[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] As attached Figure 1 As shown, a brick-built well structure involved in the utility model comprises a crushed stone foundation layer 1, a concrete foundation layer 2, a brick-built well body 3, and a steel mesh reinforcement layer 4 inside the well.

[0018] The crushed stone foundation layer 1 is arranged at the bottom; the concrete foundation layer 2 is arranged above the crushed stone foundation layer 1; the brick well body 3 is arranged above the concrete foundation layer 2; the well steel mesh reinforcement layer 4 is arranged inside the brick well body 3, including a steel mesh and a waterproof mortar layer.

[0019] The concrete foundation layer 2 is provided with reinforcement, and the foundation steel bars are arranged in a single-layer bidirectional A12 with a spacing of 200 mm.

[0020] As attached Figure 1 , 5 As shown, the brick-built well body 3 is composed of a plurality of concrete bricks 31. In one embodiment of the present application, the concrete bricks are MU10 bricks, which are laid in full strips and in full pieces. After one layer is laid, mortar is poured again to fill the gaps with mortar, and then the next layer of concrete blocks is laid. The vertical joints between the upper and lower layers of bricks should be staggered to protect the bottom.

[0021] The concrete brick 31 is a hollow brick formed by a mold, including an inner layer 311, an outer layer 312, and an intermediate support part 313. The two intermediate support parts 313 connect the inner layer 311 and the outer layer 312. A notch q1 is provided on the upper or lower part of the intermediate support part 313 to reduce the occurrence of hollowness when pouring concrete.

[0022] The steel mesh reinforcement layer 4 in the well covers the inside of the brick well body 3, and the waterproof mortar layer covers the steel mesh. In one embodiment of the present application, after the overall construction of the brick well is completed, the inside of the brick well is covered with a steel mesh. Then, the inside and outside of the well are powdered with 1:2 waterproof mortar to a thickness of 20 mm on the top of the well, and 1:2 waterproof cement slurry is used for plastering, grouting, seat mortar, and triangular mortar.

[0023] As attached Figure 2 , 3 4, in order to further improve the accuracy of the shape of the brick well body 3, so as to improve the integrity of the well body and the deformation resistance of the well body, the present application also provides a masonry auxiliary tool including a central support T1, a rotating cross bar T2, and an inner template T3, wherein the bottom of the central support T1 is provided with a supporting foot,

The inner diameters of the rotating vertical tube T21 and the lower limit ring T22 are the same as the outer diameter of the central bracket T1, and are sleeved on the outside of the central bracket T1. The lower limit ring T22 is fixed in the position of the central bracket T1 by tightening the limit nut, and the rotating vertical tube T21 is placed above the lower limit ring T22.

[0025] One end of the oblique support rod T23 is welded to the upper and lower ends of the rotating vertical pipe T21 to form a triangular structure. In the present application, a right-angled triangle structure is formed. The right-angled part is placed at the bottom during bottom construction, and the right-angled part can be placed at the top during upper construction.

[0026] The inner template T3 is arranged at the end of the oblique support rod T23 and is an arc-shaped plate or plate.
