Abstract
The utility model provides an anticorrosion pipe shaft injection device with a polyvinyl chloride (PVC) liner. The anticorrosion pipe shaft injection device comprises an outer mold and an inner mold, wherein the inner mold is arranged inside the outer mold. The inner mold is a cylindrical mold, a circle of adverse slope is arranged at the top end of the cylindrical mold, a gland is arranged on the adverse slope, and a plurality of protruding edges are arranged on the outer side wall of the cylindrical mold along the axial direction. The anticorrosion pipe shaft injection device has the advantages that the adverse slope and the gland are arranged on the cylindrical mold, the upper edge of the PVC liner can be bent and pressed under the gland along the adverse slope, and therefore the phenomenon that slurry leaking to the gaps between the PVC liner and the cylindrical mold causes wastes in the process of injecting armored concrete can be avoided. The protruding edges are arranged on the outer side wall of the cylindrical mold, and therefore the phenomenon that the PVC liner is damaged because the PVC liner is attached to the cylindrical mold closely and is difficult to demold can be avoided. The anticorrosion pipe shaft injection device has the advantages of reducing cost, being simple in structure, convenient to maintain and high in work efficiency and product quality, saving cost and the like.
Description
Technical field
The utility model relates to a kind of piping shaft notes and uses device, especially relates to a kind of anti-corrosion pipeline well notes device with the pvc liner.
Background technology
Piping shaft is the auxiliary construction of looking into, remove foreign matter for the maintainer manual inspection, to be convenient to make regular check on and dredging pipeline, prevent the necessary facility of line clogging, the piping shaft inside of prior art is provided with the pvc liner, and piping shaft generally forms by the reinforced concrete perfusion, the used mould of its perfusion generally comprises external mold and internal mold, described internal mold is a cylindric device, exists after perfusion is good, when the demoulding, it is outer that mud may leak into the pvc liner, causes product defective; Also exist when the demoulding, because pvc inner liner and mould applying is very tight, cause demoulding difficulty, usually can damage the pvc inner liner, cause the waste of cost.
Summary of the invention
Problem to be solved in the utility model provide a kind of simple in structure, demoulding easily, the anti-corrosion pipeline well with the pvc liner of saving cost annotates and use device, especially suitable high-quality, high efficiency production are with the anti-corrosion pipeline well of pvc liner.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-corrosion pipeline well with the pvc liner is annotated and is used device, comprise external mold and internal mold, described internal mold is located in the described external mold, described internal mold is a cylindrical mold, be provided with a circle adverse slope on the top of described cylindrical mold, be provided with a gland at described adverse slope, be provided with vertically some fins on the described cylindrical mold lateral wall.
Further, the cross section of described fin is triangle, and described leg-of-mutton two points are on described cylindrical mold.
Further, the cross section of described fin is rectangle or circle.
Further, described fin and described cylindrical mold are one-body molded.
Further, described fin is welded on the described cylindrical mold.
Further, the distance between per two described fins is 5-30cm.
The diameter of described adverse slope is less than the diameter of cylindrical mold.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, described cylindrical mold is provided with adverse slope and gland, the upper edge of pvc liner can bend along adverse slope and be pressed under the gland, prevent when the perfusion reinforced concrete, mud can be leaked in the space between pvc liner and the described cylindrical mold, so that products waste; Described cylindrical mold lateral wall is provided with fin, prevents pvc liner applying cylindrical mold tension, is difficult to the demoulding, prevents that liner pvc from damaging, and reduces cost, have simple in structure, easy to maintenance, high efficiency, product quality high, save the advantage such as cost.

The specific embodiment
As shown in Figure 1, a kind of anti-corrosion pipeline well with the pvc liner of the utility model is annotated and is used device, comprise external mold 1 and internal mold 2, described internal mold 2 is located in the described external mold 1, described internal mold 2 is a cylindrical mold, be provided with a circle adverse slope 3 on the top of described cylindrical mold, be provided with a gland 4 at described adverse slope 3, be provided with vertically some fins 5 on the described cylindrical mold lateral wall.
Preferably, as shown in Figure 2, the cross section of described fin 5 is triangle, and described leg-of-mutton two points are on described cylindrical mold.
Preferably, shown in Fig. 3,4, the cross section of described fin 5 is rectangle or circle.
Preferably, described fin 5 is one-body molded with described cylindrical mold.
Preferably, described fin 5 is welded on the described cylindrical mold.
Preferably, the distance between per two described fins 5 is 5-30cm.
The course of work of this example: in use, the upper edge of pvc liner is bent to be pressed in gland 4 times along adverse slope 3, thereby can prevent when the perfusion reinforced concrete, mud can be leaked in the space between pvc liner and the described cylindrical mold, so that products waste, when carrying out the demoulding, because cylindrical mold is provided with fin 5, thereby can prevent pvc liner demoulding difficulty, cause the pvc liner to cause damage, not only quality is good to utilize the utility model to produce anti-corrosion pipeline well with the pvc liner, and high efficiency.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
