Concrete pouring device for cast-in-place pile construction

Abstract

The invention discloses a concrete pouring device for cast-in-place pile construction in the technical field of concrete pouring, and the concrete pouring device comprises a pouring pipe, a pouring hole is formed in the pouring pipe, the pouring pipe is rotatably connected with a first rotating ring, the first rotating ring is slidably connected with a sliding sleeve in the vertical direction, and a wave sliding groove is formed in the inner circumferential wall of the sliding sleeve; the wavy sliding grooves are connected end to end to form an annular shape. A first guide sliding block is slidably connected into the wave sliding groove and fixedly connected with the infusion tube. A stirring block is fixedly connected to the sliding sleeve, a driving assembly is arranged on the outer side of the sliding sleeve, and the driving assembly is used for driving the sliding sleeve to rotate; the compaction of concrete can be accelerated, when the cast-in-place pile is filled with the concrete, the concrete is in a compact state, and the progress of concrete pouring can be greatly accelerated.

Description

technical field [0001] The invention relates to the technical field of concrete pouring, in particular to a concrete pouring device used for the construction of cast-in-place piles. Background technique [0002] With the rapid development of high-speed railways in my country, there are more and more tunnels. In the construction of tunnel excavation, it is easy to encounter the situation of loosely accumulated soil, backfill and other under-consolidated soil layers, resulting in the occurrence of The overall or local settlement of the tunnel, in the process of tunnel excavation and support, there are problems such as insufficient support strength, large deformation of the surrounding rock of the tunnel, and damage to the support structure, which are important for the safety of the tunnel support structure and the stability of operation. It brings a great threat. In order to solve the settlement problem of the tunnel under this special bottom layer, the construction of the cast-...

Problems solved by technology

[0003] Existing bored cast-in-place piles usually adopt drilling machine drilling (or manual drilling) during construction, then prefabricated reinforcement cages are hoisted in the holes, and then pipes are used to pour concrete; Deeper, the traditional vibrating rod cannot reach the bottom of the cast-in-place pile, and the concrete can only rely on the slump of the concrete itself to ensure the compactness of the concrete after it is transported from the conduit to the bottom of the cast-in-place pile; The appearance of air bubbles will seriously reduce the bearing capacity of the installation, and relying entirely on the slump of the concrete to ensure the compactness of the concrete will lead to a slow progress in concrete pouring
