Abstract

The utility model relates to a construction technical field, concretely relates to steel casing pipe pore -forming anti -floating anchor rod. It includes the anchor eye by pipe diameter 180mm's steel casing pipe aided forming, the anchor eye degree of depth is greater than construction ground soil layer thickness, anchor eye aperture deviation is less than 20mm, set up the steel casing pipe in the anchor eye, set up the stock in the steel casing pipe, the interval sets up a plurality of locating supports on the stock, cement mortar is poured into into in the slip casting of anchor eye internal pressure, anchor eye upper portion port sets up the stagnant water steel sheet. Through the steel casing pipe pore -forming, ensure that anti -floating anchor rod passes through silt dirt bed or szyrt layer smoothly, high -pressure slip casting in the steel casing pipe, the drilling rod around with remain mountain flour, the sand formation anchoring body at the hole bottom, guarantee the anchor requirement, effectively solved the hole problem of collapsing, ensure the anchor power of stock and soil layer, the construction is simple and convenient and comparatively saves time, the steel casing pipe is for the self -control shaping and can use repeatedly.

Description

A kind of steel thimble pore-forming anti-float anchor rod
Technical field
This utility model is related to technical field of building construction and in particular to a kind of steel thimble pore-forming anti-float anchor rod.
Background technology
It is miscellaneous fill layer, mud, farinose argillic horizon, medium-sand seam, gravel layer etc. for top, bottom is stable wind Change the area of rock, because some areas level of ground water is higher, in addition to setting pile foundation etc. increases stability of foundation, building structure Generally setting anti-float anchor rod is in order to solve the problems, such as building anti-floating.Because soil property is complicated, during anchor pole pore-forming because run into mud, clay or The phenomenons such as quicksand that layer of sand is formed under the outer differential water pressures of in the hole drive and cause collapse hole phenomenon, lead to pore-forming difficulty to increase it is impossible to Ensure grouting quality, thus being difficult to ensure that the design withdrawal resistance of anti-float anchor rod.
Utility model content
For deficiency present on prior art, this utility model provides a kind of steel thimble slip casting pore-forming, solution collapse hole to ask Topic, and operate convenient, simple steel thimble pore-forming anti-float anchor rod of constructing.
To achieve these goals, this utility model is to realize by the following technical solutions:
A kind of steel thimble pore-forming anti-float anchor rod, it is included by the anchor hole of the steel thimble assistant formation of caliber 180mm, described anchor Hole depth is more than construction ground soil thickness, and described anchor hole Aperture deviation is less than setting steel thimble, described steel in 20mm, described anchor hole Setting anchor pole in sleeve pipe, some locating supports of interval setting on described anchor pole, slip casing by pressure injection cement mortar in described anchor hole, Described anchor hole upper port arranges steel plate for sealing water.
A kind of above-mentioned steel thimble pore-forming anti-float anchor rod, its described anchor hole perpendicularity deviation is less than 1.5%.
A kind of above-mentioned steel thimble pore-forming anti-float anchor rod, the spacing of its described locating support is 2m.
A kind of above-mentioned steel thimble pore-forming anti-float anchor rod, its described cement mortar includes intensity and is more than 42.5Mpa, the ratio of mud 0.45 ~ 0.5 portland cement, particle diameter is less than the fine sand that 2mm, clay content are less than 3% by weight.
Beneficial effect:
This utility model passes through steel thimble pore-forming it is ensured that anti-float anchor rod smoothly passes through soft mud or drifting sand layer, steel bushing Pipe inner high voltage slip casting, around drilling rod with remain in the stone powder of bottom hole, sand forms anchoring body it is ensured that anchoring requires, effectively solving Collapse hole problem it is ensured that the anchor force of anchor pole and soil layer, easy construction and more save time, steel thimble is self-control molding and can be repeatedly Use.
Brief description
To describe this utility model with reference to the accompanying drawings and detailed description in detail;
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Technological means, creation characteristic, reached purpose and effect for making this utility model realize are easy to understand, below In conjunction with specific embodiment, this utility model is expanded on further.
With reference to Fig. 1, this utility model includes by the anchor hole 2 of steel thimble 1 assistant formation of caliber 180mm, and anchor hole 2 depth is big In construction ground soil thickness, anchor hole 2 Aperture deviation is less than 20mm, and perpendicularity deviation is less than 1.5%, setting steel thimble 1 in anchor hole 2, Setting anchor pole 3 in steel thimble 1, interval 2m welding on anchor pole 3 arranges some 3 Φ 6(HRB400)Locating support 4, anchor hole 2 is intrinsic pressure Cement mortar 5 is injected in power slip casting, and cement mortar 5 includes intensity and is more than 42.5Mpa, the portland cement of the ratio of mud 0.45 ~ 0.5, Particle diameter is less than the fine sand that 2mm, clay content are less than 3% by weight.Anchor hole 2 upper port arranges steel plate for sealing water 6.
This utility model passes through steel thimble pore-forming it is ensured that anti-float anchor rod smoothly passes through soft mud or drifting sand layer, steel bushing Pipe inner high voltage slip casting, around drilling rod with remain in the stone powder of bottom hole, sand forms anchoring body it is ensured that anchoring requires, effectively solving Collapse hole problem it is ensured that the anchor force of anchor pole and soil layer, easy construction and more save time, steel thimble is self-control molding and can be repeatedly Use.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have been shown and described above.One's own profession The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also Have various changes and modifications, these changes and improvements both fall within the range of claimed this utility model.This utility model Claimed scope is by appending claims and its equivalent thereof.
