Description
Technical field
This utility model belongs to the realm of building construction, is related to a kind of sleeve pipe distribution device for elephant trunk delivering concrete.
Particularly under the slope such as box culvert, channel, inverted-siphon, aqueduct during field work such as water conservancy, electric power, mine, agricultural irrigation
The basis of concrete structures, underplate concrete, the pouring of short concrete structures.Equipment investment is few, operating cost is low, section
Save construction investment, durable, fault rate is low, saves the duration.
Background technology
At present when the construction such as water conservancy, electric power, mine industry pours basic under heavy grade and structures concrete, because
The gradient excessive (needs of stability of slope) is it is impossible to directly repair the roads (or expense is very big) to pouring location, water conservancy industry is generally adopted
Cheat lower or neighbouring method power industry with repairing the roads to then using the method for elephant trunk.During using the method repaired the roads, investment is significantly
Improve, sometimes even infeasible.Elephant trunk method because inner-walls of duct need slip send before moistening, slip and send the rear mortar of time length to exist
The solidification of above inner-walls of duct and left and right or the solidification that causes when higher of temperature lead to slip send fault, simultaneously as concrete is from stirring
Mix that the time slipping between sending is longer, lead to concrete slump loss exceeded specification regulation through when slump-loss value.
Also have using pump truck pumping, the method put in storage of material distributing machine cloth, but pumping method need to repair the roads, simultaneously need to concrete according to
The specification of pumping carries out mix Design, and the gel material content such as cement must reach 300kg/m3More than, increased
Construction investment, simultaneous pumping concrete pumping smoothly must increase water-cement ratio, causes the loss that concrete strength is larger, Er Qienai
Property is poor long.The investment of material distributing machine method is larger, and apart from remote when just inapplicable.The method now directly put in storage using chute is
Feasible also most economical, but current elephant trunk is usually used is steel pipe, easily to be not easy displacement, discharging opening fixing not for abrasion, heaviness
Beneficial to cloth, and water-wet pipeline must be used before using, now easily be spread to pour on face by eaves gutter, if earth foundation is just
Base surface can be caused unqualified.And steel pipe necessarily be in a kind of straight line angle, installation accuracy requirement is very high, is not otherwise to produce
Raw plugging is exactly to produce isolation.When producing concrete disintegration, the slump of concrete can only be adjusted, and the linearity from steel pipe
Adjust with angle, bother very much.
Utility model content
The purpose of this utility model is for above technical deficiency, provides a kind of sleeve pipe for elephant trunk delivering concrete
Distribution device.Equipment investment is few, operating cost is low, cost saving, durable, fault rate is low, save the duration.
For achieving the above object, adopt the following technical scheme that
A kind of sleeve pipe distribution device for elephant trunk delivering concrete, including hopper, under slip straight tube, bend pipe, straight tube, blanking
Pipe, 3-60 JIEMI length (nominal diameter dn125mm-dn350mm) straight tube, elephant trunk is connected into by flange, is fitted between flange
Leakproof rubber cushion, elephant trunk top first segment straight tube is provided with axial flow blower, and each section straight tube is provided with fog generator；
Flange bridge piece is passed through in elephant trunk top first segment straight tube upper end, and bend pipe diameter is identical with straight tube, bent arc radius
R300mm-r2000mm, arc length 400mm-3000mm；
Hopper discharging opening connect under slip straight tube, under slip straight tube nominal diameter dn100mm-dn300mm, length 500mm-
2000mm, under slip 60 degree -85 of straight tube horizontal sextant angle degree, under slip in straight tube insertion bend pipe；Hopper is erected on hopper base, hopper
Water tank is arranged on support, draws water pipe from water tank, water pipe is connected one by one with fog generator；
Elephant trunk tail end final section straight tube is connected with tremie pipe one end by flange, and tremie pipe is plastic-steel products compound tube,
Internal layer is pe or pp plastics, and outer layer is steel, and tremie pipe inner layer plastic tube nominal diameter is identical with straight tube, and outer layer pipe rolls chi
Very little one hanger is welded with tremie pipe outer layer pipe with inner layer plastic tube external diameter interference fit, cloth casing pipe sleeve on tremie pipe,
Cloth sleeve pipe is steel pipe, nominal diameter dn150mm-dn400mm, length 3-9 rice, and cloth sleeve pipe has width 15mm- vertically
30mm groove, length 2.8-8.8 rice.
Compared with prior art the beneficial effects of the utility model are as follows:
1, adopt fog long-term wet channels inwall in elephant trunk, reduce the frictional resistance slipping under material, reached low
In 300The effect of delivering concrete under slope, overcomes the drawbacks of can not directly add water compensation slump-loss simultaneously；
2, elephant trunk adopts plastic tube (pe, pp pipe etc.) or plastic tube to be combined with steel pipe, can be arranged to slight s during abrupt slope
Type pipe, solves the problems, such as aggregate segregation during abrupt slope, and lower end can be lifted and swing simultaneously, has both solved reduction discharging section
The problem of material speed, also achieves voluntarily cloth, solves the problems, such as that elephant trunk is unable to cloth；
3, construct the intermission, in 10h, be not required to wash pipe, pipe need not be moistened with water during beginning, both alleviate labor intensity, and also solved
Base surface can not have the problem of water；
4, trucd mixer can directly under expect hopper, hopper can voluntarily be adjusted with the height of bend pipe upper port, it is to avoid
Uneven road causes the problem that aggregate bin is higher than trucd mixer discharging opening；
5, during gentle slope, directly the place digging machine in side slope upper shed excavates out chain-wales, hopper and water tank, letter
Folk prescription just, is not necessary to when gentle slope fill or makes discharging platform, solves the problems, such as to improve initial velocity during gentle slope；
6, by the adjustment in step, cover 1:2-1:0.5(21.800-63.430) side slope in the case of elephant trunk mix
Solidifying soil conveying scope, have also been enlarged the range of elephant trunk technology；
7, during using plastic tube, overall weight is light, and on slope, pipeline manually can adjust and mobile, the water consumption of fog device
Also very little, will not be limited by field condition.
8, supporting trolley track is made using channel-section steel, is easy to manually move.
9, abrupt slope slips straight tube at present and tilts 700-850, material againsts tube wall when falling immediately, and smooths along bend pipe
Flow forward, it is to avoid fall behind the bounce-back segregation phenomenon that excessive velocities cause under straight line.
