Abstract
The invention discloses a round borehole hidden-rib anchor rod type supporting structure, which consists of supporting rib piles, a steel bar mesh and anchor rods. The supporting rib piles are round structures, steel bar frameworks are arranged inside the supporting rib piles, anchor rod holes are pre-arranged on pile bodies of the supporting rib piles, the steel bar mesh is fixed on the supporting rib piles through the anchor rods, and concrete is sprayed on the steel bar mesh. The round supporting rib piles are arranged at the pre-arranged hole positions of foundation pits, and the anchor rods are respectively and sequentially inserted into a soil layer behind the anchor rods when the pits are dug to the anchor rod hole positions, thereby forming the supporting structure step by step in the excavation process, shortening construction period of the supporting structure, saving construction costs, fully utilizing a high strength supporting structure formed by the supporting rib piles and the anchor rods, reducing deformation of a supporting structure system and guaranteeing safety of the foundation pits.
Description
Technical field
The present invention relates to a kind of the realm of building construction, is the dark rib anchor pole of a kind of circular borehole type supporting and protection structure specifically.
Background technology
In the foundation ditch construction of prevention work of the realm of building construction, extensively adopt the combined supporting structure of a steel mesh reinforcement and a circular rib pads stake at present; Its common construction, is carried out formwork construction a rib pads stake is installed after foundation ditch digs certain depth for carrying out the foundation ditch operation of digging pit earlier around foundation ditch; And in a rib pads stake, reserve bolthole; Anchor pole is inserted from bolthole in the soil layer at its rear after reaching design strength Deng a rib pads stake, fixedly mount steel mesh reinforcement in the rib pads stake propping up simultaneously, and on steel mesh reinforcement, spray concrete; To form one protection slab, prevent that foundation ditch from collapsing.But because this supporting and protection structure need be carried out formwork construction again after foundation ditch digs certain depth; Thereby its construction speed is slower; Simultaneously because himself intensity of the rib pads stake that formwork construction forms is relatively low, thus for ensure cross section that foundation ditch safety all can increase a rib pads stake to the greatest extent cun with the length of anchor pole, thereby can consume a large amount of concrete and reinforcing bar; Increase building costs, be unfavorable for creating conservation-minded society.
Summary of the invention
In order to solve the deficiency of prior art structure, the present invention provides the dark rib anchor pole of a kind of circular borehole type supporting and protection structure, not only can effectively play support action to foundation ditch, and speed of application is very fast, practices thrift the engineering construction cost.
The present invention realizes through following technical proposals: it props up rib pads stake, steel mesh reinforcement and anchor pole by circle and forms; Wherein propping up the rib pads stake is circular structure; Its inside is provided with cage of reinforcement, and on the pile body of a rib pads stake, is preset with bolthole, and steel mesh reinforcement is fixed in the rib pads stake through anchor pole; And on steel mesh reinforcement, be sprayed with concrete, wherein bolthole is horizontal by 30 ° ~ 35 ° angles.To prop up the rib pads stake among the present invention is circular structure, can improve himself intensity, reduces the structural system distortion; And then guarantee that a rib pads stake can reduce its sectional dimension bearing under the equally loaded situation; Reduce rock-bolt length simultaneously, before excavation of foundation pit, preset a rib pads stake, and skyhook successively; Make and in Excavation Process, just formed supporting and protection structure; Shortened construction period and practiced thrift construction costs, be utilized on the steel mesh reinforcement pneumatically placed concrete and make that a rib pads stake, steel mesh reinforcement and anchor pole are common to constitute the support system that rigidity is bigger, favourable guarantee foundation ditch safety.
The invention has the beneficial effects as follows: can not only play the good supporting effect to foundation ditch, and can reduce the distortion of structural system, in Excavation Process, progressively form supporting and protection structure simultaneously; Shortened construction period; Reduced the consumption of concrete and steel, practiced thrift cost of production, product structure is simple; Easy construction is convenient to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a main TV structure sketch map of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
Code description among the figure: 1 circular rib pads stake; 2 steel mesh reinforcements; 3 anchor poles; 4 boltholes; 5 beams.
The specific embodiment
Like Fig. 1, shown in Figure 2; The pile body that circle is propped up rib pads stake (1) is provided with bolthole (4); Steel mesh reinforcement (2) is fixed in the circular rib pads stake (2) through anchor pole (3), is provided with anchor pole (4) in the circular rib pads stake, has stronger resistance to tension in order to make anchor pole; Bolthole and horizontal plane are set to 30 ° ~ 35 ° angles, can make anchor pole horizontal by comparatively ideal tension angle with this.To prop up the rib pads stake among the present invention is circular structure; Can improve himself intensity; Reduce the distortion of supporting structure system, and then guarantee that a rib pads stake can reduce its sectional dimension bearing under the equally loaded situation, reduces rock-bolt length simultaneously; This just can practice thrift concrete amount and amount of reinforcement, thereby reaches the purpose of practicing thrift construction costs.And the present invention is employed in and presets a circular rib pads stake before the excavation of foundation pit; And skyhook successively, just make in Excavation Process, just progressively to have formed supporting and protection structure, shortened construction period; Also practiced thrift construction costs to a certain extent;, the degree of depth again steel mesh reinforcement is carried out the gunning concrete operation when reaching 2m, so that support system that rigidity is bigger of the common formation of a circular rib pads stake, steel mesh reinforcement and anchor pole, favourable guarantee foundation ditch safety.In the bigger foundation ditch of the degree of depth, for further increasing the stability of a circular rib pads stake, can prop up in circle and set up a beam (5) in the rib pads stake, so that all circular rib pads stakes are connected into an integral body, promote its support capacity.
Claims (2)
1. the dark rib anchor pole of circular borehole type supporting and protection structure; It is characterized in that: it is made up of a rib pads stake, steel mesh reinforcement and anchor pole; Wherein propping up the rib pads stake is circular structure, and its inside is provided with cage of reinforcement, and on the pile body of a rib pads stake, is preset with bolthole; Steel mesh reinforcement is fixed in the rib pads stake through anchor pole, and on steel mesh reinforcement, is sprayed with concrete.
2. the dark rib anchor pole of a kind of circular borehole according to claim 1 type supporting and protection structure, it is characterized in that: bolthole is horizontal by 30 ° ~ 35 ° angles.
