Description

TECHNICAL FIELD

[0001] The utility model relates to a pipe jacking construction technology field, and specifically is a pipe jacking construction simple operation system. BACKGROUND

[0002] In the continuous development of urban underground pipe network construction and maintenance, pipe jacking construction becomes a key technical means for ensuring the normal operation of the city and reducing the interference to ground transportation and environment due to its non-excavation characteristics. In the pipe jacking construction process, the transportation of various types of sporadic materials such as pipe jacking equipment and pipe materials is crucial. When facing a caisson construction scene, since the caisson usually has a certain height, how to safely and efficiently transport the materials to the bottom of the well becomes a big challenge.

[0003] At present, the conventional method is to use a crane to hoist the materials from the ground to the bottom of the well. In the case of small lifting operation task quantity, this method can still meet the demand. However, once the pipe jacking project is large in scale and long in construction period, the frequent use of the crane will lead to a sharp increase in the number of crane shifts. The cost of crane shifts is not small, which undoubtedly greatly increases the construction cost. For example, in some large municipal pipe jacking projects, due to the use of cranes to hoist materials, the mechanical shift cost accounts for a large proportion of the entire project cost, which seriously compresses the project profit space.

[0004] In addition, the crane operation also has efficiency problems. The hoisting speed of the crane is relatively limited and is greatly affected by factors such as weather and site space. In adverse weather conditions such as strong wind and heavy rain, crane operation may even be forced to stop, further delaying the construction progress. At the same time, if the space layout of the construction site is not wide enough, the parking and operation of the crane will also be limited, affecting the smooth progress of the hoisting operation.

[0005] In view of the high cost, low efficiency and other disadvantages exposed by the traditional use of cranes to hoist materials for pipe jacking construction, it is urgent to develop a new pipe jacking construction simple operation system. The system needs to effectively solve the material transportation problem, significantly reduce the construction cost and improve the construction efficiency under the premise of ensuring the construction quality, so as to adapt to the increasing demand for underground pipeline construction and promote the further innovation and development of pipe jacking construction technology. SUMMARY

[0007] The specific scheme of the utility model is: a pipe jacking construction simple operation system, comprising: a caisson, a fixed platform is arranged at the upper end of the caisson, the fixed platform is a square concrete foundation, a hoisting mechanism is arranged at the upper part of the caisson, the hoisting mechanism is used for hoisting a steel pipe outside the caisson, a pipe jacking mechanism is arranged at the bottom of the caisson, and the pipe jacking mechanism is used for pipe jacking construction of the steel pipe.

[0008] The hoisting mechanism comprises:

[0009] Two parallel columns are arranged on the fixed table, and horizontal beams are arranged at the upper ends of the columns, the middle portions of the horizontal beams are fixedly connected with the columns, cross beams are arranged at the two ends of the horizontal beams, and the two ends of the cross beams are fixedly connected with the horizontal beams; track beams are arranged at the bottoms of the cross beams, one end of each track beam is located directly above the caisson, and the other end is located outside the caisson, electric hoists are arranged on the track beams, and the electric hoists can move on the track beams and hoist the pipelines.

[0010] Further, the pipe jacking mechanism comprises:

[0011] A guide rail is provided with an arc-shaped groove for positioning the steel pipe;

[0012] A foundation back wall is arranged on one side of the guide rail and connected with the caisson;

[0013] An equal-thrust hydraulic jack is arranged between the foundation back wall and the guide rail and used for pipe jacking construction of the steel pipe placed in the arc-shaped groove of the guide rail.

[0014] Further, two support tables are arranged outside the fixed table, two support columns corresponding to the columns are arranged on the support tables, and the upper ends of the support columns are fixedly connected with the horizontal beams.

[0015] Further, two inclined pull rods are arranged between the support columns and the columns, and the two inclined pull rods are cross-symmetrically arranged, the bottom end of one of the two inclined pull rods is fixedly connected with the column, the bottom end of the other inclined pull rod is fixedly connected with the support column, and the upper ends of the two inclined pull rods are fixedly connected with the horizontal beams.

[0016] Further, foundation bolts are arranged on the fixed table, and the columns are fixedly connected with the fixed table through the foundation bolts.

[0017] Further, the foundation bolts are L-shaped foundation bolts.

[0018] Further, two intermediate beams are arranged in the middle of the horizontal beams, one of the two intermediate beams corresponds to the support column, and the other intermediate beam corresponds to the column.

[0019] Further, the track beams are I-shaped steel.

[0020] The utility model has the following beneficial effects:

[0021] 1. Simple structure and convenient installation and debugging: The pipe jacking construction simple operation system of the utility model discards the complex structure of traditional equipment and adopts a simple design concept. For example, the hoisting mechanism is composed of upright columns, horizontal beams, cross beams and track beams arranged in parallel, and the connection of each component is clear and understandable. Compared with traditional large pipe jacking equipment, the installation process does not require professional personnel to spend a lot of time on complex assembly and debugging, greatly shortening the preparation time before construction, enabling the project to enter the construction phase faster, and significantly improving the construction efficiency.

[0022] 2. Significant cost advantage: From the equipment purchase and rental cost, the simple operation system has a simple structure, and the required materials are common and relatively low in price. Whether purchased or rented, the cost is much lower than that of traditional large equipment, providing a feasible solution for small projects with tight budgets. During the construction process, the labor cost is also reduced accordingly. At the same time, the system reduces the dependence on large mechanical equipment and reduces energy consumption costs, achieving effective control of costs in all aspects.

[0023] 3. Strong ability to adapt to complex construction environment: In space-limited areas such as old urban areas and narrow streets, traditional large pipe jacking equipment is difficult to operate due to its large size. The simple operation system has relatively small components, which are easy to assemble and operate in narrow spaces. In addition, in projects with strict noise and dust pollution control requirements, the noise and dust generated during the operation of the system are much lower than those of traditional equipment. For example, the pipe jacking mechanism uses equal-force hydraulic jacks, which can effectively reduce noise interference to the surrounding environment compared to the high noise of traditional equipment during operation, meet environmental protection requirements, and greatly expand the application range of pipe jacking construction technology in different complex environments.

[0024] 4. Improve construction efficiency: Through the coordinated operation of the optimized hoisting mechanism and pipe jacking mechanism, the simple operation system can realize fast hoisting and efficient pipe jacking. The electric hoist in the hoisting mechanism can move flexibly on the track beam and quickly lift the pipe, and the guide rail and equal-force hydraulic jack of the pipe jacking mechanism work closely to ensure accurate and efficient pipe jacking, effectively reducing the downtime and delay during construction, improving the construction efficiency, and ensuring that the project can be completed on time or even ahead of schedule.
