[0002] "Civil engineering" refers to the planning, construction and maintenance of all infrastructure related to water, soil and culture. General civil engineering projects include: roads, water services, canals, flood control projects and transportation. In the past, all non-military civil engineering projects were classified into this category, but with the increasing breadth of engineering science, many contents that originally belonged to the scope of civil engineering have become independent disciplines. In a narrow sense, civil engineering is civil engineering, that is, construction engineering (or structural engineering), bridge and tunnel engineering, geotechnical engineering, highways and urban roads, railway engineering, etc. However, the current sand box has many shortcomings. For example, the amount of sand cannot be accurately controlled, the box wall is prone to wear and tear after long-term use, and it is easy to be damaged, and it is very inconvenient to disassemble. Therefore, we propose a sand reduction device for civil engineering. Utility Model Content

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-3The utility model provides an embodiment: a sand reduction device for civil engineering, comprising a bottom mounting plate 1, a supporting frame 2, a protective plate 5 and a box body 7. The four corners of the bottom of the box cover 6 are provided with snap-on buckles 601 fixed to the top of the box plate 3. When the device is used, the box cover 6 can be opened to put building materials into the box from the box opening. Box plates 3 are installed on both sides of the box body 7. Protective plates 5 are installed on the front and back sides of the box body 7. The protective plates 5 are embedded in the front and back sides of the box body 7. The protective plates 5 can isolate the sand from damaging the inner wall of the box body 7, avoiding the occurrence of sand wearing the inside of the box body 7 due to long-term loading of sand in the box body 7, and shortening the box body 7. The service life of the box body 7 is increased, and the durability of the box body 7 is increased. A pulling ring 501 is installed on one side of the protective plate 5. The protective plate 5 can be pulled out by pulling the pulling ring 501 to observe the change in the amount of sand. A pressing plate 4 is installed inside the box body 7. The pressing plate 4 is used in conjunction with building materials to press the sand down. Displacement members 401 are installed on both sides of the pressing plate 4. A slide groove 402 is installed on the top of the pressing plate 4. A displacement plate 403 is installed on the slide groove 402, and a fastening card cavity 404 is installed on the top of the displacement plate 403. Through the coordinated use of the slide groove 402, the displacement plate 403 and the fastening card cavity 404, the size of the building material can be adjusted according to the size of the building material. The distance can be adjusted to avoid the situation where the building material is too large or too small to be installed on the pressing plate 4. The sand box is used in conjunction with the sand box to increase the versatility of the equipment. A displacement track 301 is installed on the box plate 3. The displacement track 301 is connected to the displacement member 401. The displacement member 401 is installed at both ends of the pressing plate 4. After the building material is fixed on the top of the pressing plate 4, the displacement member 401 can drive the pressing plate 4 to move up and down through the displacement track 301 to press down the sand in the box body 7 so that the sand is tight and not loose. A bottom mounting plate 1 is installed at the bottom of the box body 7. Fastening rods 101 are installed at the four corners of the bottom mounting plate 1. The fastening rods 101 1 is provided with a limiting groove 102, which can be used in conjunction with a long pin. The long pin is inserted into the limiting groove 102 on the fastening rod 101 and then fixed to the ground, thereby improving the stability of the device. A bearing frame 2 is installed at the bottom of the bottom mounting plate 1, and a partition 202 is installed inside the bearing frame 2. A partition 202 is provided below the sand groove 201, and a sand groove 201 is provided at the bottom of the partition 202. The sand groove 201 can store the sand settled in the box body 7, and can also avoid the problem of excessive sedimentation of sand. Later, the amount of sand can be accurately controlled according to the change of the storage amount, thereby improving the accuracy of measurement.

[0020] Working principle: When using the device, first check whether the device is intact, whether the displacement track 301 and the displacement member 401 cannot be used normally, whether the fastening card cavity 404 is loose, and the building material cannot be fixed. Then place the device where it is needed, and use the limit groove 102 on the fastening rod 101 in conjunction with the long pin to fix the device to the ground, and then slide the displacement plate 403 on the slide groove 402 to adjust the position between the fastening card cavity 404, and then fix the required building material on the fastening card cavity 404, and then use the sand in the box 7 to fix the required building material. The displacement track 301 and the displacement member 401 can drive the building materials to slide up and down. When the building materials need to be removed, the partition 202 at the corresponding position is opened to allow the sand in the box 7 to flow into the sand trough 201, so that the amount of sand in the box 7 is reduced, thereby causing the pressing plate 4 to descend in the box 7. In the process of reducing the amount of sand, the position change of the amount of sand can be observed by the height of the protective plate 5, so as to facilitate the control of the degree of descent of the building materials. After use, the building materials on the pressing plate 4 are removed, the long pin is removed, the fastening rod 101 is retracted, and the partition 202 in the carrier 2 is pulled open by the pulling rod 203 to place the sand at the bottom, and then the entire device is taken out.

[0021] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
