Abstract
The utility model discloses a water stop device for an opening of a circular open caisson. The water stop device comprises a water stop wall (7) poured on the inner side (13) of a circular open caisson wall (8); the opening (14) is reversed in the middle of the water stop wall (7); the diameter of the reserved opening (14) is greater than the external diameter of a pipeline; an annular steel plate (2) is arranged on the inner side wall of the reserved opening (14); and a tightening device is arranged on the annular steel plate (2). Compared with a water stop device for a square open caisson, the water stop device provided by the utility model has the advantages that a mounting steel loop welded on a pre-buried steel loop is omitted, bolts are directly welded on the pre-buried steel plate, the construction is simple and convenient, and groundwater and silt and sand can be prevented from flowing into the open caisson to ensure the construction safety.
Description
Technical field
The utility model relates to the sealing process field at circular open caisson hole in the jacking construction, particularly a kind of circular open caisson hole antipriming.
Background technology
In the jacking construction process, the hole of slightly larger in diameter in outer diameter tube need be reserved or dig to open caisson, can be smoothly appears or enter the hole received well from open caisson in order to guarantee pipeline.Be lower than under the groundwater table situation at pipeline, as the gap between pipeline and the open caisson not being sealed, underground water and silt particle can flow in the open caisson along this gap, the lighter can influence the operation of active well, can cause near the surface subsidence in hole, tube coupling to sink, even can influence the safety of surrounding buildings thing and pipeline when serious.
The hole measures of preventing water that square reinforced concrete open caisson is provided with is as follows: shift to an earlier date pre-buried doughnut-shaped steel plate at openings position during open caisson manufacture, treat that well sinking arrives design elevation and constructed behind the base plate, welded and installed steel loop on doughnut-shaped steel plate is installed the steel loop center and is consistent with design pipeline center; In that several installation rubber tiles of welding and the required bolt of keeper plate of steel on the steel loop are installed, rubber ring and keeper plate of steel are installed afterwards.Because square calmness is constructional different with circular open caisson, this processing mode is only applicable to the sealing of square active well, is not suitable for circular open caisson.And through retrieving the antipriming of also not finding to be fit to circular open caisson.
In sum, the weak point of present circular open caisson antipriming is not have suitable this type of easy device.
The utility model content
Technical problem to be solved in the utility model provides a kind of circular open caisson hole antipriming, and the sealing of convenient circular open caisson is simple in structure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of circular open caisson hole antipriming, comprise the seepproof screen that is cast in circular caisson wall inboard, reserve the hole in the middle of the described seepproof screen, the slightly larger in diameter at described reservation hole is in the external diameter of pipeline; Described reservation hole inside wall is provided with doughnut-shaped steel plate, and doughnut-shaped steel plate is provided with fastener.
Preferably, described fastener comprises bolt, watertight rubber plate, pressing plate and is used for fastening nut, described watertight rubber plate, pressing plate and be used for fastening nut and be successively set on bolt, multiple sealing and fastening, both guarantee stagnant water effect, increased the steadiness of device again.
Preferably, described watertight rubber plate is an annular, and it comprises canned paragraph and nose section, and described canned paragraph is fixed on the doughnut-shaped steel plate, and described nose section is overlying on to be reserved on the hole, improves stagnant water effect.
Preferably, equidistantly be provided with some bolts on the described doughnut-shaped steel plate, the symmetry of not only attractive in appearance but also assurance device.
Preferably, have on the described pressing plate and be used for along reserving the elongated slot that hole diameter of axle direction moves.
Preferably, described doughnut-shaped steel plate inside wall is provided with some dowels, and the end of described dowel is a hook portion, and described hook portion stretches in the seepproof screen.
Preferably, the plane section of described seepproof screen is shaped as circular arc.
Preferably, the closely knit filling fine-stone concrete in the gap between described duct wall and the service pipe guarantees sealing effectiveness.
Preferably, add concrete and stiffener in the reservation hole of described seepproof screen.
The utility model has following beneficial effect with respect to prior art: the circular antipriming of the utility model provides a kind of antipriming simple in structure that is fit to circular open caisson relatively.The measure of phase square shaped open caisson water stop structure, antipriming of the present utility model has also been cancelled the installation steel loop that is welded on the pre-buried steel loop, bolt directly can be welded on the pre-embedded steel slab, it is simple, convenient to construct, and can effectively stop underground water and silt particle to flow in the open caisson.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Shown in Fig. 1,2 and 5, a kind of circular open caisson hole antipriming comprises the seepproof screen 7 that is cast in circular caisson wall 8 inboards 13.The plane section of seepproof screen 7 is shaped as circular arc, and reserves hole 14 in the middle of this seepproof screen 7.Reserve the external diameter of the diameter at hole 14 greater than pipeline.。Reserve hole 14 inside walls and be provided with ring-like steel plate 2, ring-like steel plate 2 is embedded on the inside wall of reserving hole 14.Be welded with fastener on the doughnut-shaped steel plate 2.Fastener comprises bolt 6, watertight rubber plate 3, pressing plate 4 and is used for fastening nut 5.Watertight rubber plate 3, pressing plate 4 be used for fastening nut 5 and be successively set on bolt 6, multiple sealing and fastening had both guaranteed stagnant water effect, increased the steadiness of device again.Weld bolt 6 on ring-like steel plate 2, bolt 6 is corresponding mutually with the position of rubber tile 3, pressing plate 4, installs successively.After installing rubber tile 3 and pressing plate 4, fastening nut 5.So far, the sealing collar at reservation hole 14 installs.Watertight rubber plate 7 be shaped as annular, it comprises canned paragraph 15 and nose section 16 two parts.Canned paragraph 15 is fixed on the ring-like steel plate 2, and nose section 16 is overlying on reserves on the hole 14, and part hides reserves hole 14, improves stagnant water effect.Also equidistantly be welded with some bolts 6 on the doughnut-shaped steel plate 2, the symmetry of not only attractive in appearance but also assurance device.Have on the pressing plate 4 and be used for along reserving the elongated slot 15 that hole 14 diameter of axle directions move, thereby can adjust because the error between pipeline and the hole sealing collar is avoided turning up of watertight rubber plate 3.Doughnut-shaped steel plate 2 inside walls are provided with some dowels 1, and the end of dowel 1 is a hook portion 16, and hook portion 16 stretches in the seepproof screen 7.
After push pipe is finished,, the processing of reserving hole 14 is divided into dual mode according to building manhole in the active well by laying bricks or stones or directly utilizing the different situations of active well as manhole.
As shown in Figure 3, when building manhole by laying bricks or stones in the active well, the closely knit filling fine-stone concrete 9 in the gap between open caisson hole and the service pipe, and remove recycling component such as nut 5, pressing plate 4.
