Manufacturer of anti-floating anchors for foundation pits with skeleton bladder-type expanded anchors

Skeleton-type expanded anchors
Skeleton-type expanded anchors
This patented product, skeleton-type expanded anchors, adopts a high-strength civil engineering cloth capsule design. The cement slurry is pumped through a high-pressure pump. Injected into the bladder, the surrounding soil is squeezed during the grouting process of the bladder to form a cement consolidation body in the expanded section. Pressurized filling in the bladder can fully ensure that the shape of the consolidation body is uniform and dense, and a single anchor can carry large load tension.
This product adopts an integrated design and has a high degree of intensification. It can be assembled directly after arriving at the construction site, making construction convenient and fast. Due to the pressurized pouring method, this product can solidify quickly and can be tensioned in a short time. The construction quality is reliable. It also has the characteristics of high anchor bearing capacity, short anchor length, and small number of anchors. It has significant economic and environmental benefits. improve.

Quality control of grouting stone body The compressive strength of the stone body is less than that of the stone body, and it is easy to contain mud and the pores are unevenly distributed. The compressive strength of the stone body is greater than 3, and pressurized perfusion of the bag can ensure that the stone body is uniform and dense.
The construction quality of the anchor bundle body and the anti-corrosion tension type anchor are not conducive to long-term anti-corrosion. The anchor bundle body is not easy to center and the reinforcement is easy to corrode. The pressure-type anchor has reasonable stress, which is conducive to the anti-corrosion of the anchor. The anchor bundle body is centered and protected by multiple protection and anti-corrosion technologies.
Construction efficiency and construction period Anchors need to be made on site, the grouting setting time is long, and the tension locking construction is slow. The anchoring sections are made in the factory and are directly assembled into expanded anchors after being transported to the construction site. The specially formulated expansion material solidifies quickly and can be tensioned in a short time.
Economic and environmentally friendly features: It is difficult to control the construction quality. There are many anchor rods, the rod body is long, and the bearing capacity of a single anchor is low. The construction quality is reliable, the single anchor bearing capacity is high, the length is short, the quantity is small, and the economic and environmental benefits are high.
Anchor technology is widely used in high-rise buildings, rail transit, bridge and tunnel engineering, urban underground transportation hubs, ports and terminals, high reservoir dams, slope engineering, mine construction, national defense engineering and other fields. The engineering community is facing a large number of Tunnels, underground caverns, well port support, slope stabilization, deep foundation pits, structural anti-floating, large-scale high-pressure water pipelines, geotechnical engineering stability issues with high technical difficulty and risk. Expanded anchoring technology is one of the ways to ensure the safety, economy, efficiency and environmental protection of the above-mentioned project construction.
Application fields of bladder-type expanded anchors with skeleton
Blanket-type expanded anchors with skeleton belong to the field of civil engineering technology and are suitable for high-rise buildings, rail transit, bridge and tunnel projects, urban underground transportation, and interchanges Foundation reinforcement in hubs, ports, high reservoir dams, slope projects, mine construction, national defense projects and other fields. It adopts a bladder-type integrated design, and forms an anchoring enlarged head after grouting. It is made of high-strength precision-rolled rebar through the guide rod, fixed on the bottom steel chuck by a special nut and a pallet locking device. After the skeletonized bladder-type expanded anchor is sent into the ground, it is injected with high pressure. The anchoring balloon expands and expands to form a large-diameter, high-strength anchor until it is tight, thereby achieving integrated hole sealing and anchoring.
