The invention relates to a construction method for oblique tunneling of a rectangular pipe jacking machine in a closed space. The construction method is characterized by being composed of the following steps of: sealing a receiving well; sealing a channel access by a rigid retaining wall and backfilling yellow sand by the receiving well; layering and backfilling; paving a steel plate as a platform for the pipe jacking machine to horizontally move; chiseling edge backfilled soil at a concrete edge of a tunnel portal for tunneling; adjusting each parameter and tunneling the pipe jacking machine; stopping and positioning the rectangular pipe jacking machine after tunneling the rectangular pipe jacking machine; grouting pipe sections of a tunnel portal section and closing the tunnel portal; cleaning earthworks and horizontally moving the rectangular pipe jacking machine; straightening the rectangular pipe jacking machine to horizontally move and hoisting in a hoisting hole. The construction method for the oblique tunneling of the rectangular pipe jacking machine in the closed space has the advantages that: the large-angle oblique tunneling problem is solved through the construction; the closed space is formed by backfilling the sand and the soil through the space of a structure of a station and a front cabin has soil pressure in the tunneling process, so as to reach the soil pressure balance; and in the tunneling process, phenomena of water leakage and sand leakage do not happen and conditions of damaging pipelines and grounds of a tunneling region do not occur.

The invention relates to a rainy season roadbed earthwork construction structure and a construction method thereof, and relates to the technical field of road construction. The construction structurecomprises a drainage assembly arranged in a settling well; and the drainage assembly comprises a drainage pipe and a hollow filter box, wherein the drainage pipe is communicated with the filter box, and a plurality of filter holes are formed in the side wall of the filter box. During use, the drainage assembly is installed in the excavated settling well, and the drainage pipe is communicated witha municipal pipeline; in the rainy period, rainwater is discharged into the settling well, a large amount of silt in the rainwater is settled to the bottom of the settling well, then, the rainwater enters the filter box through the filtering holes, and finally, the rainwater is discharged into the municipal pipeline through the drainage pipe, so that the rainwater is effectively prevented from being directly poured into the foundation pit to influence construction; and meanwhile, the filtering holes play a role in filtering rainwater, so that a large amount of silt or leaves and other garbageare prevented from entering the municipal pipeline, smooth drainage of the municipal pipeline is guaranteed, the possibility of water accumulation is reduced, and normal construction after raining canbe guaranteed as soon as possible.

The invention discloses a method for preventing upward floating of an existing tunnel during unloading of earthworks, and relates to a foundation pit construction method. The method includes the stepsthat the range and depth of the earthworks needing to be unloaded above the existing tunnel are determined, soil bodies on the two sides of the existing tunnel and located at the peripheries of the earthworks needing to be unloaded are excavated till the depth determined in the step 1, two construction areas distributed on the two sides of the existing tunnel are formed, pile bodies are constructed in the two construction areas correspondingly, pipe-jacking construction is conducted on the bottom of the earthworks, needing to be unloaded, between the two construction areas on one of the two construction areas, a pipe-jacking channel is formed, jacking beams are constructed in the pipe-jacking channel and connected with the pile bodies constructed in the step 3 to form bench piles crossingthe existing tunnel, and after the bench piles are formed, the earthworks needing to be unloaded are excavated. According to the method provided by the invention, the defect of upward floating of theexisting tunnel during unloading can be effectively prevented, and operation is easy.

The invention discloses a large-area dredged dredger fill foundation structure and a treatment method thereof. The large-area dredged dredger fill foundation structure comprises a plurality of supporting columns and cross beam cement boards; the cross beam cement boards are connected through the supporting columns; V-shaped connecting frames are connected between the supporting columns; dredged soil is arranged at the top and the bottom of each V-shaped connecting frame; steel frames and first concrete are arranged in the supporting columns; and the V-shaped connecting frames are provided with multiple steel bar frames and second concrete. According to the structure, dredged soil and concrete are fully combined, so that the stability and firmness of a foundation are improved, the overall service life is long, the dredged soil does not need to be conveyed out, filling of other soil is not needed, the building cost is saved, and the building period is shortened; dredged soil is divided into a plurality of regular triangles and inverted triangles, and the regular triangles and the inverted triangles are separated through the V-shaped connecting frames; and water drainage holes and water guide grooves are connected, so that all dredged soil earthworks can be connected, water drainage is conducted, and the problem that a foundation sinks does not need to be worried about.
