Description

Technical Field

[0001] The invention relates to the technical field of engineering grouting construction, and in particular to a device for regulating and controlling grouting pressure and deformation of a toe plate in a hilly broken zone. Background Art

[0002] During the construction phase in hilly areas, grouting of the broken zone toe plate is a key step in ensuring the stability of the dam foundation and its anti-seepage performance. However, due to the complex geological conditions in hilly areas, the fractured zone rock mass has developed cracks, a loose structure, and the existence of sudden stress changes and releases, traditional grouting technology faces significant challenges in pressure control.

[0003] Fracture zones in hilly areas are often accompanied by closed unfilled cracks, fault crossings, and shallow rock fractures. Traditional grouting technology lacks a detailed analysis of crack aperture, filling rate, and fracture zone travel path, resulting in a rough grouting pressure control strategy that is difficult to adapt to dynamic construction needs under complex geological conditions.

[0004] In the grouting of the toe plate in the broken zone, it is necessary to meet the requirements of anti-seepage and structural safety at the same time. Traditional processes often face a dilemma due to insufficient pressure control accuracy. If the pressure is increased in pursuit of anti-seepage effect, it may cause the toe plate to crack. If the pressure is reduced to protect the structure, it may cause the grouting to be loose. Summary of the Invention

[0049] When the scheme is used:

[0050] S1, the device base 101 is placed in a broken toe plate area, and is preliminarily fixed through the positioning rivet hole 105, at this time, the claw 111 at the bottom of the supporting adjusting base 1001 can adaptively embed the gap in the broken rock mass at the claw tip 127 under the gravity and slight pressure, the stress sensing sheet 128 on the stress monitor 112 can realize real-time sensing of the contact stress change transmitted by the claw, and the data is transmitted to the data transmission module 119 on the vertical supporting column 114 through the data connection line 122.

[0052] S3. During the grouting process, the grouting material enters the grouting storage 103 through the grouting pipe 117, the grouting connecting plate 106, and the grouting connecting pipe 120. When the stress value fed back by a certain monitoring point, such as a specific stress monitor 112, approaches or exceeds the preset safety threshold, indicating that the rock mass in the area is at risk of instability or excessive deformation, the control end can immediately issue an instruction or the preset logic of the device can be automatically triggered to drive the pressure regulating push rod 107 at the corresponding position to move. The push rod 107 acts on the push rod support seat 125, and applies or releases the supporting force to the rock mass below through the vertical support column 114 and the circular support plate 113, thereby playing a role of stabilizing support for the oblique connecting rod 115 and improving the stability of subsequent grouting work.

[0053] S4. When grouting pressure and deformation are coordinated and regulated, the active adjustment of local support force directly affects the ability of the rock mass in this area to withstand grouting pressure. Through the above adjustment, the device substantially changes the boundary conditions of the grouting operation surface, so that the optimal grouting pressure can be safely maintained or adjusted in stress-sensitive areas, avoiding further rock fragmentation or uncontrolled expansion and deformation of existing cracks due to excessive pressure, and avoiding loose grouting due to too low pressure. The oblique connecting rods 115 on both sides and the array of adjustment pillars 108 thereon ensure that the support force can be accurately applied along the key force direction.
