The present application relates to a kind of lime-soil compaction pile construction system for collapsible loess area, before construction, good technology, material, equipment and site preparation, such as familiar drawing, prepare soil and lime, debug hole and ramming equipment, level site and surveying and setting out etc..During construction, first carry out test pile to determine parameters, large-scale hole formation follows specific sequence and strictly controls pile diameter, perpendicularity etc.;Pile formation first clean bottom ram, then layered packing ramming, accurate operation by control system;After pile formation, do well maintenance.Quality detection uses low-strain dynamic penetration method to detect pile integrity, plate load test to detect composite foundation bearing capacity.The method is applied to a certain commercial complex project, construction is smooth, hole formation and pile formation quality meet the standards, efficiency is improved, construction period is shortened.

The present application relates to a kind of steep bare rock area water drilling floating self-stabilizing platform and its installation method, drilling floating self-stabilizing platform includes platform structure, anchoring structure and positioning structure, the platform structure is used for the load bearing of drilling equipment, the anchoring structure is used for the plane positioning and movement of platform structure, the positioning structure is used for the fixed connection of platform structure and rock bank slope, the platform structure includes hull and drilling platform cornice, the drilling platform cornice is fixedly arranged in the side of hull, the anchoring structure includes outer eight character anchor and inner eight character anchor, the outer eight character anchor is arranged in the side of hull away from rock bank, the present application can guarantee that hull is located in a stable plane position, hull is under the constraint of slide groove, can be moved up and down along the slide on positioning pile, effectively adapt to the fluctuation of water level.

This invention discloses a cleaning device for tile bonding surfaces, relating to the field of tile cleaning technology. This invention addresses the shortcomings of existing technologies, which cannot comprehensively clean the gaps and sidewalls of tile bonding surfaces on walls, and suffer from problems such as high probability of glaze damage and incomplete cleaning. On one hand, through the coordinated operation of the walking positioning module and the grout cleaning execution component, it achieves refined cleaning and interface activation of the entire depth and surface of the tile bonding surface, thoroughly removing various impurities that affect the adhesion performance of the grout. On the other hand, through a directional closed dust suction module, it achieves source control and real-time collection of grout cleaning dust, preventing the spread of dust during operation and optimizing the construction environment. An angle-adjustable adsorption and fixing module enables stable self-fixation of the device in various scenarios such as walls and corners, eliminating the need for continuous manual support, significantly reducing work intensity, and broadening the applicable scenarios of the device.

This invention provides a method for constructing a pile-type crane base, comprising the following steps: constructing a flat outer shell plate and marking a first installation reference line on the flat outer shell plate; prefabricating multiple independent arc-shaped plates according to the layout of the entire arc-shaped outer shell plate, wherein the arc-shaped plates have processing allowances during material cutting; prefabricating a top ring component and marking a second installation reference line on the top ring component; constructing a main frame and setting a central column at the center of the main frame; hoisting multiple flat outer shells and the top ring component onto the main frame respectively, adjusting their positions, and welding them after meeting the accuracy requirements; hoisting and positioning multiple vertical reinforcing ribs according to the first and second installation reference lines; hoisting the arc-shaped plates in sequence, cutting processing allowances, adjusting accuracy, and then welding multiple arc-shaped plates in a preset sequence to form an arc-shaped outer shell plate; welding the arc-shaped outer shell plate, horizontal structure, and vertical reinforcing ribs; and welding the arc-shaped outer shell plate and the flat outer shell plate.
