Example one
Referring to fig. 1, a flow chart of a construction method of a honeycomb lattice and graded crushed stone composite base layer provided by the invention is shown. As shown in fig. 1, a construction method of a honeycomb lattice and graded crushed stone composite base course includes the steps:
s1, cleaning and leveling the base;
the base is one of important material bases for constructing honeycomb cells and graded broken stone composite base layers. Only the high-quality base can the construction of the honeycomb cells and the graded broken stone composite base layer be smoothly carried out. Therefore, the advantages and disadvantages of the base preparation are related to the success or failure of the construction of the honeycomb cells and the graded broken stone composite base layer. The main purposes of base cleaning and land leveling are to facilitate the operations of constructing honeycomb cells and graded broken stone composite base course and the like. The soil surface layer of the base should be cleaned of rocks, stumps and the like which obstruct the mechanical operation and influence the construction of the honeycomb cells and the graded broken stone composite base layer. Typically the cleaning depth is about 35 cm. Trees, shrubs, etc. that are not reserved in the planning design should be removed. And (5) according to the planning design requirements, cutting high and filling depressions and leveling the land. When filling the low-lying place, the sinking problem of the filling soil should be considered. The sedimentation coefficient of fine earth is about 15%. When filling, the earth can be pressed or filled to a height higher than the designed height. Before laying honeycomb cells on a base, the base is cleaned and leveled. The cleaning and leveling are from top to bottom to smooth and level the base so that the honeycomb cells can be tightly combined with the base.
Cleaning and leveling the substrate further comprises the steps of: the base of the base is cleaned, and the two sides of the base are subjected to slope releasing treatment to prevent collapse during vibration.
S2, carrying out measurement paying-off on the base;
the measurement and pay-off of the base can be roughly divided into two stages: positioning and paying-off of buildings and paying-off of foundation construction. The positioning pay-off of the building is the first pay-off after the construction of the honeycomb lattice and the graded broken stone composite base layer is started. And (4) positioning according to a building planning positioning diagram (a general plan diagram), and finally forming at least four positioning piles on a construction site. The paying-off tool is a total station or a theodolite. Setting foundation construction setting-out for building positioning piles, setting out foundation engineering, performing measurement recheck, finally setting out positioning piles of all building axes, and setting out all the positioning piles at intervals according to the size of the building and the axes, wherein the positioning piles of all the axes are set out according to at least four positioning piles of a planning department and a building bottom construction plan. The paying-off tool is a theodolite. After the positioning and paying-off of the foundation are finished, a measurer and a constructor on a construction site release a side line of the foundation according to the positioned axis to excavate the foundation. The foundation axis positioning pile needs to be led to a permanent building or a fixed object around a proposed building while the foundation is laid out, so that the axis positioning pile is prevented from being damaged and is used for remediation.
S3, mounting and fixing the honeycomb cells on the base;
the honeycomb cells are formed by high strength welding of reinforced HDPE sheets to form a three-dimensional network cell structure. Some of them punch holes in the membrane sheet as required by the engineering. The honeycomb cells are light in weight, wear resistant, stable in chemical performance, light-oxygen aging resistant, acid and alkali resistant, and suitable for different soil conditions such as soil and desert.

Therefore, the advantages and disadvantages of the base preparation are related to the success or failure of the construction of the honeycomb cells and the graded broken stone composite base layer. The main purposes of base cleaning and land leveling are to facilitate the operations of constructing honeycomb cells and graded broken stone composite base course and the like. The soil surface layer of the base should be cleaned of rocks, stumps and the like which obstruct the mechanical operation and influence the construction of the honeycomb cells and the graded broken stone composite base layer. Typically the cleaning depth is about 35 cm. Trees, shrubs, etc. that are not reserved in the planning design should be removed. And (5) according to the planning design requirements, cutting high and filling depressions and leveling the land. When filling the low-lying place, the sinking problem of the filling soil should be considered. The sedimentation coefficient of fine earth is about 15%. When filling, the earth can be pressed or filled to a height higher than the designed height. Before laying honeycomb cells on a base, the base is cleaned and leveled. The cleaning and leveling are from top to bottom to smooth and level the base so that the honeycomb cells can be tightly combined with the base.
