Novel visual intelligent super-fluid cast-in-place concrete pile device and construction method

Abstract

The invention relates to a novel visual intelligent super-fluid cast-in-place concrete pile device and a construction method. The novel visual intelligent super-fluid cast-in-place concrete pile device comprises a walking and crawler type main machine, a winding machine, a guide rod, a steel wire rope, a feed inlet, a power head, a gearbox, a speed reducer, a spiral drill rod, a drill bit, a feed outlet, a pump truck guide pipe, a concrete pump truck, a flow meter and a depth sensor, wherein the winding machine and the guide rod are fixedly arranged on the main machine, the power head is connected with a pulley arranged at the top end of the guide rod through the steel wire rope, the steel wire rope drives the power head to ascend and descend, the power head is sequentially connected with the spiral drill rod through the gearbox and the speed reducer, the lower end of the spiral drill rod is connected with the drill bit, the feed outlet is formed in the drill bit and is provided with an iron sheet, the iron sheet is fixed by a bolt, the concrete pump truck is connected with the feed inlet through the pump truck guide pipe, and the pump truck guide pipe is provided with the flow meter. The invention also provides the construction method of a novel visual intelligent super-fluid cast-in-place concrete pile. The construction method comprises the steps of firstly, drilling to a design depth by a long spiral drilling machine; then, forwards rotating or directly lifting the drill rod; continuously infusing super-fluid concrete in a hole through a drill bit valve while pulling out the drill rod; finally, inserting a steel reinforcement cage after pulling out the drill rod. Compared with the prior art, the novel visual intelligent super-fluid cast-in-place concrete pile device and the construction method, provided by the invention, have the advantages that no noise or vibration is generated, a soil compaction performance is not generated, intelligentization is realized, the quality is ensured, the cost is reduced, the construction period is shortened, and the like.

Description

technical field [0001] The invention relates to a novel visualized intelligent superfluid concrete pouring pile device and a construction method, which are mainly used in foundation pit enclosure retaining soil and main structure vertical stress in civil and industrial infrastructure construction. Background technique [0002] At present, the conventional concrete cast-in-place pile construction methods include dry-work bored piles, mud retaining wall bored piles, casing bored piles, and blast-expanded bored piles, etc. [0003] The construction process of cast-in-situ piles in dry operation: site cleaning → measuring and setting out the pile position → placing the pile machine → drilling and taking soil to form the hole → removing the sediment at the bottom of the hole → inspection and acceptance of the hole quality → hanging and placing the reinforcement cage → pouring Concrete in the hole. [0004] The cast-in-situ piles with mud arm guards use mud to protect the wall. W...

Problems solved by technology

At present, the construction of concrete pouring piles has the disadvantages of wasting concrete and high cost. At the same time, the construction period also needs to be improved. The degree of intelligence of construction machinery is not high. In many cases, the addition of materials is based on the experience of the on-site staff, which cannot be carried out well. monitoring management

[0007] The original method of pressure grouting piles is not equipped with a visual intelligent system, the quality of the pile body is poor, and the quality of pile formation is uncontrollable
