Example Embodiment

[0022] The present invention will be further explained in conjunction with the accompanying drawings. The manufacturing technology and process flow of this device are very clear to those in the field.

[0023] 1. Production of reinforced cement mortar protection tube

[0024] 1) Construction and production of steel skeleton

[0025] Generally designed for bored piles with a diameter of 1.5m, the steel-reinforced cement mortar protective cylinder adopts Φ25 threaded steel bar in the circumferential direction, and is arranged along the length of the protective cylinder from 1.7m to 2m. Double-sided lap welding is adopted; 16 longitudinal framework bars are used. Φ16 threaded steel bars are uniformly distributed and welded on the outside of the circumferential skeleton steel bars; the tops of two longitudinal steel bars in any diameter direction are welded with lifting rings. The length of the steel frame is considered based on the ground elevation of the drilling platform minus the el...

Abstract

The invention relates to the technical field of civil engineering and construction, in particular to a reinforcement cage cement plaster pile casing and a construction process thereof. The reinforcement cage cement plaster pile casing comprises twisted steel, iron wire meshes and cement plaster, and is characterized in that the reinforcement cage cement plaster pile casing is a cylinder in shape; the cylinder is provided with a plurality of longitudinal cage ribs arranged at equal distance; the longitudinal cage ribs arranged at equal distance are provided with a plurality of toroidal cage ribs arranged at equal distance; the longitudinal cage ribs arranged at equal distance and the toroidal cage ribs arranged at equal distance are respectively provided with inner layer iron wire meshes and outer layer iron wire meshes; and the iron wire meshes are provided with the cement plaster. The reinforcement cage cement plaster pile casing has the advantages that equipment for driving and extracting a steel pile casing or reinforcement treatment is not needed, thereby, the process is simple, and the working hour is saved; a top soft soil layer can be effectively prevented from collapsing; concrete overfilling is controlled, thereby, resources are saved; a basement is stable, environmentally friendly and is safe and reliable; and the project process is ensured.

Description

[technical field] [0001] The invention relates to the technical fields of civil engineering and construction, in particular to the prefabrication and application of steel frame cement mortar casings utilizing the principle of steel bars and cement mortar structures. [Background technique] [0002] When constructing bridges and other structures in newly formed land soft ground sections near the sea, bored pile foundations are mostly used. There are soft soil layers such as silt layer and flushing layer within a certain depth on the surface of this type of foundation, and the depth can reach 8m to 10m. This type of layer has high water content, low bearing capacity, and poor self-stability. In order to prevent the top of the drilled hole from collapsing, a deepened steel casing is traditionally used to protect the top of the hole. [0003] However, the defect of this method is that special equipment for drawing the steel casing is required when drawing the steel casing, and t...
