Description
Technical Field
The utility model relates to a cap grouting device, and belongs to the technical field of buildings.
Background
When the traditional rock-soil anchoring grouting device is used for grouting, an anchoring rod body and a grouting pipe are implanted into a borehole or a hole-forming sleeve which is formed in advance, cement slurry is injected through the grouting pipe, the cement slurry is injected into the borehole or the sleeve from a slurry outlet at the bottom of the grouting pipe until slurry returns in the orifice or the sleeve, and then the sleeve is pulled out or grouting is directly completed.
When the traditional grouting device is used for grouting soft rock or soil stratum, mud skin adhered to the hole wall cannot be effectively removed, so that the bonding strength between the anchor bodies in the soft rock and the soil stratum and the hole wall is low, and even the risk of hole collapse possibly exists. The detection result of engineering implementation shows that when the traditional grouting device is adopted for grouting, the anchor cable and the anchor rod of the traditional grouting have smaller general anchoring force and obvious creep effect, and the quality of the anchoring body is also poor.
Disclosure of Invention
In view of the above, in order to solve the technical problem that the quality of the anchoring body after grouting by the grouting device in the prior art is poor, the utility model aims to provide a cap grouting device, slurry which is grouting by the grouting device cannot return to slurry through the top of a sleeve, but overflows through the outer side of the sleeve through the bottom of the sleeve, and as the gap between the grouting device and the hole wall is smaller, certain pressure can be formed on the overflowed grouting slurry, mud skin between the sleeve and the hole wall in the grouting device can be effectively replaced, the bonding strength of the anchoring body and the hole wall can be effectively improved, the anchoring quality of the anchoring body can be improved, and the pulling resistance of an anchor rod or an anchor rope can be effectively improved.
In order to achieve the purpose of the utility model, the following technical scheme is provided.
A cap grouting device comprises a cap, a sleeve, a handle and a grouting opening;
the bottom of the cap is detachably connected with one end of the sleeve, the top of the cap is provided with a grouting opening, and slurry is injected into the sleeve through the grouting opening to finish grouting;
when the sleeve is connected with the cap, the setting of the cap can effectively avoid slurry injected into the sleeve from returning slurry from the sleeve, but the slurry overflows through the other end of the sleeve, so that the bottom of the sleeve returns slurry through the outer side of the sleeve.
Further, the inner surface of the bottom of the cap is in threaded connection with the outer surface of one end of the sleeve.
Further, a handle is provided outside the sidewall of the cap.
Further, the shape of the handle is linear.
Further, the number of the handles is two, and the handles are symmetrically distributed outside the side wall of the cap.
Advantageous effects
(1) The utility model provides a cap grouting device, which can effectively protect the stability of the wall of a grouting hole and prevent the wall of the hole from collapsing. Because the slurry injected by the grouting device can not return slurry through the top of the sleeve, but overflow through the bottom of the sleeve and the outside of the sleeve, a certain pressure can be formed on the overflowed grouting slurry due to the smaller gap between the grouting device and the hole wall, mud skin between the sleeve and the hole wall in the grouting device can be effectively replaced, the bonding strength of an anchoring body and the hole wall can be effectively improved, the anchoring quality of the anchoring body can be improved, and the pulling resistance of an anchor rod or an anchor rope can be effectively improved. By grouting through the grouting device, the construction qualification rate of the soft rock, the soil layer anchor rod or the anchor cable can be more than 50%, the pulling resistance of the soft rock, the soil layer anchor rod or the anchor cable can be improved by more than 30%, and the manufacturing cost can be reduced by about 20%.
(2) The utility model provides a cap grouting device, which is provided with a handle, so that the cap and a sleeve are convenient to connect, fasten and detach, and the sleeve can be rotated in the grouting process through the connection of the handle and the sleeve, so that the effect of removing the pore wall mud skin is improved.
(3) The utility model provides a cap grouting device, wherein the shape of a handle is linear, the number of the handles is two, and the handles are symmetrically distributed outside the side wall of a cap, so that the operation is convenient.

Detailed Description
The utility model is further described below with reference to the drawings and the detailed description.
Example 1
As shown in fig. 1-3, a cap grouting device comprises a cap 1, a sleeve 2, a handle 3 and a grouting opening 4;
the bottom of the cap 1 is detachably connected with one end of the sleeve 2, a grouting opening 4 is formed in the top of the cap 1, and slurry is injected into the sleeve 2 through the grouting opening 4 to finish grouting; when the sleeve 2 is connected with the cap 1, the cap 1 can effectively prevent slurry injected into the sleeve 2 from returning from the sleeve 2, but the slurry overflows through the other end of the sleeve 2 (namely, the bottom of the sleeve 2), so that the bottom of the sleeve 2 returns from the outside of the sleeve 2.
The outside handle 3 that is provided with of lateral wall of block 1 is convenient for block 1 and sleeve pipe 2 be connected, fastening and dismantlement to the accessible handle 3 is connected with sleeve pipe 2, can implement the rotation to sleeve pipe 2 at slip casting in-process, improves the effect of getting rid of the pore wall mud skin.
The sleeve 2 in the grouting device can be used as a device for protecting the hole wall and can finish grouting, and the sleeve 2 can be a sleeve while drilling by a drilling machine. When the sleeve 2 is connected with the cap 1, the top end of the sleeve 2 is closed by the cap 1, so that the slurry injected into the sleeve 2 through the grouting opening 4 can only flow out through the bottom of the sleeve 2 and return to the slurry through the outer side of the sleeve 2; because the clearance between the sleeve 2 and the hole wall is smaller, the overflowed grouting slurry can form certain pressure, mud skin between the sleeve 2 and the hole wall can be effectively replaced, the bonding strength of the grouting body and soil body is improved, the quality of an anchoring body is improved, the pulling resistance of an anchor rod and an anchor cable is further effectively improved, and the hole wall is further effectively protected from being stable and not collapsing.
