The invention relates to the technical field of devices for construction, in particular to a crawler-type cutterhead earth pressure balance rectangular push bench and a construction method thereof. The crawler-type cutterhead earth pressure balance rectangular push bench comprises a shell, an earth bin and a power bin, wherein a screw conveyer is arranged in the earth bin, a power transmission device is arranged in the power bin, metal crawlers are arranged on the end face of the body of the push bench in a partitioned mode, earth cutting tool bits are fixedly arranged on the crawlers, and the crawlers extend into the soil bin from the end face of the body of the push bench and are connected with frequency modulation motors in the power bin. According to the crawler-type cutterhead earth pressure balance rectangular push bench and the construction method thereof, a plurality of crawlers are arranged at the end of the body of the push bench symmetrically, when the crawlers run, a soil body can be cut by the tool bits fixed to the crawlers without dean angles. Because the rotation speeds of the crawlers arranged at the end of the body of the push bench are adjusted in a partitioned mode, earth does not evenly get out on the end face of the body of the push bench, earth pressures on the end face of the body of the push bench can be different, and deviation rectification force is generated. According to a traditional push bench, deviation rectification is carried out with a jack in a jacking force adjustment mode, and compared with the traditional push bench, the crawler-type cutterhead earth pressure balance rectangular push bench has one more way for deviation rectification.
