AI Technical Summary
In the construction of pile foundations of transmission lines, the depth of artificial hole-drilling piles is large, resulting in high drop height during the pouring process, which is prone to separation. In construction sites far away from the city, traffic is difficult and concrete pouring conditions are poor, resulting in a decline in the quality of the pile foundation.
A concrete pouring device is designed, including a funnel and a flexible string barrel. The string barrel is sleeved outside the funnel and is lifted at the hole pile by a lifting chain. The flexible string barrel limits the concrete drop, reduces the separation, and shortens the length of the string barrel through a draw rope to prevent blockage, so that the string barrel can shrink and facilitate transportation.
It effectively reduces the separation of concrete and improves the quality of pile foundations. It is suitable for construction sites far away from cities and difficult traffic, making it convenient for transportation and installation.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete pouring, and in particular relates to a concrete pouring device. Background Art
[0002] At present, when constructing pile foundations for power transmission lines, manual bored piles and concrete pouring are often used. However, the depth of manual bored piles is usually more than 5 meters, and it is not uncommon for the depth to be greater than 12 meters. This causes the concrete to fall to a high height during the pouring process, and segregation is likely to occur during the falling process. At the same time, the pile foundations of power transmission lines are usually far away from cities, and transportation is difficult, so the concrete pouring conditions are poor. When pouring directly into the bored piles, it is easy to cause the pile foundation quality to decline due to concrete segregation. Utility Model Content
[0003] The utility model provides a concrete pouring device to overcome the defects of the prior art and can reduce concrete segregation.
[0004] The purpose of the utility model is achieved through the following technical solutions:
[0005] A concrete pouring device, comprising:

[0007] The string tube is a flexible string tube, the upper part of which is sleeved outside the funnel, the upper end of which is connected to the outer side of the funnel, and the diameter of which is smaller than the diameter of the hole pile;
[0008] A pull rope, one end of which is connected to the lower end of the string tube.
[0009] The beneficial effects of adopting the above technical solution are as follows: after the string tube is connected to the funnel, it can be hoisted at the hole pile with the funnel, and the lower part of the string tube can extend to the lower part of the hole pile, that is, after the concrete is put into the funnel, the flexible string tube can limit the free fall of the concrete, thereby reducing the segregation of the concrete; in addition, during the pouring process, the lower end of the flexible string tube can be pulled up by a pull rope, so as to shorten the total length of the string tube during the pouring process, thereby preventing the lower end of the string tube from being submerged in concrete and causing blockage; at the same time, the flexible string tube can be retracted to facilitate collection, transportation and carrying, which is conducive to pouring construction at the pile foundation of the transmission line far away from the city and with difficult transportation.
[0010] In one embodiment, a plurality of support rings are arranged in the string tube along the length direction.
[0011] The beneficial effect of adopting the above technical solution is that such an arrangement makes it convenient to retract the string tube upward through a plurality of support rings when the pull rope is pulled upward.
[0012] In one embodiment, the outer diameter of the support ring matches the inner diameter of the string barrel.
[0013] In one embodiment, the draw cord is located outside the string drum.
[0014] The beneficial effect of adopting the above technical solution is that such an arrangement is convenient for installing the pull rope and for pulling the pull rope outside the string tube.
[0015] In one embodiment, a plurality of pull ropes are evenly connected to the lower end of the string tube along the circumferential direction.
[0016] The beneficial effect of adopting the above technical solution is: such an arrangement is conducive to evenly stressing the lower end of the string tube, thereby facilitating the vertical upward contraction of the string tube.
[0017] In one embodiment, a plurality of lifting chains are evenly connected to the outer side of the funnel along the circumferential direction.
[0018] The beneficial effect of adopting the above technical solution is: such an arrangement is conducive to making the funnel evenly stressed, thereby facilitating the lifting of the funnel.
[0019] In one embodiment, a plurality of lifting ears for connecting lifting chains are provided on the outside of the funnel.
[0020] In one embodiment, the upper end of the string barrel is connected to the lifting lug.
[0021] The beneficial effect of adopting the above technical solution is: such an arrangement makes it convenient for the string tube to be put on the funnel after shrinking, thereby facilitating collection and transportation with the funnel.
[0022] In one embodiment, the string barrel is detachably connected to the lifting eye.
[0023] The beneficial effect of adopting the above technical solution is: such an arrangement makes it easy to remove the string tube from the funnel, which is convenient for replacement and separate transportation.
[0024] In one embodiment, the string tube is a Kevlar dipped fiber string tube or a polyethylene woven fabric string tube.
[0025] The beneficial effects of adopting the above technical solution are: both the Kevlar dipped fiber string tube and the polyethylene woven fabric string tube have both wear resistance and flexibility, and are lightweight materials, which not only meets the flexibility requirements of the string tube, but also can increase the service life of the string tube, and is also convenient for transportation.
[0026] The beneficial effects of the utility model are:
[0027] After the string tube is connected to the funnel, it can be hoisted at the hole pile with the funnel, and the lower part of the string tube can extend to the lower part of the hole pile, that is, after the concrete is put into the funnel, the flexible string tube can limit the free fall of the concrete, thereby reducing the segregation of the concrete; in addition, during the pouring process, the lower end of the flexible string tube can be pulled up by a pull rope, so as to shorten the total length of the string tube during the pouring process, thereby preventing the lower end of the string tube from being submerged in concrete and causing blockage; at the same time, the flexible string tube can be retracted to facilitate collection, transportation and carrying, which is conducive to pouring construction at the pile foundation of the transmission line far away from the city and with difficult transportation.
