Abstract
A pipe orifice of a prestressed steel-cylinder concrete pipe comprises the following components: a receiving socket which is provided with receiving socket ring, and an insertion socket which is provided with an insertion socket ring, wherein the receiving socket and the insertion socket are provided at two ends of the pipe orifice. The pipe orifice of the prestressed steel-cylinder concrete pipe is characterized in that: the length value of an operation surface of the receiving socket ring is increased for 8-12mm; a beveling angle beta outside the receiving socket ring is improved to 29-35.5 DEG; and an inclination angle alpha of the end face of the receiving socket ring or the insertion socket ring is 2-3 DEG. The pipe orifice of the prestressed steel-cylinder concrete pipe has the following advantages: enlarging an allowed relative rotation angle of the pipe joint of the prestressed steel-cylinder concrete pipe, improving capacity of the pipe for resisting uneven settlement, reducing maintenance cost of an engineering pipe, prolonging service life of the pipe, and ensuring safe and economical operation of the engineering pipe.
Description
Technical field:
The utility model belongs to the Prestressed concrete cylinder pipe field, particularly a kind of Prestressed concrete cylinder pipe mouth of pipe.
Background technique:
Prestressed concrete cylinder pipe is the composite pipe that raw and auxiliary materials such as set sheet metal, medium steel plate, deformed steel, high-strength prestressed steel wire, ordinary steel bar, high-strength concrete, high-strength mortar and rubber seal are processed; Have characteristics such as high tenacity, high permeability resistant and high leak tightness because of it and be widely used in engineerings such as urban water supply and drainage, industrial waterline, field irrigation, plant pipe network, power-plant makeup and cooling water recirculation system, inverted siphon, pressure tunnel pipeline and dark earthing culvert pipe, be particularly suited for the engineering-environment of heavy caliber, senior engineer's pressure and high earthing.Yet; This at home tubing is closely just to grow up during the last ten years; Construction quality and applicable cases also do not obtain the checking of enough time; According to State Standard of the People's Republic of China " Prestressed concrete cylinder pipe (GB/T19685-2005) " regulation, it is 0.5～1.5 ° that the pipe coupling of the Prestressed concrete cylinder pipe of nominal bore diameter 400-4000mm allows relative rotation, the strength disposal that so little relative rotation is big for the uneven settlement amount, mud soft soil foundation just needs to strengthen ground or basis; Not only to strengthen difficulty of construction, but also can increase investment and prolong the duration.Therefore NBS " Prestressed concrete cylinder pipe " (GB/T19685-2005) is pointed out " according to the pipe engineering actual conditions, when carrying out the tube construction design, can suitably increase pipe coupling and allow relative rotation " simultaneously.Allow relative rotation to strengthen the adaptive capacity of pipe through increasing pipe coupling to the soft soil foundation uneven settlement.
Summary of the invention:
The purpose of the utility model is to overcome the deficiency of existing technology; A kind of Prestressed concrete cylinder pipe mouth of pipe is provided; The pipe coupling that this concrete pipe can increase Prestressed concrete cylinder pipe allows relative rotation, strengthens the ability that tubing is resisted uneven settlement of foundation, reduces the maintenance cost of utilities pipeline; Prolong pipeline working life, ensure the utilities pipeline safety and economic operation.
As above design, the technological scheme of the utility model is: a kind of Prestressed concrete cylinder pipe mouth of pipe, bellmouth that has the bellmouth ring that comprises mouth of pipe two ends and the socket that has the socket ring is characterized in that: the length value of bellmouth ring working surface is increased by 8～12mm; The outer adverse slope angle beta value of bellmouth ring is increased to 29～35.5 °; The angle of inclination a that makes bellmouth ring end face or socket ring end face is between 2～3 °.
Above-mentioned bellmouth ring working surface leaves the gap of 0.6mm～1.0mm when cooperating with socket ring working surface.
The utlity model has following advantage and good effect:
1, the utility model can increase the amount of extracting that allows of pipe coupling, improves pipe coupling and allows relative rotation more than one times, strengthens the ability that tubing is resisted uneven settlement of foundation, effectively reduces the intractability and the investment on ground or basis.
2, the utility model simple in structure, easy to use, have good performances such as high tenacity, high permeability resistant, and can not increase the tubing manufacture cost.
3, the utility model make tubing when mounted counterpart easily, be convenient to construction, improve installation efficient, reduce construction cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
As shown in the figure: a kind of Prestressed concrete cylinder pipe; By in the outer felt of the concrete tube core 4 that has bellmouth steel loop 1 and socket steel ring 2 steel cylinders 3 around reinforcement wire 5 and make cement mortar protective course 6 and process, the bell of pipe and socket joint seal with rubber seal 7 during installation.
When making the bellmouth steel loop, shorten the outer adverse slope length alpha value of bellmouth 8～12mm, make bellmouth face length b value increase by 8～12mm, the outer adverse slope angle beta of bellmouth is increased to 29～35.5 ° simultaneously.
When making socket steel ring, adopt the socket steel ring that meets People's Republic of China's building material industry standard " the Prestressed concrete cylinder pipe joint is with shaped steel (JC/T1091-2008) " requirement fully to use shaped steel.
The bellmouth working surface of finished product tubing leaves the gap c of 0.6mm～1.0mm when cooperating with the socket working surface.
Making the angle of inclination a of bellmouth end face or socket end face when making tube core is 2～3 °.
It is 50～65IRHD that Prestressed concrete cylinder pipe bellmouth and socket joint use rubber seal to adopt shore hardness, and diameter of section is the solid cushion rubber of the jointless die pressing circular cross-section of 20mm.
Claims (2)
1. Prestressed concrete cylinder pipe mouth of pipe comprises it is characterized in that the bellmouth that has the bellmouth ring and the socket that has the socket ring at mouth of pipe two ends: the length value of bellmouth ring working surface is increased by 8～12mm; The outer adverse slope angle beta value of bellmouth ring is increased to 29～35.5 °; The angle of inclination a that makes bellmouth ring end face or socket ring end face is between 2～3 °.
2. the Prestressed concrete cylinder pipe mouth of pipe according to claim 1 is characterized in that: above-mentioned bellmouth ring working surface leaves the gap of 0.6mm～1.0mm when cooperating with socket ring working surface.
