Abstract
The utility model discloses a slope bracing structure of a large-span foundation pit or foundation trench, which can greatly reduce the construction cost of the slope bracing structure of the foundation pit or the foundation trench, and comprises a slope soil body and filling concrete covering on a slope, wherein the filling concrete and the slope soil body are fastened by an anchor rod; an anchor section of the anchor rod is positioned in the slope soil body, and a free section thereof is positioned in the filling concrete; the free section of the anchor rod is provided with a supporting body which comprises a steel bar barricade connected with the anchor rod, and an L-shaped steel bar fixing frame connected with the anchor rod; the free ends of the two adjacent anchor rods are connected by longitudinal connecting steel bars 7 which are two in number; and a concrete anchoring agent of the anchoring section is microdilatancy cement. The slope bracing structure effectively prevents the dip slip of the filling concrete, has high construction efficiency, saves construction cost and is especially applicable to the slope bracing of the large-span foundation pit or foundation trench.
Description
Technical field
The utility model relates to building field, relates in particular to a kind of big span foundation ditch or foundation trench slope retaining structure.
Background technology
In industry and civilian construction, often need to lay such as underground structures such as cable tunnel, waste water vestibule, Equipment Foundations, this just needs excavation pit or foundation trench, influence construction speed and personal security for preventing the distortion of foundation ditch or foundation trench slope soil or tumbling, side slope is typically provided with the safe construction that filling concrete sliding masses guarantees structure in foundation ditch or the foundation trench.But in the frictional force of slope soil and concrete sliding masses hour, the concrete sliding masses on the side slope also produces slippage even topples over along side slope easily, has a strong impact on safety of construction in foundation ditch or the foundation trench.At present, in the foundation ditch or the work of foundation trench slope retaining of big span, the reinforcement measure of concrete sliding masses is generally in the concrete sliding masses inboard reinforced bar support frame is set, as shown in Figure 1, need on the filling concrete, built-in fitting be set, squeeze into the bar reinforcement earth anchor in foundation trench bottom, as support, and need according to circumstances the bracing frame that does not highly wait is set in a plurality of positions with shaped steel, these reinforcing bars, shaped steel all can't reclaim after finishing construction, the material cost height of this method, the cycle is longer, and is time-consuming.
The utility model content
The technical problem that the utility model solved is, provides that a kind of cost is low, the big span foundation ditch of easy construction or foundation trench slope retaining structure.
The technical solution adopted in the utility model is, big span foundation ditch or foundation trench slope retaining structure comprise slope soil, are covered in the filling concrete on the side slope, and filling concrete and slope soil are fastening with anchor pole, the anchoring section of anchor pole is arranged in slope soil, and the free section of anchor pole is arranged in fills concrete.
The free section of described anchor pole is provided with supporter.
Described supporter comprises the reinforcing bar split heads that is connected with anchor pole.
Described supporter comprises the L shaped reinforcing bar fixed mount that is connected with anchor pole.
Be connected with vertical connecting reinforcement 7 between the free end of adjacent two anchor poles.
Vertically connecting reinforcement is two,
The cement anchoring agent of described anchoring section is a micro-expansion cement.
The beneficial effects of the utility model are, effectively prevent to fill the cunning of inclining of concrete, and the efficiency of construction height has been saved construction cost.

Be labeled as among the figure: the 1-slope soil, 2-fills concrete, 3-anchor pole, 5-reinforcing bar split heads, 6-reinforcing bar fixed mount, the vertical connecting reinforcement of 7-, 8-cement anchoring agent.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Big span foundation ditch of the present utility model or foundation trench slope retaining structure, comprise slope soil 1, be covered in the filling concrete 2 on the side slope, it is fastening with anchor pole 3 with slope soil 1 to fill concrete 2, and the anchoring section of anchor pole 3 is arranged in slope soil 1, and the free section of anchor pole 3 is arranged in fills concrete 2.As shown in Figure 2, anchor pole 3 will be filled concrete 2 and will be connected as a single entity with slope soil 1, effectively prevent to fill the landing of concrete 2 or topple over, and ensure the smooth and safety of construction.
After excavation slope, needs according to field condition are holed on slope soil 1, insert anchor pole 3 then, in the hole, inject cement anchoring agent 8, fixing anchor bar 3 props up the filling concrete form then, builds and fills concrete 2, so just finished the construction of big span foundation ditch or foundation trench slope retaining structure, removed the filling concrete form then and can carry out structure construction in foundation ditch or the foundation trench.Wherein anchor pole 3 insertion depths can calculate as the case may be, are generally about 10 meters, if adopt anchor cable, then to be generally be about 15 meters to insertion depth, and the insertion angle of anchor pole 3 also draws as calculated according to concrete field condition difference.The interval of adjacent anchor pole 3 is generally about 3 meters.The utility model has adopted lower-cost anchor pole 3 or anchor cable to carry out slope retaining, for big span slope retaining structure construction, with respect to the slope retaining structure that needed a large amount of reinforcing bars, earth anchor, shaped steel to support in the past, construction materials cost significantly reduces, and the efficiency of construction height helps advancing the progress of whole engineering.
The free section of described anchor pole 3 is provided with supporter.Finish in the hole of slope soil 1 inject cement anchoring agent 8 after, supporter is installed.As shown in Figure 3, supporter plays support, reinforcement effect to anchor pole 3, builds that the free section to anchor pole supports, protects in the process filling concrete 2, and anchor pole 3 is better combined with filling concrete 2.Simultaneously, fill concrete 2 and build the back supporter that finishes and also be combined as a whole, and supporter also is connected with anchor pole 3, increased anchor pole 3 and filled the steadiness of the combination of concrete 2, make filling concrete 2 be connected more firm with slope soil 1 with filling concrete 2.Described supporter comprises the reinforcing bar split heads 5 that is connected with anchor pole 3.Reinforcing bar split heads 5 can adopt common a few font split heads, and reinforcing bar split heads 5 can also can bundle with rope for welding with the connected mode of anchor pole 3.As another embodiment of the utility model, described supporter comprises the L shaped reinforcing bar fixed mount 6 that is connected with anchor pole 3.Reinforcing bar fixed mount 6 can be weldingly connected with anchor pole 3, also can be by binding.Above-mentioned embodiment can independently separately be implemented also can implement simultaneously, simultaneously the better effects if of Shi Shiing.
Be connected with vertical connecting reinforcement 7 between the free end of adjacent two anchor poles 3.After the installation of the supporter of finishing anchor pole 3, carry out the installation of vertical connecting reinforcement 7, as shown in Figure 4, vertically adjacent anchor pole 3 is welded or is bundled at the two ends of connecting reinforcement 7 respectively, vertical connecting reinforcement 7 between a plurality of anchor poles 3 just constitutes the net structure of a plurality of tie points, after filling concrete 2 was built and finished, netted a plurality of vertical connecting reinforcement 7 and the anchor pole 3 that links to each other thereof just were combined as a whole with filling concrete 2, made 3 pairs of carryings of filling concrete 2 of anchor pole more firm.
The cement anchoring agent 8 of described anchoring section is a micro-expansion cement.Use micro-expansion cement can strengthen the bonding rubbing action of anchor pole 3 and slope soil 1, obtain better anchoring effect.
