Embodiment 1

[0041] combine Figure 1 to Figure 2 As shown, the first embodiment provides a combined reinforced uplift anchor device, which includes: a concrete prefabricated pile body 4, a positioning bracket 3, a core tube 10 and several bars 8; the concrete prefabricated pile body 4 is provided with an upper end Plate 7 and lower end plate 9; the positioning bracket 3 is a cross centering bracket, a positioning hole (for installing the core pipe 10) is formed in the center of the positioning bracket 3, one of the positioning brackets 3 is fixed to the upper end plate 7 of the concrete prefabricated pile 4 The lower surface of the concrete prefabricated pile body 4 (inside the concrete prefabricated pile body 4), another positioning bracket 3 is fixed on the upper surface of the lower end plate 9 of the concrete prefabricated pile body 4 (located inside the concrete prefabricated pile body 4); Installed in the positioning hole of the positioning bracket 3 at the lower end plate 9, the up...

Embodiment 2

[0050] The second embodiment also provides a construction method for the combined reinforced anti-pull anchor device according to the first embodiment, which includes the following steps:

[0051] S1. Reasonably configure the length of the precast concrete piles according to the calculated bearing capacity, preferably single-section precast piles, and fix the positioning brackets 3 (precast concrete piles 4) on the upper end plate 7 and the lower end plate 9 of each section of the concrete precast pile The upper end plate 7 and the lower end plate 9 are respectively welded or bonded to the positioning bracket 3), and the core tube 10 is placed in the positioning hole of the positioning bracket 3 (the core tube 10 is a rigid plastic tube or a welded steel pipe for low-pressure fluid transportation), The bottom of the concrete prefabricated pile body 4 is sealed with cement mortar or bean stone concrete (to form a pile bottom seal 6), and waterproof and anti-corrosion treatment i...

Abstract

The invention relates to the technical field of buildings, in particular to a combined reinforced anti-pull anchor rod device and a construction method thereof. The combined reinforced anti-pull anchor rod device can be widely applied to floating resisting of buildings (structures), comprehensive pipe galleries and underground construction foundations, and can also be applied to foundation pit andside slope supporting engineering. According to the combined reinforced anti-pull anchor rod device, positioning supports are fixed to an upper end plate and a lower end plate of a concrete precast pile correspondingly, core pipes are arranged on positioning holes of the positioning supports, and a plurality of rod ribs are arranged in the core pipes; the concrete precast pile is constructed through a static pressure or hammering method, zero emission is achieved in the construction process, a concrete pile body and a composite anchoring body are stable and reliable in quality, high in construction efficiency and convenient to operate, the single anti-pull bearing capacity is high, on-site passing is convenient, and the comprehensive cost is reduced; the concrete precast pile is a bearingbody of a composite anchor rod and is also a protection layer of the rod rib, the rod rib can be effectively protected from being corroded by a corrosive medium in underground water and soil, dan thedurability of the anchoring body is improved; and the rod rib can be stretched to exert prestress.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a combined reinforced anti-pulling anchor rod device and a construction method, which can be widely used in construction (structure) buildings, integrated pipe galleries, and underground engineering foundation anti-floating, and can also be applied to foundation Pit and slope support works. Background technique [0002] In recent years, with the rapid development of urban construction, the depth of building foundations has continued to increase, and the problem of anti-floating has become more and more prominent. At present, the main measures to solve the problem of anti-floating of the foundation of underground structures are the method of releasing water buoyancy, adding the method of counterweight, and setting up anti-floating members such as uplift piles or anti-floating anchors. Among them, setting uplift-resistant piles and anti-floating anchors and other anti-floatin...
