[0040] In order to make the purpose, technical scheme and advantages of the application more clear, the application is further described in detail below in combination with examples and drawings. The illustrative embodiments of the application and their descriptions are only used to explain the application and do not limit the application.

[0041] In the first aspect, in combination with Figures 1-4 The embodiment of the application provides an anchor type retaining formwork, which comprises a column 1, a filling body 2, a baffle 3 and an anchor rod 4.

[0042] The number of columns 1 is multiple, and the multiple columns 1 are arranged side by side, that is, the length direction of the multiple columns 1 is parallel to each other and is arranged in a linear direction. In the usual direction, the column 1 is usually connected vertically to the ground. The column 1 as a whole can be designed as a rectangular rod body shape. The column 1 can be cast from reinforced concrete, so as to facilitate the combination with subsequent construction materials. The column 1 can also be configured as a steel column, which can be used as a structural reinforcement after being combined with subsequent construction materials, and at the same time provides a more superior support effect by using the characteristics of high structural strength. The column 1 is provided with a filling slot 12 penetrating along the length direction of the column 1, that is, the length of the filling slot 12 is equal to the length of the column 1. The cross-sectional shape of the filling slot 12 can be, for example, rectangular, trapezoidal, elliptical, circular and the like. The cross-sectional shape of the filling slot 12 is usually designed as rectangular to facilitate the construction of the filling body 2. A plurality of let - go through holes 13 are arranged in the length direction of the column 1 on the bottom of the filling slot 12.

[0043] The filling body 2 is located in the filling slot 12. The filling body 2 comprises brick sections 21 and mortar sections 22 arranged alternately along the length direction of the column 1, that is, each two brick sections 21 are connected by a mortar section 22, and the both ends of the filling body 2 are brick sections 21. The mortar section 22 corresponds in position to the let - go through hole 13, that is, in the depth direction of the filling slot 12, each mortar section 22 covers each let - go through hole 13, and the number of mortar sections 22 is equal to the number of let - go through holes 13.

[0044] The baffle 3 is located between two adjacent columns 1 and is clamped with the column 1. The baffle 3 can be formed by pouring reinforced concrete, and the reinforcement can give the baffle 3 a certain flexibility, so that when the soil 5 is disturbed, the baffle 3 can provide a certain buffer through its own micro-deformation to prevent the baffle 3 from suddenly breaking.

[0045] The anchor rod 4 passes through the let-in hole 13 at one end and is located in the mortar section 22, that is, the end of the anchor rod 4 is embedded in the mortar section 22 to form a stable connection with the mortar section 22, and the bricklaying section 21 is connected through the mortar section 22 to form an integral whole with the anchor rod 4, and the other end is used to be embedded in the soil 5. The anchor rod 4 is generally in the shape of a round rod, and the diameter of the anchor rod 4 is smaller than the diameter of the let-in hole 13. When the soil 5 is disturbed, the gap between the anchor rod 4 and the let-in hole 13 serves as a deformation space for the anchor rod 4, and the anchor rod 4 provides a certain buffer through its own micro-deformation to avoid a large lateral load on the column 1.

[0046] When the anchor-tension type soil retaining mold plays a soil retaining role, the pressure of the soil 5 is borne by the baffle 3 and the column 1 together and is finally transmitted to the ground through the column 1. When construction or heavy machinery operation or other heavy loads in the adjacent position cause vibration, the soil 5 is disturbed, that is, there is a lateral load parallel to the direction of the baffle 3 surface. At this time, the pressure generated by the soil 5 is transmitted to the mortar section 22 by the anchor rod 4, each mortar section 22 uniformly transmits the load to the whole filling body 2, and then the filling body 2 transmits the load to the column 1 and the baffle 3, and finally the load is transmitted to the ground through the column 1. In addition, when the soil 5 is disturbed, there is also a lateral load perpendicular to the direction of the baffle 3 surface. These loads are mainly borne by the column 1 and the baffle 3 together. Among them, the baffle 3 utilizes its flexible property to produce a certain micro-deformation to provide a buffer. At this time, the baffle 3 on both sides of the column 1 will generate a certain extrusion force on the column 1 in the middle, which is resisted by the bricklaying body in the filling body 2 to prevent the column 1 from deforming and cracking, and at the same time, to prevent the mortar section 22 from being extruded and broken, so as to ensure that the soil retaining mold continuously and effectively plays the anti-vibration effect.

[0047] The anchor-tension type soil retaining mold provided by the embodiment of the present application can be prefabricated in a factory, and combined with the on-site construction of the filling body 2 to form a modular and on-site masonry cooperative construction mode. Compared with the existing full-masonry construction process, the construction efficiency is effectively improved, the labor consumption is reduced, the masonry material consumption is reduced, and good economic effects are achieved.

[0048] The anchor-pulling type soil retaining mold provided in the embodiment of the application has a certain gap between the anchor rod 4 and the yielding perforation 13, which can be used as a moving space of the anchor rod 4. When the soil body 5 is disturbed, the anchor rod 4 has a certain flexibility, and a certain buffering capacity is provided to avoid that the vertical column 1 bears a large lateral load. Meanwhile, the load is directly transmitted to the mortar section 22, the mortar section 22 transmits the load to the vertical column 1 as an intermediate force transmission structure, and the vertical column 1 does not bear the load directly, which is beneficial to ensure the structural integrity of the vertical column 1.

[0049] The anchor-pulling type soil retaining mold provided in the embodiment of the application has a certain gap between the anchor rod 4 and the yielding perforation 13, which can be used as a moving space of the anchor rod 4. When the soil body 5 is disturbed, the anchor rod 4 has a certain flexibility, and a certain buffering capacity is provided to avoid that the vertical column 1 bears a large lateral load. Meanwhile, the load is directly transmitted to the mortar section 22, the mortar section 22 transmits the load to the vertical column 1 as an intermediate force transmission structure, and the vertical column 1 does not bear the load directly, which is beneficial to ensure the structural integrity of the vertical column 1.

[0050] In the embodiment of the application, the ground is the ground of a construction site, rather than a ground surface. For example, the soil retaining mold is usually constructed in a pit, and the pit bottom surface is the ground.

[0051] In the embodiment of the application, the yielding perforation 13 mainly provides a space for the anchor rod 4, and therefore the cross-sectional shape of the yielding perforation 13 can be any shape, as long as a gap can be formed between the anchor rod 4 and the hole wall of the yielding perforation 13 when the anchor rod 4 passes through the yielding perforation 13. Usually, the yielding perforation 13 is constructed as a circular perforation to reduce the construction difficulty. For example, when the vertical column 1 is designed as a reinforced concrete, the yielding perforation 13 is designed as a circular hole to facilitate demolding. In addition, the anchor rod 4 is usually a round rod component, and the yielding perforation 13 is designed as a circular hole to facilitate providing a uniform moving gap for the anchor rod 4 in the circumferential direction.

[0052] In some optional embodiments, reference can be made to Figure 2, the length direction of the anchor rod 4 and the length direction of the column 1 form an angle, that is, the anchor rod 4 is inclined relative to the plate surface of the baffle 3, which can prevent the anchor rod 4 from transmitting axial load to a certain extent, avoid the mortar section 22 being positively supported, and help to ensure the structural integrity of the filling body 2; in addition, when the soil body 5 applies a transverse load perpendicular to the plate surface of the baffle 3, the direction of the transverse load and the axis of the anchor rod 4 form an angle, and since the diameter of the anchor rod 4 is smaller than the diameter of the let-in hole 13, the anchor rod 4 can deform slightly based on its flexible characteristics to adapt to the disturbance of the soil body 5, and will not be directly driven to translate by the soil body 5 to cause relative sliding between the anchor rod 4 and the mortar section 22, which helps to ensure the stability of the connection between the mortar section 22 and the anchor rod 4.

[0053] In some optional embodiments, the extension direction of the let-in hole 13 forms an angle with the length direction of the column 1 so that the anchor rod 4 is located in the central position of the let-in hole 13, that is, the extension direction of the let-in hole 13 also forms an angle with the plate surface of the baffle 3, which can ensure that the anchor rod 4 has uniform clearance in the circumferential direction, and at the same time ensure that the let-in hole 13 has a smaller opening area, which helps to ensure the structural integrity of the column 1, thereby ensuring that the column 1 still has good structural strength after being opened.

[0054] In some optional embodiments, the hole edge of the let-in hole 13 is configured as a rounded corner structure, and when the anchor rod 4 deforms too much to contact the hole edge of the let-in hole 13, the smooth surface can adapt to the curved shape of the anchor rod 4, avoid stress concentration caused by the contact between the anchor rod 4 and the sharp edge, and prevent the anchor rod 4 from breaking.

[0055] In some optional embodiments, the gap between the anchor rod 4 and the let-in hole 13 is filled with a buffer body.

[0056] In the embodiments of the present application, since the formwork needs to be buried in the soil later, the buffer body can be an anti-corrosion rubber block; the anti-corrosion rubber block can be connected with the hole wall of the let-in hole 13 in a bonding manner to prevent the anti-corrosion rubber block from gradually separating from the let-in hole 13 under the action of the anchor rod 4, and the anti-corrosion rubber block also forms a bond with the anchor rod 4, so that the anchor rod 4 can be subjected to double elastic force when it deviates, thereby providing effective buffering for the anchor rod 4 to prevent excessive elastic deformation of the anchor rod 4; at the same time, the anti-corrosion rubber block can also protect the column 1 to avoid rigid contact between the anchor rod 4 and the column 1, and ensure the structural integrity of the column 1.

[0057] In some optional embodiments, the let-in hole 13 can be used in combination with Figure 4 and Figure 5 , the baffle 3 extends outward on both sides to form a protruding edge, and the column 1 is provided with a clamping groove 11, and the protruding edge is embedded in the clamping groove 11 to form a clamping fit.

[0058] In the embodiments of the present application, the card slot 11 can be designed as a through slot, that is, the length of the card slot 11 is equal to the length of the column 1; the shape of the card slot 11 can be designed as a rectangle, and the cross section of the convex edge on the baffle 3 is also designed as a rectangle suitable for the card slot 11. In this way, during the construction stage, all the columns 1 can be positioned first, and then the baffle 3 is inserted and connected between the two columns 1 through hoisting, which can help to ensure the accurate positioning of the column 1, ensure the accurate positioning of the soil retaining formwork as a whole, and ensure that the contact conditions of the soil retaining formwork with the soil 5 are consistent in all directions, thereby ensuring that the soil retaining formwork is uniformly stressed.

[0059] In some optional embodiments, as shown in Figure 3 The width of the card slot 11 is greater than the thickness of the convex edge, that is, there is a gap between the convex edge and the slot wall of the card slot 11. This design can facilitate the clamping operation of the baffle 3 and the column 1, and at the same time, the gap also serves as a micro-motion space for the convex edge on the baffle 3, which can prevent the convex edge from being rigidly pressed with the card slot 11 when the baffle 3 is slightly deformed, and is beneficial to ensure the structural integrity of the column 1 and the baffle 3. In actual implementation, the convex edge extends from one of the plate surfaces of the baffle 3, that is, one side of the baffle 3 is a complete plane, and the other side is a stepped surface. Therefore, the gap can be filled with a certain amount of soil 5. Under the long-term disturbance of the soil 5, the soil 5 in the gap will be pressed more tightly, thereby making the baffle 3 more stable relative to the column 1. When the formwork is finally buried in the soil 5, the baffle 3 and the column 1 do not have relative displacement.

[0060] In some optional embodiments, the baffle 3 and the column 1 are gap-fitted, that is, there is a gap between the convex edge on the baffle 3 and the card slot 11 in the transverse direction parallel to the plate surface of the baffle 3, and a buffer layer is arranged between the baffle 3 and the column 1.

[0061] In the embodiments of the present application, the gap between the baffle 3 and the column 1 allows the baffle 3 to have a slight transverse displacement, which is mainly to adapt to the elastic deformation of the anchor rod 4. That is, the transverse displacement of the soil 5 under the action of the anchor rod 4 can be reduced, and the baffle 3 produces a slight displacement under the friction force between the baffle 3 and the soil 5, and then contacts the column 1. When the soil 5 is disturbed slightly, the baffle 3 has a small displacement, and the gap between the baffle 3 and the column 1 provides displacement space for the baffle 3. At this time, the disturbance of the soil 5 is basically resisted by the anchor rod 4, the transverse load applied by the soil 5 is consumed by the slight elastic deformation of the anchor rod 4, and the load is directly transmitted to the column 1 through the anchor rod 4. When the soil 5 is disturbed greatly, the baffle 3 has a large displacement, and the transverse load applied by the soil 5 is first borne by the anchor rod 4. When the baffle 3 contacts the column 1, there is a friction force between the soil 5 and the baffle 3. At this time, the transverse load of the soil 5 is transmitted to the column 1 by the anchor rod 4 and the baffle 3 together, which can prevent the anchor rod 4 from being deformed excessively, and is beneficial to ensure the structural integrity of the anchor rod 4, so that the anchor rod 4 can continue to play an effective role.

[0062] In some optional embodiments, the anchor rods 4 are provided with concrete adhesive to form an adhesive with the soil 5, which can make the soil 5 near the anchor rods 4 form an integral whole, and make the soil 5 near the anchor rods 4 form an integral whole with the anchor rods 4, indirectly increase the bearing area of the anchor rods 4, which can avoid stress concentration at the contact between the soil 5 and the anchor rods 4, and cause local damage of the soil 5.

[0063] In a second aspect, the embodiments of the present application provide an anchor and pull type retaining form construction method for forming any one of the anchor and pull type retaining forms as described in the first aspect, and the anchor and pull type retaining form construction method comprises the following contents:

[0064] S1, prefabricating the retaining plates 3 and the columns 1 in a factory.

[0065] The retaining plates 3 and the columns 1 can be formed by pouring reinforced concrete; if the retaining plates 3 and the columns 1 are formed by steel components, they can also be formed by machine tool processing or casting.

[0066] S2, excavating the soil 5 into a groove.

[0067] S3, drilling anchor holes into the soil 5 from the groove wall, wherein in the conventional construction orientation, the extension direction of the anchor holes forms an angle with the groove bottom surface, that is, the anchor holes are inclined holes.

[0068] S4, arranging the columns 1.

[0069] S5, grouting into the anchor holes and arranging the anchor rods 4 in the anchor holes.

[0070] In the embodiments of the present application, the grouting can be additionally performed by excavating grouting holes, or by the grouting through the accommodation perforations 13 on the columns 1. The construction sequence of arranging the columns 1 first and then grouting can ensure the pose and position of the anchor rods 4 during the fixing of the anchor rods 4, and ensure that the anchor rods 4 can be accurately matched with the columns 1 after being fixed in the anchor holes.

[0071] S6, after the grout in the anchor holes is solidified, the brick segments 21 are built in the filling grooves 12 of the columns 1.

[0072] S7, the space between the adjacent brick segments 21 is closed by a formwork, and grouting is performed to form the mortar segments 22.

[0073] In the embodiments of the present application, the masonry is performed first and then the grouting is performed, which can avoid the alternate construction of masonry and grouting, and can improve the construction efficiency. When the brick laying section 21 is constructed, the positioning plate can be arranged in the filling groove 12 to support the brick masonry; the grouting formwork can be the commonly used wooden formwork, and the sealing between the grouting formwork and the stand column 1 should be ensured during the pouring process to prevent the overflow of the mortar; during the grouting process, the adjacent brick laying sections 21 serve as the upper and lower formworks of the mortar section 22, and the filling groove 12 does not need to be additionally constructed with the pouring formwork, which is beneficial to simplify the construction process and improve the construction efficiency to a certain extent.

[0074] S8, after the mortar section 22 is coagulated, the baffle 3 is clamped between the adjacent stand columns 1.
