Referring to fig. 1 to 4, the present utility model provides a wall casting apparatus 10, where the wall casting apparatus 10 includes an outer mold plate 110, an inner mold plate 120, a prefabricated plugging member 130 and a sealing member 140, and the outer mold plate 110 and the inner mold plate 120 are spaced apart and connected to each other. Between the outer and

inner templates

110, 120 is a mold cavity 150. The preformed plugs 130 are disposed at the bottom of the mold cavity 150. The prefabricated closure 130 is intended to be in abutment with the ground or floor. Both sides of the prefabricated plugging member 130 are respectively abutted against the outer die plate 110 and the inner die plate 120. The prefabricated plugging piece 130 is provided with a buffer groove 131 and a plurality of slurry leakage holes 132, the buffer groove 131 is communicated with the die cavity 150, the slurry leakage holes 132 are formed in the bottom of the buffer groove 131, and the slurry leakage holes 132 penetrate through the bottom of the buffer groove 131. The bottom of the outer mold plate 110 and the bottom of the inner mold plate 120 are respectively provided with a sealing member 140, and the outer mold plate 110 and the inner mold plate 120 are respectively used for abutting against the ground through the sealing member 140.

In the wall pouring device 10, the outer die plate 110 and the inner die plate 120 are connected by the split bolts 20, and the cavity 150 between the outer die plate 110 and the inner die plate 120 is the space for filling the subsequent slurry and the position where the slurry is solidified to form the wall. When the device is used, the prefabricated plugging piece 130 is preset on the ground at the position of the wall to be grouted, and the formwork supporting robot is assisted in installing and positioning the outer formwork 110 and the inner formwork 120 during formwork supporting. After the outer template 110 and the inner template 120 are supported, the prefabricated plugging piece 130 is located at the bottom of the die cavity 150, the prefabricated plugging piece 130 is made of reinforced concrete, contacts with the slurry, and can be integrated into the whole wall after the slurry is solidified, and the prefabricated plugging piece is integrated with the integrally formed cast-in-place wall and is different from the integrally formed cast-in-place wall. The prefabricated plugging member 130 accommodates the slurry just poured in through the buffer slot 131, and the slurry leaks to the ground outside the prefabricated plugging member 130 along the slurry leakage opening 132, because the ground is uneven, a gap is formed between the prefabricated plugging member 130 and the ground, the slurry leaked to the ground flows to the bottom of the outer template 110 and the bottom of the inner template 120 along the gap, and the slurry can be further plugged by arranging the sealing members 140 at the bottom of the outer template 110 and the bottom of the inner template 120 respectively, so that the slurry is prevented from flowing outside the template. Due to the solidification characteristics of the slurry, the buffer slot 131 and the slurry leakage opening 132 of the prefabricated plugging member 130 slow down the contact speed of the slurry with the outer die plate 110 and the inner die plate 120 after the slurry is poured into the die cavity 150, the slurry is gradually solidified in the process, the slurry is a first plugging, the sealing member 140 acts to form a second plugging, and thus the plugging speed is effectively improved under the synergistic effect of the prefabricated plugging member 130 and the sealing member 140, and the construction efficiency is also improved from the side.

The usage method and the working principle of the wall pouring device 10 are as follows:

s1: fixedly placing a prefabricated plugging piece at the position where the wall is built;

s2: moving the mold robot to a prefabricated plugging piece;

s3: the mold robot carries out mold supporting of the outer mold plate and the inner mold plate;

s4: grouting is started after the formwork is supported;

s5: the slurry after grouting enters the buffer tank, and as the slurry leakage opening is formed below the buffer tank and the ground of the building blank is uneven, the slurry leaks along the slurry leakage opening below the buffer tank, and the leaked slurry fills the whole lower part of the buffer tank preferentially, so that the buffer tank is completely attached to the ground through slurry coverage;

s6: because the speed of the slurry leakage of the buffer tank is smaller than the grouting speed of the mould robot, and the lower part of the buffer tank is blocked by the sealing element of the template after being filled, the slurry liquid level of the buffer tank can continuously rise, and the slurry in the buffer tank is solidified and released heat along with the rising of the liquid level, so that the slurry below the prefabricated plugging element loses the flowing speed, and the self-sealing property of the cavity of the mould robot is formed.

The outer die plate 110 and the inner die plate 120 are collectively referred to as a die plate, and are made of a commercially available profile steel. The outer die plate 110 and the inner die plate 120 are in limit fixed connection with each other through split bolts. Of course, other fixing methods may be used for the connection between the outer and

inner templates

110 and 120, in addition to the relatively conventional split bolts, as long as the cavity 150 is formed by fixing the outer and

inner templates

110 and 120 at a distance.

The prefabricated plugging member 130 has a rectangular parallelepiped structure. The prefabricated plugging member 130 with the cuboid structure has flat two side surfaces, and can be better abutted with the outer template and the inner template. Gaps between the two side surfaces of the prefabricated plugging member 130 with the cuboid structure and the abutting surfaces of the outer die plate and the inner die plate are small, and slurry is difficult to leak out.

The prefabricated plugging member 130 is a cuboid structure made of reinforced concrete. The prefabricated plugging piece 130 of the cuboid structure made of reinforced concrete is contacted with the slurry and the slurry is solidified, and then the prefabricated plugging piece 130 can be integrated into the whole wall body, and the prefabricated plugging piece is integrated into one piece for in-situ wall building and is different from the in-situ wall building, so that the quality of the wall body is not influenced.

The prefabricated plugging piece 130 is prefabricated, and is manufactured in a factory or a construction site in advance according to the requirements of the size, the thickness, the materials and the like of the wall body, and is transported or moved to the position of the wall body to be built for fixed placement during construction. The prefabricated closure member 130 can be stably placed at a predetermined position by its own weight. The prefabricated closure 130 may assist the mold robot in positioning.

The buffer tank 131 is a U-shaped structure tank. Optionally, the buffer groove 131 is a V-shaped structural groove. The groove buffer groove 131 is provided to extend along the length direction of the prefabricated closure member 130. The buffer tank 131 serves to receive slurry for the first time of grouting so that the slurry previously poured is accumulated in the buffer tank 131.

A plurality of slurry leakage holes 132 are formed in the bottom of the buffer tank 131 at intervals. Optionally, a plurality of slurry leakage holes 132 are formed in the bottom of the buffer tank 131 at intervals of two rows. A plurality of slurry leakage openings 132 are provided in the bottom of the buffer tank 131 along the length direction of the prefabricated plugging member 130. The slurry leakage opening 132 penetrates through the bottom of the buffer tank 131, so that the buffer tank 131 is communicated with the bottom of the prefabricated plugging member 130, namely the ground of the building blank below the prefabricated plugging member 130. After the slurry poured in first is gathered in the buffer tank 131, it flows into the ground of the building blank under the prefabricated plugging member 130 under the action of the slurry leakage holes 132.

Because the ground is uneven, the slurry leaked to the ground will flow to the bottom of the outer template 110 and the bottom of the inner template 120 along the gap, and because of the solidification property of the slurry, the slurry solidifies and releases heat, the slurry below the prefabricated plugging member 130 loses the flowing speed, and the slurry solidified below the prefabricated plugging member 130 blocks the slurry leakage of the slurry leakage opening 132 in a reaction way, thereby forming the self-sealing property inside the cavity of the mold robot.

The sealing member 140 is a strip-shaped structure made of an elastic material. Optionally, the sealing member 140 is a strip-shaped structure made of a silicone material, which is also called a sealing rubber strip. The sealing member 140 is extended along the length direction of the outer die plate 110 or the inner die plate 120. The sealing adhesive tape can be pressed downwards by means of the gravity of the template, so that the sealing effect is achieved.

The sealing member 140 is connected with the outer die plate 110 or the inner die plate 120 in a detachable connection mode by bolts, so that the aged and damaged sealing member 140 can be conveniently replaced, and the construction efficiency is indirectly improved.

In order to improve the sealing effect, as shown in fig. 5 to 7, the bottom of the outer mold plate 110 is provided with a plurality of sealing members 140, and the plurality of sealing members 140 are spaced apart. Similarly, the bottom of the inner mold plate 120 is provided with a plurality of sealing members 140, and the plurality of sealing members 140 are spaced apart. In the present embodiment, the three seals 140 are provided at the bottom of the outer die plate 110 and the three seals 140 are provided at the bottom of the inner die plate 120. Therefore, the templates can be simultaneously pressed with the multi-layer sealing rubber strips, and even if the slurry overflows the sealing strip closest to the slurry under the condition of uneven ground, the second sealing strip can be blocked. In conclusion, the multi-layer plugging effect is achieved, and time is striven for the material losing fluidity and forming self-sealing.

The structure of the sealing member 140 is shown in fig. 8, and the top of the sealing member 140 has a flat structure 141 to facilitate the installation of the sealing member 140. The bottom of the seal 140 is a hemispherical structure 142. Optionally, the flat structure 141 and the hemispherical structure 142 are integrally formed. In this way, when the sealing element 140 is stressed, deformation is generated, and the bottom of the sealing element 140 with the hemispherical structure is in greater contact with the ground, so that the plugging efficiency can be improved. In this way, the slurry leakage speed is controlled through the sealing element 140 and the U-shaped groove, the multi-layer sealing device is used for sealing for multiple times, the slurry liquid level rises through the backlog of the U-shaped groove, the solidification releases heat, and the solidification above is accelerated. Finally, the slurry loses fluidity to form a self-sealing effect.

The utility model has the advantages that:

1. multilayer sealing effect: the first layer leaks to the second layer after the slurry leakage, and the second layer still has the sealing and blocking characteristics.

2. The prefabricated member assists in positioning and sealing, slurry leaks downwards through the notch of the prefabricated member, the slurry leakage speed is greatly reduced, and therefore time is striven for the slurry to lose fluidity, and the self-sealing effect is achieved in an auxiliary mode.

3. Compared with the full prefabricated member, the cast-in-situ sealing system has all advantages of the cast-in-situ wall body.

4. Compared with a pure cast-in-situ wall body, the cast-in-situ sealing system has more effective slurry leakage prevention effect.

5. The sealing of the material with the characteristic is carried out by fully utilizing the physical principle of the characteristic of the slurry material.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
