Description

Technical Field

[0001] This application relates to the field of diaphragm wall construction technology, and in particular to a diaphragm wall trenching device and system. Background Technology

[0002] In the fields of building construction and foundation engineering, trench milling machines are widely used as important trenching equipment in projects such as diaphragm walls and deep foundation pit support. The trench milling machine cuts through the ground using a rotating grab bucket to form a trench that meets design requirements.

[0003] A grooving machine moves along a fixed path using guide rails or guide wheels, while relying on limiting devices or sensors to detect and adjust its horizontal position, thus ensuring stability and accuracy during processing. However, in actual operation, the movement path of the grooving machine may be affected by factors such as uneven ground, guide rail installation errors, or irregular surfaces of the processed material, causing the machine to deviate horizontally. This deviation directly affects the perpendicularity of the hole, thereby impacting the processing quality. Utility Model Content

[0036] like Figure 1 As shown, an embodiment of this application provides a diaphragm wall trenching device, mainly used for trenching during diaphragm wall construction. The diaphragm wall trenching device includes a trench 110 and an auxiliary trenching mechanism 120.

[0037] Among them, guide walls 111 are respectively provided on the two walls of the trench 110 along the width direction.

[0038] The guide wall 111 is formed by casting along the design axis of the underground continuous wall. It is usually a reinforced concrete structure and is used to guide the trenching machine and position the trench section.

[0039] In actual operation, the movement path of the milling machine may be affected by factors such as uneven ground, guide rail installation errors, or irregular surface of the processed material, causing the milling machine to deviate in the horizontal direction.

[0040] To address the aforementioned issues, an auxiliary grooving mechanism 120 is mounted on two guide walls 111 and located at the opening of the trench 110. The auxiliary grooving mechanism 120 includes a first limiting member 121 and a second limiting member 122 spaced apart along the trench width direction D2, and a first grid 123 and a second grid 124 spaced apart along the trench length direction D1. The first limiting member 121, the first grid 123, the second limiting member 122, and the second grid 124 enclose a processing groove 125. In the communicating direction of the trench 110, the projection of the processing groove 125 falls within the two guide walls 111. During processing, the milling machine's grab and robotic arm pass through the processing groove 125, thereby guiding the movement path of the grab and robotic arm, reducing horizontal deviation of the milling machine, and improving the verticality of the groove.

[0041] In some embodiments, the processing groove 125 has a first opening 1251 facing away from the groove 110 and a second opening 1252 close to the groove 110. The cross-sectional area of ​​the first opening 1251 is larger than that of the second opening 1252, which facilitates the insertion of the robotic arm and grab of the milling machine into the processing groove 125. During the process from the first opening 1251 to the second opening 1252, as the cross-sectional area decreases, the movement path of the robotic arm and grab is gradually guided.

[0042] In some embodiments, such as Figure 1 As shown, in the direction away from the groove 110, the cross-sectional area of ​​the first opening 1251 gradually increases, and the first opening 1251 is trumpet-shaped, which facilitates the insertion of the milling machine's robotic arm and grab into the processing groove 125.

[0043] In some embodiments, the size of the second opening 1252 in the trench width direction D2 is smaller than the size of the second opening 1252 in the trench length direction D1. By increasing the size of the second opening 1252 in the trench length direction D1, interference between the grab and the first grid 123 or the second grid 124 in the opening and closing trench 110 is avoided. At the same time, by reducing the size of the first opening 1251 in the trench width direction D2, the offset of the grab in the trench width direction D2 is reduced, and the verticality of the trench is improved.

[0044] In some embodiments, the trench 110 has a plurality of processed sections 112 along its length.

[0045] like Figure 2 As shown, trench 110 has three processing sections 112 along its length. According to the construction sequence, they are divided into "Level 1 trench (left side)," "Level 2 trench (right side)," and "Level 3 trench (center)." In the three-grab trenching process, the first and second grabs are both side grabs, where the grab bucket first excavates from the side of the trench section, forming a side trench section. The third grab is a center grab, where the grab bucket excavates in the middle of the trench section, forming the complete trench width. This "digging from both sides first, then digging from the middle" method ensures balanced force on both sides of the grab bucket. By the third grab, both sides of the grab bucket have been excavated, allowing for balanced force distribution in the middle of the soil, effectively correcting deviations and improving trench verticality.

[0046] In some embodiments, the size of the second opening 1252 in the trench length direction D1 does not exceed the size of any processing segment 112 in the trench length direction D1.

[0047] In one embodiment, the dimension of the second opening 1252 in the trench length direction D1 is equal to the dimension of any processed segment 112 in the trench length direction D1. For example, in the first-stage trench, the dimension of the second opening 1252 in the length direction is equal to the dimension of the first-stage trench in the trench length direction D1. In this way, during the processing of the first-stage trench, there is no need to move the auxiliary trenching device, thus improving construction efficiency.

[0048] In some embodiments, such as Figure 1 As shown, the first limiting member 121 includes a first limiting plate 1211 and a plurality of first reinforcing plates 1212, and the second limiting member 122 includes a second limiting plate and a plurality of second reinforcing plates. The plurality of first reinforcing plates 1212 are disposed on the side of the first limiting plate 1211 away from the second limiting plate, and the plurality of second reinforcing plates are disposed on the side of the second limiting plate away from the first limiting plate 1211. By setting the first reinforcing plates 1212 and the second reinforcing plates, the deformation of the first limiting member 121 and the second limiting member 122 is reduced, and the grooving accuracy is improved.

[0049] In some embodiments, such as Figure 1 As shown, the first grille 123 has a first alignment groove 1231 and a second alignment groove 1232 spaced apart on the side near the groove 110. The first alignment groove 1231 is located on the side of the first limiting plate 1211 away from the second limiting plate, and the second alignment groove 1232 is located on the side of the second limiting plate away from the first limiting plate 1211. Both the first alignment groove 1231 and the second alignment groove 1232 are through grooves that connect along the length direction D1 of the groove.

[0050] The second grille 124 has a third alignment groove 1241 and a fourth alignment groove 1242 spaced apart on the side near the groove 110. The third alignment groove 1241 is located on the side of the first limiting plate 1211 away from the second limiting plate, and the fourth alignment groove 1242 is located on the side of the second limiting plate away from the first limiting plate 1211.

[0051] It should be noted that the first grille 123 and the second grille 124 are mirror images of each other. The first alignment groove 1231 and the third alignment groove 1241 are connected along the length of the groove 110; the second alignment groove 1232 and the fourth alignment groove 1242 are connected along the length of the groove 110.

[0052] In some embodiments, in conjunction with reference to Figure 2 and Figure 3 A clearance groove 113 is provided on the side of the guide wall 111 away from the processing groove 125. The clearance groove 113 extends along the length of the groove 110 so that the end of the guide wall 111 protrudes.

[0053] When the auxiliary grooving mechanism 120 is mounted on the guide wall 111, one end of the guide wall 111 is engaged with the first alignment groove 1231 and the third alignment groove 1241, and the other end of the guide wall 111 is engaged with the second alignment groove 1232 and the fourth alignment groove 1242. This engagement structure improves the stability of the auxiliary grooving mechanism 120.

[0054] In some embodiments, such as Figure 3 The auxiliary troughing mechanism 120 also includes a first rib 1233 and a second rib 1234. The first rib 1233 is located on the side of the second grille 124 closest to the first grille 123, connecting the second grille 124 and the first limiting plate 1211. The second rib 1234 is located on the side of the second grille 124 closest to the first grille 123, connecting the second grille 124 and the second limiting plate. By providing the first rib 1233 and the second rib 1234, the overall stability of the auxiliary troughing mechanism 120 is improved.

[0055] In some embodiments, the first grille 123 and the second grille 124 are provided with multiple lifting holes 1235 on the side away from the trench 110 to facilitate the lifting and moving of the auxiliary trenching mechanism 120.

[0056] The construction process of the auxiliary trenching mechanism 120 is as follows:

[0057] The first limiting plate 1211 and the second limiting plate are spaced apart, and the dimensions of the first limiting plate 1211 and the second limiting plate at the second opening 1252 are equal to the dimensions of the milling machine, so that the grab bucket and the mechanical arm of the milling machine can pass through the processing groove 125, and the purpose of guiding the movement path of the milling machine can be achieved.

[0058] Then connect the first grille 123 and the second grille 124 to the ends of the first limiting plate 1211 and the second limiting plate.

[0059] Then, the first reinforcing plate 1212 is assembled into the first limiting plate 1211, and the second reinforcing plate is assembled into the second limiting plate.

[0060] The auxiliary grooving mechanism 120 is hoisted as a whole onto the guide wall 111 through the hoisting hole 1235, so that the end of one guide wall 111 is locked in the first alignment groove 1231 and the third alignment groove 1241, and the end of the other guide wall 111 is locked in the second alignment groove 1232 and the fourth alignment groove 1242.

[0061] Adjust the position of the auxiliary grooving mechanism 120 along the length of the groove 110 so that the processing groove 125 is aligned with the edge of the primary groove, and then fully lower the auxiliary grooving mechanism 120.

[0062] After the primary groove is processed, the auxiliary groove forming mechanism 120 is moved to the secondary groove by a hoist or other equipment, to the edge of the processing groove 125 and the secondary groove, and then the auxiliary groove forming mechanism 120 is completely lowered. In this way, the processing of the tertiary groove is completed.

[0063] It should be noted that the dimensions of the primary, secondary, and tertiary trenches are the same along the trench length direction D1, which avoids the need for multiple assembly of the alignment auxiliary mechanism and improves construction efficiency.

[0064] This application provides a diaphragm wall trenching system, including the diaphragm wall trenching device and a trenching machine as described in any of the above embodiments. The trenching machine includes a robotic arm and a grab bucket. The robotic arm drives the grab bucket to move. In the width direction of the trench 110, the size of the grab bucket or robotic arm is the same as the size of the trench 125. When the size of the grab bucket is larger than the size of the robotic arm, the size of the trench 125 is equal to the size of the grab bucket. When the size of the grab bucket is smaller than the size of the robotic arm, the size of the trench 125 is equal to the size of the robotic arm.

[0065] During the processing, the grab and robotic arm of the milling machine pass through the processing groove 125, thereby guiding the movement path of the grab and robotic arm, reducing the deviation of the milling machine in the horizontal direction, and improving the verticality of the groove.
