Problems solved by technology

However, the purpose of this design is not to prevent external water from entering the conduit when the first pouring is performed, and the structure of the conduit head of this design is relatively complicated, and the operation of opening the nozzle when inserting into the concrete grout may be difficult due to problems from the first pouring. failure due to the greater resistance of the concrete

Embodiment Construction

[0034] see figure 1 , the figure shows the concrete pouring equipment 1 of the present invention, which includes: a conduit 2, a funnel-shaped pouring device 3 connected to the upper end of the conduit, and a nozzle sealing device 4 arranged at the lower end of the conduit.

[0035] figure 2Shown is the orifice closure 4 at the lower end of the conduit 2 . As can be seen from the figure, the spout closure device 4 comprises an upper part 42 and a lower part 41 . Both the upper part and the lower part are in the shape of a short cylinder and the two parts are concentric. The diameter of the upper part 42 is smaller than that of the lower part 41 . Since the diameter of the lower part 41 is greater than that of the upper part 42 , the lower part 41 has an annular boss 43 relative to the upper part, and the boss is used to close the lower nozzle of the conduit 2 . In other words, the diameter difference between the upper and lower parts is at least equal to or greater than th...

Abstract

The invention relates to a concrete pouring device, which comprises a guide pipe for pouring concrete, a funnel-shaped pouring guide device connected with one end of the guide pipe and a lifting device of the guide pipe, wherein the guide pipe is formed by connecting multiple sections of short pipes together through a connecting device in a hermetical manner, and the other end of the guide pipe is sealed and closed by a pipe orifice closing device in a removable manner. The invention further relates to a guide pipe type concrete pouring method using equipment including the pipe orifice closing device, the pipe orifice closing device is mounted on the guide pipe before pouring, the pipe orifice closing device is placed on a foundation along with the guide pipe, and the pipe orifice closing device can be separated from the guide pipe after the beginning of the pouring of the concrete.

Description

technical field [0001] The invention relates to a concrete pouring equipment and method, in particular to a conduit type pouring concrete equipment and method. Background technique [0002] Various pile foundation technologies are involved in the construction industry. At present, the construction of pile foundation underwater concrete pouring pile engineering usually adopts the conduit method for construction. [0003] Among the existing conduit pouring concrete technologies, there is a technology called the direct lift conduit method for underwater concrete pouring, which is to enter the concrete mixture into the initial poured concrete (as a water-resisting layer) through the conduit inlet, and jack it up. As the initial poured concrete and the mud or water on it rise gradually, a continuous and dense concrete pile body is formed. The construction technology requirements of this conduit method are very strict, and must be controlled from several aspects such as construct...
