Abstract
The utility model belongs to the technical field of the precast concrete building materials, the utility model relates to a precast concrete prevention of seepage fang han, including interior rack, the culvert body built -in fitting, tongue -and -groove and tongue -and -groove sealing member, wherein, interior rack is imbedded in the concrete culvert wall, it together imbeds in the culvert wall to contain body built -in fitting and interior rack to expose the working face containing the wall surface, contain the tongue -and -groove and be three bench inclination tongue -and -grooves the side, and the both ends outer fringe is contained on its unsmooth two sides side of lieing in respectively, design after the rank amalgamation of tongue -and -groove corrugated surface second and leaves a blank, the interior packing chance water swellable of should the leaving a blank thing that blocks water, contain the tongue -and -groove angle and be the chamfer for fillet, interior angle the side, is provided with between interior angle and tongue -and -groove and tightens up the cable hole, and it is tight that the cable hole is passed with the steel wire hawser when the installation, the utility model relates to a precast concrete prevention of seepage fang han's beneficial effect: solved the contradiction between square culvert leakproofness and the fastening, obtained excellent sealed prevention of seepage effect when guaranteeing to connect fixed quality to the built -in fitting replaces drilling processing, has improved culvert pipe intensity.
Description
Technical field:
The utility model belongs to precast concrete building materials technology field.
Technical background:
In urban planning, underground pipeline layout is a great problem, after correlation technique evolution experience pipeline direct-burried, cast in situs culvert pipe, start the assembled laying technology of universal precast concrete culvert pipe, in this technology, the designing and manufacturing level of concrete prefabricated culvert pipe and installation technology are the keys determining For Underground Culvert laying quality.
Existing precast concrete culvert pipe tongue and groove connection sealing and fastening on there are some contradictions being difficult to be in harmonious proportion: when using conventional seals bar to seal, because tongue and groove machining accuracy problem sealing effectiveness is poor; Use when having a weather strip of water-swellable character, the weather strip of expansion can affect the tight type that tongue and groove connects; As used seal strip groove to retrain the expansion direction of weather strip, then in installation process concavo-convex tongue and groove can damage weather strip work plane to stranding.
Culvert pipe surfaces externally and internally needs out working hole for lifting or installs internal unit, and usual processing method is holed on finished product culvert pipe, easily causes culvert pipe wall crackle, affect product quality and construction quality in process.
Summary of the invention:
Goal of the invention is contained in a kind of forecasting concrete anti-leaking side of the utility model: provide a kind of concrete earthwork that simultaneously can meet connection sealing and compactness to contain design, and substitute Drilling operation with built-in fitting form, improve Total Product quality.
A kind of forecasting concrete anti-leaking Fang Han having built-in fitting of the utility model, comprises interior rack, culvert body built-in fitting, tongue and groove and tongue and groove seal; Wherein, interior rack Transducers Embedded in Concrete is contained in wall; Culvert body built-in fitting and interior rack are together imbedded and are contained in wall, and expose work plane at culvert wall surface; It is three stage inclination angle tongue and grooves that tongue and groove is contained in side, and two ends outer rim is contained in its concavo-convex two sides side of laying respectively at, and is designed with and leaves a blank, the water-blocking material of this interior filling water-swellable of leaving a blank after the split of tongue and groove male and fomale(M&F) second-order; It is fillet that tongue and groove angle is contained in side, and interior angle is chamfering, is provided with and tightens up cable hole between interior angle and tongue and groove, and cable hole is passed with flexible steel wire when mounted and fastened.
Preferably, interior rack adopts reinforcing bar double-layer frame structure.
The hanger installing hole that inwall exposes is contained in the hole for hoist that the built-in fitting side of being included in culvert outer wall exposes and side.Above-mentioned hanger installing hole is for installing hanger or other equipment in the interior hanger of tube bank, cable.
The beneficial effect of a kind of forecasting concrete anti-leaking of the utility model Fang Han: the side of solving contain sealing and fastening between contradiction, excellent sealing anti-seepage effect is achieved while ensureing to be connected and fixed quality, substitute Drilling operation with built-in fitting simultaneously, improve culvert pipe intensity.
Accompanying drawing illustrates:
Fig. 1 is that specific embodiment structural representation is contained in a kind of forecasting concrete anti-leaking side of the utility model;
Fig. 2 is that specific embodiment tongue and groove partial structurtes schematic diagram is contained in a kind of forecasting concrete anti-leaking side of the utility model;
In figure, tongue and groove 1, tongue and groove seal 2, hole for hoist built-in fitting 3, hanger installing hole built-in fitting 4, tighten up cable hole 5.
Detailed description of the invention:
A kind of forecasting concrete anti-leaking Fang Han, comprises interior rack, culvert body built-in fitting, tongue and groove 1 and tongue and groove seal 2; Wherein, interior rack is reinforcing bar double-layer frame, and Transducers Embedded in Concrete is contained in wall; Hole for hoist built-in fitting 3 and hanger installing hole built-in fitting 4 are together imbedded with interior rack and are contained in wall, and expose work plane at culvert wall surface; In tube bank, in hanger, cable, hanger or other equipment are arranged on hanger installing hole 4; It is three stage inclination angle tongue and grooves 1 that tongue and groove 1 is contained in side, and two ends outer rim is contained in its concavo-convex two sides side of laying respectively at, and is designed with and leaves a blank, the tongue and groove seal of this interior filling water-swellable of leaving a blank after the split of tongue and groove male and fomale(M&F) second-order; It is fillet that tongue and groove 1 jiao is contained in side, and interior angle is chamfering, is provided with and tightens up cable hole 5 between interior angle and tongue and groove 1.
During installation, the culvert pipe connected in turn is fastened through tightening up cable hole 5 by flexible steel wire, practical function.
