Abstract
The invention discloses a preparation method of a prestressed steel cylinder concrete tube capable of installing a real-time detection device, comprising two sets of technology, wherein the first set of technology is suitable to simultaneously use with the technology for preparing the traditional prestressed steel cylinder concrete tube; the second set of technology is suitable for improving the traditional prestressed steel cylinder concrete tube into the concrete tube disclosed by the invention and comprises six working procedures, namely materials selecting, prefabricating of a connecting piece and a locating piece, connecting piece and the locating piece installing and punching; the connecting piece with an inner cavity space is embedded into inner-layer concrete positioned on one end of a socket steel ring; one end surface of a tube core is provided with a plurality of locating pieces; and the socket steel ring is provided with a through hole communicated with the inner cavity of the connecting piece. According to the preparation method, the problem that systematic integrated monitoring and management has big possibility to be formed because variable data can not be simply collected for a long term by the existing detection equipment when the traditional water supply engineering is monitored and maintained is solved.
Description
Technical field:
The present invention relates to concrete field, particularly relate to and a kind of Prestressed concrete cylinder pipe of real-time detector part and preparation method thereof is installed.
Background technology:
Prestressed concrete cylinder pipe (Prestressed concrete cylinder pipe, be called for short: PCCP) be the novel pipeline material grown up in domestic nearly more than ten years, the tubing of a kind of high strength, high permeability resistant and high leakproofness, in reality, this tubing be widely used in city to, draining and industrial water delivery, irrigation water, power-plant makeup field backbone pipeline engineering in, in addition, also use in a large number at plant pipe network and inverted siphon, pressure tunnel pipe, dark earthing culvert pipe.
In water supply field, long-range with in the water supply project of urban water, the distribution of aqueduct often relates to distance, distribution is wide, region span is large, the feature such as the use amount of Prestressed concrete cylinder pipe is large, this type of engineering project, usually with city even a regional people's life, produce and the factor such as stable and united of whole community closely related, it is the emphasis people's livelihood foundation engineering of country, therefore to its monitoring and management work, ought to accomplish in time, accurately, effectively can make the life of the people, the property producing even country and the people obtains and ensures, but, at present to supervision and the maintenance aspect of this type of foundation engineering, substantially the backward aspect that dependence is manually carried out patrolling and judge by rule of thumb that whether normal pipeline is is rested on, be difficult to form systematic concentrated monitoring and management, its reason is mainly forming the variable data concentrating monitoring and management, cannot be undertaken for a long time by existing checkout equipment, easy collection, because existing PCCP pipe there is no the connector and space that are exclusively used in and install real-time detector part, but can not be random add on PCCP pipe on some connectors or space, otherwise PCCP can be caused to manage original serviceability and parameter changes, make it not reach standard-required and have a strong impact on construction quality.
Summary of the invention:
In order to the state that the pipeline monitoring and management work that change current China water supply project fall behind, be necessary that very much research and development are a kind of and Prestressed concrete cylinder pipe of real-time detector part and preparation method thereof is installed, and the method also needs to be adapted at existing Prestressed concrete cylinder pipe adds real-time detector part, so that the water supply pipe utilizing existing resource to align in use is rectified and improved.
