Abstract
The utility model discloses a skip and cageway isolating structure for a combined shaft. The skip and cageway isolating structure for the combined shaft comprises the cylindrical combined shaft, wherein the cylindrical combined shaft is partitioned into a skip and a cageway by a concrete partition wall in the longitudinal direction, reinforcement bars are uniformly distributed in the concrete partition wall, a s haft wall of the combined shaft is connected with the reinforcement bars in the concrete partition wall through planted bars, and the planted bars are connected with the reinforcement bars in the concrete partition wall through sleeves. The concrete partition wall is formed in a manner that after the shaft wall of the combined shaft is finished, dabbing is performed on the shaft wall nearby the planted bars, and then slip form conduction is performed from the bottom to the top of the combined shaft.
Description
Technical field
The utility model relates between the combined shaft skip bucket and the cageway isolation structure.
Background technology
In recent years, along with the superficial part resource reduces and exhaustion gradually, the a lot of pit mining degree of depth of China increase to 700～800m from 200 initial～300m, and the mining depth of many mines has reached 1000～1200m, when geologic condition or hydrologic condition are complicated, building major and minor pit shaft needs long construction period and very big fund input, and under this background, middle-size and small-size mine adopts the combined shaft lifting scheme can obtain better economic results.
" metal and nonmetal mine safety rules " are 6.3.3.5 bar regulation (GB16423-2006): the combined shaft of no isolation facility, in lifting personnel's time, the skip hoisting system should stop running.6.4.2.5 bar regulation: when combined shaft is made downcast, should take the actv. control techniques, to guarantee the wind regime quality.
Between the skip bucket of combined shaft and between the cageway isolation facility is being set, can making combined shaft have the function of downcast function and two cover lifting container independent operatings simultaneously, making full use of pit shaft, reducing the effect of investment thereby play.
As follows between skip bucket at present with the existing way of cageway isolation facility:
1. vertically with a determining deviation girder steel is set at pit shaft, the fixed form of the girder steel and the borehole wall adopts hitch or anchor pole bearing.
2. the dividing plate with certain specification is fixed by bolts on the girder steel.Dividing plate can adopt steel, glass-felt plastic or glass fiber reinforced plastics composite material.
3, airtight measure is taked in the space between dividing plate and dividing plate, dividing plate and girder steel, dividing plate and the borehole wall, guarantees not leak out.
The problem that exposes with the cageway isolation facility between the skip bucket of down-hole is as follows at present:
1. steel diaphragm is difficult in maintenance.The anticorrosion general employing paint of steel diaphragm, arc spraying cathode protection material, outsourcing glass-felt plastic mode.Preservative coat side between skip bucket is impacted by fine ore easily to come off, to lose protective effect, and carry out anticorrosion difficulty of later stage in the down-hole very big.Will in time change after the dividing plate corrosion, the replacement cycle is long, difficulty is big, expense is high; If repair and maintenance is not in place, dividing plate is prone to falling accident, has a strong impact on lifting safety.
2. the glass-reinforced plastic material impact resistance is poor.If what fall during the skip bucket loading and unloading is lump ore, can in dropping process, form very big impulsive force and energy.If dividing plate is broken by the impact, the ore deposit rock that skip bucket scatters might be fallen on the cage or in the cage, causes the elevator system accident.As the people is arranged in the cage, accident will cause casualties.
3. the space between dividing plate and dividing plate, dividing plate and girder steel, dividing plate and the borehole wall is difficult to keep for a long time air-tight state, occurs leaking out.
4. when the fixed form of the girder steel and the borehole wall adopted hitch, difficulty of construction strengthened; When the fixed form of the girder steel and the borehole wall adopts the anchor pole bearing, between the dividing plate and the borehole wall, be difficult between dividing plate and the girder steel airtight.
5. when lifting container moved in the pit shaft, because " bellows " effect, the dividing plate both sides produced pressure reduction, and reciprocal side travel can appear in dividing plate, causes safety gap to reduce, dividing plate generation endurance failure.
The utility model content
Technical problem to be solved in the utility model is, at the prior art deficiency, provides a kind of and safeguards simple, good impact resistance, obturation effect is good and can reduce between the combined shaft skip bucket of bellows effect and the cageway isolation structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: between a kind of combined shaft skip bucket with the cageway isolation structure, comprise a columniform combined shaft, vertically being divided into by concrete partition of this combined shaft reaches cageway between skip bucket, be evenly equipped with reinforcing bar in this concrete partition.
The borehole wall of this combined shaft is connected with reinforcing bar in the concrete partition by bar planting, and bar planting adopts sleeve to be connected with the reinforcing bar of concrete partition.
This concrete partition is after the borehole wall of combined shaft is finished, and with near the cutter of the borehole wall bar planting hair, adopts the construction of sliding formwork method from the bottom to top from the combined shaft bottom then earlier.
This concrete partition adopts from carrying structure, i.e. concrete partition unit height deadweight equals the shearing resistance carrying of unit height reinforcement planting.
The thickness of this concrete partition is 180～250mm.
The diameter of this bar planting is φ 12mm～φ 28mm.
Compared with prior art, the beneficial effect that the utility model had is:
1. the concrete partition corrosion stability is strong, does not need substantially to safeguard.
2. concrete partition strong shock resistance, the cageway safe in operation is not subjected to spread between skip bucket the ore deposit to be influenced.
3. the concrete diaphragm obturation effect is good, has avoided polluting distinguished and admirable because of skip bucket a large amount of dust pollutions of producing in the process of loading and unloading ore enter mine.
4. the concrete diaphragm lateral rigidity is big, and " bellows " effect can be ignored during the container operation.
5, easy construction, technical maturity can significantly reduce construction costs, shorten the completion time of project.

The specific embodiment
As shown in Figure 1, the utility model comprises a columniform combined shaft 1, this combined shaft 1 vertically be divided between skip bucket 2 and cageway 4 by concrete partition 7.Be the intensity of reinforced concrete partition wall 7, be evenly equipped with the reinforcing bar (not shown) in this concrete partition 7.The borehole wall of this combined shaft 1 is connected by the reinforcing bar in bar planting 8 and the concrete partition 7, and bar planting 8 is connected with the reinforcing bar employing sleeve mode of concrete partition 7.This concrete partition 7 adopts back way construction: after the borehole wall of combined shaft 1 is finished, earlier with bar planting 8 residing borehole wall positions cutter hair, adopt sliding formwork method construction concrete partition 7 then from the bottom to top from the combined shaft bottom.This concrete partition 7 adopts from carrying structure: the deadweight of concrete partition 7 unit height is by unit height reinforcement planting 8 shearing resistances carrying, and partition wall 7 is not established post and beam construction.The thickness of concrete partition 7 is 180～250mm, determines owing to moving the factors such as difference of pressure that cause easily according to width, construction technology, concrete partition 7 both sides of concrete partition 7.The diameter of this bar planting 8 is φ 12mm～φ 28mm.
