Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses prefabricated assembled well. Referring to fig. 1 and 2, the prefabricated assembly type well comprises arc-shaped precast blocks 1, and a plurality of precast blocks 1 are sequentially connected end to form a circular ring structure.

Referring to fig. 2 and 3, two grouting holes 11 have been seted up to the upper surface that is located prefabricated section 1 vertically, and grouting holes 11 run through prefabricated section 1 to after a plurality of prefabricated sections 1 splice from top to bottom, the reinforcing bar is stretched into towards the inside of grouting holes 11, then pours into the concrete into towards the inside of grouting holes 11, thereby fixes prefabricated section 1. The lower surface of precast block 1 sets up with the slope of the position of slip casting hole 11, and the incline direction sets up towards outwards inclining towards the central line that deviates from slip casting hole 11 along top-down direction of height gradually.

First recess 12 has been seted up to the upper surface that is located precast block 1, and the horizontal cross-section of first recess 12 is the arc structure, and the pitch arc of first recess 12 and the coaxial setting of pitch arc of precast block 1. The lower surface that is located precast block 1 is connected with first lug 2 for the fixed position of first recess 12, and the horizontal cross-section of first lug 2 is the arc structure, and the pitch arc of first lug 2 and the coaxial setting of pitch arc of precast block 1.

Referring to fig. 3 and 4, the depth of the first groove 12 is deeper than the height of the first protrusion 2, so that when the two precast blocks 1 are spliced up and down, the first protrusion 2 extends into the first groove 12, and a distance is left between the first protrusion 2 and the bottom of the first groove 12. The surface of the first groove 12 is inclined, and the inclination direction is gradually inclined downwards from the center of the first groove 12 towards the two plane side walls of the prefabricated block 1.

After the messenger is got into the concrete from slip casting hole 11, the concrete can flow into the inside that is located the first recess 12 of the prefabricated section 1 of next floor from slip casting hole 11 to fix first recess 12 and first lug 2 through the concrete, and when the precision of the size of prefabricated section 1 was lower when having great error, can balance through the gap between first recess 12 and the first lug 2, and pour fixedly through the concrete, thereby reduce the influence that the error that prefabricated section 1 produced when the preparation caused.

Referring to fig. 1 and 2, the horizontal plane on the upper surface of the prefabricated block 1 is provided with an arc-shaped steel bar groove 13, the arc line of the steel bar groove 13 and the arc line of the first groove 12 are coaxially arranged, so that when a plurality of prefabricated blocks 1 are sequentially connected end to end, the steel bar grooves 13 can be sequentially connected end to form an annular structure, and the annular steel bar 131 is placed towards the inside of the annular steel bar groove 13, so that the steel bar 131 is fixed in the inside of the steel bar groove 13, and the overall connection strength of the prefabricated block 1 is enhanced.

Referring to fig. 2 and 4, a plurality of protrusions 3 are fixedly arranged at the bottom of the first groove 12, and the height of each protrusion 3 is smaller than the height of a gap between the first groove 12 and the first bump 2 when the upper precast block 1 and the lower precast block 1 are spliced. Therefore, the connecting area of the upper precast block 1 and the lower precast block 1 after concrete is spliced and injected is increased through the protrusion 3, and the relatively fixed connecting strength between the two precast blocks 1 is enhanced.

Referring to fig. 2 and 3, the two opposite vertically arranged planar side walls of the precast block 1 are provided, wherein a second protruding block 4 is fixedly connected to one side of the two opposite vertically arranged planar side walls, and the second protruding block 4 is vertically arranged. And a second groove 14 is vertically formed in the position of the other side of the prefabricated section, which is opposite to the second bump 4, and when the two prefabricated sections 1 are spliced along the circumferential direction, the second bump 4 can extend into the second groove 14.

Referring to fig. 2 and 5, the length of the second projection 4 in the circumferential direction of the precast block 1 is smaller than the length of the second groove 14 in the circumferential direction of the precast block 1. When the two precast blocks 1 are spliced along the circumferential direction, the second projection 4 extends into the inner part of the second groove 14, so that a gap is formed between the second projection 4 and the second groove 14. When concrete is injected toward the inside of the grout hole 11, the concrete can flow into the inner gaps of the second protrusions 4 and the second grooves 14 along the inside of the first grooves 12, thereby filling the gaps.

And then reduce because the manufacturing accuracy scheduling problem of prefabricated section 1 for when splicing along circumference, second lug 4 stretches into the inside of second recess 14 and produces the great gap and shake or the relatively poor condition of concatenation effect.

Referring to fig. 2 and 3, a first baffle 41 is fixedly connected to a side wall of the second bump 4 away from the precast block 1, the first baffle 41 is arranged in an inclined manner, and an inclined direction of the first baffle 41 is gradually arranged in a downward inclined manner along a direction from one side close to the precast block 1 to one side away from the precast block 1. A second baffle 141 is fixedly connected to the bottom of the second groove 14, and the second baffle 141 is inclined in the same direction as the first baffle 41. And the projections of the first baffle plate 41 and the second baffle plate 141 along the vertical direction are smaller than the vertical direction projection of the gap generated after the second projection 4 extends into the second groove 14.

So that a gap is left between the first baffle plate 41 and the bottom of the second groove 14, and a distance is left between the second baffle plate 141 and the side wall of the second bump 4 away from the precast block 1, so that the concrete can flow along the vertical direction of the second groove 14.

So that when the concrete flows into the inner gaps of the second protrusions 4 and the second grooves 14, the contact area of the precast block 1 with the concrete can be increased by the first baffle plate 41, thereby enhancing the connection strength between the two precast blocks 1.

The implementation principle of prefabricated assembled well of this application embodiment does: by splicing the two prefabricated blocks 1 along the height direction, the first bump 2 extends into the first groove 12, and a distance is reserved between the upper surface of the first bump 2 and the bottom of the first groove 12. And then pour into the concrete through the inside towards slip casting hole 11 for the concrete enters into the inside in the gap that first lug 2 and first recess 12 produced, makes and produces the inaccurate problem of lining up when the concatenation of two prefabricated section 1 that prefabricated section 1 caused because the precision error that pours the production in-process of production, can compensate through the gap that first lug 2 and first recess 12 produced, and then fixes through the concrete.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
