At present, in the building construction process, particularly in the rock reinforcement and underground cavern grouting construction process, an advance anchor rod needs to be additionally arranged according to the geological conditions of different sections, and the anchor rod needs to be reinforced necessarily, so that the operation safety and stability are improved.
Among the prior art, installing the stock, especially the in-process of the anchor rod hole is under construction to the sky of elevation stock and underground cavern crown, adopt the mode of inserting the stock after slip casting earlier mostly, this operating mode leads to the stock to insert the process resistance great easily, and the construction degree of difficulty increases, and when carrying out the insertion of elevation stock, makes the mortar take place because of the phenomenon that the dead weight leads to the downflow easily, has certain potential safety hazard.
In addition, the anchor rod is inserted firstly and then grouting is carried out, the exhaust pipe is arranged on the anchor rod body, and redundant gas in the anchor rod hole in the grouting process is discharged through the exhaust pipe, so that the grouting process is more convenient and safer, and the operation is convenient and fast. However, the exhaust pipe is arranged on the anchor rod body, so that the bonding stress between mortar and the anchor rod can be influenced, the more the exhaust pipes are arranged, the less the mortar is injected into the anchor rod hole, and the stability is weakened.
Therefore, in order to solve the in-process of constructing the anchor rod hole towards the sky of elevation anchor rod and underground cavern crown among the prior art, the blast pipe can influence the bonding stress between mortar and the anchor rod and the technical problem of bonding steadiness with the mode that sets up of anchor rod, this application proposes a solution, specifically as follows:
in one embodiment, as shown in fig. 1, fig. 1 is a schematic view of an elevation mortar anchor structure according to one embodiment.
The application provides an elevation mortar stock, as shown in fig. 1, it includes: the anchor rod body 1 and the exhaust pipe 3 are positioned above the anchor rod body 1 and are attached to the inner wall of the construction anchor hole 2, and a grout stop plug 4 is arranged at the orifice of the construction anchor hole 2; the stock body of rod 1 with the one end of blast pipe 3 is all passed through it is fixed to end thick liquid stopper 4, the below of the stock body of rod 1 is passed through it installs slip casting pipe 5 to end thick liquid stopper 4.
It can be understood that, the blast pipe 3 here sets up in the inner wall top of construction anchor eye 2, and forms certain interval between the stock body of rod 1, when pouring into mortar into its inside through construction anchor eye 2, the tip that blast pipe 3 is located 2 inner chambers of construction anchor eye absorbs the gas of blast pipe 3 because the injection flow of mortar flows through in construction anchor eye 2 to reduce 2 inner chambers of construction anchor eye because of gaseous unable in time discharge, lead to mortar injection speed slower, influence the construction progress.
In addition, set up the blast pipe 3 in the top of the stock body of rod 1, with the laminating of 2 inner walls in construction anchor eye, neither can influence the bonding stress between mortar and the stock, also can not reduce the mortar injection volume in the construction anchor eye 2, be favorable to improving the steadiness of the stock body of rod 1 in construction anchor eye 2.
A grout stop plug 4 is arranged at the orifice of the construction anchor hole 2; the anchor rod body 1 and one end of the exhaust pipe 3 are fixed through the grout stop plug 4.
In this application, because construction anchor eye 2 is the elevation angle anchor eye or towards the sky hole, therefore at the in-process of construction, in order to prevent the mortar refluence, can set up the grout stopping plug 4 that matches with construction anchor eye 2 in the drill way department of construction anchor eye 2, grout stopping plug 4 can stop up the entrance to a cave of construction anchor eye 2 completely, avoids the mortar to flow out.
In addition, because the anchor rod body 1 inserts construction anchor eye 2 and carries out the in-process that the mortar is firm, can receive the influence of the mortar of pouring into to produce and rock, therefore, when construction anchor eye 2 drill way department sets up and ends thick liquid stopper 4, can be located the anchor rod body 1 and end thick liquid stopper 4 one end rather than fixing, and in the same way, the blast pipe 3 is located and ends thick liquid stopper 4 one end and also fixes rather than, makes things convenient for the construction operation.
The grout stop 4 is a plug structure capable of bearing the weight of the anchor rod body 1 and the grout filling the construction anchor hole 2.
And, in this application, the below of the stock body of rod 1 is passed through only grout stopper 4 installs slip casting pipe 5, and slip casting pipe 5 can be used to be connected with the grouting pump to pour into the slip casting into construction anchor eye 2.
In one embodiment, referring to fig. 1, one end of the anchor rod body 1 is fixed to the middle of the construction anchor hole 2 through the grout stop plug 4.
In this embodiment, the anchor rod body 1 is fixed to the middle of the hole site of the construction anchor hole 2 in consideration of convenience of later construction work and working conditions of the exhaust pipe 3 and the like when mortar is injected.
In one embodiment, the grout pipe 5 is located between the inner wall of the construction anchor hole 2 and the bolt body 1.
In this embodiment, be fixed in between the inner wall of construction anchor eye 2 and the stock body of rod 1 with slip casting pipe 5, mainly be in order to provide the slip casting through slip casting pipe 5 outside, can also be in the slip casting, the air of squeezing is arranged when absorbing below slip casting pipe 5 injection thick liquids through blast pipe 3 of stock body of rod 1 top for the gas in the construction anchor eye 2 can in time be discharged, improves the operating efficiency.
In one embodiment, there are at least two sets of the grouting pipes 5, and the two sets of the grouting pipes 5 are arranged in parallel.
It can be understood that there are at least two groups of grouting pipes 5, and two groups of grouting pipes 5 are arranged side by side, and may be located on the same horizontal line or the same vertical line, and the two groups of grouting pipes 5 operate simultaneously, which is beneficial to improving the operating efficiency.
In one embodiment, two sets of the grouting pipes 5 arranged side by side are positioned on the same horizontal line in the construction anchor hole 2.
In this embodiment, two sets of grouting pipes 5 arranged in parallel are installed on the same horizontal line on the grout stop plug 4, so that the radial space of the construction anchor hole 2 can be saved, and the working efficiency can be improved.
In one embodiment, one end of the anchor rod body 1 in the construction anchor hole 2 is fixed with the inner wall of the construction anchor hole 2 through the anchor rod anti-deviation steel bar 7 welded with the anchor rod body, so that the anchor rod body 1 is more stable during construction operation.
In one embodiment, the end of the exhaust pipe 3 in the construction anchor hole 2 is a slope to increase the absorption area and improve the operation efficiency.
In one embodiment, an exhaust inspection device 6 is connected to one end of the exhaust pipe 3 located outside the construction anchor hole 2, and when slurry is doped in the gas exhausted from the exhaust pipe 3, the slurry in the construction anchor hole 2 is full, and grouting is completed.
In addition, the exhaust pipe 3 must be inserted into the bottom of the construction anchor hole 2 so that whether to stop grouting can be judged by whether or not grout is removed from the exhaust pipe 3.
To sum up, this application adopts the grouting pump to carry out the slip casting construction to the construction anchor eye at the in-process of the anchor eye of constructing towards the sky that carries out elevation anchor rod and underground cavern crown arch, and the blast pipe is from opposite side exhaust gas, neither can influence the bonding stress between mortar and the anchor rod, also can not reduce the mortar injection volume in the construction anchor eye, is favorable to improving the stock body of rod in the stability of construction anchor eye.
