JP-3255773-U - Geotechnical injection device

Abstract

[Problem] To provide a geotechnical injection device that has automatic height adjustment and vibration-preventing positioning functions, can be operated independently, reduces the intensity of construction work, and is suitable for use in complex geotechnical construction sites. [Solution] The device comprises a base plate 1 and a storage tank 2 provided above it. Self-locking casters 3 are provided at the four corners of the lower end surface of the base plate, vertical columns 5 are provided on both sides of the storage tank, and sliding grooves and sliders are provided on the opposing surfaces of the vertical columns. A first drive mechanism drives the sliders to adjust the height of the storage tank. A movable rod 8 is slidably connected to the outside of the vertical columns, and a swing plate 12 is hinged to the vertical columns. A second drive mechanism swings the swing plate, causing the movable rod to slide downward via the cooperation of an arc-shaped transmission block 15 and a transmission plate 9, and a support plate 10 performs vibration-preventive positioning of the device. A power box 16 and a control device are provided on the base plate to achieve centralized control of each electric component. The purpose is to solve the problems of conventional injection devices, which have poor construction suitability because the storage tank height cannot be adjusted, are prone to misalignment due to vibration, and require force for manual positioning.

Description

This invention relates to the field of geotechnical engineering construction equipment technology, and more particularly to injection devices for geotechnical engineering. Injection is a core construction method in geotechnical engineering for ground reinforcement, crack sealing, and slope disease treatment. By pressurizing and injecting pre-mixed injection slurry into voids and cracks in the ground and rock mass, the density, strength, and watertightness of the ground and rock mass are improved, and it is widely applied in geotechnical engineering construction such as foundation pile construction, roadbed reinforcement, and tunnel waterproofing. The injection equipment is the core equipment of injection construction, and its ease of operation, stability of slurry delivery, and suitability for construction affect the efficiency and quality of direct injection construction. Currently, most general-purpose injection devices used in geotechnical engineering are fixed or simply movable, and many compatibility and operational problems become apparent during actual construction processes, failing to meet the needs of complex geotechnical construction sites. Firstly, the storage tanks of general-purpose injection devices are often fixed-height designs, making it impossible to flexibly adjust the discharge height of the discharge pipe according to the required height at the injection site and the location of the injection hole. Secondly, vibrations occur during the injection process, making the injection device prone to displacement. However, positioning of existing injection devices largely relies on manual adjustment, resulting in extremely low positioning efficiency, and the heavy weight of the device requires considerable force during positioning. Therefore, the inventors propose a geotechnical injection device to solve these problems.
