Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a self-locking one-way valve component for grouting. Background Art
[0002] As building structure design and construction technologies become more and more novel, complex and diversified, especially the promotion and application of prefabricated structure and prestressed structure technology, structural grouting construction methods are becoming more and more novel and complex, and quality requirements are becoming higher and higher.
[0003] Traditional grouting methods, especially side grouting and top grouting, have high requirements on material technology and workers' actual operation level. On the one hand, the grouting material needs to have greater fluidity to ensure the density and fullness of the grouting construction. On the other hand, the grouting backflow during the grouting process must be minimized (especially side grouting and top grouting construction) and grouting must be done from the top of the structure after the bottom grouting construction. This not only greatly increases the loss of labor and materials, but also places very high requirements on the actual operation of workers. In addition, grouting bubbles are easily formed during grouting, which is extremely unfavorable to the quality control of grouting construction.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a self-locking one-way valve assembly for grouting is proposed, in order to achieve a more practical purpose. Utility Model Content

[0010] Furthermore, the material of the valve-type one-way valve head is not limited to plastic, metal or others.
[0011] Furthermore, the valve-type one-way valve head can be replaced by the spring-type one-way valve head.
[0012] Furthermore, the shrapnel-type one-way valve head includes a support portion, a fan blade shrapnel and a grouting port, the fan blade shrapnel is arranged at both ends of the outer side of the support portion, and a grouting port is opened in the inner center of the support portion.

The placement position of the one-way valve assembly in the grouting pipe can be selected according to needs, and it has wider adaptability.

[0029] The grouting pipe 1 and the valve-type one-way valve head 3 can be integrally formed; the valve-type one-way valve head 3 is in the shape of a bottle cap, with "ribs" added under the valve, and the number of "ribs" can be adjusted according to actual grouting needs; the valve-type one-way valve head 3 can be pasted on the inner side of the grouting channel 2 as a separate valve component; the material of the valve-type one-way valve head 3 is not limited to plastic, metal or other; the valve-type one-way valve head 3 can be replaced by a spring-type one-way valve head 5;
[0030] The grouting pipe 1 and the valve-type one-way valve head 3 are arranged on the inner wall. A simple one-way guide valve is added inside the grouting port. During construction, the slurry is injected from the outside of the component through the one-way valve.
