Description

A kind of slurry accident pool and construction method thereof
Technical field
The present invention relates to slurry and deposit technical field, relate to more specifically a kind of novel slurry accident pool and mode of construction thereof, especially relate to a kind of ore pulp accident pool and mode of construction thereof for the iron ore concentrate pipeline transportation.
Background technology
In the transportation of current slurry pipeline, slurry body tends to because overflow and defeated leakage occur in various production accidents, therefore prior art generally will be built the slurry accident pool when carrying out Slurry Pipeline Transportation, especially in the iron ore concentrate pipeline transportation, the construction of slurry accident pool is very necessary, this slurry accident pool is for collecting in time slurry pipeline because of accident overflow or the defeated slurry spilt, especially ore pulp.This slurry accident pool of the prior art as shown in Figures 1 and 2, it is built in the absolute altitude on ground 1 ± more than 0, and structure as shown in Figures 1 and 2, protrudes from the rectangle steel reinforced concrete pool on ground, comprise at the bottom of pond 3 and pool wall 2, at the bottom of pond, 3 are built on ground 1.In the transportation of slurry pipeline, slurry can flow in the slurry accident pool shown in accompanying drawing 1 due to various production accidents, in the course of time, slurry material 4 in the slurry accident pool just runs up to certain amount, need to be cleared up it, if removed not in time, will affect the operating efficiency of slurry accident pool, once just the slurry solid accumulation in accident pool can not be brought into play its effect after expiring again.In view of the structural texture of slurry accident pool shown in accompanying drawing in prior art 1 and accompanying drawing 2, often adopt three kinds of methods to be cleared up the slurry material 4 deposited in the slurry accident pool: (1) hangs in loader in the slurry accident pool and is cleared up with crane; (2) under the condition allowed at orographic condition, set up support, loader is cleared up in support drives the slurry accident pool into; (3) the slurry accident pool being opened to an openning allowing loader from the sidewall of its protrusion enters.These three kinds of the prior art exist following problem to the deposition material method of being cleared up in the slurry accident pool: (1) hangs in loader in accident pool while being cleared up with crane, cleaning will be all a larger cost payout each time, because the usage charges of a crane just approach ten thousand yuan, but also needing the wait crane to march into the arena, this mode tends to expend plenty of time and financial resources; (2) adopt and to set up support and make loader drive the mode of accident pool into along support, need to make in advance support and be installed according to topographic features, after finishing using, also need to be removed, and support also needs to be kept properly while not using, not only increased the manufacturing cost of support, and also can produce the labour cost of great number in its installation, demolishing process, and cause cost of production to increase, also can there is potential safety hazard; (3) accident pool is opened to the manner of cleaning up that an openning allowing loader enters, because the slurry accident pool is generally concrete structure, need destroy original structure when opening openning, and the curing time that concrete need be longer when recovering, during this period of time, the slurry accident pool can not be used, even after recovering, also there will be drainage at accident pool openning seam crossing, cause this manner of cleaning up to have a strong impact on the application life of slurry accident pool, and reduced production efficiency.Therefore in this slurry accident pool, the cleaning problem of deposition slurry material has become technical barrier urgently to be resolved hurrily in the Slurry Pipeline Transportation process.
