TH54873B - Installation of pressure-resistant pipes and equipment in precast concrete piles - Google Patents

Abstract

DC60 (28/01/59) This invention is a method for installing two parallel 1/2-inch pressure-resistant pipes (HDPE) from the pile head along the specified pile length, connected to the cement slurry dispensers at both opposite ends of the pile. The equipment for connecting the pile hooks is provided so that the pressure-resistant pipes and all equipment are embedded in the concrete wall of the pile during pile casting. This is in preparation for the immediate injection of cement to adjust the geotechnical properties after the pile installation is complete. Invention Summary Edited 28/01/2016 This invention is a method for installing two parallel 1/2-inch pressure-resistant pipes (HDPE) from the pile head along the specified pile length, connected to the cement slurry dispensers at both opposite ends of the pile. The equipment for connecting the pile hooks is provided so that the pressure-resistant pipes and all equipment are embedded in the concrete wall of the pile during pile casting. This is in preparation for the immediate injection of cement to adjust the geotechnical properties after the pile installation is complete. ------------------------------------------------------------------- This invention is an invention of a method of embedding pressure-resistant pipes with cement water dispensing heads in various types of precast concrete piles during the casting of piles that must be installed by pilot drilling or digging up soil from the center of the pile until the pile can be pressed into the specified hard soil layer, then increasing the pile's load-bearing capacity with the technique of injecting cement water through pressure-resistant pipes and cement water dispensing heads embedded in the piles.

Disclaimer (all) which will not appear on the advertisement page: edit 28/1/2016 1.Installing a mortar grouting pipe with a precast concrete device Iron Reinforcing pile (2) is installed between the metal plate (14) and the end of the spike on one side. Assemble the steel plate (11), where the joint (15) of the steel plate (14) is connected with the joint (12) of the steel plate (11) with a pressure-resistant pipe (4) parallel to the pile reinforcement. (2) and tied together with steel wire (5) intermittently along the length of the pin (13) of the sheet (11) of the end of the pile on the top of the pillar (9) on both sides of the sheet ( 8) at the head of the lower pile To control the entire center of the pile And the position of the joints (12) of the steel plate (11) the position corresponding to the joints (6) of the steel plate (8), where the sealing gasket (10) is in the middle, is intended for grouting mortar. From both ends of the pile to increase the load-bearing capacity of the pile There is a unique The implantation of pipe fittings (15) at the top of the piles on both sides and connected by a pressure-resistant pipe (4) with a diameter? The inch is made of high density plastic (HDPE) connected to a pipe fitting (12) that is embedded in the tip of the top pile. And set the position of the pipe joints (12) in the same line with the pipe joints (6) embedded in the bottom of the pile head with the pile center pin. -------------------------------------------------- -------------- Let's hold the right to install a standard size 1/2 "pressure-resistant pipe with a coupling and mortar dispenser. Embedded in various precast concrete piles Even though it is a solid pile And piles with a central core in order to increase the load-bearing capacity of piles with cement grouting techniques
