Problems solved by technology

The only disadvantage is that the construction joints will be increased when the prefabricated components are assembled. If the construction joints are not properly handled, the service life of the prefabricated components will be reduced, the cost will be increased, and the safety hazard will be greatly increased during the use period. There are certain factors of social instability.

Embodiment 1

[0022] Such as figure 1 , figure 2 , image 3 As shown, in this embodiment, a prefabricated component is connected to a pipe concrete one-way injection device, including a feed pipe 1, a number of movable blades 2 that are rotatably arranged at one end of the feed pipe 1 and can be closed, and the feed pipe 1 and the movable vane 2 are connected with a reset structure 3 for making the movable vane 2 retracted.

[0023] During grouting, the feed pipe 1 is installed on the grouting port, the movable vane 2 is stretched into the grouting hole, the pipe used for grouting is connected to the feed pipe 1, and then the grouting starts. Under the action of the pressure of the slurry, the movable blades 2 are opened so that the slurry can flow smoothly. After the grouting is stopped, under the action of the reset structure 3, the movable blade 2 returns inward, thereby closing the feed pipe 1, which can prevent the backflow or leakage of the grout, and maintain the grouting pressur...

Embodiment 2

[0026] On the basis of the above embodiments, in this embodiment, the adjacent movable blades 2 can be sealed and connected, so as to increase the sealing strength between the movable blades 2 and the movable blades 2 after the movable blades 2 are closed, so as to prevent the slurry from leaking.

[0027] In this embodiment, the reset structure 3 uses a leaf spring. Utilize the pressure of grout to overcome the elastic force of spring leaf, make movable vane 2 open, after stopping grouting, spring leaf can drive movable vane 2 to draw in when itself recovers.

[0028] In this embodiment, the movable blade 2 is a part of a conical shape, and several movable blades 2 can be combined to form a complete conical shape. This avoids interfering with each other and leaving gaps when the movable blades 2 are drawn together. The conical structure formed after the movable vanes 2 are folded can maintain its sealing performance, and the conical surface bears the pressure of the slurry, ...

Embodiment 3

[0031] On the basis of the above embodiments, in this embodiment, a leak-proof cloth 4 is connected between the movable vanes 2 and the movable vanes 2 . After the movable blade 2 is opened, the leak-proof cloth 4 can be used to fill the gap between the movable blade 2 and the movable blade 2, and form a channel for the circulation of the slurry, so as to prevent the slurry from remaining on the movable blade 2 and cause the movable blade 2 to fail to completely gather.

[0032] In this embodiment, a leak-proof cloth 4 is connected between the movable vane 2 and the feed pipe 1 . After the movable blade 2 is opened, the gap between the leakproof cloth 4 movable blade 2 and the feed pipe 1 can be used to prevent the slurry from leaking through the gap between the movable blade 2 and the feed pipe 1, or remaining in the gap between the movable blade 2 and the feed pipe 1. The gap between the feed pipes 1 causes the movable blades 2 to fail to draw in completely.

Abstract

The invention discloses a concrete one-way injection device and injection method for a prefabricated part connecting pipeline. The concrete one-way injection device comprises a feeding pipeline and a plurality of movable blades, wherein the plurality of movable blades are rotatably arranged on one end of the feeding pipeline and can be folded, and reset structures which enable the movable blades to be folded are connected between the feeding pipeline and the movable blades. The concrete one-way injection device has the beneficial effects that the opening and closing of the movable blades can be controlled through the reset structures, so that the movable blades are opened during grouting and are closed after grouting is stopped, one-way circulation of grout is achieved, and the condition that the grout in a grouting hole is not full because the grout which enters a grouting channel flows back from a grouting opening is prevented.

Description

technical field [0001] The invention relates to the technical field of prefabricated component construction, in particular to a one-way concrete injection device and method for connecting pipelines of prefabricated components. Background technique [0002] The construction of prefabricated components is different from the construction of other projects on the ground. It is prefabricated by the prefabricated factory in advance and transported to the construction site after reaching the age. Its construction period, construction effect and construction safety are far superior to cast-in-place construction. Compared with cast-in-place construction, the cost is lower than that of cast-in-place construction, and it is superior to traditional cast-in-place construction in terms of on-site construction accuracy and forming effect. The only disadvantage is that construction joints will be added during the assembly of prefabricated components. If the construction joints are not prope...
