Description

Technical Field

[0001] The present application belongs to the technical field of anti-seepage wall construction, and in particular relates to a method and system for monitoring the wall construction speed before the construction of an anti-seepage wall. Background Art

[0002] The TRD method (Trench Cutting Re-mixing Deep Wall method) is a highly efficient, one-step underground continuous wall construction technology. Using a chainsaw-like cutter to horizontally cut the soil and simultaneously inject a curing agent, the TRD method completes soil cutting, mixing, and wall formation in a single step. Its core advantages lie in the consistent and uniform wall formation and high vertical precision. It is suitable for projects such as anti-seepage curtains and retaining walls in complex geological conditions (such as soft soils and sand layers). It is widely used in water conservancy projects, subway foundation pits, and contaminated soil isolation.

[0003] During the construction process, the forward speed needs to be dynamically synchronized with the pumping volume of the curing agent. If the speed is too fast, the mixing time of the curing agent and the soil will be insufficient, which may lead to uneven mixing, the appearance of "sandwich layers" that have not reacted fully, or weak areas with uneven distribution of curing agent, which will reduce the wall's impermeability and strength; if the speed is too slow, excessive grouting may occur, causing material waste or local expansion and cracking.

[0004] Therefore, the forward wall speed is the core variable for quality control of the TRD method. To ensure wall quality, the forward wall speed must be dynamically controlled in combination with geological conditions, equipment performance, and material properties to avoid uneven mixing, insufficient strength, or leakage risks of the anti-seepage wall caused by improper speed. However, conventional forward wall speed control methods rely on the operator's subjective experience and estimated cutting speed, and lack real-time monitoring methods. Summary of the Invention

[0015] See also Figure 1 As shown, this embodiment provides a method for monitoring the wall construction speed before the construction of an anti-seepage wall, which specifically includes the following steps: Step S101: Acquire the construction coordinate position of the TRD equipment in real time.

[0016] Specifically, in this embodiment, the actual construction coordinate position of the TRD equipment is obtained in real time through the GNSS positioning module installed on the TRD equipment. To ensure the accuracy of the positioning data, the GNSS coordinates are collected every 30 seconds (the average value of the received coordinates within the 30 seconds is taken) and defined as , The actual coordinates of TRD construction at the previous moment (the average value of the received coordinates within the previous 30 seconds).

The interface displays the last The speed value calculated during the period.

This method solves the problems of conventional methods in wall construction speed control lacking quantitative basis and being easily affected by human factors, and provides an effective means for the one-step construction quality control of the anti-seepage wall TRD.

Specifically, it includes the following: 1) Real-time construction monitoring data: construction coordinates monitored by the GNSS positioning module; 2) The onboard analysis terminal calculates derived data: analyzing and solving construction status attributes, the start and end timestamps of the effective construction section, and the forward wall speed; 3) User-defined control parameters: Design drawings uploaded by the monitoring client (including the coordinates of the TRD cut-off wall construction axis) and the forward wall speed threshold; The application server determines whether the forward wall speed meets the standard within the time interval based on the forward wall speed transmitted by the onboard analysis terminal and the wall speed threshold transmitted by the monitoring client; if , it means that the forward wall speed is qualified; otherwise, an alarm prompt is issued if the forward wall speed does not meet the standard. The push content includes the abnormality type, coordinate location and handling suggestions; The remote monitoring terminal uses a web login to allow users to view the TRD equipment's construction trajectory and forward wall speed in real time, and supports online modification of forward wall speed control threshold parameters. At the same time, the remote monitoring terminal synchronously receives alarm information sent by the database and application server if the forward wall speed does not meet the standard, and issues an alarm prompt. Specifically, in this embodiment, the remote monitoring terminal (i.e., the monitoring client) uses a web page to log in, and the user can view the construction trajectory and forward wall-building speed of the TRD equipment in real time, and supports online modification of the forward wall-building speed threshold parameters to adapt to flexible regulation of complex working conditions; at the same time, the remote monitoring terminal will synchronously receive the forward wall-building speed failure alarm information sent by the database and application server, prompting the management personnel to take corresponding measures to make adjustments.
