The construction method for enveloping and splicing the prefabricated square culvert foundation and the cable trench foundation according to claim 6, wherein the second controller obtains that the angle difference between the i +1 th formwork and the i-th formwork is within a preset value range, and the second controller adjusts the rotation angle of the i +1 th formwork second supporting device and the fourth supporting device, wherein the i +1 th formwork second supporting device angle θ p is increased to θ p2, θ p2= θ p x (1 + | R (i + 1) -Ri-R0 |/R0), the i +1 th formwork fourth supporting device angle θ p is decreased to θ p4, and θ p4= θ p x (1 + | R (i + 1) -Ri-R0 |/R0).
10. The construction method for enveloping and splicing the prefabricated square culvert foundation and the cable trench foundation according to claim 5, wherein the second controller sets a standard parameter θ 0 of rotation angle, and adjusts the obtained dynamic parameter Lq of the supporting device according to the rotation angle of each supporting device,
when θ pm ≧ θ 0, the second controller increases the supporting-device power parameter Lq to Lq1, sets Lq1= Lq × (1 + (θ pm- θ 0)/(θ pm × θ 0)),
when θ pm < θ 0, the second controller decreases the supporting device power parameter Lq to Lq2, setting Lq2= Lq × (1- (θ pm- θ 0)/(θ pm × θ 0));
wherein p =1,2,3,m =1,2,3,4,q =1,2,3,4.
