushion; the tops of the flanges are clamped on the cushion; a settling mechanism is connected between the two flanges; the settling mechanism is of a convex structure; a settling bolt is arranged on the middle part of the settling mechanism; the top of the settling bolt is fixedly connected with the convex part of the settling mechanism; the bottom of the settling bolt is positioned on a support plate; the two ends of the support plate are fixed on the flanges. The plugging structure is easy to operate, and the construction period is shortened; a plurality of waterproof structures are adopted, so that the waterproofing effect of a concrete bottom plate can be ensured; meanwhile, the influences of external factors such as the depth and size of a basement foundation pit, the magnitude of tube well water inflow and the magnitude of water pressure are eliminated.
Description
Technical field
The present invention relates to a kind of water conservancy shutoff facility, particularly a kind of plugging structure.
Background technology
Along with the fast development in builing industry and city, many highrise buildings are rised sheer from level ground, and the projected depth of Underground Construction is also more and more darker.The different action mode of underground water and the size degree of water pressure, very large inconvenience is brought to Underground Construction, particularly under the operating mode that peripheral water stopping wall water sealing effect is bad, difficulty of construction is larger, it is also proposed higher requirement to the shutoff mode of precipitation pipe well in foundation ditch both effect.Shutoff for pipe well must take different measures according to different situations, can reach and neither affect underground engineering structure concrete quality, again can the object of effective shutoff pipe well.Therefore need a kind of good plugging structure, just can better reach this result of use, its difficulty of construction could not be affected.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provides a kind of simple to operate, shortens the plugging structure of construction period.
To achieve these goals, the technical solution used in the present invention is such: plugging structure of the present invention, comprise cement without sandpipe, cement is provided with steel sleeve without sandpipe, steel sleeve is positioned at cement without in the middle part of sandpipe, steel sleeve top is connected without sandpipe with cement, be positioned on a bed course bottom it, bed course and cement are tightly connected without sandpipe, bed course is horizontally installed on cement without sandpipe soffit, bed course two sides are provided with flange plate, clamping between flange plate top and bed course, sink mechanism is connected with between two flange plates, sink mechanism adopts convex shape, in the middle part of sink mechanism, sedimentation bolt is vertically installed, sedimentation bolt top is fixedly connected with sink mechanism convex portion, be positioned in a gripper shoe bottom it, gripper shoe two ends are fixed on flange plate, also comprise steel plate for sealing water, steel plate for sealing water is arranged through flange plate.
Further, as a kind of concrete form of structure, steel bushing of the present invention is connected by anchor ear without between sandpipe with cement.
Further, as a kind of concrete form of structure, bed course width of the present invention is that cement is without 1/3rd of sandpipe length.
Further, as a kind of concrete form of structure, steel plate for sealing water length of the present invention is equal without the length of sandpipe with cement.
Further, as a kind of concrete form of structure, flange plate of the present invention has several installation through hole.
Further, as a kind of concrete form of structure, more than one of sedimentation bolt of the present invention.
Compared with prior art, the invention has the advantages that: this plugging structure is simple to operate, shorten the construction period, have employed multi layer waterproof construction measure, the waterproof effect of concrete floor can be ensured, simultaneously again not by the impact of the extraneous factors such as the depth of basement foundation ditch and size, pipe well water yield size and water pressure size.
